Trouble with my Pink Lady
My Pink Lady on G.11 rootstock did not fair well this last year. I got a few apples last winter. I planted it in 2010 and it did well for a couple of years. This last fall I noticed it wasn't dropping its leaves and assumed it was just slow to drop them. I actually stripped the leaves so the snow would not collect.
This spring it has not leafed out. I think now in retrospect it did not go dormant as it should and may have been killed in the early winter. The only thing green now is the trunk. It's putting out small branches down low.
Anyway, my question is regarding grafting to it. If the Pink Lady scion is not hardy enough for my winters should I cut it down to the graft and graft onto it there or could I get by with grafting 3 or 4 feet above the graft?. This would make it an interstem with Pink Lady.
