All this sounds great. Actually, I’ll be building up beds in my tiered (terraced?) back yard and need a lot of fill. I was thinking about filling the bottom with the wood shavings and leaves (we have a lot of leaves available from a variety of trees on the property). This is just the beginning of a very long process (probably 5 to 10 years to complete); I just don’t want to lose anything useable I have for free! Thanks for the links! Off to read… -jj the aa.
