Had a company come out a few weeks ago and put down fertilizer mixed with crabgrass and weed control. It’s it okay to plant grass seed now (to fill in empty patches where moss once was)? Will the pesticides keep the seed from germinating?
The crabgrass preventer barrier on the soil should be gone by now. When you rough up the area prior to seeding, that will make it impossible for what’s left of the barrier to hinder the seed. Get that seed down right away!
