I just moved in to this home last fall. My lawn is pretty wrecked after this summer. I didn't water it much either which didn't help. I now have a great sprinkler system set up with timers for the front yard and I am ready to renovate. My plan is to aerate and then use an overseeding machine with vertical blades and a seed hopper. I will then topdress with topsoil/compost. My only question is whats the best grass seed I should be using. Right now my lawn is mostly some poor quality tall fescue with some clumps of grass that shouldn't really be there. I plan to pull that out. Whatever I buy I plan to buy enough to do 3 seasons of overseeding/aerating this fall/spring/next fall. Advice and suggestions?
