Neem oil application
Best times to apply Neem oil to fruit trees for insect and fungus control.
Douglas County Oregon
Neem is best used in the active growing season after bloom to control aphids, and scale insects, and to control black spot on rose, rust on rose, scab on apples, and mildew diseases on fruit and ornamentals. It is not an effective dormant spray for fruit trees since no leaves are on plants yet. Please read the label on your container for more details about growing season controls.
