I know I’m hijacking this thread but it looks like the OP is done.
I thought it didn’t matter how deep you planted the trees, provided the graft union is above the ground. Especially if the rootstock is prone to burr knot, as the trunk should form roots easily.
Have I doomed my crabapple by planting it too deep? It’s on MM111 rootstock which is prone to burr knot.
