Ok guys I need to re-do some aeration work. I'm planning on putting some topsoil down mixed with alittle compost and spreading that and putting seed and penn mulch down. Do I need to scratch the soil too if I'm adding soil? I also got some 12-12-12 to put down on top of that. Im hoping for some good results since im adding soil but for some reason I can see that being pointless. What do you guys think?
