our compost isn't ready yet...I just found some "rich topsoil" on craigslist but I don't need a big truck load! our raised beds took all we had too. I will have to remember the peat moss, my worms love it too...tksWifezilla said:I used aged compost in the bottom and then added some top soil and peat moss. I have had to buy dirt this year because of all the growing beds I added.
