• Common Mallow

  Common mallow most often establishes along culverts, fencelines and near foundations. Common mallow forms a clump whorled branches that do not root where they touch the ground.

• Black Medic

  Black medic is a low-growing creeping weed that is well adapted to many lawn situations. In particular, black medic can be an indication of low soil nitrogen. It is most common to find medic in full sun , low maintenance situations. Black medic and white clover grow in similar situation and are often found growing together.

• Shepherd's Purse

  Shepherd's purse is a winter annual with a basal rosette of lobed leaves and a long flowering stalk. Leaves become more deeply lobed as they mature. Due to extremely long-lived seeds and an affinity for disturbed soil, it is most often a weed of new seedings established between mid-August and the end of September.

• Bacterial Wilt

  Bacterial wilt is characterized by tiny red-copper-colored spots first appearing about the size of a dime. As more plants die, spots become larger. Small, yellow leaf spots, streaked tan to dark brown spots, dark green, water soaked lesions, shriveled blue to dark green leaves, and yellow elongated leaves are all symptoms that have been associated with bacterial wilt.

• Yellow Nutsedge

  Yellow nutsedge is a persistent perennial weed of poorly drained soils. Yellow nutsedge is grass-like in its appearance with parallel leaf veination. The stem of nutsedge is triangular with leaves coming off each corner (three-ranked).

• Waitea Patch

  Waitea patch is an emerging problem on annual bluegrass in Michigan. Symptoms typically begin as thin yellow rings, ranging from a few inches to a 1 ft (10 cm to 0.3 m).

• Annual Bluegrass

  Annual bluegrass is unique among weeds. There is probably no other weed that is so widely adapted to variations in mowing height, site conditions and cultural practices.

• Quackgrass

  Quackgrass is a common grassy weed of turfed areas. Quackgrass is a perennial and can often be spotted by its dull blue-green appearance. Because quackgrass spreads by rhizomes (underground stems) it responds very well to cultivation practices. It is common to have quackgrass contamination in unscreened topsoil. Each rhizome section has the ability to produce a new plant.

• Mouseear Chickweed

  Mouseear chickweed is a low-growing perennial that can tolerate extremely low mowing heights (even at greens height). It can tolerate a wide variety of soil and growing conditions. The leaves of mouseear chickweed are typically very thick, dark green and covered with hairs.

• Common Chickweed

  Primarily a winter annual, common chickweed is frequently found growing in the mulch skirts of shade trees. In general, common chickweed prefers shaded sites with moist soils. The vegetation forms mounds that are 3-7 inches tall. The delicate white-to-pink flowers appear early in the spring. Plants can persist in protected areas well after flowering.

• Broadleaf Plantain

  Broadleaf plantain is probably the second most common broadleaf weed of turf after dandelion. It is extremely well adapted to most sites including dry or wet conditions, heavy soils and very low mowing heights.

• Yellow Patch

  Yellow patch, also known as cool season brown-patch, is a Rhizoctonia pathogen similar to that of brown patch.

• White Clover

  White clover is one of the most common weeds of turfgrass. It is frequently included on lists of difficult-to-control weeds. White clover, as with all legumes, has the ability to survive under low soil nitrogen conditions. It can be identified by the three leaflets attached to one petiole.

• Wild Strawberry

  Wild strawberry is a trifoliate (three leaflets) weed that spreads by aggressive stolons. The leaves and fruit of wild strawberry are smaller than that of its cultivated cousin. Wild strawberry is usually found in low maintenance areas and prefers well-drained soils.

• Foliar Anthracnose

  Anthracnose can occur as both a foliar infecting and crown infecting disease.

• Buckhorn Plantain

  Buckhorn plantain is a narrow-leaved perennial that forms a rosette. The 3-10 inch long leaves are less than 1 inch wide and arise from a thick, shallow tap root. Buckhorn plantain is very common in maintained turf but will also survive in meadows and waste areas.

• Rough Bluegrass

  Rough bluegrass is often used to overseed dormant warm-season turfgrasses. Overseeding typically occurs in the fall to provide a playing surface throughout the winter months.

• Carolina Geranium

  Carolina geranium is an uncommon weed of low or no-maintenance areas such as fence rows. The leaf shape is very similar to common mallow, except that the leaves are more finely dissected. Pink, inconspicuous flowers are produced within the canopy. Plants typically do not persist after flowering.

• Common Purslane

  Common purslane is a mat-forming summer annual that thrives in all soil types. Common purslane has multi-branched red stems with thick fleshy leaves that cluster at the end of the branches.

• Rust

  Rust diseases are characterized by yellow to dark brown urediospore infestations that, from a distance, make turf stands appear orange or yellow.
