    Description

    • dense creeping plant with 3 – 14-inch-long stems and stalks tipped with three round leaflets marked with white V-shape on the upper leaflet surface
    • flowers are white to pink in color and sphere shaped (3/4 inch wide)
    • as flowers fade they dry out and produce a 1/4 inch long seedpod covered in a brown husk of spent petals

    Location

    • commonly grows in lawn areas

    Life Cycle

    • cool season perennial that germinates in the spring when temperatures reach 50°F; peak growth rate occurs between temperatures of 64-86°F
    • flower production occurs by mid-spring and continues through the rest of the growing season
    • as seeds ripen, flowers brown and droop downward and drop seeds 3 to 4 weeks after flower production

    IPM Recommendations

    • Hand-pull plants in planting beds prior to seed maturation.
    • Adjust fertilization program to include more nitrogen and less phosphorus when a soil test indicates low nitrogen and high phosphorus levels.
    • Apply an appropriate post-emergent herbicide directly to target weeds in planting beds; 2,4-D is not effective for control since it will only injure clover plants.
