I just got a North Star cherry tree to replace a dead Montmorency. The Monty dying wasn’t a big surprise, it was a mail order tree that came in horrible shape so it got planted because the whole was already dug.
North Star is supposed to be both hardy and pretty dwarf on its own, yet I always see it on a rootstock. Is this just because it is just easier to propagate that way? I was thinking instead of throwing away a bunch of branches that need pruning that I would try air layering them. Has anybody planted a north star on its own roots?
