I have some water shoots coming out from the root systems of larger cheery trees. I have been digging some up in hopes that will develop into trees and wondering if the will bear fruit, or if not will I be able to graft onto them if not. i am not sure if they will be a good root stock as they have a larger than normal root due to being from the root of the larger tree. Next question I have a lot cherry tree seedling from a one of those small cherry type of a tree. I have so many of them am I able to graft other types of cherry tree branches onto them. David
What the suckers might grow into depends on what the parent trees are. Sweet cherry has been used for rootstock quite a bit, maybe they're just sweet cherry seedlings of undemonstrated fruit quality. Or it might happen to be a planting made with a named, clonal rootstock cultivar. Either way I wouldn't count on good fruit, maybe they would be OK and maybe not.
