022504 This past week the first of many tree orders was delivered to the nursery at the Belle Mead Co-op. That signals the beginning of spring for me as the nursery manager. Over the next month garden centers will be receiving the many orders of new trees and shrubs. It is a good time to start shopping and gathering ideas for the planting season. As soon as the ground is workable (thawed and not soggy) the trees and shrubs can be planted. Until planting time there are a few things you can do in preparation for the gardening season. First take a good look at your tools. Sharpen pruners and loppers. Smooth out rough spots on wooden tool handles. Tune up mowers and tractors. And check hoses for cracks and possible leaks. Once the tools are ready, head out to the garden for late winter pruning. Fruit trees can be pruned now. Young trees should be pruned to train them to the desired shape. Older trees are pruned to encourage fruit production. Always remove dead, damaged or diseased branches first. Bring a few of the pruned branches inside for forcing. Once placed in water they will bloom in about three weeks. Grapevines should be pruned hard in late February. Brambles fruits, such as blackberries and summer bearing raspberries, can also be thinned out. Remove the canes that bore fruit last year- they will not bear fruit again. Blueberry bushes can be pruned by removing any dead branches. On older bushes thin the plant to six strong newer stems. This will encourage new stems to grow from the base of the plant. On a day when the temperature reaches into the 40’s apply horticultural oil spray on fruit trees and other landscape plants. This is your first defense in preventing insect pests. The oil smothers over-wintering insects and their eggs. For fruit trees and roses that had disease problems last season, a lime sulfur spray can be applied as a preventative. Oil and lime sulfur should not be applied at the same time on plants however. Follow label instructions carefully. Make a plan for this year’s vegetable garden. Map everything out on paper, remembering to rotate crops. Plan to plant tall crops on the north side of the garden so they won’t shade shorter varieties. Leave proper spacing between plants for good air circulation. Seed packets and plant labels usually have information on proper spacing. Plan to fill the spaces after early crops have been harvested with something that will be harvested in early fall. Seeds of the cool weather crops can be started indoors at this time. Broccoli, cabbage, cauliflower, leeks and onions are easy to grow from seed. The slower growing annual flowers can be started form seed now as well. Any that require twelve weeks or more from seed to planting time would be considered slow. All seed starting supplies need to be very clean. If you re-use pots and seed starting trays from year to year, sterilize them with a weak bleach solution before planting. Use a soil-less seed starting mix as a growing medium. Nothing is more disappointing than losing newly sprouted seedlings to damping-off disease. As long as all your supplies are clean it can be avoided. Most seeds germinate in warm temperatures and out of direct sunlight. High humidity is also helpful. Cover the trays or pots with clear plastic until the first sign of sprouting. A heat mat can provide enough warmth for many seed varieties. Or set the trays on top of the refrigerator until the seeds sprout. Keep the soil moist but not soggy. Once the seedlings are up, move them to a sunny window or under fluorescent lights. Keep the lights on for 18 hours a day and 2-4 inches above the plants. While unloading and inspecting the new trees that arrived this week I was intrigued by an interesting collection of tiny eggs on one of the cherry trees. They had been laid by some insect in a perfect diamond pattern on the trunk of the tree. It could have easily been mistaken for a piece of tape or cloth. At this time of year with careful inspection many insect eggs and cocoons can be spotted on bark and twigs. Insect eggs are often laid in neat rows or patterns. They will be quite small, oval or round and can vary in color. Most are easily removed by hand- simply scrap them off.
