A related species, purple nutsedge, is especially Yellow Nutsedge prevalent in the Southeast. YYellowellow NNuuAPPEARANCE: Though it resembles a grass, yellow nutsedge is actually a sedge. Its coarse, light green leaves grow upright from triangular stems. Seed heads appear from July to October. GROWTH: Reproduces mainly from underground tubers; however, they can reproduce by seeds and underground stems. Tubers store food and are drought tolerant. Yellow nutsedge grows vigorously in summer, especially under moist conditions; primarily troublesome in closely mowed lawns.

RANGE: BlackBlaBlackck Medic MeMe Throughout the United States. APPEARANCE: With its three leafl et, cloverlike leaves, this legume is often confused with white clover. Low growing, with trailing, slightly hairy stems, it produces clusters of small, bright yellow fl owers in late spring to early summer.

GROWTH: Black medic is common in lawns from May through September. It is especially prevalent in dry soils where turf is spotty and in high-phosphorus soils. Though an annual, it can be as persistent as a perennial. Contact Loyalty Lawncare Today ( 636)-498-0100 www.loyaltylawncare.com Where Personal Service is Always in Season....

Contact Loyalty Lawncare Today ( 636)498-0100 www.loyaltylawncare.com Where Personal Service is Always in Season.... L A W N W EEDS RANGE: Found throughout the United States except in the Rocky Mountains. APPEARANCE: Common chickweed is a shallow Common Chickweed fi brous rooted winter annual which CommonCommongrows in moist shaded areas. The leaves are small, smooth, pointed at the tip and elliptic in shape. They are opposite on branching creep- ing stems, which root at the nodes. Chickweed adapts well to different mowing heights. The fl owers of common chickweed are white small star like with 5 notched petals. Common chickweed spreads by seed. GROWTH: Common Chickweed thrives in cool, moist areas. Growing conditions can be made less favor- able by lightening the soil or other- wise improving drainage, especially in shady areas. Heavy, constant shade should be lightened as well where possible. Shady areas should be planted with turfgrass species which do well in the shade and which will provide maximum competition to weed species which invade shady areas.

L A W N W EEDS RANGE: Goosegrass is found in the United States from the transition zone south APPEARANCE: Goosegrass is a prostrate- Goose Grass growing summer annual. The leaves GooseGoose GGrr are folded in the bud. Goosegrass grows in a clump with the base of the leaves being distinctively white to silver in color.

GROWTH: Goosegrass is highly competitive during hot summers, and can out- compete desirable grasses where soil is compacted. Core aeration should be provided to improve soil conditions for desirable grasses. Single plants can be physically removed with a knife. Do not seed when soil and weather conditions are appropriate for the germination of goosegrass (60 to 65 degrees F). A slightly raised mowing height may help prevent the establishment of crabgrass by providing shade from sunlight.
