I am looking for information on what type of seeds i should be looking for. I live in Canada zone 9a(but a very cool and wet 9a) i have a couple dozen red hybrids but have been told that they wont work for grafting. Id love to start creating some multigrafted trees with a variety of cultivars, what rootstock would you recommend? From what i have seen most people are using sabara?
Thanks in advance for any help you can offer,
Cheers
