the free compost here is full of nutgrass seeds and nuts, not good.
this past year, I used cardboard to cover the nutgrass (from free compost), and topped it with compost, coffee grounds, and lawn clippings. When spring rolls back around, I'll add some chicken poo and fish emulsion. I probably have about an 8" layer of mulch down, will add more this weekend when I mow.
so far so good,
