February in the Garden

Our beloved banana slugs are crucial decomposers in the redwood forest.

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.

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 if trimmed later.

Cut back hydrangeas 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 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 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. 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.

All About Roses

Hot Cocoa was introduced in 2020 but it’s still a popular selection

January is almost over with nary a raindrop since January 5th as I write this although there is some in the forecast. Our days have been lovely and many of my plants have started growing earlier than usual. Guess I can’t put off pruning my Compassion rose any longer. I see some outstanding new rose varieties available for the new sseason. It won’t come as a surprise that they are very fragrant and have good disease resistance So while you’re out in your garden pruning your existing roses consider adding a new one or two now available Here are a few that caught my eye.

Fashion Forward, Light Years Away, Living the Dream and Nothing But Class all have strong disease resistance as well as a strong fragrance.

Pretty Picotee is a newer hybrid tea rose with huge, bright pink petals with white edges and a citrus fragrance. It’s resistant to powdery mildew and rust which makes it rank high in our climate. In Love Again is another newer variety with very high disease resistance to black spot and downy mildew in addition to rust and powder mildew. The vivid red flowers are exceptional performers with a light fragrance.

If you are looking for a smaller rose that grows to 24 inches and has both strong fragrance and disease resistance, Easy Charmer is the rose for you. With old fashioned cupped fuchsia lavender blooms this rose would look great in a container on your deck. If your garden is in partial shade but you still enjoy roses, try the new floribunda Time After Time. It has considerable disease resistance which enables it to thrive with minimal upkeep.

But what about pruning those existing roses in your garden? First of all remember that roses are super forgiving so just go for it and you can trim them up again later. Here are some tips to get started.

Most of us want our rose bushes to produce lots of roses on a compact shrub and not just a few exhibition size blooms so prune your shrubs moderately. 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 Slant the cut away from the bud to encourage growth outward. Clean pruners after every use to prevent the spread of disease and keep your pruners sharp.

Heirlooms roses such as David Austin, other old antique garden roses, and floribunda roses require less pruning because their open look is part of their charm. Keep this in mind and prune lightly. Old garden roses that bloom once in the spring should be pruned after flowering.

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.

It’s best to prune your roses before they start leafing out or some of their energy will be wasted. Pull 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 s10 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.

Bare Root Edibles

Bartlett pears can live for over 50 years in your garden with good care.

A visit to any of our local nurseries at this time of year is like a visit to the candy store for a gardener. There are so many exciting edibles available now and this is the time to get yours. How lucky am I that I get to recommend some to new property owners looking to create an edible landscape. Here are some that caught my eye at Mountain Feed & Farm Supply in Ben Lomond.

If you have limited space there are multi-graft trees that combine compatible pear, peach, apple, plum and nectarine. There’s even a “fruit cocktail tree” that combines totally different stone fruits.
For really small spaces maybe a Garden Delight Miniature Nectarine would be perfect. This tree is a heavy producer of sweet, freestone delicious fruit that ripens in August on a tree that’s only 5-6 feet tall. The beautiful pink flowers in the spring are spectacular.

Besides classics like Elberta Peach and royal Rainier Cherry, what about planting a Candy Heart Pluerry, a cross between plum and sweet cherry? Or how about a Cot-n-Candy Aprium, an apricot-plum hybrid with incredible flavor? Or maybe a Flavor Grenade Pluot with its explosive flavor? This taste test winner produces fruit that hangs on the tree for 4-6 weeks which is a real plus. If it’s a new cherry tree you have in mind, consider Craig’s Crimson. This taste test winner produces dark red, to nearly black, medium to large size fruit with a wonderful spicy flavor. And if you get overwhelmed with everything ripening at the same time in the summer, maybe a Carnival Peach which ripens late September to early October would be a welcome treat.

And I haven’t even started on all the blueberries, grapes, goji berries, gooseberries, boysenberries, raspberries, strawberries and not to be forgotten-the delicious fruiting mulberry all available now in bare root form.

Planting a bare root tree is easy. In most soils, even sand or clay, bare root trees are best planted in your native soil. Less is more when it comes to amending your soil. You want your tree’s roots to reach far into the surrounding soil, and if you have added too much amendment, the roots will tend to grow only in the richest soil right around the tree. You can add a starter fertilizer like Dr. Earth Root Zone or E.B.Stone Sure Start with mycorrhizae organisms and micronutrients, otherwise wait to fertilize your new tree after a year.

Don’t plant in heavy saturated soil. If your soil drains poorly it’s best to place your tree at an angle in a trench and cover with soil or place it in a can. Wait to plant until the soil is crumbly and friable. Digging in waterlogged soil is one of the worst things you can do for your soil’s health. Do a drain test by filling the hole with water. If the spot you’ve chosen doesn’t drain in 3-4 hours, then plant in another spot or on a raised mound.

What fruit trees can you grow here in the mountains? Well, almost everything. Most of us get 700 hours of winter chilling or more where the temperature is below 45 degrees. Even with climate change the chill hours add up. And we can still grow fruit like a Fuji apple that doesn’t require this much chill.

What if you don’t get full sun where you’d like to grow fruit trees? Apples, pluots and plums are good choices for an area that gets at least 5 hours of sun a day during the growing season. The ideal is full sun but these trees will still set and ripen some fruit in partially shaded conditions. With peaches, nectarines or apricots it’s a different story. These fruits need hot sun to develop sweet, tasty fruit. Too little sun and they will not deliver anything close to what you have in mind.

With a little planning you can have fresh fruit 7 months of the year. By growing your own fruit you’re not at the mercy of mechanical harvesters and shipping practices. You can grow fruit and harvest it when the time is right. Homegrown fruit is a world apart from agribusiness and much less expensive than the Farmer’s Market.
