How to Kill Broadleaf Weeds in Grass

One of the most common lawn problems is the growth of broadleaf weeds. Two examples of a broadleaf weed are clover and dandelion. However, there are many more. To properly treat the broadleaf weed, know what you are dealing with. If you cannot decipher which weed you are dealing with from the descriptions on the back of herbicides, contact your local county service. Once you know your weed, you can begin extermination.

Mow your grass to the proper height for the species. Each grass has preferred height range. In the summer, keep your grass at the higher end of the range to help prevent burnout. This will make the grass stronger and more likely to choke out broadleaf weeds.

Select a liquid herbicide specially formulated for your specific broadleaf weed problem. Apply the herbicide on actively growing weeds in the early spring and early fall. Mid-summer applications are discouraged. If necessary, apply on a day when the temperature is expected to stay below 80 degrees F.

Apply the herbicide at least 24 hours prior to mowing or watering your lawn. Do not apply if there is rain in the forecast.

Spray the herbicide directly over the broadleaf weed. The weed will absorb the herbicide through its leaves. Take care not to get herbicide on nearby flowers, bushes or trees. A second application may be required 20 to 30 days after the first application.

To protect your lawn from brown spots, do not apply a weed and grass killer. Make sure the herbicide is specifically made to attack only your broadleaf weed.
