What is Nutsedge Or Nutgrass?

A perennial sedge weed called nutsedge likes to grow in the moist parts of the lawn. It's particularly problematic because of how persistent it is. It can grow quite quickly in warm environments, such as those we have here in Memphis, Tennessee.

Nutsedge spreads via rhizomes and/or "tubers" underground, which are sometimes referred to as "nutlets," hence its name.

This weed can be distinguished by its vivid green hue and the fact that it can grow up to five times more quickly than the healthy grass in your lawn. A good chance that it's nutsedge exists if your entire lawn is level and some bright green weeds that resemble grass protrude from it.

Homeowners occasionally mistake the weedy sedge kyllinga for nutsedge, according to our research. Kyllinga has finer-textured leaves and a propensity to form dense mats. Additionally, it grows more slowly than other sedges.

Its height is another feature that is challenging to ignore. The appearance of your lawn will be even more inconsistent because nutsedge grows much taller (and faster) than the majority of lawn grass species.

It will always stand out in your lawn due to the difference in color, growth rate, and height.

If your nutsedge has had time to develop and spread, you will also notice flowers blooming in the middle of a cluster of three leaves.

According to the season, the flowers may even have various colors. The full form of Nutsedge is difficult to miss once it has had time to develop.

How to Get Rid of Nutgrass
