Chills,
I started grafting so each tree would have its own internal pollinizer. I wonder if my insects are lazy, and instead of going from tree to tree, they stay in the same tree going from branch to branch. There is always the issue of some grafts have more vigor than others, but I putter around anyway so pruning shears take are of that issue. Now I am carried away, and each tree is becoming a multi-graft. I figure it’s a fun way to try many multiple varieties in a limited space, for low cost. If a variety doesn’t work out, I can easily prune it off. Plus, I can have early, mid, and late bearing on the same tree. I don’t need bushels of each, so I like this method.
I’ll update on Mango pawpaw as the season progresses. Sorry yours didn’t grow. I think Mango is a Georgia variety.
