    Can anyone help me identify this weed. My pre-m did not control this weed. It is popping up all over my yards.

    Warm season turf right? What pre did you sure in the fall? Rate? I tend to do my fall pre closer to November mainly because we get ties up mowing and with leaves.

    I've seen some small breakthroughs of Poa because of the warm winter we've had. I love all the chickweed and henbit I'm seeing in other lawns....keeps the phone ringing.

    Warm weather yes. What is your approach with chickweed this time of year?

    What you have is hairy bittercress. Its a winter annual Any 3-way will take care of it. Just make sure centipede or st aug aren't coming out of dormancy.

    Doesn't look like chickweed. Check if the flower has 5 split petals that look like 10

    I think Agrostis got it right, bittercress.
