Two questions………
How much time should pass between applying a crabgrass killer (post emergent) and laying down new grass seed? How late into the season can grass be overseeded? I am anticipating an early fall, which will make a difference in timing. Just don't want to go to all the trouble (rent overseeder, purchase seed, water, etc.) if I am not going to be able to see the results early this fall and into next spring.
