I have a mini orchard consisting of a Braeburn Apple Tree next to a Stella Cherry Tree which is next to a Conference Pear Tree and on the end is a Victoria Plum. The apple tree has no growth on it at all year, no shoots nothing. I assume its dead. The cherry tree seems to be having the bark from the trunk eaten, it is quite bad damage but the tree is blossoming and seems to be thriving, the other 2 trees seem ok and are blossoming too.I have seen loads of ants on the cherry tree and they are going into the damaged bark. Will they cause any problems for the tree. The trees were 2 yr old when I got them 3 years ago (this is the third season) I've not had much fruit from them (only a couple of cherries from the cherry tree and nothing from any of the others). I feed with blood fish and bone and a slow release fertilizer and water regularly when needed. Will my cherry tree be ok and will I ever get a fruit from them? How long?
