Pruning and Plant Health

My conclusions about the yellowing of the leaves is that it was not an iron problem, but there were big changes in temperatures of the week. I believe this caused a hormone imbalance in the trees and turned the leaves to yellow. There was also was looked like apple scab that was attacking the leaves. To combat that I sprayed a copper fungicide which seemed to work.

I do not know if the fertilizer did anything other than it started to produce some sort of fungus which was concerning but as time went on it seemed not to damage the plants at all.

In order to combat this I had to prune back the root stock shoots. The root stock shoots and leaves were crowding the grafted leaves so much I do not think they were able to dry. Taking off all the root stock shoots really opened up the tree and everything seemed a lot more open. I think this will help tremendously after I water the plants. It will allow them to dry and grow more.
