What to Do in the Garden in February

Blue Nikko hydrangeaYou know spring is coming when you see daffodils starting to open. You know spring is coming when plum trees begin their glorious show. And you know spring is coming when you begin to think of all those garden tasks that still need your attention.

February is one of those months that ease us into the gardening season. Didn't get the roses pruned at the end of January? There's still time. Didn't dormant spray for fungal diseases and insect control? There's still time. Didn't plant any new berries yet for summer desserts? There's still time – but don't delay much longer.

What is important to do in the garden in February?

Prune fruit trees and smother overwintering eggs and insects by spraying with horticultural oil. Combine 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.

Prune your roses if you haven't already.

Prune repeat flowering roses by removing spindly or diseased shoots and dead wood. Do this before they start leafing out which wastes plant energy. Cut back the remaining stems by about a third, cutting canes at a 45-degree angle just above an outward facing bud. Don't worry whether your pruning job is perfect. Roses are super forgiving and you can trim them up again later. You want 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.

If any old leaves still cling to the plant, remove them. Rake up any debris beneath the plant and discard to eliminate overwintering fungus spores. It's a good idea to spray both the bare plant and the surrounding soil with a combination organic horticultural oil to smother overwintering insect eggs and a dormant spray like lime-sulfur or copper soap to kill fungus spores. If you usually have a problem only with black spot you can use a mixture of 1 teaspoon baking soda with a few drops of light oil in 1 quart water and spraying every 7 to 10 days.  Thoroughly coat the trunk, branches and twigs.

Cut back woody shrubs. To stimulate lush new growth on 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 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.

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. Although sulfur is the traditional favorite for quickly acidifying soil it is not as kind to many beneficial soil microorganisms. Coffee grounds, pine needles, peat moss and cottonseed meal are kinder to your soil.

Don't cut back grasses yet if you get frost in the area where they grow. Wait until mid-March.

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.  You can cut some branches during flowering to bring in cuttings for bouquets.

Wait to prune back perennials that may have their new foliage damaged in a late frost. Same goes for shrubs that got hit by those January frosts. That damaged foliage can protect the plant from further frost damage. Mid-March is the estimated date of hard frost in our area.
 

The Best Bareroot Varieties for your Garden

Imagine biting into that first apricot of the season. The juicy, sweet flesh the color of an orange sunset. Maybe a rich dark burgundy plum, sweet but slightly tart, makes you think of those summers when you picked them off the tree in your parents backyard. And then there are cherries, pears ,apples, peaches and nectarines to look forward to. Now is the perfect time to plant some of your favorite fruit trees while they are available in bare root.

plumsGrowing fruit trees in the backyard has come a long way in recent years. Even in season those organic peaches from the farmer's market are expensive when you load up a big bag 'cause you just have to have a couple of each variety after trying the samples. Starting a home orchard or adding to your own edibles during bare root season is the way to go.

With a little planning you can have a prolonged harvest of tree-ripe fruit from a small space. Maximize the length of harvest by choosing varieties with different ripening times. Then train those fruit trees to stay small by pruning them in summer (winter pruning tends to invigorate trees), plant them close together or you can even plant several in the same hole. Small trees yield crops of manageable size and are much easier to spray, thin, prune, net and harvest than large trees.

The hard part is choosing which will be your next fruit tree. I've talked to several experts about their favorites. Here's what they told me.

Orin Martin of UCSC Farm and Garden loves apples. His highest praise goes to Cox's Orange Pippin, Golden Delicious, American Golden Russet and Mutsu. Plant these varieties and you could be eating apples from August through October. Did you know that at one time in American history russet apples were the most desired and wages were actually paid in cider made from russet apples?

Sheila from ProBuild told me she has seen a lot of interest in new introductions such a Pluerry, a hybrid she described as plum meets cherry. Bella Gold Peacotum has also been very popular since being introduced last year by Dave Wilson Nursery. This peach x apricot x plum fruit has slightly fuzzy skin like an apricot but with a mildly sweet flavor all its own.

Flavor Delight aprium has become a favorite because of its resistance to brown rot. It's 3/4 apricot, 1/4 plum with the clean tang of an apricot boosted by the sweetness of a plum. This variety is also recommended by Orin Martin.

Spice Zee Nectaplum is another hybrid that is getting a lot of buzz. I've heard it described as being "just about the tastiest fruit… ever eaten- very sweet, with an indescribably rich taste and aroma".  Being a gorgeous tree with deep red leaves in the spring that gradually become a dark green by mid-summer makes it ornamental in the garden as well.

Chris and Dave from Mountain Feed like many of the heirloom fruit trees. If a variety is older than 50 years it is classified as an heirloom. Does that apply to people, too? In addition to apples, Chris told me about his favorite pear, Belle Lucrative, which he described as an amazing French butter pear. This classic variety of 19th century France has a juicy, syrupy melting texture.

Plums are also high on his list of favorites. Luther Burbank varieties such as Elephant plums_on_the_treeHeart, Beauty, Inca and the ever-popular Santa Rosa are easy to grow and need very little care once established.

Bare root trees need to be planted while they are still dormant. Stone fruits such as apricots, peaches, plums and cherries are going to start waking up first so they are best put into the ground soon. You want your tree to start developing its new permanent roots in its permanent home. Fruit tree like pears and apples will be dormant for a while longer so you can wait a bit longer to plant them.

Take advantage of bare root season to add more edibles to your landscape. A smart design can make your garden look beautiful while feeding your family.
 

Saving Water in the Garden

With so much rain this winter it's easy to forget just how precious water is. Globally, water is the new oil. In our own Santa Margarita aquifer everything we can do to replenish the groundwater is vital for our own survival and for that of generations to come. Water cost money – to buy, store, collect, pump, filter and distribute. It just makes good sense to be water wise in your home and garden.

Scotts Valley Water District has been offering a free information series during January about water conservation. Each Wednesday night from 7:00-8:30 a different subject is presented. They are open to the public. I've attended two so far- Storm Water Management and Rainwater & Greywater Harvesting, lots valuable information about ways to save water and money.

When it rains it pours. Think about ways to slow this free water from the sky and prevent it from running off your property. Allow it to spread and sink into the ground. Easy ways to do this can also make for a beautiful landscape.

Design your patio using permeable pavers that allow storm water to percolate into the soil. Whether you choose flagstone over a gravel base, pervious concrete, interlocking pavers with spaces between or crushed gravel all enable rainwater to seep into the soil, recharge the aquifer and prevent runoff into streams and storm drains.

Pervious pavement for driveways can capture runoff , recharge the groundwater and keep pollutants in place in the soil. Large volumes of runoff causes serious erosion and siltation in rivers and streams. Naturally occurring micro-organisms digest car oils, leaving little but carbon dioxide and water. Turf block (concrete blocks with holes) is a good choice for areas that don't receive a lot of heavy traffic and can also be used for paths with gravel or groundcover between.

Plants and trees also slow water runoff. They help stabilize slopes and prevent erosion of valuable nutrient-rich topsoil. They create wildlife habitat and act as a natural pest control. A beautifully designed landscape using California native or drought tolerant plants reduces the need for fertilizers, pesticides, excessive watering and overall maintenance requirements.

You can design a rain garden to capture stormwater runoff from roofs, driveways and other impervious surfaces and allow the water to sink back into the ground. A dry creek bed can also be a good way to slow runoff. Some utilize drain pipe underneath to capture the rainwater so it has time to percolate into the ground.

Using vegetation or mulches to cover bare soil is a key ingredient to slow down runoff. 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, conserve soil moisture and prevent weed growth. It's all part of the plan to slow, spread and sink water back into the ground.

Installing a rain barrel is a simple way to catch rainwater runoff from your roof. If you have room you might consider a large water tank above or below the ground to collect water. A friend of mine operates a small nursery on her Watsonville property. Sherry and her husband, John, decided to collect the rainwater runoff into a series of tanks to save money and utilize this resource. The 4500 sq.ft roof of their barn provides enough water to fill 3 large tanks. Last year they collected enough water to irrigate their nursery, Terra Sole, for quite a bit of the year. They eventually plan to install solar panels to offset the energy required to pump the water. Every little bit helps

If you'd like more information and ideas about how to beautify your landscape and save water, maintenance costs and time  please come to the last Water Wednesday presentation by Scotts Valley Water District on Jan 30th at 7:00 pm at their office on Civic Center Drive. LeAnne, the water conservation coordinator, and I will be showing slides of landscapes, some of which I designed, that feature low water use plants, lawn replacement ideas and California natives. There's a solution for every family and lifestyle.
