- Treat your Bermuda grass with water to keep it healthy. Fertilizing it properly will discourage any weeds that may attempt to grow. Be sure that you water it regularly after it is fertilized. If you live in a climate that is extremely hot, you should water it twice, once in the morning and another when the sun sets. Keep performing these actions and once the grass is growing healthy, you can limit watering to once a day.
- Treat your Bermuda grass with herbicide chemicals. There are available herbicide chemicals that kill weeds and prevent their growth. Crabgrass is one of the worst weeds that can affect Bermuda grass so a herbicide may be necessary to kill it. Herbicide should be placed on the grass in the spring if you want it to work properly. Protect any flowers or plants that may be near the grass you are treating because herbicides can kill your plants. These chemicals can be purchased from a local hardware store such as Home Depot. The chemical is sprayed directly in the grass. Be sure the chemical is suitable for your Bermuda grass and your climate because there are many types of chemicals designed for all types of grass. An associate at the hardware store can assist you with the type of treatment needed for your Bermuda grass.
- Treat your Bermuda grass with a pre-emergent chemical. To effectively rid your lawn of weeds, you must kill the seeds and prevent the weeds from germinating. A pre-emergent chemical keeps the weed from germinating and should be applied before the weed's growth period. This is usually done around the second week in March and the second week in September. Be sure to water the soil properly after applying the chemical. The soil must be moist for the pre-emergent to be effective. When purchasing the pre-emergent, seek the advice of a professional if you aren't sure which chemical works best.
