Hi all. Question for you experts: I live in south west ohio. I planted a new lawn last year (early Nov.), and did it a little late since we moved into our house late. Anyway, currently its about 50/50 grass to weed ratio. I definitely plan on overseeding this year (mid Sept), but was wondering if you would recommend to weed and feed first? i orginally planted tall fescue and plan on overseed with the same. Also, if i rent a slit seeder, is it really necessary to aerate as well? Thanks for the help!
