    Description

    • grass with upright growth (up to 2 feet tall) and flat blades that are hairy on both sides; ligules are membranous and ragged
    • bristle-like flower/seed heads with soft, feathery appearance
    • foliage changes color from green to purple to light brown as plant matures and available moisture declines in summer months

    Location

    • planting beds and other under-maintained areas including lawn areas

    Life Cycle

    • winter or summer annual; seedlings germinate in autumn or early spring
    • rapid growth with seed production by late spring

    IPM Recommendations

    • Hand-pull plants in planting beds prior to seed maturation.
    • Apply a mulch layer 3 inches deep on planting beds to reduce seed germination.
    • Apply an appropriate post-emergent herbicide directly to target weeds.
