I'm building a raised bed garden in Brooklyn Park and need good gardening soil. Does anyone have any recommendations on good nurseries or businesses to get rich, clean topsoil? I will need enough that buying by the bag isn't economical. I bought a couple of yards from Lynde Nursery in Maple Grove last year but it was really bad - tons of weeds developed. I'm not sure if the compost wasn't cooked properly or what. Thx
