Express your Garden Style with Paths and Good Design

OLYMPUS DIGITAL CAMERAI get a lot of calls from homeowners who need help seeing their property through new eyes. Maybe they’ve lived there for a long time but the landscaping needs an update. Or maybe they’re just moving in and the landscaping has been neglected for a while. Whatever the reason, there are techniques I use to bring out the best in a space. This is the time of year when all things seem possible. Take a few moments to really look at your garden. Look at the view from inside the windows and from the driveway as you enter. Then imagine all it could be with some simple changes.

The elements of garden design, like arrangement of paths, planting beds and open spaces, shape your garden.  Have you ever noticed how your eye is drawn along a path through the garden?  The plantings along the sides serve to frame but it’s the style of the path itself that enhances your experience in the garden.

The materials you choose for a path determine how fast or slow your walk will be.  A casual path OLYMPUS DIGITAL CAMERAof gravel or bark chips lends itself to slow meandering around bends in the path.  Flagstone pavers set in sand with spaces left between for low growing ground covers are good choices for both major access walks and smaller paths.    Be sure to space the stones no further than a comfortable stride apart.  Other materials that make good paths are brick, cobbles and pressure-treated lumber.

A curved line or offset sections of paving slows movement inviting you to notice the surroundings.  Curves should look as if they are supposed to be there.  Place a large plant, rock or sculptural feature at a turning point so that you must walk around the object.  Remember a lightly curved path makes a nice entrance walk or a stroll through the garden but stick with straight lines for a path to take out the trash or get fire wood.

OLYMPUS DIGITAL CAMERAWalkways should be designed for comfort and accessibility.  A walk that leads to your front door should be 4-5 feet wide, enough to accommodate 2 people walking in opposite directions at the same time.  Smaller paths, 24″ wide, are OK for one person to stroll through the garden further out from exits and entrances.

If your garden is small, a tapering path edged with curving flower beds will seem to converge on the horizon, giving the illusion of depth and distance.  Plantings of grasses in the beds will create a sense of movement.

You can separate plants and people by designing seating along the walkways.  A good spot to place winding pathseating is at a fork in the path or where two types of paving meet another.  Any object you can comfortably sit on is a possibility.  Besides wood or ornamental iron benches, rocks, tree stumps, seat walls and planters can also double as seating.
.
The best gardens include focal points other than plants and trees.  The art you place in your garden reflects your style as much as the art you have in your home. A ceramic pot placed as a focal point can add drama to your space.  A metal sculpture or wall hanging can do the same.  The great thing about making a garden is that you don’t have to do it all at once.  And gardens are easy to alter as your ideas change.  A garden is never done.

Creating interest outside a window depends not only on plant choices but also simple design solutions. Keep the garden simple and restful. Editing some of the plants will make the garden lower maintenance, too. Plants that have overgrown the space need constant pruning. Move them to a better spot.

Limit the number of elements in the garden. Rather than trying to include everything in the garden try for a unified look with the fewest number of things. Make each one count.  Place objects to define a space. This doesn’t mean creating separate garden rooms necessarily but more like a set of boulders to signify distinct parts of the garden.

Another tip that makes an area more restful visually is to limit your plant palette. Plants that you can see through make a space seem larger. Some plants like Japanese maple, nandina and dogwood are naturally airy while other plants like camellia can be pruned for openness. Low growing, mounding ground covers help unify the garden. Plant soothing greenery for year round appeal with seasonal color from perennials and shrubs.

With a little planning your landscaping can express your own style.

Smart Irrigation

dry_river_bed2.1280Several years ago I was invited to tour a beautiful garden in the hills above Scott Valley High School. Robby Frank was more than eager to share his techniques for gardening in deer country. He was also in a personal battle with gophers and moles and I affectionately bestowed upon him the title, serial mole killer. I am happy to report that Robby has won the war on all fronts. His garden is more lush than ever and with that comes the ongoing dilemma of saving water in the landscape especially in this time of drought.  He solved the problem by installing a Smart Irrigation Controller and has been so pleased with the results he’s on a Smart Irrigation crusade to educate fellow gardeners. Here’s his story.

We all know mulching is one of the ways to conserve water in the landscape. Robby has long been an advocate of composting and regularly renews the mulch in his garden. He even calls himself  “Mr Mulch”. He has permeable paths and a dry river bed that allow rainwater runoff to soak into the soil slowly. He keeps his plants pruned in a naturalistic manner because “smaller plants use less water'”. But all this wasn’t enough. His 3 “dumb timers”, as he calls them, were using too much water. That’s when he started researching weather based smart irrigation timers.
drought_tolerant_plantings.1024
“To me it seemed like an easy way to conserve water and it’s better for the plants as well”, Robby said. “It will increase the irrigation times if the weather is hotter and dryer than usual,  decrease if it’s colder and turn itself off if it rains”. Robby was already familiar with the Rainbird brand of controllers although there are many other companies that offer them. That’s why he eventually chose the “Simple to Set” Smart Indoor/Outdoor Irrigation timer or Rainbird SST 1200s.
Rainbird_Smart_Irrigation_Controller
Scotts Valley Water District offers a Landscape Rebate program for weather based irrigation controllers and has a list of acceptable models on their website. Robby paid $165 online for his controller as he couldn’t find a local store that stocked them. Since then he has convinced the local Ace Hardware to carry them.  It replaced his 3 old controllers and he received a rebate from the SV water district for $100. San Lorenzo Water District has a similar rebate program.

To qualify for the credit, he arranged for someone to come to his house to take pictures of his old watering_schedule.1280controllers. After installation they came again to see the new controller and he completed the necessary paperwork. The rebate credit which can vary from $75-$100 doesn’t cover the cost of the controller or installation labor and is determined by the type of controller installed. You can’t go wrong with saving water, money and getting a rebate, too.

The best part of the new system is how it saves water and is better for the plants.  The controller is never turned off. You enter your zip code and the watering schedule you prefer and the controller adjust the amount of water either up or down as needed. For instance, when it was dry before the December freeze, the controller watered his landscape at 20-30% of normal so the plants were not totally dry during that week and were better able to stand the extended freezing temps.

Likewise, the sensor can trigger the controller to irrigate 130% of normal if it’s exceedingly hot and dry. The controller, also called a timer, comes with 10 years of historical weather data for any US ZIP code and includes a rain and temperature sensor.

Robby showed me how amazingly easy it is to set up and program the controller. It’s called the Simple to Set irrigation timer and I agree. Because he propagates most of his succulents himself from cuttings, it’s easy for him to add a bit of extra irrigation on a one-time or sort term basis until they become established. He couldn’t do that with his old timer. It had to water the whole area on a valve the same. Now he has 12 zones that he easily programmed for just the right amount of water whether it’s several times a week or once a month.

Robby Frank is on a crusade to save water and Smart Irrigation is the way to do it. If you want to read more about how he battles deer and moles you can access the story I previously wrote about him on my blog by searching Serial Mole Killer. He would love to find other local like-minded gardeners to share stories.

Winter Flowers that Use Less Water

In our neck of the woods we could change the iconic saying inscribed on a New York Post Office that reads  “Neither snow now rain nor heat nor gloom of night…”  to “neither drought nor freeze nor wind can stay the coming of spring”.  Spring is everywhere whether we are ready or not. The birds are announcing their presence in anticipation of the breeding season. Early blooming Saucer magnolia are covered with huge pink and purplish flowers. Daffodils are already opening.

There’s not a more important time of the year to have flowering plants in the garden. The restorative benefits of growing things is astonishing. They soothe the soul and refresh the spirit. Here are some plants I like to plant in my own garden as well as recommend to others.
clematis_armandii4
Scented flowers are nature’s way of rewarding pollinators with nectar and people with smiles. One such plant blooming now is the vine, Evergreen clematis or clematis armandii.  Most books say it can thrive on occasional summer water, defined as every 10-14 days during the dry months, but I’ve seen established vines bloom in spots that receive no supplemental summer water at all. The vanilla fragrance of the creamy white, star-shaped flower clusters is fabulous, their heady scent filling the air. This vigorous, cold hardy, evergreen vine has foliage that emerges bronze colored and then matures to a glossy dark green. It’s a great choice for filling a large space.

We’ve had a little rain but I still think it’s a good idea to concentrate on plants that need only daphne_odora_Aureomarginataoccasional water during the summer months or drought tolerant species that can thrive with water 1x per month. A good plant choice that fits the bill is Variegated Winter Daphne. Daphne odora ‘Aureomarginata’ is evergreen and wonderfully fragrant. This deer tolerant shrub is good looking year round and does well under the shade of small trees. Although many daphnes are tricky to grow, this one is adaptable and easy to please. During the summer water it as infrequently as the plant will allow. Little or no water in summer will reward you with clusters of fragrant purple flowers that start opening at this time of year.  Cut them to bring inside with hellebore and euphorbia for a pretty bouquet.

For May fragrant flowers try daphne burkwoodii ‘Carol Mackie’ which is also easy to grow and requires only occasional water as does daphne transatlantic ‘Summer ‘Ice’. Summer Ice produces sweetly scented flowers for an extraordinarily long time. Flowering begins in early April and can continue as late as November.

helleborusHelleborus is one tough plant. Also called Lenten Rose this extremely cold hardy, deer tolerant perennial blooms in the dead of winter. It looks especially good planted under winter and early spring flowering deciduous shrubs like witch hazel, viburnum, red or yellow twig dogwoods. Cut foliage to the ground in December so that flowers are displayed unobstructed.

Other drought tolerant plants in this family include the Corsican hellebore which is the largest of the hellebores. Creamy, pale green flowers float above leathery, evergreen foliage. This hellebore is tough and long lived if left undisturbed. It will grow in sun or shade and prefers a well drained or sandy soil but will tolerate clay if drainage is good. Once established it is fully drought tolerant.

Helleborus foetidus is also called Stinking hellebore but don’t let the name fool you. Only if you crush the leaves or stems do you get a strong chlorophyll smell which makes the plant unattractive to deer. The flowers last throughout the winter. This unique plant is the only plant discovered to date that uses yeast to produce heat.

Rounding out the short list of low water use, winter flowering plants are vine maple, berberis thunbergerii, euphorbia characias wulfenii, iris pallida, ribes sanguineum, huckleberry, forsythia, witchazel, azara microphylla,  western wild ginger and rosemary.

What to do in the Garden in February

flowering_plum.1024The unusually warm January weather has made the early flowering trees and shrubs bloom even earlier this year. Actually it’s not so unusual for us to have a warm streak around here in January. What is unusual is the prolonged dry and stable conditions we have encountered. The high pressure system that blocks our usual winter rains does not usually last more than 2-3 weeks even in the heart of the rainy season. The persistent ridge has not behaved in a typical manner. We can only hope the ridge breaks down in the next few months and brings us more than a smattering of rain here and there.  What should a gardener be doing in February?

Prune fruit trees. Smother overwintering eggs and insects by spraying with horticultural oil. quince_red.1280Combine your spray with lime-sulfur ( except on apricot trees ) or copper soap to kill fungal disease spores like the ones that cause peach-leaf curl. Spinosad has also been shown to supress fungal diseases. Do this when the buds swell but before they open. Do not spray 36 hours before rain in predicted. Be sure to spray the ground around each tree.

I recommend keeping winter pruning to a minimum and prune again in the summer time. Winter pruning is invigorating to fruit trees and there will be excessive vertical rebound growth, the witch’s broom-like riot of growth that emerges after a tree is given a haircut. Such growth is often dense and doesn’t bear much. A lot of the tree’s stored energy issued to produce all these unwanted branches, leaving much less for the production of fruit.

quince_red-closeup.1280Due to our unusual weather some low-chill fruit tree varieties like Fuji apples, many apricots, peaches, nectarines and pears such as Comice and Seckel, might break bud and flower earlier because of the winter freeze and then warm weather. Plants that flower prematurely risk losing those flowers if night temps plunge but the long-term health of the plant probably won’t be affected.

Strawberries are oblivious to the weather. Blackberries and some raspberries are another story. Like some fruit trees, their chilling requirements may have already been met, their buds are swelling and they’re ready to take off. A rapid chill could freeze the buds and the canes might begin to die from the top down. But even if the entire cane dies, healthy new canes will emerge in spring. The early summer berry crop could be lost but fall berries will be fine.

Prune woody shrubs  To stimulate lush new growth on plants like Mexican bush sage and artemisia cut them down to within a few inches of the ground. Don’t use this approach on lavender or ceanothus, though. Lightly prune them after blooming and don’t cut back to bare wood inside the plant.  Prune fuchsias back by a third and remove dead, crossing branches and interior twiggy growth. Container fuchsias can be cut back to the pot rim. You won’t be able to know for sure, until perhaps early summer, if the freeze killed plants like Coprosma, Echium, Tibouchina or lantana so be patient.

Cut back hydrangeas stems that bloomed last year if you haven’t already done so and apply a soil acidifier if you want the flowers blue. Coffee grounds, pine needles, peat moss and cottonseed meal are kind to your soil and the beneficial soil microorganisms.

Don’t prune spring flowering shrubs and trees like lilacs, flowering cherries, plums and crabapples,  rhododendrons, azaleas, camellias, weigela or spirea until after they flower.  Cut some branches during flowering to bring in for bouquets.

Prune roses and rake up any debris beneath the plant to eliminate overwintering fungal spores. Remove any old leaves that still cling to the plant. Spray the stems and bare ground with a combination organic horticultural oil and a dormant spray.

Prune established perennials later in the month if you might get frost that could damage new foliage. Giving your maiden hair ferns a haircut now allows the new growth to come out fresh. Prune winter damaged fronds from your other ferns.

Divide perennials before new growth starts. Agapanthus, asters, coreopsis, daylilies, shasta daisy and liriope are plants that tend to become overcrowded and benefit from dividing.

Mother Nature knows how to adjust to changes in the weather- slowing down when it’s really cold and catching up when it’s mild.

Drought Tolerant Gardening

arctostaphylos.1280Last fall I wrote about the predictions for winter rains in our area. The Farmer’s Almanac predicted our “winter will be much rainier and cooler than normal”. Weather bloggers online posted an impressive number of charts and figures predicting “a general dry trend”. NOAA said we had an equal chance of precipitation totals going either way.

Even my favorite predictor, the Sandhill crane, who started it’s annual migration to the San Joaquin Valley several weeks earlier this year, seems to have gotten it wrong. The timing of their migration has been a good predictor of both wet and dry winters. This year the early migration predicted an early winter with plenty of rain and snow.

Every snowboarder, gardener and nature lover knows we are in a great drought that started last winter. Information about the California drought is all over the news. We are sure to get a few storms in the coming months but there will be no “Miracle March” from what I see and hear from the experts at NOAA and NASA. This extreme weather event will bring voluntary or possibly mandatory water rationing. What can we do to make the most of the water allotted to the garden and not let expensive mature landscaping die unnecessarily? How can you make your garden more drought tolerant?

1) Group plants in your garden according to their water needs. Some can survive on rainfall bush_poppy.1600alone after their second or third season while the perennial beds, vegetable garden and fruit trees will require a different schedule. Late winter or early spring is a good time to transplant those plants that use more or less water than their neighbors.

2) Examine your irrigation system and watering plan for efficiency and minimal waste. Watering in the early morning is the most efficient way to maximize absorption whether you water by drip system, sprinkler, soaker hose or by hand. The water soaks deep in the soil without risk of evaporation. It bolsters the plant for the day and has dried from leaves by evening reducing the risk for foliar diseases like mildew. Plant roots are also more receptive to watering in the morning. Water slowly, deeply and infrequently so there is no runoff. This also allows plants to grow deep roots that can go longer between waterings.

lupine_silver.16003) Using vegetation or mulches to cover bare soil is a key ingredient to slow down runoff. Maximize what soaks into the ground.  Mulches are a good choice for areas with less than 33% slope, Vegetation works well on areas with less than a 50% slope. Mulch can be organic-such bark chips, straw or grass clippings or inorganic gravel or cobbles. All protect soil from erosion and conserve soil moisture. Organic mulches keep plant roots cool, encourage earthworms and other beneficial organisms and prevent weed growth. Your plan should be to slow, spread and sink water back into the ground whether it be from rainfall or irrigation.

Of all the types of mulches, recent studies have shown that ramial bark chips are one of the best mulches to improve soil health. Ramial chips are those from trees and brush, from branches up to about 4″ in diameter with or without leaves. Deciduous hardwood is best but all chips are good These chips contain a high percentage of thin young bark and young wood. This is what makes them so valuable to the garden. Young wood is the trees factory for producing protein, glucose, fructose, lignin and polysaccharides. It’s an important source of nutrients for living things at all levels according to a study by 2 soil scientists, G.  Lemieux and R.A. Lapointe.  You can obtain these kind of chips free from tree trimming companies like Davey Tree who is probably working nearby chipping roadside brush for PG&E.

Water makes up 90-98% of every plant we grow. It’s needed for photosynthesis, as well as reproduction and defense against pests. Improving your soil’s ability to absorb and hold water should be a priority when you’re out in the garden. Help ensure the health or your trees and garden by following these steps.
