I had the lawn thatched and overseeded & fertilized 3 weeks ago, than the following week I put down more seed & starter fertilizer again (2 weeks ago) as I felt the guy didn't put down enough seed initially. He told me to wait like a month before putting down any weed killer, but I am having a lot of weeds coming in right now, so I want to know if it's ok to do it sooner. Alot of the bare spots have already sprouted. Some more than other and some none at all. And there is still a good amount of seed I can see in some areas. I have a bag of Scotts "Weed and feed"...will this kill the seed that hasnt germinated yet? Or is it too late for that seed to germinate anyway? I don't know if it kinda dies after a couple weeks of sitting on top of the soil or grass. I have been watering it 3 times a day (IG sprinklers) keeping everything wet, and we have also had a lot of rain too, so that hasnt been a problem. Just all these darned weeds I want to kill!
