Cheeseweed mallow is a weed found in much of the United States from Texas to California and Hawaii, as well as Canada and Australia, where it appears in lawns, gardens, croplands and along roadsides. It does not appear on any state or national invasive species lists. The weed can be poisonous to mammals, including cattle, and cause lower quality eggs if eaten by poultry. It can reduce crop yield and interfere with harvesting. The plant quickly develops a strong root, making it difficult to remove. Cultivation by hoeing will help eliminate the plants, hand removal of single plants or herbicide usage.
