Prostrate knotweed is a low-growing summer annual or perennial which is very competitive in compacted soils. It is often a problem along driveways, sidewalks, and beaten paths. The slender stems radiate from a central taproot and produce a tough mat-like growth. Leaves are dull, blue green, small, smooth and arranged alternately along the stem. This weed germinates with the first warm temperatures in the spring. Newly emerging seedlings are often mistaken for grasses in very early stages of development.
