It's a good time to spray ornamental plants and fruit trees with dormant oil spray. Dormant oil is effective in controlling certain scale insects that can stay on your plants during the winter months. Dormant oil applications must be made when the temperature stays above freezing for 24 hours.

Question: I have some apple trees that are not doing well. For about three years now, they come into bloom really nice and form small apples. Then, most of the apples fall off. We had a hard freeze after the apples started to form. Could this be part of the problem? I spray dormant oil on them in March. The few apples that do mature are deformed. Please help. Answer: Young apples can drop off trees for several different reasons, and, because this has happened to you for three years, it seems there is a combination of factors at play.

Apply dormant sprays to deciduous fruit trees after leaves fall off completely. Spray Lime-Sulfur "Dormant Disease Control" mixture within the next few weeks to stop fungus diseases from getting a new foothold later in spring. Spray dormant oil to smother overwintering insect pests hiding inside the bark. Both products are commonly available at home and garden centers.

Within the next two weeks you can start your own peaches, plums, nectarines and other deciduous fruit trees from 24-inch cuttings. Protect your stone fruit trees from borers (moth larvae that feed inside tree branches.) Cut out severely damaged branches, if necessary, then spray the leafless tree with "dormant spray," a mixture of five tablespoons of "Ortho Dormant Disease Control Lime- Sulfur Spray" and five tablespoons "Volck Oil Spray" per gallon of water. Apply this on the ground around the trunk, then up the trunk, and over all the supporting branches.

Last summer my holly got a black powdery substance on the leaves which is still present. Can you recommend a treatment? You're seeing sooty mold, a fungus that grows on a substance called honeydew. Honeydew is excreted by scale insects. The scale insects are damaging your plants more than the sooty mold. To control scale, spray with a horticultural oil during the dormant season. Read more about soft scale on our Web site's Plant Diagnostics.

Reminder to those of us who haven't yet applied dormant spray to our cherry, nectarine, peach and plum trees: Do it now. They need protection from diseases and borer insects. Cut out any severely damaged branches, then spray the leafless tree with "dormant spray," a mixture of five tablespoons "Ortho Dormant Disease Control Lime- Sulfur Spray" and five tablespoons "Volck Oil Spray" per gallon of water. This will kill fungus disease spores and borer larvae or pupae that are hiding inside your tree. By the way, don't use sulfur- containing products on apricot trees. Use of the Volck Oil Spray alone is usually sufficient for apricots. Clean up daylilies and start new plants by snipping off the leafy little plantlets that developed on old flower stems. Leave a couple of inches of the fl...

Start sowing seed for your spring vegetable garden indoors now. Make sure to keep the soil moist but not soaking, and place the seed trays in bright, indirect light - not full sun. As seedlings emerge, gently rub your hand across the tops every few days. Studies have shown that simulating the wind in this way will lead to stronger stemmed plants as they mature. If you potted daffodil or tulip bulbs in fall for forcing, by now they have received the required three months of cold (40 degree ) temperatures. Move them back into the light, and water sparingly to encourage bloom. If you didn't find time to force bulbs in November, take advantage of the wide selection of potted flowering plants available this month at the florist shop. While most were forced for Valentine's Day, who says you n...

This is the time of year we begin to plan for our summer annual color and container plantings at the Dixon Gallery and Gardens. This year we anticipate using fewer tropical plants in containers and more outdoor hardy plants. The tropical plants are always stunning, but require constant pruning and maintenance and need to be changed out several times a year. This new approach is more sustainable and can be just as attractive. Instead of replacing the contents of these containers several times a year, we can leave the hardy plants in for a longer time and eliminate the "first frost" crisis that occurs every fall.
