Although yellow nutsedge, also known as a tiger nut, has a waxy and bright green look, you should not classify it as grass.
It is a sedge with a triangular stem in a cross-section. You can find this variety outgrow surrounding the grass.
Then, as a perennial plant, it is reproduced by the underground tubers and seed.
It grows in high moisture areas with poor drainage. However, you can also find this sedge in low spots and drier sites.
That is why it is too problematic to control.
Despite its knotty behavior for lawns and rice fields, the tubers of this nutsedge have various benefits.
In some countries, people even cultivate these for drink and food.
Yellow Nutsedge Lifecycle
This nutsedge life cycle is so typical. It will grow in summer and continue to thrive in autumn.
Although the frost will stop the growth of this plant, the tubers under the soil will remain inactive and will be active for the next season.
When the first frost has fallen, it will only kill the yellow nutsedge on the upper part. The bottom or remaining part in the soil, specifically the tubers, will germinate afterward.
The tubers can persist inactive in the soil for several years. So, you need to be more careful about controlling this nutsedge.
How to Identify Yellow Nutsedge
Since the yellow nutsedges will grow in summer, it will be easier to reckon them during this season.
The leaves will grow faster that makes them stick out. You will notice if they are growing around.
There is also a chance to identify them even if it is not summer. You can identify them by looking at the color, stem, and leaves.
If there is a shiny light green to yellowish foliage with a triangular stem, it is indeed yellow nutsedge.
You can also look at the leaves closer. If it does not have tiny hairs on the leaf blades, it is surely this nutsedge.
Yellow Nutsedge Control and Management
Many professionals have stated that there is no outstanding organic control to shoot down the yellow nutsedges effectively.
However, there are still some ways to control them before calling professional help.
If there are only a few nutsedges on your lawn, you can pull them out carefully. To be more effective, do it when the sedges are starting to sprout in the spring.
That will be easier since the soil is moist in spring. As a result, you will be able to get the entire root and a little part of the tubers too.
In case you want to remove them more effectively, try to dig deep to the base to take the tubers out from the soil.
In this way, you have to make sure that there is no trace leaving.
To prevent the return of this nutsedge, you have to mow your turfgrass around 63 to 101 mm. The right height will promote better root growth.
At this condition, there is a low possibility for the yellow nutsedge to establish.
Utilizing vinegar on this tiger nut makes a great alternative as well. You can simply pour this acetic acid into a bottle and spray it directly to the nutsedge.
In contrast, it is always better to call a professional if there are a bunch of yellow nutsedges in your garden.
Do not even try to pull them out when they already thrived. It will make them grow more and more at this stage.

Timing is pretty crucial when treating yellow nutsedge with herbicide products.
The recommendation is to apply it at the end of spring to early summer. This way you will kill the plants before new tubers come out.
If you find this nutsedge in your planting beds, performing spot treatment with a chemical herbicide will provide good control as well.
Glyphosate, for example, can kill the nutsedge as well as its root.
