    If you miss the time frame to lay the crabgrass pre emergent what can be done to stop the pesty crabgrass. Besides spending hours picking each weed by hand.

    Postemergent. Didn't you learn that in your classes to get licensed? Or are ya a homeowner?

    I would think you still have time (even in ATL) to apply Dimension (pre- and post-emergent qualities) or Drive (post- and pre-).....

    In our area, we shoot to have all 1st rounds done by the end of April into 1st week in may. Then we turn around and start on round 2. I use drive, good product, but expensive!

    I heard that the ground temp should be 50 degrees or warmer for pre-emergents to work.
    A meat thermoeter will work for that.

    Or just look at the lilacs... they bloom when the ground temp gets to 50 degrees.

    Thats just for your region...........down in the south lilacs havent even though of blooming yet and we have had weeks of 80-90 degree weather already, crabgrass has already emerged and growing rampant, selective post emergent is the only hope now, way too late to apply a pre-m.
