The February Garden

Wait to prune Flowering Currant until after flowering.

Hopefully these cold mornings will be a thing of the past by the time you read this. My plants were much happier right after the rainsI when nights were mild. ’m waiting patiently for the buds on my pink flowering currant to start showing color. I saw some recently in Felton that were already opening. Mine are still pretty small at this stage but 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. Here are some February tasks that I am doing.

To stimulate new growth trim woody evergreen shrubs like abelia and loropetalum soon. Cut Mexican bush sage and artemisia 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.

Fuchsia ‘Firecracker’

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. A plant is wasting energy on new growth if trimmed later. Let your plants dictate when the time is right. Every garden is different and in microclimates in your own garden temps can vary widely.

My previous hydrangea garden.

Cut back hydrangea stems that bloomed last year and apply a soil acidifier if you want blue flowers. 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, spirea, flowering currants or flowering trees such as cherry, plum and crabapple now. These and evergreens like rhododendrons, azaleas and camellias 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 pruned your roses be sure to remove old leaves still clinging to the plant even if the leaves look okay now. They 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

Wait to prune back perennials that may have their new foliage damaged in a late hard 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 now.

Cut back ornamental grasses if you live where you rarely get frost. When I grew California fuchsia, salvia ‘Bee’s Bliss’ and hummingbird sage I’d prune now to encourage new, compact growth.

And remember to enjoy your time in the garden. It’s only work if you think of it that way.

Don’t prune Pink Flowering Currant until after they bloom

I’m waiting patiently for the buds on my pink flowering currant to start showing color. They’re still pretty small at this stage but 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. Here are some February tasks that I am doing.

I’m not sure if it’s me or my plants that are confused. They probably know exactly what they’re doing. That long warm spell this January stimulated many plants to start growing early. What’s a gardener to do when the roses, fuchsias and many other plants never really became dormant this year?

To stimulate new growth I will trim woody evergreen shrubs like abelia and loropetalum. Cut Mexican bush sage and artemisia 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.

Pruning Plants in February

My plants are confused. Actually they know exactly what they are doing it’s me that’s confused. The mild winter, so far at least, has encouraged many of my plants normally still dormant at this time of year to start growing for the season. What’s a gardener to do when the roses, fuchsias, oakleaf hydrangeas and many other plants never really went dormant this year? Here are some February tasks that I’m going to be doing.

Cut back woody shrubs to stimulate lush new growth. Trim plants like Mexican bush sage and artemisia to within a few inches of the ground. 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.

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. Do this right away if you haven’t already done so. A plant is wasting energy on new growth just to have it trimmed off later.

Cut back hydrangeas stems that bloomed last year and apply a soil acidifier if you want the flowers blue. 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.

Miss Kim lilac

Don’t prune spring flowering shrubs like lilac, weigela and spirea or flowering trees such as cherry, plum and crabapple now. These and evergreens like rhododendrons, azaleas and camellias 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 pruned your roses be sure to remove old leaves still clinging to the plant even if the leaves look okay now. They 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.

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.

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.

Fall Tasks in the Garden

Some people wait all year for fall weather to arrive. The heat of summer is over and the tourists are gone along with that pesky fog along the coast. For us up here in the Santa Cruz mountains, this is one of the best times to be outside. Here are tips for early fall in the garden.

Late fall is not a good time for major pruning so if you have some shrubs that need a tune-up do it soon.  Wounds heal slowly later in the fall, leaving them more susceptible to disease. As a general rule, don’t prune when leaves are falling or forming. Wait to prune most trees until late in the dormant season or in late spring after leaves and needles form. To avoid sap flow on birches and maples, prune after leaves mature. Fruit tree summer pruning should have already been done when growth ceased.

Refresh perennials, such as butterfly bush, salvia and yarrow by cutting a third to half of their growth later in the fall.

Rake leaves- compost or put in your green can. If large leaves are left in place they will mat down and set up fungal problems come spring.

Remove dead and diseased leaves from under camellias, rhododendrons and roses.

 

Bearded iris

Now through October, divide summer blooming perennials that are overgrown and not flowering well. Alstroemeria, agapanthus, coreopsis, iris, daylily, yarrow, rudbeckia, calla lily, aster and penstemon fall into this category. You can also divide spring blooming perennials like candytuft, columbine, astilbe, bergenia and bleeding heart although they don’t always bloom the first spring afterwards due to the energy they use re-establishing themselves. If you’re on a roll out in the garden, though, go for it now. You never know what other projects you may be working on next spring.

Start perennial flowers seeds now so that they will be mature enough to bloom next year.

Fertilize shrubs lightly one last time with an all-purpose organic fertilizer or layer of compost. Use compost only on California natives.

broccoli with sweet alyssum

Plant cool season veggie starts like broccoli, cabbage, cauliflower, chard, lettuce, spinach, brussels sprouts, onions and leeks in soil enriched with 4-6″ of compost as summer vegetable crops will have used up much of your soil’s nutrients.You can sow seeds of beets, carrots, radishes, spinach, arugula, mustard and peas directly in the ground. Planting early ensures your plants get a good start before cold weather sets in and growth mostly stops until spring. You’ll be able to start harvesting in just a couple months if you start now that the weather has started to cool.

If you aren’t going to grow vegetables in the garden this fall consider planting a cover crop like bell beans, fava beans and vetch after you’ve harvested your summer vegetables. Next month I’ll talk about how to go about doing this and how this benefits your soil.

Cut back berry vines that have produced fruit. Canes of the current season should be trained in their place.

Spider mites and thrips are especially prolific during the late summer. If some of the leaves on your plants are pale with stippling, spray the undersides of infected leaves with organics like insecticidal soap switching off with neem oil as they build up a resistance to one of the pesticides. Plan to spray with a horticultural oil in the winter to kill overwintering eggs.

Making the Most of your Garden

Early summer is the right time for many garden activities that you don’t want to leave to chance. Keep these reminders in the back of your mind to tackle when the mood hits you.

Pink wisteria in bloom before summer pruning

Look for any pest problems so you can do something about them before they get out of hand. I’m OK with a few holes here and there but a heavy infestation should be trimmed off or sprayed with an organic insecticide.I inspect the tips of my fuchsias regularly for fuchsia mites and clip off any distorted growth. I hate to spray even organics on fuchsias due to the hummingbird activity. Lately I’ve seen rose slugs making lace out of the leaves so I crush by hand or spray with organic BT. Walk around your garden with a beverage in hand to spot problems on a regular basis.

Many plants, both vegetable and ornamental, are bothered by aphids and other sucking insects as well as foliage and flower eating bugs. From cucumber beetles, flea beetles, stink bugs, weevils, curculios to borers , the list of trouble makers is endless.

To help deter them mix up some pepper spray in your kitchen.

  • 1 tablespoon hot pepper sauce or 1 teaspoon cayenne pepper
  • 6 cloves garlic, crushed
  • 1 quart warm tap water

Let stand I hour, strain and spray plants either in the morning or evening.

If you battle dandelions and don’t want to use chemical weed killers around pets and children, get out the white vinegar from the cupboard. On a hot sunny day spray straight white vinegar directly on the weed. This method will kill whatever it touches so direct the spray carefully. If the dandelion is in the lawn, wait a week, pour some water on the dead spot to dilute any lasting effects of the vinegar. Then poke some holes and drop in grass seed. Sprinkle a bit of fertilizer where the seed is planted and keep the area moist. In three weeks you won’t remember where the dead spot was and the dandelion will be long gone.

Another garden to-do this month includes summer pruning of wisteria. To increase flowering next spring and keep these vines under control cut new growth back to within 6″ of the main branch. If you want to extend the height or length of the vine, select some of the new streamer-like stems and tie them to a support in the direction you wish to train the plant.

Twist off spent rhododendron flower trusses

While I have the pruners out I’ll be shearing back early flowering perennials to encourage another round of blooms. The season has just started and you’ll be enjoying lots more flowers in the months to come if you deadhead regularly. Perennials and shrubs that benefit from trimming an inch or two below the spent blooms are erysimum, lavender and Pink breath of heaven which will keep them compact.

Twist off spent rhododendron flower trusses and fertilize them.

Apply the second fertilizer application for the year to your citrus and fruit trees. The last one should be immediately after harvest. Apply the fertilizer to the soil around the drip line of the tree where feeder roots are located and scratch into the surface. Water in well. As with all fertilizers, make sure the trees are moist before you fertilize. Young trees in their first, second or third growing season should receive half the rate of established trees.
