OK, sounds like air layering is the way to go. I'd never heard of that before, so thanks for the info! Bummed that I won't get any fruit this year, though. The trunks are 1.5-2.5" at the areas where I would air layer. Do you mean that instead of using a little plastic bottle/cup, I would wrap the trunk with a 2 gallon pot? I don't think the shape of any of them so far are real great, but I'm still trying to wrap my head around which branches to prune. For every branch that I prune, will I get 2 branches that grow at that area? I"m not sure about dormant nodes near the base either. I'm assuming that these would look like something that has the potential to come alive, and I"m not seeing that near the base. Nothing that looks like it has the beginnings of a bud. Or does it just look like a little dead flat area until it starts to bud? I've attached pictures of them in case anyone has any more tips.
After I cut off the airlayers and plant them, would I need to continue pinching off the fruit next year also to encourage root growth? Maybe let them start fruiting in 2018?
