Use Liquid Horticultural Molasses
Spot-treat any nutsedge weeds that appear outside of your mulched area by drenching them with a mixture of liquid horticultural molasses and water, created by combining 1/4 to 1/2 cup of molasses with a gallon of water. Following at least two or three applications, the nutsedge will die, reports organic gardening expert and Texas Organic Research Center chairman Howard Garrett.

Control Nutgrass With Dish Soap
Dish soap isnt just a good solution to clean greasy dishes but can be used to kill bugs, and alongside vinegar and salt to kill Nutgrass. Dish soap basically serves as a binding agent and allows the salt and vinegar to stick to the Nutgrass leaves.
When this happens, the acetic acid and the salt dries out the Nutgrass leaves, which hinders its ability to make food, eventually killing it.
1. Start by adding one cup of salt and one tablespoon of dish soap to one gallon of vinegar, and mix thoroughly.
2. You will need to pour this mixture through a funnel into a spray bottle, without spilling it all over the place.
3. Even though you can use any vinegar to kill Nutgrass, it is best to choose one with at least 10 percent to 20 percent level of acetic acid, and use dish soap that is not antibacterial. Given that vinegar can sting, you should throw on a pair of safety gloves and glasses when working with this mixture.
4. Spray the Nutgrass with dish soap on a hot, preferably dry day, and repeat application if necessary within a couple weeks or so.

Where Does Nutsedge Typically Grow
Sedges like nutsedge typically grow and spread most voraciously in moist, compacted, poor-quality dirt.
Because of this, nutsedge will often take over yards that have drainage issues and/or overly compacted soil. Excessive watering or rainfall will also exacerbate these ideal conditions for nutsedge to grow in your lawn. With that said, nutsedge will still be able to grow in dry areas with sufficient drainage, provided there is little competition from other grass or plants.
How To Spot And Identify Nutsedge In Your Lawn
As mentioned above, Nutsedge looks very similar to most species of tall grass. As a result, it may be harder to spot at first, but as the season goes on, it will be almost impossible to miss and painful to look at.
For starters, Nutsedge is usually a very light green, almost yellow in color. This can disrupt the desired color of your lawn and give the appearance of an unhealthy lawn. If nothing else, it will stand out like a sore thumb among your dark green turfgrass.
Another thing that is hard to miss is its height. Nutsedge grows a lot taller than most species of lawn grasses which makes for even more inconsistencies in the appearance of your lawn.
Between the difference in color, growth rate , it will always stand out in your lawn.
If your nutsedge has had time to grow and spread, you will also notice flowers blooming in the center of clustered leaves of three.
The flowers may even have different colors depending on the season. Once Nutsedge has had time to grow into its full form, its hard to miss.

How To Tell The Difference Between Sedge Weeds And Grass
These sedge weeds are tricky! Sedge is often mistaken for grassy weeds since they can be difficult to distinguish from turfgrass at first glance. However, upon closer inspection, youll find that sedges have triangular stems and three rows of leaves. Their leaves also grow at a much faster rate than lawn grasses during the hot summer weather, making them more noticeable in your yard. If you see these weeds popping up, it might be time to call your TruGreen specialist.
Final Thoughts On Removing Nutsedge From Your Lawn
Regardless of the species, weeds taking over your lawn can be a nightmare. They waste your time and ruin the appearance of an otherwise healthy lawn.

Ive Never Had It Before
Nutgrass is a persistent weed. It has been shown that nuts can remain dormant or inactive in the soil for up to 10 years. There have even been reports of nuts up to 30cm below the surface in heavy clay soils shooting only after being disturbed by vehicle movement. The weight of a vehicle shifts and cracks the earth allowing water and oxygen deeper into the soil.
Nutgrass growth is severely restricted by shade. Most other weeds and many larger crop or landscape plants can eventually dominate nutgrass, but rarely will they completely suppress it. Nutgrass will almost always persist if not adequately controlled due to its complicated interconnected network of underground rhizomes . Nutgrass grows most rapidly in full sunlight when adequate nutrients are available. It becomes more serious when allowed to grow without competition from other plants and this can occur when annual weeds are removed manually or by herbicide, crops are harvested or the topsoil is cultivated or disturbed for new plantings.
As stated above, nutgrass only competes well in perfect growing conditions. It is for this reason that infestations are often noticed for the first time when we spend a little time in our gardens. Fluffing up, cultivating or improving the soil, importing new rich fertile soil, fertilising, weeding, removing old plants and heavy watering are all activities that can disturb nuts and encourage them to shoot.
