Johnsongrass Weed Control

Type: Grassy Weed
Trait: Erect
Life Cycle: Perennial

Appearance: Johnson grass is a coarse, clumping perennial grass. The blade of Johnson grass is flat and primarily hairless. The base of the plant is a reddish green color. On the leaves of the Johnson grass, there is a whitish midvein that snaps when the blade of grass is folded. Johnson grass has a large flower that is purplish brown. It blooms from May to October and has a pyramid shaped bloom.

Johnson Grass is particularly invasive and requires multiple strategies to kill it. You may need to use both preemergent and post emergent weed sprays along with other control methods. First, you want to develop a healthy, thick turf to discourage Johnson grass. This means you must aerate and overseed and add nutrients to your lawn. Mowing your grass often and watering as needed can also prevent Johnson grass from growing. A preemergent herbicide should be applied in the early spring and the late fall. Post emergent weed killers like glyphosate should be used to destroy Johnson grass.
