Weed Identification

Broadleaf Plantain

Listed below are the most common Arkansas Weeds and descriptions of the plant, along with how we can help eradicate them. Broadleaf plantain is a perennial broadleaf plant that infrequently behaves as an annual or biennial. Leaves are broadly lance shaped to egg shaped, hairless or sparsely short haired. Roughly 2 to 7 inches (5–18 cm) long, leaves have five to seven prominent parallel veins from the base. Roots are fibrous and shallow. Seeds are tiny 1/50 to 1/25 of an inch (0.5–1 mm) long, oval to irregularly angled, or triangular, orange to black and dull, with a finely textured surface and it reproduces by seed. B&A recommends a Post Emergent with Prodiamine in the Spring to help control broadleaf.

Poa Annua – Annual Bluegrass

Annual bluegrass, Poa annua, is one of the most common weeds of residential and commercial turfgrass, ornamental plantings, and gardens in the United States. Annual bluegrass is a cool-season grass weed that starts germinating in late summer or fall as soil temperatures fall below 70°F. It continues to germinate throughout winter, allowing several flushes of germination at any one site throughout the season. Annual bluegrass grows 6 to 8 inches high when left unmowed. It has light green flattened stems that are bent at the base and often rooted at the lower stem joint. Leaf blades are often crinkled part way down and vary from 1 to 3 inches long with typical Poa boat-shaped leaf tips. Annual bluegrass can be a major weed problem in home lawns and is a continual nuisance for turf and landscape managers. Because it is a grass weed growing in turfgrass, selectively removing it is very challenging. B&A recommends a Pre-Emergent with Prodiamine and a Post-Emergent with foramsulfuron to control. Once the weather warms up, Poa Annua will die off.

Dallisgrass

Dallisgrass, Paspalum dilatatum, is a tufted perennial grass that was introduced into the United States from Uruguay and Argentina. It is now naturalized in much of the southern United States. Dallisgrass is a coarse-textured grass that grows in a clump and slowly increases in diameter as its shallow, underground stems (short rhizomes) grow outward. The rhizomes have short internodes (the length of stem between the joints) that look like concentric rings on its surface. The leaf blades of dallisgrass are fairly wide (1/4–1/2 inch) compared to desirable thinner turf grasses. If left unmowed, blades will grow 4 to 10 inches long. Dallisgrass produces abundant amounts of seed, which are its primary means of dispersal. Water, lawn mowers, and humans or pets spread the seed to new places. Seeds usually germinate in spring and summer when soil temperatures are in the 60° to 65°F range and grow to form new clumps. This is one of the hardest turf grassy weeds to control. B&A recommends several special treatments to control Dallisgrass.

Henbit

Henbit is a widespread winter annual or sometimes biennial broadleaf plant. Mature plants can grow to 1.3 feet (0.4 m) tall. Stems are square in cross-section and often branch near the base. Leaves are roughly 2/5 to 1 inch (1–2.5 cm) long, sparsely hairy, and broadly egg shaped or heart shaped to nearly round. Middle and upper leaves are stalkless with lobed to truncate bases, a rounded tip, and a round-toothed to weakly lobed edge. It is reproduced by seeds or nutlets that are brown, tiny, and triangular in cross-section and have a rounded to squared tip and a long tapering base. B&A recommends using a Post-Emergent with Simazine. Apply early before the weeds get big.

Buckhorn Plantain

Buckhorn plantain is an annual, biennial, or perennial broadleaf plant. Leaves are football shaped; about 3 to 10 inches (8–25 cm) long, and usually have short hairs (or occasionally long hairs). The leaves spiral around a very short stem, clustering around the base of plant. Flower stalks grow up to roughly to 2-1/2 feet (80 cm) tall. Flowering takes place from April through August. Flower heads consist of leafless, slender spikes of inconspicuous flowers clustered densely along an upright flowering head, usually 4/5 to 3 inches (2–8 cm) long, excluding the stalk. B&A recommends using a three-way herbicide in the Fall.

Sometimes, even after receiving an evenly applied Pre or Post-Emergent, weeds will still live. There could be many underlying reasons hindering your turf. B&A will do investigative work to find out what is keeping your lawn from being its best.
