I have one of these on order. I don’t have any other plumcots , but I have lots of Japanese/American hybrids ( no Japanese plums), and Prunus Americana and Prunus Nigra…will I be OK for pollination ?
Flavor Supreme pluot is difficult to pollinate. My issue was the bees aren’t interested in FS flowers. What you have may work if they bloom together and the bees help out.
I had to resort to hand pollination. It’s worth the effort because it’s a tremendous fruit.
For some reason, out in the Central Valley CA the bees seem to really like mine. I have to thin it like crazy.
