Question
I know you aren't an expert on fruit trees, but as there doesn't seem to be one, I have to ask you. During this period my gardening book advises me to tar wash my apple trees. However this would get rid of the good bugs on the trees and I wish to use an organic wash. How do I make one that will kill the baddies and leave the goodies?

   Thanking you, Myfanwy.
