I have a bunch of volunteers popping up under my apple trees. I dug up a few and planted them separately so that I can try some grafting in the future. Right now they are about half the diameter of a pencil, so probably too small to graft. Maybe I'll try budding them in the summer if they are big enough by then.
Anyway, the small rootstocks are starting to leaf out. Should I remove some of the remaining buds in order to promote "trunk" growth or does it not matter?
