I had previously overseeding and than was watering 3X a day for the new seed, but i think all the watering really helped the weeds go crazy and just in the past couple weeds they have srung up everywhere!...and I mean everywhere! they are starting to take over the whole lawn so i really need to do something asap. Whats the best stuff to use that will kill the weeds but not that grass. I need something that I can spread with my broadcaster...pellet type stuff. Not spray b/c it would take way to long to spray the whole lawn. Thanks! PS - Hopefully something I can get at Home Depot.
