Ok guys, this is my second year at my house. I would like to try and get my lawn to a better state this year. Last year I tried over seeding and filling a lot of dead spots left from the previous year, yet my lawn was eventually about 65% crabgrass. I've been doing some reading and apparently I can't put down a pre-emergent for the crabgrass AND still seed fairly soon after. Can anyone offer some advice to try and get my lawn nice and green this year? Should I just seed and fertilize all my bare spots and hope it prevents the crabgrass from blooming?
