    I applied the Step 1 Scotts with crabgrass about 3 weeks ago and I noticed that I have some area's of crabgrass. Should I wait any longer to apply something else, or go for another form of crabgrass preventer or killer? Thanks!!

    Are you sure its crabgrass? Make sure it is before applying more chemicals.....

    Is "Step 1" a preemergent, or contact herbicide? If preemergent, then it is possible that the crabgrass was already growing, so it wouldn't kill it.

    I used the Step 1 Halts with feed. Not sure whether I need to go with a 2nd app, so use a liquid spot treatment.

    there was this landscaper who i used to be his sub for fert/weed control on his lawns. the guy was always calling me complaining about crabgrass. I'd go out to the lawns and find no crabgrass.

    One day i met him on a lawn that he had complained about the crabgrass. It was a bluegrass lawn. It had some tall fescue clumps. He said see...right cant see that crabgrass? On another lawn, a blue/rye mix, he had clumps of velvet grass that he was also calling crabgrass.

    I explained to him that crabgrass was a specific grass and that not all grasses that he didnt like was crabgrass, he said "if I dont like it, it is crabgrass!" I told him if my name was Tom and he was calling me Tony, good chance I wouldnt respond to him. Just because he calls tall fescue and/or velvet grass crabgrass, doesnt make it crabgrass and it wont respond, or be affected, by crabgrass controls.

    Are you sure you have crabgrass???

    I have a simple question: How COULD he have crabgrass? It isn't even May yet. You would have had to have had a heat lamp on the area since March. I am sure you have had recent frosts. It AIN"T crabgrass. Read a book.

    yeah turfscape, thats sort of what i was trying to say as well (was trying to be nice) alot of folks call anything that they dont like 'crabgrass'. fact is if he does have crabgrass, and he might, it would be just germinating about now. I'm in zone 6, as is new york (zones 6 & 5 i think new york is) bit early, i agree.
  8. If nyc stands for new york city, I don't it is crabgrass, since we in central va. haven't seen any germination yet, and the SOIL temps have only been high enough for 6 days!

    I am just starting to see crabgrass starting to germinate along concrete surfaces in bare areas. The seedlings are about 1/4 of an inch if that.
