Weed leaves roll off of stems and grow up to 20 inches. Leaves are light green in color and have a white vein that runs the length. Leaves average 1/2" wide.
The flowerhead is green and also becomes purplish in color when mature. Individual florets have short, stiff bristles. One long spike, called an awn is at the tip. Flowerheads bloom from early summer to late fall spreading seeds which are brown in color.
Favoring moist soils, Echinochloa weeds adapt well to all kinds of soils and grows from 1 to 5 feet. They are often grown for cereal or animal feed purposes and are similar in appearance, often mistaken for one another and called barn yard grass. Collectively know as 'Common' barn-yard grass (Echinochloa crusgalli).
These grasses can be a nuisance and competitive. They have shallow roots can be pulled easily. Use a garden hoe if easier. In the spring and late fall use a pre-emergent herbicide to kill weed seeds.
Because most are summer grasses, apply strong efforts to eradicate in one growing season, grass will die off when fall frosting occurs. The second growing season will be much lighter. Using garden mulch will help control any seeds from sprouting.
