Not pictured is "mango" which I think was planted 2013 0r 2014.
Allegheny has not bloomed yet but looks pretty vigorous. I think I planted it in 2015 or so.
NC-1 is the most vigorous but Sunflower set by far the most fruit this year, which is the first year any of them have had developing fruit this far along. I hand pollinated between these trees. Both Sunflower and NC-1 have several trees a foot or two from the main trunk, which would be the rootstock. I might leave those in place, since they could be pollinators for the main tree. Sunflower looked a bit frail last year, but seems to be better this year.
When I planted these trees, I was so concerned about reported fragility of the roots, I did not untangle them. I don't know if I would take the same approach now. It might be better to bare root them, gently, using a stream of water.
