Green grasses add beauty to your lawn and your home overall.  However, if you have a problem with Crabgrass, it creates a problem that can be tricky to get rid of.  Crabgrass is an annual weed that favors compacted soil where the grass is in a thinned and weakened condition.  It is an annual weed that appears in the Spring and will last until the frost hits if not dealt with proper weed control

Crabgrass will germinate when the soil temperatures are between 55 and 65 degrees, about 3 inches below the surface.  So, unless you are prepared to dig up all the Crabgrass in your lawn and possibly have to start all over again when done, the best way to get rid of Crabgrass is, to begin with, a specific weed killer or herbicide.  After pulling Crabgrass, it will often grow back.  Below is information on what may work to eliminate your Crabgrass in a Bermuda lawn.

What Kills Crabgrass but not the Grass?

Since Crabgrass only grows in weak or think lawn areas, keeping your Bermuda grass thick and healthy is essential to prevent Crabgrass as much as possible.  When you do have a problem with Crabgrass, timing is important in treating it.  Many types of herbicides are on the market for killing Crabgrass on your lawn, and there are some varieties of herbicides that will destroy Crabgrass without harming your Bermuda grass.

Getting Rid of Crabgrass

Applying a pre-emergent crabgrass herbicide to your lawn in the early spring is best.  Spray or spread a liquid or granular pre-emergent herbicide over your lawn.  Re-apply the herbicide at intervals (dictated by the product manufacturer).  You should spot-treat the Crabgrass with a post-emergent herbicide listed as safe to us
