Why is nutgrass so persistent?

Some call it nutsedge, some say nutgrass but whatever you call it, it is a persistent weed. If you ask Google, “what is nutsedge good for” it will tell you that it’s good for ground cover or lawn replacement. That is maybe the most accurate and scary description you will find. 

Do you want your lawn replaced by nutgrass?

The most prolific way that nutgrass reproduces is through underground tubers which are also called “nutlets”. These extensive root systems can reach up to four feet deep. This is one of the conditions that make nutgrass so persistent.

Nutgrass outbreaks usually occur during and after really wet springs, especially in lawns with poor drainage. Later in the summer when drought conditions exist, the persistent nutgrass or nutsedge continues to thrive. 

By summer, the roots are so deep and established that they can survive almost anything. Nutgrass survives because it beats out your grass for water and nutrients. While underground, nutlets can survive for up to 10 years before emerging again. Buried at depths like that, they are protected from cold weather and common treatments for killing nutgrass.

“sedge” versus “grass”

If you are wondering how to identify nutsedge (also called nutgrass) remember this phrase, “sedges have edges”. Just pull up a piece that you think might be sedge, if it feels triangular instead of round and smooth, it is a sedge. The sedge has a center “crease” or fold that makes it have a “v” shape. Imagine if you took a piece of flat grass and ironed it like a pants leg. 

Is nutgrass or nutsedge a bad thing?

A study conducted by the Mississippi State Extension service measured the effects of nutsedge or nutgrass on a sweet potato crop. If just a little nutgrass has devastating effects on a crop, imagine what it does when it takes over your lawn!
