The lawn I need to over-seed was planted last fall. It is consistently thin all over. The soil isn't too compacted. I sprayed for weeds a few weeks back and it killed most of them along with some of the weaker grass. I have called around and cannot find a power seeder to rent. Any ideas? How much success would I have by aerating, casting seed, and rolling it in? Also would mulch mowing afterwards be a good way to hold some moisture around the new seeds between watering? I would also apply a starter fertilizer. I hate to delay over-seeding until fall but maybe that's best. We do have a few more months of moderate weather so seeds should germinate well if I do it now. This is all new to me so I didn't apply pre-emergent in time to keep the weeds down. Any advice would be appreciated!
