I’m starting to have doubts M. Californica is a compatible rootstock for yangmei...if it is, it’s not a very good one. After initially pushing, all my Yangmei grafts on M. Californica died. I also have a friend that’s been trying to graft yangmei onto Californica for awhile with no luck. It’s like Fang says, it’ll look like they’re compatible because the scion will push, sometimes even for months, but it will eventually always dry up and die.
Shane, it would be awesome if you could do an experiment by grafting some scions from your male tree onto some M. Californica.
Natty, have you experimented with different rootstocks for your yangmei tree?
I believe yangmei rootstock is the only way to go for grafting yangmei scions. I hope someone can prove me wrong.
