The best defense against common lawn weeds in Florida is the cultivation of a healthy, vigorous lawn. Proper fertilization, mowing practices and irrigation techniques will produce a lawn that has the most potential to out-compete weeds. Supplemental weed control is often necessary, however, whether by hand-pulling, mowing before seedheads develop, or by careful herbicide application. Read labels when choosing a commercial herbicid--some weeds are chemically controlled before they appear, and others are controlled more effectively after they appear. Choosing the right turfgrass for a particular site and proper cultural practices will go a long way in preventing weed establishment in your lawn.

Broadleaf Weeds

Many broadleaf weeds affect Florida lawns including clovers, chickweed, Florida pusley, beggarweed, matchweed. Three-way herbicide chemicals are often needed to control broadleaf weeds once they are established in the lawn.

Grassy Weeds

Grassy weeds that invade Florida lawns include crabgrass, cogongrass, goosegrass, crowfootgrass, dallisgrass, bullgrass, smutgrass, annual bluegrass, alexandergrass and torpedograss. Commercial herbicides can be effective in eliminating grassy weed--some formulas also control young broadleaf weeds.

Sedge or Rush Weeds

Sedge or rush weeds include yellow and purple nutsedge (predominant weeds), globe, Texas sedge, annual sedge, water sedge, perennial kyllinga, path and beak rush. Chemical herbicides are available to control sedge and rush weeds, but many applications are often necessary due to the extensive underground growth of roots and tubers.
