How deep should I bury the graft union?
I am waiting for grafted roses I ordered for this year to arraive in the next couple of weeks. I would like them to eventually go own root. How deep should I bury the graft unions?
I understand that for my zone, which is 6b, the general guideline is to lightly bury the graft union, but that is for protecting the unions, notf for helping the roses go ownroot . I think I would just bury the union deep, say, by 6 inches of soil. Does this make sense? Would I harm the roses?
One of my source is Palatine, and the multflora rootstock they use does not do well in my soil.
Many thanks in advance.
