How to Escape the San Diego Garden Doldrums

December 22, 2015 By Christiane Holmquist

Integrate your garden into the larger xeriscape that is our San Diego County.

(It could spell more fun and savings than you expected.)

How to escape the SoCal garden doldrums

Grounded: Desert plants evoke our Anza Borrego desert; DG and boulders connect with the Mission Hills behind the house

With approaching retirement and more time to travel, Jeanie and Jim realized that their traditional garden didn’t seem to allow them much time away; it just didn’t respond well to weeks of absence. When they called me, I found that they begun to add to their traditional home landscape design many new-found loves: Various Aloes and Sticks on Fire Euphorbia, Organ Pipe and Barrel Cactus, ‘Bells of Fire’ Tecoma, Crown of Thorns and other xeriscape plants.

With their list of collected plants I was handed a clear mandate: Remove the old lawn, the worn-out shrubs and even the Queen Palms; create a drought resistant landscape, lively and evoking our local Anza Borrego desert, yet not too spiky and withered looking, that would be easy to maintain and allow them weeks of absence without needing human intervention.

Front yard Before

Here’s their testimony about our adventure together:

What was the biggest motivator to transform your garden?

“We have always enjoyed succulents and the desert landscape, so we wanted both our front and backyards to look like the desert that we love. Also, due to our continuing drought situation, it made sense to convert to a low water landscape to save water. Additionally, the biggest motivator was to reduce our work in the yard: mowing would no longer be necessary. As we travel and are gone for extended periods of time, we wanted a landscape that was virtually maintenance-free during our absence.”

Above, the old lawn is more or less gone, with palms being ‘statuesque’

So where do I begin a landscape design renovation?

I imagined the entire garden as ‘playground’ for all the exotic drought resistant plants that Jim and Jeanie dreamt of. To display these plants to their fullest, the tilted surface of a mound would be useful; also, the mildly undulating terrain would bring some movement into the “flat” scene.

The new back Yard design provides more entertainment space and greater visual pleasure.

During our brainstorming the desire for ‘more entertainment’ were mentioned, so for the backyard I designed an extension of their patio, surrounded by seat-walls for casual overflow seating. Behind these walls, the terrain was also be mounded to give the planter bed here greater movement. Many of their desert plants were put here to which I added a few well-tested perennials and grasses: Sundrops Calylophus, Verbena ‘De la Mina’, California Fuchsia Epilobium and Angelita Daisy Hymenoxis. While the textures and forms of the desert plants are more permanent, the perennials and grasses would add a notion of seasonal decline and re-growth.

To these I added various Agaves, Rushes, grasses and Red Yuccas; also fluffier and softer foliage plants, such as Emu Bush Valentine Eremophila, and Texas Ranger Lynn’s Legacy’ Leucophyllum, chosen for its silvery foliage and light purple flowers that would offset well against the yellow and orange flowers of Senna, Tecoma and Palo Verde. I used creeping Elephant’s Food Portulacaria as an attractive groundcover and the grass-like Bulbine because of its flowers that attract bees year-round.

Still in their infancy, plants begin to take their place in this scene.

For me, Jim and Jeanie’s project was very satisfying; having clients who so clearly appreciate where they are, love region-appropriate plants and are open to a professional landscape designer’s suggestions makes always my job most pleasurable.

DG as top dressing, boulders and xeriscape plants give this garden a strong regional and authentic character.

Here’s how Jeanie and Jim think about the experience:

What was your biggest and best-appreciated result?

“With careful plant selection, hardscape, lighting and other elements of the garden, we feel it was a success and we’re proud of having a really great yard. An unexpected bonus is the many compliments received from neighbors.”

To this I would add: With the boulders and the mounds as top dressing Jeanie and Jim have expressed their appreciation for our dry environment, but foremost they linked their garden with the rugged hills of Mission Trails Park across the canyon. The plants they love and the chip seal (a coarse DG) do another to give their garden a strong regional and authentic character.

What is your greatest pleasure now, or the thought or feeling most often felt when walking through your garden?

“We really enjoy the variety of our plant selection with the many colors, textures and shapes. Using DG (decomposed granite) as topdressing mulch allows the plants to really “pop out.” Over the last year we have witnessed the growth and color changes of the plants realizing that the landscape feels more alive and ever-changing than just a static lawn. We also appreciate the hummingbirds and bees that visit regularly.”

Any lesson learned or any other thought that you care to share with the readers?

“We learned: In drought situations, drip irrigation is the best way to conserve water. Landscape lighting is extremely important. Anyone undertaking this type of project should get the best lighting they can afford since it makes the project exceptional as the landscape is not only admired during the day, but it is just as impressive in the evening. (We highly recommend Volt LED lighting (available on the internet.) Also, it cost us twice as much as we originally thought during the early planning stages. Hardscape, lighting and other changes made during construction drove our costs up, but we are so pleased with the results that we would do it again. “

How to escape the SoCal garden doldrums

Colorful and interesting; lawn-be-gone!

Looking back at this project and considering the short time in which this garden has continued to grow, another idea comes to mind:

In southern California, it is sometimes hard to remember what time of year it is, but it is especially important to do so now: days are getting shorter and cooler: we need to remember how our bodies respond by storing more food, by changing sleep patterns and energy levels, by changing moods. A garden should be a natural environment, one that changes with the seasons and reminds us of our place in the web of life and of its cyclical nature. Those clipped lawns and shrubs surrounding our office buildings may provide us with a glimpse of green, if we are fortunate enough to have a window to the outside, but they leave us with little comfort and warmth when our lives change. If we get married, or divorced, have an accident, grow old, start a new career, buy a house, lose a friend etc., a static landscape may feel even more alien and uninviting if it mocks our changing natures.

What we seek in a garden is a reconnecting with the relish we relive every year, in the first days of spring when plants are just beginning to flower again, or on a warm day in fall, out at the edge of a clearing in the forest, that fills us with peace and amazement at how beautiful even small things can be: it can be a great comfort in times of change. Building a drought tolerant landscape is an opportunity to connect with the beautiful natural environment of San Diego County, and to let the seasons and change back into our lives.

Get ready for a promising planting season: Here are some beauties for plant-aholics to drool over Part I

October 4, 2014 By Christiane Holmquist

Roger’s Red Grape

Roger’s Red Grape

The recent untimely heat wave is barely forgotten, but I‘m noticing the first signs that many of our water-wise plants have awakened from their summer beauty rest: Their green branch tips and new leaves are proof that they are actively growing again.

With the cooler nights and fresh breezes announcing fall, my impatience is growing to be out in the garden; I’d want to be planting and trying out some of the exciting plants that I have noticed in the recent months and that I could barely stop myself from buying.

The gardeners among us know that there’s always room in our gardens to improve and tweak, to improvise and create, or to replace those plants that have proven to be not so sturdy or are otherwise unsatisfactory. This provides us with a welcome excuse to compile our wish list, research these plants and see which ones we’ll fall for this year!

With plant sales happening now and some great growers offering their new releases, it would be easy to get carried away and come home with trunks full of exciting plants. I have done this myself and given in to plant cravings that I later regretted: A garden that is a collection of plants can look really disjointed, and I have come to prefer a garden that shows a theme and some continuity, and repetition of colors and textures does make for more soothing calm.

So with the following list I hope to highlight a few of the plants that make me drool. Besides drawing from my own notes, I have asked a couple of landscape designer friends to share their favorites.

All these plants have many wonderful attributes in common: They are xeriphytes from all over the world that share many desirable attributes: They are drought resistant plants (also marketed as “waterwise plants”), hardy, with a good structure and undemanding in maintenance (that includes fertilizer and pruning) and provide year-round interest.

Landscape Designer Marilyn Guidroz of Marilyn’s Garden Design says:

Drought Resistant shrubs

Leucophyllum langmaniae ‘Rio Bravo’ Texas Ranger ‘Rio Bravo’

‘Rio Braco’ Texas Ranger is a fast growing, dense screen shrub that needs no pruning after the initial shaping to become established.  At maturity it reaches 5 ft ht x 5 ft wide.

This is a drought tolerant shrub that only requires a once a month deep watering in the summer months once it is established.

The lovely lavender flowers cover the shrub in intermittent waves during the hot humid months of summer and fall.  [In my experience in dry summers, the flowers are more sparse.] The evergreen foliage is a soft mint green all year long.

I like to use this plant as a dry garden border, a screening shrub and a colorful focal accent.

drought tolerant plants

Vitex californica ‘Rogers Red’ Grape ‘Roger’s Red’

This is my favorite fall color plant.  It is great as a screen on fencing.  It takes moderate water and can even handle regular water if in an area that receives more.  It is best in full sun and can handle partial shade.  A deciduous native plant that has edible fruit and climbs by tendrils.  Has gray-green leaf color all summer and then turns brilliant red in fall.

Owner/landscape contractor Mark Sterk of Columbine Landscape Inc. recommends:

drought tolerant shrubs

Rosmarinus ‘Roman Beauty’ Roman Beauty Rosemary

Rosemary ‘Roman Beauty’, dwarf to 2’, they say, and grows in an upright, roundish form that is consistent and easy to keep in place. It also has a more graceful appearance and a bit of a different color than the usual look.

Here’s more about ‘Rosmarinus officinalis ‘Roman Beauty’ (‘Roman Beauty Rosemary):

A compact and slow growing semi-upright Rosemary with slightly arching stems bearing narrow mid-green leaves and violet-blue flowers in late winter and spring. This plant will likely get somewhat larger but 2 year old plants only measured 16 inches tall by 12 inches wide. Plant in full sun. As with other Rosemary it is resistant to deer and rabbit predation, tolerant to salt spray, alkaline soils and drought. Hardy to 15°F.

This shrublet could add that “needle-like” element that coniferous plants introduce (great contrast to a rounder, fleshier foliage), or allude to a classic Mediterranean landscape. I’d use it as an important connector and “glue” that, frequently repeated, can hold all your other plants together. (See my previous post about the role of shrubs: Better Beds with Shrubs).

drought resistant plants

Abelia x grandiflora ‘Kaleidoscope’ Glossy Abelia Kaleidoscope

Mark goes on to recommend:

“Abelia ‘Kaleidoscope’ — variegated, dwarf, same kind of form as the Rosemary, but grows to 4-5’, I believe. White flowers, gold variegated foliage — good pop! Not sure if it’s low water, but we’re using it that way and it seems to do well.” (San Marcos Growers list this plant as needing ‘moderate water’.)

Please keep an eye out for my follow-up post where I share more exciting plants that promise to make a great show in your gardens next year.

Also: Next month, October 13, at the monthly meeting of the San Diego Horticultural Society I’ll be one of three landscape designers giving a presentation about design options for those who are considering removing their lawn.

Help! My Gardener is Ruining My Garden! Part 2

August 25, 2014 By Christiane Holmquist

In this post I continue to examine how to protect your garden’s beauty and value and how to avoid maintenance headaches.

maintenance service

Communication with the maintenance service

Things to review with the supervisor:

  • Let the supervisors know of your preferences (see above).
  • Can they explain the irrigation system to you so that you can run the timer yourself if you so choose? (In fact, it is absolutely essential that you understand your irrigation system and do periodic check-ups on timing. This way you remain aware of the seasonal changes in your landscape’s water demands or determine the irrigation cycles yourself in an emergency.)
  • Do they plan regular walk-throughs with you?
  • How easy is it to reach the supervisor, and how promptly do they respond to an emergency?
  • How often is the supervisor on the site? If not regularly, how trained are the maintenance workers?

Soil and Irrigation

Many of the gardens that I see suffer more from over-watering than from too little water (the symptoms = wilting and tip die back look pretty much alike initially). It seems particularly tricky to water “infrequently but deeply” and then letting the top 3-4 inches dry out between irrigation cycles…

Aeonium Cabernet

This Aeonium Cabernet is showing signs of summer dormancy with leaves dropping along the stems; if it gets overwatered now, the stems will get ‘mushy’ and wilt, and the plant will die from the center out.

I’d ask the maintenance professional about their familiarity with modern irrigation technology: Are they open to contemporary components such as a “smart” irrigation controller that helps you calculate water needs?
Also: Taking a soil tests with an auger or ‘soil tube’ should happen at regular intervals on a job site; it helps determine the moisture content of the soil as well as possible rot or pests.

Interfacing with Other Specialty Service Providers

Will the maintenance integrate their services with other specialty providers, such as arborists, irrigation specialists, or plant pathologists as the case may require? (Do they perhaps have their own certification in arboriculture?)

Outdoor Lighting

Can they also repair outdoor lighting? Perhaps even install it as a retro-fit?

Mulch

Do they know the value of proper mulching, and will they vouch to keep it at the height specified in the design?

mulch

Here, two different mulches were used as organic groundcover between the plants and as pavement for the walkway, outlined with black aluminum.

Weeds and Invasives

Do they know their weeds? Will they pull a Mexican Feather Grass before it goes to seed?

mexican feather grass

Stipa tenuissima Mexican Feather Grass is a popular ornamental grass that has been recognized as very invasive.

Will they recognize an Oak seedling, or some other invasive plant species, such as Salt Cedar?

salt cedar

A Salt Cedar can be an attractive shrub that is highly invasive with many attributes that are harmful to our natural environment.

Plant Expertise, Training and Certification

Of the many local landscape maintenance service providers that I checked online some mention their training in pest control and fertilizer applications; few however list training in horticulture (which would include knowledge of new plant introductions for Southern California’s limited water resources), irrigation or arboriculture.

xeriscapes

Here, in its 2nd summer after installation, plants are beginning to fill in, and the textures and forms are taking shape.

As our understanding of xeriscapes deepens and our appetite for exciting low water-use plants from South Africa, South America, Australia or our own south-western states grows, more and more nurseries and growers offer these, and what was exotic five years ago is becoming common-place in our new gardens.

Here are some important questions for the maintenance candidates:

  • Is their knowledge of standard and new introductions of low-water use plants up to speed?
  • Are they aware of current trends and tools of the industry?
  • Do they have any training in ornamental horticulture principles and maintenance standards (“specialty” pruning of trees and shrubs included)?

This training is locally available, through many community colleges or organizations in the landscape industry: The California Landscape Contractors Association (CLCA) and the Professional Landcare Network (PLANET) are two of the leading professional associations that test and certify members of the green industry. Landscape Industry Certified Technicians have proven their know-how to do the job right. They have passed a series of written and hands-on tests covering safety and technical aspects of the job.

Seasonal Color

If you need seasonal or special occasion “color splashes” into your garden, ask the service provider if they could be counted on providing these services.

References & Licenses

Before you entrust this maintenance company with your property,

  • Ask for several reference addresses and visit these;
  • Ask whether they have a training program for their employees, and what it consists of;
  • Do they have any type of certification from an accredited learning institute in the horticultural industry?
  • Talk to at least two if not three of their clients to get a good sense of the responsiveness and quality of this candidate.
  • At a minimum, ask for letters of appreciation from their previous work.
  • Your maintenance company should be licensed and insured; without it, you might be liable for any damages or injuries that they sustain on your property (and your homeowner’s insurance won’t cover you here).
  • All these qualifiers exclude the “mow-and-blow” crews… It’s unfortunate that they haven’t done much to not deserve this name.

The Long Haul

A garden will never be ‘finished’, yet that it will grow and evolve. In order to protect the investment that you made into your landscape, much consideration goes into the selection of your maintenance service. Will they commit to helping reach a beautiful goal over time and to not let short-term interests ruin it? And will they continue to loyally support you with honest professionalism as your garden grows and matures?

These are surely questions worth asking. Read part 1 of Help! The Gardener is Ruining My Garden.

Help! My Gardener is Ruining My Garden!

July 25, 2014 By Christiane Holmquist

my gardener is ruining my garden

Ingredients for your own Eden: Take a bit of space, add an inviting piece of furniture, surround with a beautiful plant screen and groom well.

Just recently I got an SOS call from a client who is desperate to find help with a nightmare she is experiencing with her present maintenance company: Plants in various states of wilt or decay, with bare spots in the landscape; succulents drowned, groundcover smothering everything in its way, and most offensively, “alien” plants willy-nilly planted, presumably as substitutes, that have nothing to do with her landscape design and that she never approved.

dead groundcover

A sorry sight: There are bare spots on this slope where the groundcover died; the succulents are the wrong ones, and other plants are missing from the original design.

She is very upset that the trust that she placed in her grounds-person was wasted and is worried that the quality of her landscape is seriously endangered. As I’m working out a plan to help her, the horror litanies from other clients come to mind: “My landscaper has hedged this shrub into a blob although I told him to leave it alone”, or “My gardener doesn’t know how to prune these perennials”, and “My slope is all washed out and plants are dying on it; should I just pave it over?” and “I don’t know why he chopped my tree”.

Obviously, these home owners don’t have a maintenance company that is well trained; their crew’s work might actually harm the long-term health and beauty of the landscape, instead of safeguarding their investment.

spotty irrigation

Spotty irrigation has caused bare spots in the lawn; shrubs under the trees have been pruned into unnatural shapes.

For these homeowners it is frustrating to realize that, after several years of ‘care’ by their gardening service the actual state of their landscape is far removed from the one they once dreamed of. What happened to original design intent? How is it possible that these landscapes are ‘monotonous’, overgrown or disfigured? Obviously, the regular mowing, weeding, trimming and blowing weren’t what was needed. What went wrong?

Perhaps it helps to consider the type of gardens that we want today: In my view, the showcase gardens (most often lawn-centered) in which we display exceptional roses, exotic palms or other specimen plants are no longer relevant, at least here in Southern California. On their way out also are the gardens designed with stately foundation plants around a lawn that highlight our social status, or that are plain buffer-zones between us and our neighbors.

The gardens of today that many people dream of are extensions of our living spaces. Here we play and entertain, relax in privacy and seek a modicum of nature. For our landscapes to become true sanctuaries to recharge in, we need to create gardens that engage our senses. These are no longer areas to be tamed and trimmed but places to work in with nature, using light, rhythm, space and texture, and where we respect and enjoy the changes that come with time.

Watersedge-Landscape-Design3

A beautiful example of what excellence in maintenance can achieve. Photo courtesy Watersedge Landscape.

So how do we find this maintenance professional who understands this and who will respect the original intent of the design, and who will safeguard our investment? Who nurtures the landscape, rather than whipping and hedging it into shape? Who we can rely on to insure that the landscape matures and thrives as planned?

Communicate with your designer

shrubs

The shrub by this front door is just too big, and its maintenance will eventually result in suppressing its growth leading decline and eventual death. This obviously was not the best design choice.

When you create your landscape plan (whether with the help of a professional designer, or with your own energy and creativity), you will have the opportunity to consider many elements that will inform the design and that ultimately will determine the amount of maintenance:

  • How controlled do you like the plantings to be? More formal, or more naturalistic?
  • What feel? Urban, woodsy, tropical, southwestern, California relaxed, formal Mediterranean, etc…
  • How densely do you like it planted? With a dense plant cover, or more with recognizable “individualistic” plant quilt?
  • Are you comfortable with the old standards, or do you prefer new exotics?
  • Do you like the natural, relaxed shape of shrubs that sometimes can be picturesque with unusually angled branches, or do you prefer it tight and controlled?
  • Would you be a friend of seedheads, or do they look too weedy to you? (Many perennials require regular deadheading to look good and keep blooming.) Can you stomach wispy grasses, or do you want them at all times neat and clean looking?
  • What type of growth on your trees can you expect (this will tell you how soon you need to consult an arborist)?
  • How will the garden look right after installation; what look can I expect at maturity and how long might it take to see a definite change towards fullness of growth?
  • Which plant is supposed to be a single-stem plant; which one will need to be trained into multi-trunk specimen?
  • Who is going to do the maintenance? You yourself, or a maintenance service? Are you interested in protecting your garden, or would you think that the type of work needed in your garden requires specialized training and education?

Your responses to these questions help determine the selection of plants and the amount of maintenance. It will then be important to communicate this design intent to the maintenance service.

These questions will also influence your selection of the right maintenance company that has a track record of doing quality work.

barren slope

A barren slope despite of regular irrigation… Most likely the irrigation water was applied so fast that it ran off before it had time to sink into the earth… which left plants on this slope to die from thirst.

In my next post I’ll write about the other pieces of the maintenance puzzle.

Beautiful drought tolerant garden in San Marcos

June 30, 2014 By Christiane Holmquist

drought-tolerant garden in San Marcos

This landscape was transformed from lawn-centric static space into a living garden designed for outdoor living.  It is colorful and entertaining year round, and invites to enjoy and relax, play and garden.

Shade trees and pergola

 We transformed the yard into a drought resistant landscape with room for many activities: A patio roof and shade trees make outdoor living comfortable; with play lawn and plenty of garden beds (both homeowners are avid gardeners) there’s room to play outdoors year round.

A colorful waterwise landscape is more to the homeowner's liking

PROJECT SUMMARY: After sitting down with the homeowners, we opted for lawn-removal in front and kept only a minimum of lawn in the backyard for the children to play on. With this landscape re-do, the homeowners have reclaimed their front yard and created a private “buffer zone” at their front door. The homeowners are passionate gardeners, so we significantly increased their garden space and filled it with exceptional drought resistant plants.

  

We replaced the paving material of the existing terrace with a tumbled paver placed on sand and added a shade structure.  Although the terrace was reduced in size, it is comfortable for the many uses of this family, and the large shade cover creates lovely dappled shade in this space. A wrap-around seat wall invites garden visitors to observe the plants and the fish in the small pond placed at the edge of the terrace for close-up viewing.

A low water landscape after the renovation

As the trees grow, they will not only cool the entrance and protect shade loving plants, they will also complement the horizontal lines of the architecture, anchor the house to its site and “shrink” the home to a more human scale.

Tricycle path in the backgarden

To allow more water to penetrate into the subsoil, compacted pervious DG (decomposed granite, a local material) was used to create paths through the garden.  These paths lead to benches and arbors and provide a clean, fast-drying surface to walk on or ride a tricycle.

  Raised beds and DG path

Lush and Waterwise Landscape Design in Carlsbad, CA

November 23, 2011 By Christiane Holmquist

Front garden showing plant-driven design This drought resistant landscaping -  front and back – is lovingly planted with exuberant, dramatic greenery that is a pleasure to care for.  Shady sitting areas, water play features for children and adults, and comfortable walkways made from beautiful materials invite year-round outdoor enjoyment. A stunning example of xeriscape design in San Diego.
 
Overgrown landscape hides modern architecture BEFORE: The front yard landscape design was a plant jumble that obscured the entrance to this modern home and darkened the front yard.

WANTED:  The homeowners desired a low water landscape with low maintenance plants; in addition, these gardens should provide year-round gardening pleasure with plants sculptural and bold enough to hold their own against the striking architecture of the home.

 

 

 plant-driven low water landscape in Carlsbad

From the existing planting scheme we kept the palm trees as accents and overhead canopy.  To this we added terrestrial Bromeliads, Echeverias, Aeoniums and Agaves selected for their dramatic foliage, easy care and permanent allure.  A large Aloe bainesii, Bronze Loquats, Leucadendrons “Safari Sunset” and an exotic Trevisia palmata add weight in the mid-plane of the composition.

 

 

 Vriesea sanguinolenta is a striking terrestrial bromeliad The flower bed designs show a plant combination that works well:  The Leucadendrons, Aechmeas and Vrieseas will need watering every 10 days or thereabouts (this of course after the establishment period). They’ll make good companions to the Agaves, Echeverias, Sedums and Coral Bells.
 

 

A naturally rusted cor-ten steel fountain in the front garden

A sleek re-circulating fountain stands across from the window and can be viewed from inside.  A flat-topped boulder and a chair nearby invite to sit and watch the grandchildren play with the water.

This fountain was fabricated from naturally rusted cor-ten steel.  Water is pumped up from a subterranean reservoir into the fountain trough and sheets over its sides.

 

 

Aeonium Black moon pairs up with Peruvian Lily Although Peruvian Lilies and Iris provide a lot of color in the summer months, most of the visual interest is provided by the permanent textures and colors of foliage plants, as here by the Black Moon Aeonium, variegated Foxtail Agave, Dymondia Silver Carpet and Sedum kimnachii, all very fine drought xeriscape plants.
 

 

 A flagstone path bisects the front garden A flagstone path bisects the front garden, connecting the driveway to the front door and continuing around the house to the back garden. It allows viewing and exploring from all angles and increases the enjoyment of so many fascinating plants.
 

 

Pergola and play lawn invite into the garden

This xeriscape design in San Diego has become a garden with generous and exuberant greenery; there is just enough lawn for grandchildren and dog to play on.  A beautiful flagstone path invites strolling past Mexican Marigolds, ornamental grasses, Rock Purslane, Sundrops and Brazilian Coppertree, to name a few.

 

 

Sandbox and splashing boulder in the shade of the Jacaranda The sandbox was placed under the Jacaranda right next to the pergola, and a “splashing boulder” adds another attraction for children and adults. Now parents and children can enjoy their playtime in the comfort of these shady places.
 

 

Vegetables are planted at the feet of perennials in raised beds The raised beds are holding Roses, Lavender, ornamental grasses and Irises of “her” collection as well as vegetables planted at their feet.  With careful placement and their own irrigation cycle no plant interferes with another, and all are doing well.
 

 

Under water world suggested by succulents and cacti Fantastic succulents and cacti evoke a world of other-worldly marine creatures that was inspired by the “sea-scape” created at San Diego Botanic Garden by Jeff Moore, Owner of Solana Succulents. Red Octopus Aloe, Myers Asparagus Fern, Star Fish Aloe and Medusa Plant were set into two earthen mounds decorated with scree, lava rock and boulders to evoke a coral world populated with sea weeds, anemones and star fishes.
 

 

Plants are partners in this garden with man and man-made structures Partners in this project:  Mark Sterk of Columbine Landscape, Escondido, CA, one of the finest landscaping companies in San Diego, executed this project with a never-tiring attention to detail, creative problem solving and absolute dedication to quality performance. Rancho Soledad Nursery, Rancho Santa Fe, CA provided the “exotics” (Vrieseas, Aechmeas, Agaves, Echeverias). Green Meadow Growers in Bonsall, CA provided perennials and succulents. Solana Succulents provided the plants for the “sea scapes”. This is truly a breath taking example of xeriscape in San Diego.

The lawn needs to go – but what then? Water Conservation Issues and Garden Re-do addressed at “The Garden”

March 24, 2011 By Christiane Holmquist

boulder scene in late afternoon with succulents and drought tolerant shrubsrelaxing chair under tree amongst grasses and perennials

Prompted by the rising water cost and irrigation restrictions, San Diego homeowners consult the many resources available the Water Conservation Garden in El Cajon (at www.thegarden.org ).  Among these resources are landscape design and horticulture experts offering consultations on subjects like “California Friendly Plants”, watering, arboriculture (the science concerned with trees),  construction issues and landscape design. I enjoy being one of those professionals, and I thought you might be curious to learn how such a consultation might work for the people that come there. 

succulents and perennials adorn boulderIn my consultations I generally encounter the same objective:  Feeling the need to reduce their water bill or wanting a landscape that is more practical and ecological,  these homeowners are ready to retire their mostly lawn-centered landscape.  They come to the Water Conservation Garden with the common question,  “What do I plant now?”   Most of them believe that planting the right plants would make their gardens better and solve their problems; isn’t that what the beautiful low-water-use plants at “The Garden” are all about?

I understand this thinking but, as designer and horticulturist, I don’t think that suggesting different, albeit drought resistant, water-wise  or “xeric” plants, would address the underlying problem (although those plants are generally more sustainable).   I feel that planting random groups of plants into the former lawn area would not create attractive, comfortable spaces for outdoor living that “work”.  Since that is my focus, I explain to the visitors that it would serve them best if they considered first how to make enjoyable outdoor living possible, in separate spaces designed for different uses.

What needs to happen in a yard so it can become an “outdoor living room”?  How do you convert it into a play room, or entertainment space, a space to hang out, relax, dream, rejuvenate? 

A garden space needs to be organized spatially and hierarchically, and I start my design process, in which I involve my visitors, by asking them if they can think of an activity that they would like to do but never had room for or that was relegated to a back corner of their garden.  Perhaps there is some almost forgotten vision of a garden scene in the recesses of their memory that they never took seriously?  Take the example of my last visitors at the Garden:

This family, husband, wife and son, arrived well prepared for the consultation, with photos and a sketch of their garden drawn to scale. They had decided to take out most of the lawn, a large expanse right by the patio; they would only keep a small part of it for their son for whom lawn mowing is a therapeutic activity.  Opposite the patio, far across the lawn, was a planter bed, but since it was so far away and confined also by a low wall, the flowers in it were not recognizable from the patio. To my surprise, the lady told me that it held roses!  Her husband mentioned, almost in passing, that he would like to grow succulents.  Some trees were there, but they had been planted around the louter perimeter of the lawn so that they couldn’t throw any shade where it mattered most, which was on their hot south-west facing patio. 

“Hardscaping” elements such as patios, walk ways, fencing, arbors, boulders –  convey permanence and add structure.  Most of them don’t have to be maintained, except for some new coat of paint or occasional sweeping, depending on the material used. And they don’t demand watering, fertilization, pruning… So I suggest to incorporate them as much as possible into a design and let them “furnish” the garden, organize the space into areas of different use, provide separation as well as access, focal points, delineation and definition.

In the case of the before mentioned visitors, we found that a swing for adults, placed under a shade tree, would be lovely to have; I suggested to place it at the far end of the garden from where the family could see house and patio from a new perspective, and I drew its outlines on transparent paper taped over their sketch. And why not pull rose bed and succulents closer to the patio from where they could be seen?  Of course not into one flower bed, but in different areas that are perhaps even mounded up, separated by a walk way:  Gently curved mounds give movement to an otherwise flat plan, and the plants on them can be seen better, like on a painted canvas. And if your soil drains poorly, creating those mounds helps improve the drainage because you can mix the mounded soil to provide the drainage your plants need, such as many Mediterranean plants, California Natives and succulents, and even roses.

As for the lawn, we drew a much reduced kidney-shaped area that started at one end of the patio, wrapped around behind the rose bed and the succulent mound, and ended at the other end of the patio. This way it was still visible and easy to get to from the patio without dominating the foreground.  And to make all the different areas accessible, we discussed stepping stones and DG as possible material for the walkways, even coarse landscape mulch was considered.

Lastly we reviewed the possible locations of trees, and I pointed to my most favorite reference books on this subject:  Ornamental Trees for a Mediterranean Climate, the trees of San Diego, by Steve Brigham with book design and photographs by Don Walker, and the Sunset Western Garden Book. Here gardeners can research all their favorite choices before making the final selection; they can actually visit the trees shown in the tree book at their location!

Our time was up, and although we had not talked much about plants in detail, the family was happy (I suggested to look to the Water Conservation Garden’s displays for ideas).  Both husband and wife had information and tools in their hands that will make “playing” with their spaces, on paper first, a fun and exciting activity; selecting goals that are realistic and achievable with their budget and energy will now be a manageable task. And finally, armed with the proper reference books and resources that the Water Conservation Garden and other public gardens in San Diego County offer, they will be on their way to a garden that they can enjoy, and live in.

My “Fun-tainer” plants – as seen at the Del Mar Spring Home Garden Show 2011

March 23, 2011 By Christiane Holmquist

succulents and perennials in hypertufa containerAt the heart of my considerations for this container display was my desire to create a composition of beautiful yet tough plants that would delight their owners for a long time without being too fussy or difficult to replicate. They would need to tolerate exposure to drying winds, intense sun, month-long temperatures in the upper nineties or low hundreds and occasional light frost, periodic neglect (and no watering), and a lot of competition for space, both above the soil level as well as for the roots.  And they would have to like living in my hypertufa troughs (see my previous post), at least for the next 2 or even 4 seasons, to be “sustainable” (at least as far as a container-existence is concerned).

I already had a few suitable plants: Leucadendron discolor, Aeonium Sunburst, Firecracker Broom, Crown of Thorns, String of Pearls… These are all drought tolerant shrubs, perennials and succulents whose adaptation to prolonged container life on my deck in Ramona I had been admiring for a couple of years.  I only needed to find complementary plants that would offset or enhance their qualities and allow me to juxtapose textures, forms and colors.

Yellow Bird Pincushion Although my intended “pièce de résistance”, the Leucadendron discolor, had clearly proved that it can survive a container-existence (mine is now some 6 ft tall and 3 years old) it was too big for my trough.  I chose instead a close relative, the Pincushion Yellow Bird, Leucospermum cordifolia ‘Yellow Bird’ that drew lots of admiring comments at the fair.  This beautiful South African shrub is related to Proteas and reminds me of the flowers of thistles – without the bristles.  Sunset gives the growing zones as 15-17, H1 and  21-24. It grows to 4 ft tall and wide and can take several degrees of frost; the side buds will produce flowers even if the main flower buds freeze.  

The nodding Pincushion is the best species for cut flowers with blossom clusters that are about 4 inches across, borne at the branch tips.  The bloom peaks in late winter or early spring and can last for 6 months but can start earlier in mild winters.  It is supposedly difficult to grow because it needs perfect drainage, protection from drying winds but good air circulation.  It requires full sun, regular water only in the beginning until establishment (several months to a year depending on planting season) when it needs water only every 2 to 4 weeks.  Selections of this plant in other colors include ‘Flame Spike’ (salmon red) and ‘Red’ (orange red).

Sunburst Aeonium as container plant Because of the Yellow Bird’s gawky and gangly form I decided to place a “counter weight” next to it, and the appropriate one had to be the Sunburst Aeonium.  This succulent grows leaf rosettes at the branch tips that reach a foot across, to form plants that can be about 2 ft across and of about the same height.  The fleshy leaves have a delightful variegation that makes the plant very attractive.  It blooms after several years only and will then die, but the new  “pups” or side shoots will replace the mother plant.  With age, these plants become leggy but you can keep them bushy and encourage branching by cutting back branches several inches below rosettes.  These cuttings can then be used for easy propagation:  let them dry for a couple of days, then set in sandy soil kept barely moist until new grow emerges.

With its low watering requirements and equal sun tolerance it will make a good companion to the Yellow Bird.

Purple Heart Tradescantia Setcreasea pallida   Now, on the side of the Protea, I needed something softer, preferably in a complementary color, and draping over the edge of the container. For this I chose Setcreasea pallida (Tradescantia pallida ‘Purpurea’) or Purple Heart (also called Purple Queen):  This creeping plant has only moderate water requirements, is tolerant of some frost  that might kill the tops but recovery is fast in warm weather.  It will reach 1 to 1 ½ ft height and about 1 ft wide, and needs to be pinched back after bloom.  The stems tend to flop which makes a good container plant if combined with an upright ‘partner’.  (In parts of this county it can be unattractive in winter, but it seems well worth the try.)

Firecracker Broom or Coral Fountain as container plantIn the rear container one you can see the red and purple companions:  Crown of Thorns, Coral Fountain (also called Firecracker Broom), Geranium ‘Vancouver Sentenniel’ and Statice.  The Firecracker Broom, also aptly called Coral Fountain, is a good container plant:  Here it keeps a much neater and smaller form than in the ground where it can reach to 5 ft high and wide;  if the green, almost leafless stems of my container get too long they are easily shortened without loosing the graceful drooping form.  On my deck in Ramona it has continuously produced a profusion of bright red, narrowly tubular flowers since last year that attract hummingbirds. This shrub needs regular but small applications of fertilizer to keep blooming.  It tolerates partial shade or bright indirect light and needs only moderate to regular watering.

container succulent Crown of ThornsNext to it, producing an attractive contrast with its sturdy, upright form I planted Crown of Thorns Euphorbia milii.  It, too, hasn’t stopped flowering since I planted it in the previous container about 2 years ago.  It doesn’t seem to mind that I uprooted it from its previous home…  It’s a bit thorny but can be handled easily with leather gloves that will protect your hands also from the milky sap that can cause skin rashes and is toxic if ingested.

It also requires excellent drainage and has very low water demands. It grows 1 to 4 ft high and about 1 ½ ft wide which makes it an excellent upright narrow accent in a container.  Many varieties and hybrids of this one exist in colors of yellow, pink and orange.  In windy or frost-prone area it is best grown against a sheltered wall.  Salt tolerance makes it ideal for seaside plantings!  It tolerates partial shade or full sun, and as indoor plant it needs bright light.

All these plants are set into a fast-draining succulent soil mix.  The two troughs, displayed at the fair back to back, are now back at my house and adorn my front door and my deck.  I doubt that I will need to keep an eye on them for the last days of “winter” and a possible frost.  And for next winter I’ll keep an old bed sheet handy in case a strong frost is in the forecast.  From now on my main concern will be not to overwater, and to not forget to feed the plants occasionally, and to keep the ants from raising a colony of aphids on them.

 And if you need sources and would like to share your own container-stories with me, please let me know!

Essentials for the scented winter garden in Southern California

February 18, 2011 By Christiane Holmquist

When I got home last night in the rain, I took in the air in deep breaths:  Such a wonderful smell of wet soil and decaying leaves mixed with something sweet and flowery -  where was this powerful scent coming from?  So I put on my boots, took a flash light and went into the garden. 

California native spring blooming shrub Allen Chickering Sage California clevelandii  I got my face wet as I poked my nose into foliage and flowers of shrubs, perennials and succulents, and not far from my front door I found the first: A grouping of Cleveland Sages Salvia clevelandii that had just opened their buds. These California natives are known for their incredible fragrance, and for those who have never seen or smelled any, the description alone should make your mouth water:  This is an evergreen shrub of the mint family with a refined, rounded and arching form, to 3 to 5 ft tall and wide and wider for some cultivars.  It has wrinkled, toothed gray-green or dark green leaves that can be used in teas or as substitute for culinary sage and that are deliciously fragrant; a breeze blowing through your garden will take the sweet fragrance far. The flowers are an inch-long, pale lavender or violet-blue, arranged in whorls along the stems, and they are also fragrant.  To encourage re-bloom you will need to cut back these flower spikes back, but the shrub is also attractive with its dried flower spikes. 

This plant is so popular that several hybrids have been created:  Mine is the ‘Allen Chickering’ which gets  to 4 ft tall but spreads out to about 6 ft and sports pale purple flowers.  Check out also ‘Winifred Gilman’ with lavender-blue-purple flowers, or ‘Aromas’ with gray-green foliage and deep lavender flowers, ’Pozo Blue’ that is hardier than Alan Chickering’  (to 10 degrees F).  California native shrub Allen Chickering Sage blooming in winter with fragrant flowers

The Cleveland sages need sun (partial sun only in the hottest, driest regions), fast-draining soil, and are drought tolerant although they can tolerate occasional watering. There are differences in their cold tolerances that could be important for your location;  please check with the growers  below for the appropriate one. 

A little deeper in my garden the beam of my flashlight hit a tall lanky shrub whose buds were just opening, and I know it carries its name Mountain Lilac for a good reason: The flowers look like miniature Lilac clusters, and to me even their smell reminds me of true Lilac.  Mine is the hybrid ‘Ray Hartman’ which is the best known and most commonly grown of the bigger ceanothus hybrids that can reach 18 feet in height and width; its rose-colored buds open to display profuse clusters of sky blue flowers. drought tolerant evergreen California native Mountain Lilac shrub Ceanothus Ray Hartman

California’s Mediterranean climate supports 60 species and varieties of ceanothus, and the choices can be confusing. They grow in some of California’s harshest habitats, ranging from wind-buffeted coastal headlands to dry, exposed slopes at the edge of the Mojave Desert.  They come in various forms, from creeping to large shrubs and small trees, and their colors range from bluish whites and pale purples to deep Gentian blue and purple.  Most grow in areas that experience an extended summer drought; they tolerate a range of soil types but often are located on steep slopes in well-drained soils of low or marginal fertility.  Most then require excellent drainage, but some can also tolerate heavy soil and summer water.

Ceanothus have become popular shrubs in Europe, where cultivation of ceanothus species for horticultural purposes began as early as 1713!  Check with one of the growers mentioned below for the species that will perform best in your garden so that its growing conditions match or approach those found in its provenance.

Not far from my backdoor (and closer to the kitchen) I found Rosemary, a true Mediterranean whose name means “dew of the sea”, reminding us of the plant’s native habitat on seaside cliffs in the Mediterranean region.  This winter bloomer is not quite as fragrant as my sages but also definitely desirable.  The evergreen shrub is covered with narrow, resinous dark green leaves, and through winter and spring its fragrant pale blue to deep violet flowers are a magnet for bees and small birds looking for tiny spiders and insects in the tightly packed flowers (and perhaps also eat the petals).

fragrant winter bloomer Mediterranean shrub Rosemary Rosmarinus officinalisI love the ‘official’ Rosemary (Rosmarinus officinalis) with its upright habit and somewhat twisted branches reaching for the sky (height typically 4-6 ft and more, especially ‘Blue Spires’).  I use its stems for bouquets and the leaves for cooking; even the fragrant flowers are edible.  

As with many popular plants, there are too many cultivars and hybrids available to mention here.  Of great importance are the prostrate ground-hugging kinds whose heights range from 1 ft to 6 ft or more that are often used in erosion control or as groundcovers.      drought tolerant groundcover and slope stabilizer Prostrate Rosemary Rosmarinus prostratus

The toughness of Rosemary is admirable: It’s tolerant of moderate watering, sea-side conditions and blistering sun; I think it’s a must-have in the Mediterranean garden.  Although it can take alkaline soil if given a moderate feeding from time to time, good drainage is essential; you can lighten heavy soil with plenty of organic matter.  Their cold-hardiness varies depending on selection.

All of these specimens are excellent examples of low water-use, low maintenance, beneficial plants that I love to use in water-wise landscape designs; I think they belong to the category of plants that are indispensible when the design wants to be ‘sustainable’, and with these attributes and their famous fragrance who could resist?

Olives in January – Another California Winter Story

January 10, 2011 By Christiane Holmquist

drought-tolerant-olive-tree-tipsHaving my daughter home at Christmas is always a delight as we enjoy as much time in the sun as we can, while her home town is buried by several feet of snow.   This last holiday, as we were enjoying some gardening chores together my daughter commented on the heavy olive crop that was still on the tree.  I guess it was the appetite for another chicken baked with black olives, rosemary and lemon peel (one of our favorite recipes) that encouraged us to get serious about harvesting our olives before rodents, birds or insects would get them.

drought-tolerant-olive-tree-tipsPlacing the ladder under the canopy to get to the branches for hand-picking was difficult because of the many ornamentals planted in the dappled shade of the tree.  (This drought tolerant, attractive tree with silvery-green foliage is a wonderful addition to the drought tolerant, Mediterranean garden, and many un-thirsty plants enjoy the dappled shade that it provides.)

Most of the other olives had to be gotten down without help of the ladder, so we tried raking or knocking them off with a long pole and catching them in a tarp that my daughter and I held up. All needed to be done carefully to prevent injuries to the branches because this could have invited “Olive Knot”, a bacterial infestation resulting in galls developing at the branch that will cause die back.  (To protect from Olive Knot requires a couple of copper sprays each year, one in the fall following harvest and one in the early spring.)

We filled a few buckets, picking out the mushy or half eaten ones of which there were a few.  This fruit has been enjoyed for thousands of years in the Mediterranean area (where it is still grown), so there is a multitude of curing recipes out there.  We prefer the salty dry ones like the black, pungent French Nyons olives, so after washing them we are curing them now with salt.  The curing is needed to remove the bitter glucosides (“Oleuropein”)  that account for the horrible taste (which is a pity – they look so appetizing already uncured!)  Other methods are water curing, brine curing and lye treatments  (See “Safe Methods for Home Picking” , a publication by the University of California, Div. of Agriculture and Natural Resources, at http://anrcatalog.ucdavis.edu/pdf/8267.pdf )

To try dry-salt-cure olives, use a pillow-case, for which you have made a drawstring top. Mix the olives with their own weight in non iodized table salt, pickling salt, or rock salt.  Pour them into the pillowcase and cover with more salt. Hang the pillow case in a place where the juice that will drop from it will not stain -  perhaps in a tree?  Stir them once a week for 4 weeks or until they have lost their bitterness.  When they are no longer terribly bitter, rinse in water and allow to dry overnight.  Then pack them in oil until you are ready to consume them.  (From “Lost Arts, A Cook’s guide to making vinegar, curing olives, crafting fresh goat cheese and simple mustards” by Lynn Alley, Ten Speed Press).

It was particularly interesting to learn from the Olive Grower’s Council of California in Visalia that some small olive oil presses may actually still cold press. However, most modern olive oil equipment warms (not heats) the paste to allow better release of the oil from the olive flesh.

Here some more background info that Mr. Adin Hester of the Olive Grower’s Council shared with me:  Table olives are an important economic crop in California. Major producing counties include Tulare, Fresno, Madera, Glenn, Tehama and Butte. LA County/San Fernando Valley at one time was a major producer of olives for oil and table use. (About the same historical time,  Butte County was also a major table and oil producer.)
Now the San Joaquin and Sacramento Valley are the major producers.

The 2010 crop produced a record setting 164,984 tons. About 5% was left on the trees because of small size and freeze damage in late November. This year’s harvest was one month later than normal. The industry generally begins table olive harvest in mid-September and finishes by November first.

Olive oil harvest begins in late October to early November and generally finishes by the end of December.  The later harvest, the greater the risk of freeze damaged olives. Frozen olives produce an unacceptable oil.

Today two major varieties of table olives are grown in California:  Manzanillo (80%), and Sevillano (the big green olive that gets fermented and stuffed with almonds) (20%).  There are still minimal acres of Mission, Barouni and Ascolano table olives grown in California. Even a few acres of  Kalamata olives are found in the state.

Olive tree culture:

Cold hardy to 15 degree F / -9 degrees C, it thrives in areas with hot, dry summers but also perform adequately in coastal areas.

This very ornamental willow-like tree with its soft silvery-green foliage grows slowly, typically to 25-30 ft high and as wide.  Young ones put on height fairly fast.  It is a more of shrubby tree so training begins early in life, where for a single trunk side branches are shortened and later pruned away below the point where you want branching to begin. The old-timers suggest letting the seedling grow freely for the first 3 – 4 years, then prune for shape.  The tree can be also trained into a multi-trunked form; for this, stake lower branches or basal suckers to continue growth at desired angles. It likes well drained soil but also grows in deep, rich soil, or stony soil with little fertilizer.

Pruning is important to maintain a champagne-flute shape of the foliage – if you are interested in a healthy tree and a good crop.  The tree is self pollinated, and opening the canopy will enhance air flow and good fruit setting.  Pruning should be done after harvest and when the danger of frost is over, which suggests early spring as the best time.  The new wood the tree produces during the g rowing season is where the buds will form to produce the following year’s crop.

The Olive tree should not be topped. An exception to this rule is the use of the olive as a hedge. It will form a dense, attractive hedge if topped and trimmed.

Water: It is drought tolerant; however, to produce a crop they need moisture consistently. Spain has over 5.5 million acres, most of which are dry-land farmed.  This results in not much production per tree or per acre, but the acreage multiplier still gives them the recognition of being the largest olive producing country in the world.
