We have an orchard of 30 apple trees that has not been touched in about 20 years. The trees do bare apples - however, the trees have not been pruned. We have lived in the house only 3 years, and I have not had time to work with the trees. I would like to rejuvinate them, is it possible? They produce the apples, but they are not really great. We let them drop to the ground for the deer - our reward in the past has been venision, however - I would love to try working with the apple trees so we are able to have fresh apples.
