Invigorating a graft
Last spring I grafted blackgold cherry onto 2 young sour cherries. In both cases I used the tip of what I believed was to become a dominant scaffold near but not at the top of the tree
Both took, but both put on almost no growth...(an inch or two from 2 buds on each scion) and each promptly covered itself in flower buds.
I have not had a graft placed like these fail to take off (if it took) but I also have grafted very little cherry. I would like to put these back into vegetative growth
I know I can work down from each, pruning away any bud shoots from the understock branch that seemed to become invigorated by the grafting. How far down can this influence?
On one tree there is a branch/shoot a foot directly above the branch I grafted to. I believe removing this will help? It is comparable in diameter (5/8") and clearly growing more aggressively. But it's removal will not give the graft apical dominance in regards the whole tree.
How effective is notching above for invigorating a branch. I have used the technique some on buds to force branching, but generally I have had poor results with it...either I am notching too early or not deeply enough. I can get a bud to throw a shoot, but rarely will it be a vigorous one.
Should I also be stripping the fruit buds/blooms from these grafts?
Any other tricks besides these and keeping full sun exposure?
