I recently top seeded a large area of shaded yard where grass was very sparse during last years growing season. Now I wish I had areated (pull behind plug type) prior to seeding. If I areate now, should I re-seed, or will the seed on the ground be ok. Also, can someone tell me why people believe that their yard needs to be rolled at scheduled periods. Wouldn't compacting the soil be a bad thing?? It seems counterproductive to areating. Thanks in advance for your thoughts.
