I'm trying to explain permaculture and guilds to my 76 YO father-in-law. You know the type, plaid flannel old New England, with a we've always done that way, attitude. But his plum
trees and apricot trees look almost dead, or maybe even dead. I found a small plan for a plum guild, but wondered if anyone had any specific recommendations for an apricot in northern zone 5 almost into zone 4. We're in NH with plenty of space so that is not the constraint. Thank you for any ideas. Oh and I love flannel that wasn't a dig, just a general idea.
