    Description

    • low-growing (4 inches – 2 feet high) matted plant with deep branched taproot
    • coin-shaped leaves are 1/2 to 1-1/2 inches in diameter, have wavy margins and one deep lobe that extends to thick hairy stem
    • flowers are white to pink in color and have five petals and a funnel shape;
    • fruit is shaped like a cheese wheel and houses 10 to 12 seeds

    Location

    • commonly grows in planting beds and bare patches in lawn areas

    Life Cycle

    • common mallow can be an annual, biennial or perennial based on growing conditions
    • seeds germinate throughout the growing season with adequate moisture (mid-spring to early autumn)
    • flowers and fruit are produced from early summer to mid-fall and mature plants may stay green throughout winter

    IPM Recommendations

    • Effective control must target both aboveground and underground plant structures.
    • Hand-pull plants in planting beds prior to seed maturation.
    • Apply a mulch layer 3 inches deep on planting beds to reduce seed germination.
    • Maintain healthy, competitive desirable vegetation.
    • Apply an appropriate post-emergent broadleaf herbicide directly to target weeds.
