As a beginning apple grower in New England, with a small orchard of
dwarf trees, what do I need to know about apple borers? I have put up
window screen cylinders with foam collars to keep borers out, and I am
willing to scout the trees regularly. However, I don't know how big a
hole I should be looking for. Any one have any recommendations for how
to deter and how to recognize borer damage in apples?
