Needs to be a solution for those of us who are housebound and/or rural. Online is our only option.

No till is an option though. I use cardboard underneath the layers on top (I have an acre no till garden, 8 years in). Tilling can mess up the mycelium. You will need to work on any perennial roots though for some years, but would need to with tilling anyway. You don't need to mix in amendments. Layering and having the right plants nearby works. Nature is smart :)

tip - Witch hazel makes terrific deodorant- and a $2 bottle i use is still half full after years (barely use any per use and its good for days, tho ymmv).
