I'm adding fall overseeding to my services provided this year. I've already purchased a Plugr aerator and blueBird powerrake w/seeder attachment. My plan is to dethatch with the bluebird then aerate and then overseed/slice seed with the blue bird. Where should I get the seed? I've been dealing with Lesco for fertilizer and weed control, but never tried their seed. I'm looking to overseed with tall fescue. Any suggestions on seed or where to purchase? thanks.
