Weed Wednesday: Prostrate Knotweed
Happy Weed Wednesday! This week we want to talk about the earliest germinating summer annual weed, Prostrate Knotweed. Did you know this weed is considered a supreme indicator weed? What does that mean? This means that because of the conditions it successfully grows in, it sounds the alarm by telling you the health of the soil in that area. While this weed can sometimes be confused with Spotted Spurge or Purslane, this summer annual is commonly found in lawns, landscapes, and unmanaged areas.
It also can grow successfully in hard, compacted, unhealthy soil as well as in sidewalk edges, crevices, and other high-traffic areas. Since it is one of the earliest germinating summer annual weeds, it is able to establish itself in areas desirable grasses may grow. The root system is extremely fine and can even grow in the most extremely compacted soils. Being a low-growing weed, its stems are slim and wiry which can make this species hard to control since there is little surface area for weed controls to contact. Its leaves are typically oval shaped and it produces pink-white flowers and will reproduce with seeds.
Aeration helps break up compacted soil and limit future populations from seeding and growing. While this can be a very difficult weed to control, there are steps you can take before it grows and after it grows to make sure your lawn doesn’t fall prey to this aggressive weed. That’s where we come in.
