This is my 3rd year starting mulberries from seed. I'm using the root maker system...starting in RM18s, then 1 gal, then 3 gal. All the plants seem to want to take bush-form with more growth on branches than the leader. I want them in tall tree-form, so I prune the branches but they just keep coming. I'm starting to wonder if the RM root pruning is causing this? If so, not sure what options I have since direct seeding hasn't worked due to inability to frequently water them and I don't have any containers tall enough for a deep tap root.
Any advice is appreciated and thanks in advance
