Thanks for posting those links. I look forward to checking them all out. Yeah, wood is added to my shredded leaves because we always have fallen oak tree branches. I hadn't seen a lot on DG about permaculture and had even requested a forum but got no response. The only other person to show an interest over at DG is now gone. I did purchase the 2-volume set of Edible Forest Gardens for DD as she does sustainable gardening at the moment which I know is a little different but have never read the volumes. Might be on my summer reading list along with some of the others. Thanks!
