Hedges & Living Fences

When I visited eastern Poland many years ago each house and garden was enclosed with a fence or hedge of some sort. Some fences were wood, some stone, some ornamental iron and some were living fences that divided properties. I thought the living hedges were the most beautiful and neighborly. Whether you need to screen a water tank or noisy road or the neighbor?s second story window there are lots of choices. Fall planting season is still going strong.

Many people only think of plants that remain evergreen when they need screening. However, if you use one-third deciduous plants to two-thirds evergreens they will weave together and you won’t be able to tell where one leaves off and another begins. This makes mature hedges secure borders, especially if you throw a few barberries or other prickly plant into the mix. You’ll also get seasonal interest with fall color and berries for wildlife.

Azara microphylla

Narrow spaces can be challenging when you need to screen the house next door. There?s not room for a big, evergreen tree or hedge to solve the problem. One way is to use plants that can be espaliered against a fence or trellis. Some plants like azara microphylla naturally grow flat without much coaxing on your part. This small dainty tree is fast growing and reaches 15-25 ft tall. The yellow flower clusters will fill your garden with the scent of white chocolate in late winter. They are ideal between structures. I?ve used the variegated version to screen a shower and it?s working great.

Variegated Mint Bush

Variegated Mint Bush is another shrub to consider for a living hedge. Creating pleasing plant combinations is a big part of gardening and this one would look great alongside a Fringe Flower of either color. Allow each plant to interweave and grow together. The Mint Bush will grow 4-6 feet tall and 3-5 feet wide. The foliage smells very strongly like mint so deer avoid this shrub, too.

Small trees that make a good screen are purple hopseed, and leptospermum ?Dark Shadows?. Both have beautiful burgundy foliage. California natives that can be espaliered against a fence include Santa Cruz Island ironwood, Western redbud, mountain mahogany, toyon, pink flowering currant, Oregon grape and spicebush.

Pacific Wax Myrtle

If you have a wider space to grow screening plants, one of my favorites is Pacific wax myrtle. This California native grows quickly to 30 ft tall with glossy, rich forest green leaves. Its dense branches make a nice visual and noise screen for just about anything or anybody. Best of all the fragrant waxy purplish brown fruits attract many kinds of birds.

osmanthus heterophyllus

California coffeeberry grows 6-8 feet tall and gets by with very little summer water once established. Birds love the berries. I also like osmanthus fragrans for a screen with its sweet scent and pittosporum ?Marjorie Channon? or ?Silver Sheen? for their showy variegated foliage. Email me and I?ll give you even more suggestions.

Provide the best growing environment for the fastest results. By this I mean amending the soil at planting time if your soil is not very fertile. Cover the soil with mulch and fertilize with compost or organic fertilizer. Water deeply when needed especially during the first three years when young plants put on a lot of growth.

Autumnal Equinox in the Garden

The autumnal equinox happens on Saturday, September 22nd this year. It’s the official start of fall when the sun crosses the celestial equator and moves southward. The earth’s axis of rotation is perpendicular to the line connecting the centers of the earth and the sun on this day. Many people believe that the earth experiences 12 hours each of day and night on the equinox. However, this is not exactly the case.

During the equinox, the length is nearly equal but not entirely because the day is slightly longer in places that are further away from the equator ( like where we live ). Also the sun takes longer to rise and set in these locations as it does not set straight down but in a horizontal direction.

ceanothus ‘Heart’s Desire’

With the changing of the season, take advantage of fall planting weather by looking at what’s covering your ground. Be it the small lawn for the kids to play on, ground cover to keep the weeds at bay or erosion control to keep the hillside intact, this is an excellent time to plan for winter.

Let’s start with the lawn. If you still need a space for recreation, this is a good time to reseed those bare spots. Also to keep the lawn healthy by removing underlying thatch with a thatching rake. Then aerate the lawn by poking holes in the sod and fertilize with a complete lawn fertilizer like an organic all-purpose. Your lawn needs the phosphorus in the fall to encourage deep, strong roots for the winter.

If the kids are grown and no one is using that lawn, why not rip out the water guzzling grass and replace it with a walk-on groundcover? There are many to choose from like dymondia, lippia, potentilla, duchesnea strawberry or any of the kinds of thyme.

Living ground covers add beauty to the garden while holding the soil in place and preventing erosion. They contribute to soil health by encouraging microorganisms. A garden wouldn?t thrive as well without groundcovers.

One of my favorites is Elfin thyme. It doesn’t need mowing, edging or fertilizing or much irrigation. You can walk on it and it stays green all winter, shading into bronze tones when the weather cools. It even blooms in midsummer for several weeks. Note that bees are attracted to it as with all of the ground covers in the thyme family at this time.

kurapia

Another favorite that I have in my own garden is kurapia. It?s deep rooted, doesn?t require much water, is compact and low maintenance. It?s been bred to have sterile seeds. This is a good groundcover if pollination of nearby fruit trees is needed or you want to encourage bees to your garden for pollination. If bees are an issue kurapia can be mowed to cut off the blooms.

There are also Ca. native and prairie meadow grasses that you can walk on. They need little irrigation and even less mowing. Some can be planted from seed, others from plugs or sod. Good choices include Idaho, California and red fescue, carex pansa, June grass and Hall’s bentgrass.

grevillea lanigera ‘Mt Tamboritha’

If you don’t need to walk on your groundcover, low-growing native shrubs that are good groundcovers are baccharis, ceanothus maritimus, ?Anchor Bay or ?Heart?s Desire?, manzanita, creeping snowberry, creeping mahonia, salvia ?Bee?s Bliss? and ribes viburnifolium. Mediterranean ground covers like cistus salviifolius, grevillea lanigera, rosemany prostratus, rubus pentalabous are also good low-water choices.

It’s time to enjoy fall weather and cover that ground before winter.

Fall Planting California Natives

The chill is in the air. At least as I write this. Next week it could return to summer-like weather but for now I?m thinking of what plants I want to add to my garden this fall planting season. California native plants are well suited to planting at this time of year and acclimating to their new homes without much stress. Here are some ideas to get you started.

matilija poppy

By planting from mid-September through mid-November, roots of all plants have a chance to grow during autumn and most of the winter as well without having to supply nourishment to the leafy portion of the plant. Roots of deciduous plants still grow even after plants drop their foliage as long as the ground temperature is above 50 degrees. Cooler day and night temperatures slowly harden off the top of the plant to prepare for the cold days of winter.

Another reason that fall is the no-fail planting season is because plants put in the ground in fall need less water to establish. The plants themselves use less water since photosynthesis is slowed by shorter days even if it’s occasionally hot. Evaporation rates slow down also during fall so moisture in the soil lasts longer as well. Sometimes we get lucky with fall and winter rains perfectly spaced so the ground never completely dries out. I?ve heard rumblings about an El Nino winter but you know how that sometimes goes here in our coastal area.

ribes sanguineum ‘King Edward VII’

Plants that thrive in dry, shady spots benefit especially from fall planting as they need established root systems before next years dry season. Dry shade sometimes occurs in places beyond the reach of the hose but also under native oaks. To protect their health, it’s a requirement that plants underneath thrive with little or no summer irrigation.

Plants of proven success under these conditions include native currants and gooseberry. Ribes sanguinem (red flowering currant) is a show stopper capable of controlling erosion. In the spring the long, flower clusters of this deciduous shrub will dominate your garden. There are many selections of this plant to choose from so if the huge white flowers appeal to you ‘White Icicle’ will be beautiful in your landscape. ?Barrie Coate? and ‘King Edward VII’ have spectacular deep red flower clusters and ??Spring Showers?? has 8″ long pink ones. Grow in full sun to partial shade. This California native requires little water once established and is a valuable nectar source for hummingbirds.

Some other good California native shrubs for erosion control are western redbud, mountain mahogany, western mock orange, lemonade berry, toyon, snowberry, matilija poppy and western elderberry. ribes viburnifolium, creeping mahonia and snowberry, baccharis, ceanothus maritimus and Anchor Bay are good groundcover selections.

Smaller natives that put down deep roots are yarrow, coast aster, California fuchsia, wild grape, mimulus, buckwheat, wild rose, sage and salvia.

Bush poppy (dendromecon rigida) is another native found right here in our area and needs no irrigation at all once established. Beautiful bright yellow, poppy-like flowers cover the plant in spring. They can be propagated from cuttings taken in summer and are pest and disease free.

Remember when setting plants on a steep slope to arrange them in staggered rows. Make an individual terrace for each plant and create a basin or low spot behind each one ( not around the stem ) to catch water. Set the crowns of the plants high so they won’t become saturated and rot after watering and make sure mulch does not build up around the stem.
