Most fruit tree suckers are from the root stock and if used as root stock for new trees, that is quite possible, if the root stock used was appropriate for the mother tree. Al

Thanks, I have got the tree from a really good nursery so that should not be a problem. I never have grafted - is it difficult?

First time grafting, follow the rules and do at least twice as many as you need to allow for those that do not take. Al

Thanks! I really have got enough suckers to do three times as much.
