I'm in South Carolina Columbia area, I'm needing to fill some low spots prior to spot seeding with centipede. What should I use? I've bought those bags of "topsoil" before and they had so much bark and "stuff" in them nothing would grow. Areas of my lawn are clay and others sand. I understand that you don't want to use the wrong kind of sand.. but I don't remember which kind to avoid.. Yes I've tried googling...
Any clues?
