Clover is a common weed found in a multitude of lawns across North America. The small plants are re-seeding winter annuals. Clover can easily overtake a lawn and give it an uneven appearance. Clover normally stands out against a lawn because it is a far deeper green then common lawn grasses. Clover can be killed if a diligent regiment is followed.
Apply a selective broad-leaf herbicide in the late spring to early summer. Follow the instructions on the herbicide's label for application. Mix in a hand-held pump garden sprayer or a backpack garden sprayer for best results. Apply on a calm day when there is not a great deal of wind. Make sure there is no rain in the forecast for at least 48 hours after application. More then one application will be required for complete control of the clover.
Replant grass seed in the areas where the clover once stood. It is important to replant the area so more clover does not take hold and grow. A strong thick lawn is the best defense against clover invasion.
Mow the grass regularly at a height of 2 inches to prevent clover growth. Mowing the grass helps the lawn grow thicker and prevents clover growth. Frequent mowing also helps prevent the clover from building seed heads to re-seed.
Pull small patches of clover by hand. Discard the plants in a plastic bag promptly.
