Adam, can you provide some pruning tips?
Also, would that be a good opportunity to graft, say, a red hybrid scion from a fruiting tree, onto them? If so, I will be placing an order with a reputable company I've heard of called "Flying Fox Fruits"
its simple really..
u r trying to encourage the oldest thickest branches to become thicker, and less shaded, by smaller branches.
so remove a bunch of the smaller branches, so the older branches have more light exposure.
I appreciate the kind words about my nursery! but honestly i wouldn't graft onto these trees....unless you want to make a project out of one of them...i suppose you could graft on a bunch of varieties, or just top work the tree with a different variety.
