Patience is your best friend in this one. It sounds like you are a planner and he is a doer. In time he'll see how your plans and his hard work have combined to make a beautiful landscape TOGETHER. He may not see the details like you do, but he's working with you and that's good.
I was full blown crazy about
permaculture from the second I started learning about it around four years ago. My wife has humored me and my schemes for the last few years but slowly she started to see where my efforts have benefited
us. She is now as excited to get started with the online
PDC Geoff Lawton is doing this spring as I am.
I think
Permaculture is like one of those
Magic eye posters. Not everyone is going to see the hidden picture right away, and some never will. As long as you can enjoy it and he enjoys helping you AWESOME!
I've heard it said that the way to a man's heart is through his stomach. That may be the way to his mind too. You plan it, he plants it, and you and enjoy eating it together. He'll be hooked in no time.
Or you could just reward him with bacon when he does permie things. Bacon ALWAYS works.
