White Clover

White Clover is a low-growing perennial broadleaf weed that spreads rapidly across lawns, pastures, and other turf areas. Though once intentionally planted for soil enrichment and grazing, it is often considered undesirable in home lawns today because it disrupts uniform turf appearance. Its creeping growth and ability to fix nitrogen allow it to thrive even in nutrient-poor soils where turfgrass struggles.

How to Identify

White Clover is easily identified by its smooth, three-leaflet arrangement. Each leaflet typically displays a white crescent-shaped mark. The plant produces creeping stolons (above-ground runners) that root at nodes, allowing it to spread horizontally. The flowers are small, white to pinkish-white, and clustered into round heads that appear from spring through fall. Leaves remain green even in low-nitrogen soils, giving patches a distinct color contrast within lawns.

Lifecycle

White Clover is a perennial that can survive for several years. It remains green and active in cool, moist weather but may thin during drought or heat stress. Its stolons root at multiple points, enabling it to regenerate quickly even after mowing or partial removal. It reproduces by both stolons and seed, ensuring persistence once established.

Prevention & Control

Clover thrives in low-nitrogen soils, so maintaining proper fertility is the first step to suppression. Apply a balanced fertilizer to encourage dense turfgrass competition. Hand-pulling small patches can be effective if roots and runners are removed completely. For larger infestations, selective broadleaf herbicides are effective and should be applied when clover is actively growing. Avoid overwatering or mowing too short, as both conditions favor clover spread.
