I'm hardly anything more than a novice with stonefruits - and I've
virtually abandoned all of them that I currently have planted - I'm just
waiting on the borers to take 'em out so I can replace them with pears or
persimmons - but I have grafted a few, with reasonable success.
I've done simple whips or W&T of dormant scions of both Euro & Jap hybrid
plums onto native plum(P.angustifolia?), P.americana, and Nanking
cherry(P.tomentosa) with good results - after the rootstocks had fully leafed.
I've done summer budding of peaches and Jap.hybrid plums onto both
P.americana and P.tomentosa.
A friend sent me an assortment of sweet cherry scions this spring, and some
Tomcot wood, as well. It all stayed in the fridge, as I really wasn't too
hep on even trying 'em, but I figured Don Yellman liked Tomcot so much that
I'd give it a try anyway. I did W&T of one piece each on P.americana &
P.tomentosa - long after they'd leafed out - heck, I think the Nankings had
already bloomed, and both are growing quite nicely, right now.
Another friend sent some Stanley scions, and I just fostered a couple of
pieces onto the Green Gage, Peach, and unidentified Euro plum selection Lon
sent me years ago(It lost the label, and I can't recall now if it was the
Burbank Seedless or a numbered selection). W&T grafts, done in early May,
all seem to have taken and are growing nicely.
