My Oregon Grape Holly is infested with whiteflies. What can I do to repel them or remove them?
Whiteflies have infested one of my Oregon Grape Holly plants. How can I remove or repel them. But this may be complicated because I am on quite severe water restriction due to ongoing drought conditions and I don't use systemic pesticides in my garden. Is there any help in sight?
