Applying dormant sprays in the fall and winter is a great way to reduce overwintering pests & diseases in the home orchard. Dormant oils are applied when trees have dropped their leaves and are dormant. The oils can be applied when daytime temperatures are over 35-40°F. Dormant oils control aphids, scale, spider mites and many other insects by smothering eggs and larvae. To control diseases such as peach leaf curl, a fungicide is applied multiple times throughout the dormant season. An easy way to remember when to apply is after leaf drop, New Years day (or around that time) and a final treatment on Valentine’s Day (before bud break).
