Common mallow is most frequently found in newly seeded lawns or lawns that are stressed and lack density. It can be an annual or biennial. Mallow has a deep taproot but can be easily pulled from moist soil.
The foliage resembles that of the geranium. The flowers of common mallow are pinkish-white and the fruits look like small, round cheeses.Control
Increasing turf density with proper mowing, fertilization, watering and other cultural practices can help in the control of this weed. For more information, see CSU Fact Sheet 7.202, Lawn care.
Post-emergent herbicides are only marginally effective. Triclopyr + clopyralid or triclopyr alone are suggested.
