Hardy Cherry Plum Pollination?
These have been the most mystified species for cross pollination. I grow several now but fruit set is extremely low.
I'm talking about Manor, Oka etc.
Which is doing the pollination for you?
So far, sand cherry, [Prunus besseyi] seems to be the best as they say,.. what is your thought on this?
