Chelle, I felt sad about the loss of your trees. They were breathtakingly tall! A lot of work, you will have to keep us posted.
The school property behind our house (a small woodland) had tall (not like yours though) Ash trees when we moved in, then about 10 years ago they began to fall. So sad. Now we have Maples growing there. Even though it isn't my property I have begun to make a small part of it my own woodland garden ... I have cleared the wood from my small area, but now after finding out about Hugelkultur beds (thanks to you!) I will be moving some of it back.
I'd love to try to do a small buried Hugelkultur bed for my veg. garden .... but it would be iffy since the veg garden is right next to my house. Lots of things buried there to go very deep at all..
