Now is the time November to spray your fruit trees with dormant oil available at the lawn & garden center. We spray according to the directions on the label. In the spring when the snow is still on the ground we start the spring spray all the way up to the bud stage.....once the bud opens we only spray the trunk up to the bottom branches. Wear old long clothes, hat, goggles, mask & gloves, don't spray if it is going to rain or it is windy. We have 100 fruit trees and this has been working for us since we started planting fruit trees in 1970.
