Is There Nutsedge in my Lawn?

How to Identify & Control


At first it looks like grass, but soon it will grow faster and sprout flowers and you’ll know you have weeds—most likely you have nutsedge in the lawn. Learn more about how to identify this weed and help prevent and control it.

What is Nutsedge

Also known as nutgrass, nutsedge is a perennial weed, so it will most likely return year after year if not properly removed. How do you know if it’s nutsedge in your lawn?

  • Shows up in the summer
  • Triangular-shaped stem
  • Long blade with leaves at the end
  • Yellow, purple, or dark red flowers

One distinguishable feature you won’t see right away is the intricate root system that reaches up to 14 inches deep. Root tubers also grow horizontally and emerge with a new sedge plant. This makes it harder to control, especially by hand.

Controlling Nutsedge in the Lawn

Like many weeds, nutsedge can take over your lawn if not controlled. In addition to spreading through roots, the seeds spread in the wind and rain.

Nutsedge prefers moist conditions—whether from poor drainage, over-watering, or excess rainfall. It will grow in dry conditions as well if there’s less competition from other grass. This brings us to one way of controlling this weed: a healthy lawn. Proper mowing, fertilization, aerating, and watering helps create a thicker, healthy lawn that prevents any weeds from growing.
