Don't know. But I find grafting cherries onto cherries difficult. Low take rate.

Someone else was wondering this a few months back I think... or maybe it was regarding chokecherry. Anyway, I did read somewhere that Prunus besseyi (Hansen's Bush Cherry, aka Western Sand Cherry) as a rootstock makes a short-lived plant.

In any event, I have trouble imagining the sizes matching up, sand cherry is such a small plant with super thin growth, while sweet cherries always have big thick twigs, right?

I budded several sweet cherries this past summer...i won't know what took for a few months yet. I find growing sweet cherry from seed almost impossible.

Frank - Was this a graft or did you root cuttings? If a graft, what were the two varieties.

Charlie,
Prunus besseyi aka Hansen bush cherry aka western sand cherry are a closer match with plums than cherries.

cHARLIE-

These were buds from cuttings i took off another sweet cherry and placed them on the trees i wanted them to go on. Just remove a bud and insert it on tree...wrap and rubber band. Th e buds look good still..i'll take pictures and update when they start to wake (its still cold here...maybe in 10 day sor so).
