    I am not near your state. But I would say time is right for pre-emergent crabgrass control, if your soil temp is 52. That should mean you air temps have hit around 70 a few times, right? If crabgrass has been a problem be sure to use the maximum rate allowed on the bag. And be sure and do a second application about 6 to 8 weeks later. Don't be surprised if you need some broadleaf weed control before long also. Normal to need more broadleaf weed control later in the season also.

    Ok so I am just starting summer now. I Switched from Pre-M to Dimension this year. It has done a much better job imo than Pre-M last 2 years, but I still have some small spots of Crabgrass and the occasional other nuisance weed or grass. Can you tell me what I can use now to combat the growing nuisances that will not hurt my Bermuda? I need to fertilize again so if its a mixture that will work also.

    Thanks.

    Ok so back again this season. About 3 weeks ago I put down some Dimension crab grass preventer Now I have some weeds popping up that I want to know if I can go after them now. My bermuda is still dormant and hasn't started greening up next to driveway or bricks yet. I was planning on using Ortho Weed B Gon Max for Sothern Lawns Looks like main ingredient is 2,4-D others are listed on that page.

    I have some dandelions along with the following weeds that I am unsure of the name.
    Weed #1 Henbit ??

    Weed #2

    Second weed is hairy bittercress. The Ortho product is a good choice for those.

    The weedy grass is poa annua...more difficult problem. I am not from bermuda country so you will have to relie on more local advice for that problem.

    blake711, its too late to get rid of the poa annua. itll die off on its own when temps start warming and bermuda will replace it. im fromgeorgia it sticks around through mid april if you have it but it will die. to prevent next yr use a pre-emergent september and maybe oct depending on your weather. im not familiar with

    Since you are in Tulsa, you are north of me. I just quit spraying Glyphosate in dormant bermuda on large areas last week. I might still spot spray it in certain areas(still dormant) but probably only this week. After that, no more using it for me unless it is used as a non-selective. Bermuda is beginning to green a little in thin areas and close to concrete and brick. You are probably running about a week behind me so you still have time...but not much. The little flower weed is called "Star of Bethlehem". 3-way won't kill it but R-Up will. If not killed it will go dormant through summer only to return next spring. 3-way will also do nothing for the annual bluegrass(poa annua) and yes, it will die with the heat but R-Up will take it out too if caught in time.

    If you mix according to directions on the label, a misting of your herbicide of choice should be all it takes.
