(Malva neglecta)
Photo Courtesy of PBI/Gordon Corp. 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.
The leaves are lobed and can be confused with ground ivy. Mallow
leaves are attached to the stem at the back of a rounded leaf, where
ground ivy is attached in the center of the leaf and has a hairy upper
surface. Mallow does not spread from nodes on stems as does
ground ivy.
The flowers of common mallow are present from May to October.
The flowers are white to lavender and have dark violet veins. The
fruit resembles a cheese wheel. Mallow spreads by seed.
Immature Stage Common mallow is found throughout the United States.

Lambsquarter
(Chenopodium album)
Lambsquarter is an erect summer annual. The leaves of lambs-
quarter are lanceolate in shape, approximately 1 - 2 inches in length
and about 1 inch wide. The edges of the leaf are toothed and the
leaf tip is pointed. The leaves are covered with a white mealy subs-
tance, especially on the underside of the leaf. The leaves form alter-
nately on the stems. The root of lambsquarter is a branched taproot.
The flowers of lambsquarter are found in small green clusters and
lack petals. The clusters of flowers form in terminal spikes. Lambsqu-
arter spreads by black seeds that germinate in the late spring to early
summer.
Lambsquarter is found throughout Canada and the United States.

Integrated Pest Management Control Recommendations
Cultural Practices:
Lambsquarter is usually found in low-maintenance turf situations. Proper mowing will usually control lambsquarter due
to its upright growth habit. It establishes easier in spring-seeded cool-season turf that enters the summer in a thin state.
Lambsquarter will growth in both acidic and alkaline soils
Herbicide Use:
Make your postemergent herbicide application to lambsquarter that is actively growing and in the seedling to flower
stage of growth.
