Jubileum pie cherry productive?
I have had this Jubileum pie cherry for about 5-6 years. It has given me one cherry and this year it has 2 more. Is there anyone on this list who is growing this cherry? The tree is 12 feet tall and 7 feet wide. IT's healthy just not productive. I even bud grafted on a small section of Danube pie cherry to try to cross - pollinate, which I know is not required but may improve fruit set.
Montmorency is reliable and productive for me. Northstar is productive but gets disease.
How many cherries are the rest of you getting on Jubileum or other pie cherries? I wonder if I should graft it out.
