I am on the verge of submitting a major grant proposal for an experimental
orchard that would use Prunus americana as rootstock for a plum orchard.
Prunus americana is sold as a rootstock occasionally, so I assumed it
could take P. domestica (european) grafts, but a few people this past week
have suggested that it's only for grafting american plums (beach plum,
chicksaw, etc.) which is not whayt I'm writing a grant for.
Does anyone have experience with P. americana as a rootstock for grafting
cultivated varieties *of any kind* that could chime in with experience?
Would greatly appreciate it.
John Bunker, thanks for presenting the pollenation problem with plums so
clearly and *concisely*! Very helpful.
