So I have this severely overgrown apple tree that the previous owners of our house were trying to train to an espalier. I would assume it is at least 3 years old.
My problem is that I want to keep the tree but I don't think there is enough room for it to grow apart from the espaliered form. Unfortunately, the tree was left so long that much of the growth is very high up and the branches that are trained against the espalier are very thin. Is this tree salvageable? It looks kind of sad now because it had a bunch of vines taking it over. I pulled all of that out and was left with this.
Also I am zone 7a.
