So last year, I was messing around and tried grafting apple scions and T-buds. I tried T-budding onto some of the mature Enterprise branches and to some crabapple volunteers, and I also tried -- I think it's called slip grafting -- a scion to a root sucker/water sprout growing from the Enterprise root stock (Lopped off the water sprout, cut a vertical slit in it and wedged the scion in, lining up the bark cambium.)
None of the T-buds took, but to my surprise, the slip graft appears to have held. The scion grew last year, and this year, it looks like a whip growing up into the main tree's branches.
But now, the question -- is it possible to separate this water sprout from the main tree? It appears to be growing from the root almost two feet away from the base of the trunk.
If not, is it OK to let it grow like this?
Or should I just give myself a pat on the back and then chop it down?
