Nutsedge: Why It Keeps Coming Back

You Mow It Friday and It’s Standing Taller by Sunday

Nutsedge, or nutgrass as most people around here call it, is the weed that makes homeowners think their weed killer is defective. You spray it, it browns off, and a few weeks later it is back in the same place.

The reason is underground. Nutsedge is not a grass at all. It is a sedge, and it stores energy in small tubers called nutlets sitting several inches down in the soil. One plant can put out dozens of them. Kill the top and the nutlets send up another.

It also grows faster than bermuda, so it stands above the lawn within a day or two of a cut, which is why it always looks worst right after you mow. It favors wet, compacted ground, so a patch of nutsedge is often telling you something about drainage as well.

We Treat Nutsedge. It takes a sedge-specific product and repeat timing to exhaust the nutlets. That is built into our spray program.

How to Know It’s Nutsedge

It gets mistaken for grass constantly, and the products that kill grassy weeds do not touch it.

Roll the Stem in Your Fingers

Sedge stems are solid and triangular. Grass stems are round and hollow. That is the fastest identification there is, and it is definitive.

A Glossy, Yellow-Green Color

Lighter and shinier than bermuda, which is why a patch stands out even when it is cut to the same height.

Leaves in Threes

Nutsedge leaves come off the stem in three ranks. Grass leaves alternate in two.

Faster Than Everything Around It

If one plant is consistently taller than the lawn two days after mowing, that is your candidate.

Nutlets on the Roots

Dig a plant up carefully and you find small hard tubers on the roots. That is the part surviving everything you have been spraying.

Wet or Compacted Ground

Heavy patches often sit where water stands or the soil is packed hard. Fixing that is part of fixing the weed.

What Fixes It

Fertilization & Weed Control

Nutsedge needs a sedge-specific herbicide and repeat timing to exhaust the nutlets. That is part of the spray program.

Core Aeration

Nutsedge favors compacted, poorly drained soil. Relieving that removes the conditions it prefers.

Turf Growth Control

A thicker, denser bermuda stand crowds sedge out and leaves it less bare ground to exploit.
