Trifolium repens
broadleaf weedUSDA zones 3–10Active: spring, summer, fallLow-growing perennial with trifoliate leaves and white flower heads. Some homeowners embrace it; others view it as a weed. Fixes nitrogen in soil.
Three rounded leaflets, often with light chevron marking; creeping stolons; round white flower clusters.
Clover thrives in low-nitrogen soil. Regular fertilization favors turf over clover.
When: Apply nitrogen in early fall and late spring
Taller turf shades clover and reduces its vigor. Maintain 3-4 inch mowing height.
When: Ongoing throughout growing season
Pull clover patches including stolons. Most effective in small infestations.
When: Best when soil is moist in spring or fall
Effective systemic control of clover. Triclopyr is more reliable than 2,4-D for clover.
When: Apply in fall when clover is actively growing
Active ingredient: Triclopyr — e.g. Ortho Weed B Gon Chickweed Killer, Turflon Ester
