A weed with leaves composed of three round leaflets at the top of a hairy leafstalk, 2 to 4 inches tall, grows in the lawn. White or pink-tinged flowers, 1/2 inch in size, bloom from June to September. Clover is a common perennial weed in lawns throughout the U.S. Although some people like it in a lawn, others consider it messy, or they don''t like the bees attracted to the flowers. The plant spreads and suffocates lawn grasses, resulting in large patches of clover. Because clover produces its own nitrogen, it thrives in lawns that are low in this plant nutrient.
Treat the lawn with a selective weed killer in the spring and early fall. Repeated treatments are often necessary.
