My house came with a Santa Rosa house. Last year it died down to the rootstock and the rootstock shot up. This year it flowered and has fruit that appear to be peaches. Does this give any clues on the possible rootstock?
I am trying to decide if I should dig it out or graft onto it.
I would first let the fruit ripen. There’s no way it could be harmful to eat, and if the plum was grafted to a peach seedling you might have a perfectly good peach. And you could always graft a new plum to one or more of its branches.
Great, thanks. Hopefully I don’t lose the two that are on there and get to try it out this year!
