I grow the trees, but no fruit yet, even though I planted Tam Kam in 2011. It has had too much die-back, sometimes almost to the ground/graft. Chinebuli is supposed to be hardy to -16F (per Englands). I had a small graft of it which died last winter, but I think part of it was that it wasn’t near the top of the tree and I’ve been told that persimmons self-prune such wood.
I’m giving up on NA persimmons at home, but I do own some other properties a few miles (and half a hardiness zone) closer to the ocean where I’m planning on planting Tam Kam, Ichi Ki Kei Jiro, and Gwang Yang. I also moved the struggling Tam Kam and Izu from my yard.
