Successful grafts that stay dormant?
Over the last three years my pome fruit grafting has been pretty successful in the sense of grafts taking. But I've noticed some grafts that grow a bit the first year, but then seem to go dormant and stop leafing out or even growing new shoots. If I scratch their bark surface I can see bright green beneath, so I know they are still alive.
Is there any trick to get the buds to come alive? I've thought of trying gibberellic acid but can't find any information about it's use this way, or at what strength it would be used.
