    Galls Are Just Swell

    Just reading up on spruce gall. Everything I read states the best time to treat is in the spring. Would there be any benefit to treating it mid to late summer with either systemic or residual? Or, is the damage already done?

    Fig Whitefly Remedies

    Fig whitefly - where did it come from and what is the cheapest way to control it? Is there any home remedy such as liquid soap, garlic, or something natural, even if I spray monthly. I know about systemics, but they are very expensive.
