Grassy & Broadleaf Weeds

Doveweed

Doveweed

Doveweed is a summer annual weed that usually germinates later in the growing season becoming problematic late in the summer. It closely resembles a grass but upon closer inspection, you will find that doveweed has stems that root at the nodes and purple flowers that appear on short stalks in clusters.
Fireweed

Fireweed

An erect summer annual with alternate, lanceolate leaves that have toothed margins. Fireweed is primarily a weed of pastures, abandoned fields, and some agronomic crops. Its leaves are elliptic to lanceolate in outline, approximately 2 to 8 inches long, and 1/2 to 1/2 inches wide. Their stems are erect, solid, and usually without hairs (though occasionally slightly hairy). Stems range from 1 1/3 to 10 feet in height. This weed grows in the thatch layer which is located above the pre-emergence controls, rendering such controls powerless to stop its growth. Soil deficiencies indicated by this weed include low calcium and phosphorous, high potassium and iron, and excess thatch. Correcting these deficiencies is the most effective way to prevent this weed from growing.
Goosegrass

Goosegrass

Goosegrass is a prostrate-growing summer annual that grows in a clump, with the base of the leaves being distinctively white to silver. The leaves are often folded and may be smooth or have a few hairs. It features a strong, extensive root system and readily invades hard, compacted soils found in high-traffic areas.
Ground Ivy

Ground Ivy

Ground ivy is an aromatic, perennial, evergreen creeper of the mint family. It thrives in shady, moist areas and can quickly crowd out turfgrass. Ground ivy creeps along the soil surface and forms roots where the leaves join the stem.
Henbit

Henbit

Henbit is a sparsely hairy winter annual with greenish to purplish, tender, square stems. It has a fibrous root system and can grow to a height of 16 inches. Henbit’s distinctive flowers are reddish purple that bloom in the spring with the flowers arranged in whorls in the upper leaves. This broadleaf weed reproduces by seed that germinate in the fall or winter. It can quickly invade thin turf areas especially where there is good soil moisture. Shade also encourages growth and are not affected by mowing.
Japanese Clover

Japanese Clover

Lespedeza, also known as Japanese clover, is a very common summer weed that can easily choke out thing turf. It is a mat-forming, wiry stemmed, prostrate, freely branched summer annual with dark green trifoliate leaves with three oblong, smooth leaflets. Lespedeza has a semi-woody taproot and grows close to the ground making it difficult to cut with a mower.
Johnsongrass

Johnsongrass

Johnsongrass, a coarse and generally clumping grass, is one of the most troublesome of perennial grasses that rapidly produces colonies. This grass reproduces by seed and underground stems.
Oxalis

Oxalis

Oxalis is an upright perennial with hairy stems. It has alternating leaves with heart-shaped lobes and bright yellow flowers with five petals. Its presence indicates very low calcium, high magnesium, and low humus.
Purple Nutsedge

Purple Nutsedge

Purple Nutsedge is a rapidly spreading perennial with flat leaves that are usually shorter than the flowering stem. They reproduce primarily by tubers. There is no pre-emergent control for nutsedge. Its presence indicates very low calcium, high potassium, high magnesium, low humus, low bacterial count and anaerobic soils. Yellow Nutsedge is a rapidly spreading perennial with flat leaves that are usually shorter than the flowering stem. They reproduce primarily by tubers. There is no pre-emergent control for nutsedge. Its presence indicates very low calcium, high potassium, high magnesium, low humus, low bacterial count and anaerobic soils.
Spurge

Spurge

Prostrate Spurge is a summer annual with freely branched hairy stems. It has opposite leaves, usually with a reddish spot. Its presence indicates low calcium, very high potassium, very high magnesium, high sodium, very high chlorine, and low humus levels.
Thistle

Thistle

Thistle is the common name of a group of flowering plants characterized by leaves with sharp prickles on the margins. Prickles often occur all over the plant – on surfaces such as those of the stem and flat parts of leaves. This very stubborn weed if not caught early on could take years to get rid of.
Wild Onion

Wild Onion

Wild onions are cool-season perennials with slender, hollow cylindrical leaves. Their presence indicates very low calcium, high magnesium, low humus and a low bacterial count.
Wild Strawberry

Wild Strawberry

Wild Strawberry is a common creeping plant that grows just about anywhere. It can grow up to six inches tall with hairy petioles, leaves split into three leaflets and has teeth on its edges. Creeping plants have runners, or stems, which grow sideways on the surface of the soil. As the runners grow, they send up new strawberry plants. Wild Strawberry usually spread by birds and other animals pooping seeds out in new places.
Wild Violet

Wild Violet

Wild violet is a low-growing clumping perennial with a dense, fibrous root system and heart shaped leaves that often cup toward the petiole to form a funnel shape. Wild violet is often considered difficult-to-control due to its aggressive growth, waxy leaves and resistance to most common herbicides. They are most often found in shaded, fertile sites and prefer moist soils.
Yellow Wood Sorrel

Yellow Wood Sorrel

Yellow Wood Sorrel, commonly called Oxalis or sour grass, is a vigorous weed. It is a summer annual that thrives in fertile, warm and moist soils and prefers shade. Easily confused with clover when not in flower, it is differentiated by its small yellow flowers, heart-shaped leaflets and lime-green to purple color.
