When is the best time to apply Bonide All Season Horticultural Spray Oil for red galls on a sugar maple?
when would you apply this product to a maple tree infected with red galls? I know the galls don't harm the tree but I don't like the way that it looks.
Application timing will vary from region to region. We recommend contacting your local cooperative extension office and speaking to the master gardener on staff. The master gardener can you usually provide your with the best application times in your region.
