I inherited two apple trees and a cherry tree on the property I bought 5 years ago near Owen Sound in Ontario. They are about 7 years old now. One of the apple trees is a hybrid of three kinds. I don’t like to use pesticides but the yellow apples especially, are spotty and deformed. One branch touches the ground and I will cut that off before it gets leaves in the spring. What can I do to help these poor trees in an organic way.
