Common mallow ranges from a winter annual to a perennial depending on the location. The spreading stems of mallow grow prostrate with leaves borne on long petioles. Common mallow grows from a thick straight tap root.
Weekly mowing and low mowing heights will help prevent infestations of mallow. Dense turf stands resist mallow invasion, so good turf management is key to controlling this weed.
