February in the Garden

I?m waiting patiently for the buds on my pink flowering currant to start lengthening a bit more. I wasn’t counting on the recent snow and cold snap but the buds are showing color and are doing fine. Although still small at this stage I?ve assured my hummingbird population that they?re on their way. When I was out pruning last week I didn?t touch this plant otherwise I?d have cut off all those potential flower clusters loaded with nectar. This is what I did do in my garden.

To stimulate new growth I trimmed woody evergreen shrubs like abelia and loropetalum. The Mexican bush sage and artemisia were cut to within a few inches of the ground. I don’t use this approach on lavender or ceanothus, though. Lightly prune those after blooming later in the season and don’t cut back to bare wood inside the plant.

Between rain storms I?ll prune my fuchsias back by a third and remove dead, crossing branches and interior twiggy growth. The hanging fuchsias will be cut back to the pot rim. Fuchsias bloom on new wood so even if your plants didn?t lose all their leaves cut them back.

I cut back all the hydrangeas stems that bloomed last year and will apply a soil acidifier soon as I want the flowers as blue as I can get. Although aluminum sulfate is the traditional favorite for quickly acidifying soil it?s not as kind to beneficial soil microorganisms. Coffee grounds, pine needles, peat moss and cottonseed meal are better for your soil.

Don’t prune spring flowering shrubs like lilac, weigela and spirea or flowering trees such as cherry, plum and crabapple now. These and plants with buds like rhododendron, azalea and camellia should be pruned after they flower. You can cut some branches while they are blooming to bring into the house for bouquets.

Even if you have already pruned your roses be sure to remove old leaves still clinging to the plant. Those will most likely develop fungal spots and diseases later if you don?t. Rake up any debris beneath the plant and discard to eliminate overwintering fungus spores

Roses are super forgiving and you can trim them up again using the following guidelines. The goal is to produce lots of roses not just a few of exhibition size. Aim for a vase-shaped bush with an open center.

Prune old garden roses that bloom once in the spring after flowering. Climbing roses require little pruning. Cut out extra stems if there are too many and also cut back long established canes to about the place where they are slightly thicker than a pencil. Then cut each side stem down to several inches. This will cause the cane to flower along its complete length for a beautiful spring display.

Wait to prune back perennials that may have their new foliage damaged in a late frost. Same goes for shrubs that might have gotten hit by frost. That damaged foliage can protect the plant from further frost damage. Mid-March is the estimated date of hard frost in our area or at least it used to be. We gardeners are always betting Mother Nature will go our way and our efforts will not have gone in vain.

Prune fruit, nut, shade trees and deciduous vines like clematis.

Cut back ornamental grasses if you live where you rarely get frost. I?m pruning California fuchsia, salvia ?Bee?s Bliss? and hummingbird sage now. They look okay but I want the encourage new, compact growth.

And now I?m making myself a cup of tea and watching the chipmunk action in my garden. All of nature is getting ready for spring.

Dog Days of Summer, perennials, roses

The Dog Days of Summer

They?re called the Dog Days of summer. You know those sultry days with the hottest summer temperatures. The Romans associated the hot weather between July 24th and August 24th with the star Sirius which they considered to be the ?Dog Star? because it?s the brightest star in the constellation Canis Major (Large Dog). The Old Farmer?s Almanac uses slightly different dates but the Dog Days of summer are definitely here.

Dahlia- a repeat bloomer

Recently I moved to Bonny Doon where gardening in the hot, sandy soil is very different than the shady clay I was used to. One thing I?ve noticed is the existing drip system has not been modified to allow for the growth of the plants. The emitters which were originally placed at the base of each plant are not even close to covering the current size of the root zone. The crown of the plant is getting overwatered with each cycle but the rest of the plant is bone dry. Time to add more emitters maybe even downsizing to half gallon ones and moving them away from the middle of the plant. No sense wasting water that?s not doing the plant much good.

As summer rolls along you may become more aware of the different microclimates in your garden. With the drier and hotter weather this year some of your plants that used to get along just fine might be showing signs of stress. Taking note of these changes in the performance of your plants is what makes for a more successful landscape. When the weather cools towards the end of September you will want to move or eliminate those plants that aren?t thriving. Be sure to keep a thick layer of mulch on the soil around your plants to conserve that precious water you do allocate to each of your irrigation zones.

Roses with Baby’s Breath- deadhead regularly

The dog days of summer may be affecting our garden but it doesn?t have to stop us from being out in the garden. . The joy of gardening can take many forms including adding a wind chime, bird feeder or bird bath. Groom plants that need some cleanup. Many perennials benefit from a little haircut at this time of year to extend their blooming into the fall season. Santa Barbara daisies fall into this category. Lavenders will keep their compact shape by pruning a third of their branches now. This forces new growth in the center so the plant doesn?t get woody.

Deadhead flowering annuals and perennials as often as you can. Annuals like marigolds, petunias, zinnia and cosmos will stop blooming if you allow them to go to seed. The same is true of repeat blooming perennials like dahlia, scabiosa and lantana.

These plants know they’re on this earth to reproduce. If they get a chance to set seed, the show’s over- they’ve raised their family. Try to remove fading flowers regularly and you’ll be amply rewarded.

Strike it Rich rose

Fertilize shrubs lightly one last time in August or early September. All shrubs, especially broad-leaved evergreens such as rhododendron, pieris, camellia and lilac need to calm down, stop growing and harden off to get ready for the winter cold. Some plants have already set next year’s buds.

Roses will appreciate a bit of fertilizer now, encouraging them to bloom another round in September and October. To keep them blooming make a habit of pinching and pruning off old flowers. Always cut back to an outward facing branch-let with five leaves. There are hormones there that will cause a new rose to grow much sooner than if you cut to one with only three leaves.

About Roses

Roses are the flower of love. Many of us have fond memories of favorites in our mother?s garden or of a beautiful bouquet given or received on Valentine?s Day. It?s dormant season for roses which is good for both pruning and adding a few to the garden.

As a designer I have clients who have inherited roses and want to keep them as a remembrance. Others want to create a cutting garden filled with roses and other perennials. Don?t feel guilty for growing those beauties in your own garden. They use less resources than you think and there are many ways to grow them sustainably.

Roses, whether bush types, climber or ground cover carpet varieties, use a moderate amount of water in order to thrive according to the latest Water Use Classification of Landscape Species (WUCOLS) list. This amount of summer irrigation is the same as many of the plants on the list of Scotts Valley Water District?s 800 Approved Low Water-Use Plants for lawn replacement. Plants such as Emerald Carpet manzanita, Joyce Coulter ceanothus, Siskiyou Blue fescue grass, Pacific wax myrtle, butterfly bush, yarrow hybrids and Tapien verbena have similar water requirements.

Since now is the time to prune your roses here are a few tips.

Strike it Rich hybrid tea rose

Prune shrubs moderately to keep them compact. The goal is to keep the center of the plant open for good air circulation aiming for a vase-shaped bush with an open center. Cut out canes that cross, appear weak or are diseased, spindly or dead. Healthy canes appear green or reddish while old and dying canes are brown. Cut back the remaining stems by about one third. When pruning, cut canes at a 45-degree angle just above an outward facing leaf bud or a swelling on the cane. Clean pruners after every use to prevent the spread of disease and keep your pruners sharp.

Prune heirlooms roses such as David Austin and other old antique garden roses less because their open look is part of their charm.

Same goes for climbing roses. Cut out extra stems if there are too many and also cut back long established canes to about the place where they are slightly thicker than a pencil. Then cut each side stem down to several inches. This will make the cane flower along its complete length for a beautiful spring display.

Pluck off and rake away any old leaves. They can spread fungal spores. Consider spraying dormant plants with a combination of organic horticultural oil and copper soap or lime-sulfur. If you usually only have problems with black spot you can use a mixture of 1 teaspoon baking soda with a few drops of light horticultural oil in 1 quart water and spray every 7 to 10 days during the spring.

Prune your roses throughout the growing season, too. Deadheading, or cutting off spent flowers, encourages plants to re-bloom. Mulch around your roses to conserve water and encourage soil microorganisms.

Don’t worry whether you’re pruning job is perfect. Roses are super forgiving and you can always trim them up again later.
