Whenever I have put in lawns, usually smaller ones, I spread peat moss over the top instead of straw. No mess to clean up weeks later and no weed seeds popping up. My question is; how many bales would you need for 5500 sq feet of lawn? Or, how much area does one bale cover? I don't know much about it, but Ive heard that hay and straw are 2 different things. Is that true, and isn't there one that has seeds that germintae all over the place after you water your lawn in?
