Hey all, I'm looking for some tips on finding properly aged compost for topdressing my lawn. I ordered some compost last year from a reputable mulch/compost supply place, and there was still quite a bit of un-decomposed material (small pieces of sticks, etc). When I spoke with them, they said that is the finest they screen their compost. Are there any good pointers (or sources in MN) on finding well aged compost? Thanks!
