How To Get Rid Of Nutsedge Grass

Have you ever encountered a weed that just won’t go away no matter how much you try? Nutsedge, also known as nutgrass, is that very weed. This stubborn plant is the bane of lawn enthusiasts and gardeners alike. Here’s everything you need to know about nutsedge, why it’s such a hassle, and how to get rid of it for good.

What is Nutsedge?

Nutsedge grass in a lawn

Nutsedge is a type of weed that belongs to the same family as grass. It is characterized by its triangular stem, yellow-green leaves, and small, brown seed heads that bloom in the summer. It thrives in warm, humid climates and can be found in lawns, gardens, and even along roadsides and ditches.

The Types of Nutsedge

  • Yellow Nutsedge – the most common type of nutsedge that grows in most parts of the world.
  • Purple Nutsedge – a more aggressive type of nutsedge that grows in wet areas and can easily overtake lawns.
  • Hybrid Nutsedge – a combination of both yellow and purple nutsedge that can be difficult to identify and control.

Why is Nutsedge Such a Problem?

Nutsedge growth on a lawn

Nutsedge may look harmless, but it can cause serious damage to your lawn and garden. Here are a few reasons why:

Rapid Growth

Nutsedge is an incredibly fast-growing weed. It can grow up to three times faster than your lawn grass, reaching heights of up to three feet if left unchecked.


Nutsedge spreads quickly and aggressively through seed production and underground tubers, which can grow up to 8 inches deep. This means that even if you remove the visible parts of the weed, there’s a good chance that it will come back stronger than ever.

Drought Tolerance

Nutsedge is incredibly tolerant of drought conditions, making it difficult to control in arid areas.

Difficult to Control

Nutsedge can be incredibly difficult to control, especially if it has already spread throughout your lawn or garden. It’s resistant to most herbicides, and even those that do work may require multiple applications to fully eradicate the weed.

How to Get Rid of Nutsedge

Nutsedge removal with a garden tool

While nutsedge may be difficult to control, it’s not impossible. Here are a few methods you can try to get rid of nutsedge for good:

Hand Removal

One of the best ways to control nutsedge is to remove it by hand. This works best if you catch the weed early on before it has a chance to spread. Use a garden tool to dig up the entire plant, including the tubers, and dispose of it in a trash bag.


Mulching can help control nutsedge by blocking out sunlight and preventing the weed from growing. Apply a layer of mulch around your garden or lawn, making sure to cover any areas where nutsedge is known to grow.


If hand removal and mulching aren’t doing the trick, you may want to consider using an herbicide. There are a few herbicides on the market that are specifically designed to control nutsedge, such as Sedgehammer and Image Herbicide. Make sure to follow the instructions carefully, as these herbicides can be harmful to other plants if not used correctly.

Preventing Nutsedge

Nutsedge prevention by proper lawn care

The best way to deal with nutsedge is to prevent it from growing in the first place. Here are a few tips to help you do just that:

Proper Lawn Care

A healthy, well-maintained lawn is less susceptible to weeds like nutsedge. Make sure to fertilize and water your lawn regularly, and mow it at the proper height. Thick, healthy grass will make it hard for nutsedge to take root.

Identify and Remove Nutsedge Early On

The earlier you can catch nutsedge, the easier it will be to control. Keep an eye out for the weed in your lawn and garden, and remove it as soon as you spot it.

Practice Good Soil Management

Nutsedge thrives in wet, poorly-drained soil. Make sure your soil is well-drained and aerated to discourage nutsedge from growing.
