Common knotweed, also known as prostrate knotweed, is a low-growing plant, only ever growing as tall as four inches. When the plant germinates in late winter or early spring, it will grow upright. However, as the plant matures, its many stems creep outward from the plant’s node, becoming prostrate and growing up to 3 or 4 feet in diameter. The stems are bright green in color, hairless, and turn reddish or purplish towards the center of the node, similar to crabgrass. The leaves are hairless, slender, pointed, and oblong in shape. This plant can produce tiny flowers from spring to fall, which are white, green, or pink in color.

Common knotweed can germinate from late winter to spring, depending on when there is enough moisture. This plant is difficult to detect when young, as the seedling’s leaves can blend in with most turfgrasses. Knotweed becomes more distinguishable as it matures towards the summer. This plant thrives in highly compacted soil, so look in areas like against sidewalks, in cracks in pavement, or even in lawns where high foot traffic has condensed the earth.

To get rid of prostrate knotweed growing on your property, you’ll need to use a post-emergent herbicide like MSM Turf. MSM Turf is a dry flowable herbicide that contains the active ingredient Metsulfuron Methyl. Mix this product with enough water, and it can be applied over warm-season grasses as well as a few cool-season grasses. You’ll apply this product at a rate of 0.5 to 1.0 ounce per acre of treatment area. If you’re dealing with knotweed growing from cracks and crevices in pavement, then you can use a product like Eraser. Eraser is a non-selective weed killer that’s made with the active ingredient glyphosate. Glyphosate is a very powerful ingredient, however, it is non-selective, meaning the product will affect and kill any plant it is applied to. This makes it great for treating isolated spots like within pavement, but it’s generally not recommended for lawns as it will severely damage or kill your grass if you’re not careful. Use Eraser at a rate of 2.5 fluid ounces per gallon of water. This will treat up to 300 square feet of treatment area.

Regardless of which herbicide you choose, we recommend you use a 1 or 1.5-gallon handheld pump sprayer to make mixing and application quick and easy. With low pressure, spray weeds directly and use a fan setting to thoroughly coat the leaves’ surface. Spray the weed to the point of wet, but not runoff.

If you’re concerned about stopping the growth of knotweed on your lawn, then consider laying down a pre-emergent herbicide with prodiamine. We recommend you use a product like Barricade. When applied properly, Barricade will form a chemical barrier that will stop weed seeds from sprouting. You’ll use between 1.5 to 4 pounds of Barricade per 1,000 square feet of treatment area depending on your turf type. Once the product is fully applied, water it in.
