Root pruning: YES Withhold nitrogen: YES Minimize dormant pruning, do some summer pruning (but don't remove fruit): YES Use Apogee: YES Over-crop: YES maybe, but use NAA and/or Ethrel to promote return bloom development Use B.9 rootstock (as opposed to M.9): YES Make sure you have enough variety to pollinate: YES
I found Morren's Jonagored Supra (Willow Drive) grown on B.9 rootstock to be a very nice Jonagold strain. Good crops without too many large fruit. Still have to watch biennial bearing. I would plant that strain in a heartbeat if I want Jonagold. Did you hear New England Apple Association is going to brand Jonagold apples grown in New England? Not sure, however, what they are calling it? Any other ideas out there?
