Approach grafted on glabra. graft applied first week of July. SOLD
My grafted tree came from Berto's fruiting tree.
Both trees I grafted flowered after grafting them.
My tree and Berto's tree are on glabra rootstock and seem to be fine long term. If I was growing it further north I might try montana.
This is my last one for sale and I have no other approach grafts applied yet.
