I am growing just about every Euro, Japanese, Hybrid and otherwise that exist in WV… i will struggle with Black Knot, Plum Curculio and Brown rot etc etc etc… (probably/maybe/likely)… so YMMV.
As for nurseries… i have ordered from all of them i think coast to coast.
If i had to pick one it would be Mehrabyan. The other choice would be Grandpa’s Orchard.
