Please help!!
I purchased one sour apple tree from a local nursery about six years ago.
Maybe three years ago I noticed it was starting to grow separate down at the base. Last year it had two fruits only and the Iguana’s got them before I did.
This year it does have more fruit and I noticed that each of the own little tree is bearing one or two fruits each.
So the question is what to do to make it a healthy one tree?
