Knotweed (Polygonum Arenastrum)
Knotweed is an annual plant commonly found in infertile compacted soil. You'll notice this plant along driveways, sidewalks and heavy traffic areas. This is a low growing, mat-like structure. The stems, housing dull blue-green leaves, grow outward from a central taproot. You may notice purple flower clusters growing at the end of stems.
Facts About Knotweed:
- Knotweed can survive mowing, compacted soil, and drought conditions
- A Single plant can grow 3 to 4 feet in diameter
- Some people mistake knotweed for spotted spurge, the easiest way to tell the difference is break off the stem. Spurges contain a milky sap, knotweed does not.
Maintainng a healthy dense turfgrass lawn with proper watering, fertilizing, postemergent broadleaf weed control, and aeration will help in combating the growth of knotweed. It is not recommended to pull the plants, as tiny seeds can be spread and replanted. Granular fertilizers and liquid weed control applications will also help turfgrass dominate the lawn and prevent undesirable weeds.
