    I have a problem with clover and other broadleaf weeds in my personal yard. I was wondering if there was something i could spray on st augustine and centipede right now to kill the weeds or do i need to wait for warmer weather to spray something. I live in central mississippi in zone 8a. Any advice or comments would be greatly appreciated.

    Atrazine is a good choice for shallow rooted broadleaf weeds(clover, chickweed, etc..) However it will not work for some of the deep rooted broadleafs(dandelion, dock, etc..) you will be safe with a "southern" formulation of say trimec. This would still have the 2,4,D with a much lower rate of dicamba and should work on the tap rooted broadleafs.

    Just be careful the Trimec formula does not contain MSMA

    2,4-d should be used with caution on floritam varieties of st aug.

    Weed-B-Gon works for me sprayed some two weeks ago....got dandelion and clover. Kinda surprised because temp was only in 80F range for a couple days but I used a lot of soap with it.

    here's neat trick for a homeowner buy some weed and feed for your type of lawn and a small pack of quicksilver(1 gal dose pak) spray the quicksilver and then apply the W&F.
    i would wait for spring to do this
