My backyard has been taken over by crabgrass.. I would say about 30% of the grass in my backyard is crabgrass... I put down some pre-emergant weed control about 2 weeks ago but i think it was to late.. I went to home depot and all i could find for post emergent crabgrass is the spray bottle.. there is no way that will work.. is there anything i can do for this now or do i just have to wait till next spring to deal with it? Any help would be appreciated.. Also i have some kind of moss or somthing growing in my yard.. best i can describe it is a fuzzy moss looking area with really think sprouts coming up and what appears to be seeds on top. That description may not help but if so could anyone tell me what it might be and what to use to get rid of it.. Thanks guys.. Oh and i am in charlotte NC..
