We have put together two different safety kits that will make selecting the correct safety gear easier for you. Nutsedge, also known as nut grass, is a weed commonly found in lawns during the summer. These weeds stand taller than the grass in your lawn and are notoriously hard to get rid of given their immersive root systems. Nutsedge is a perennial sedge, meaning it is a grasslike plant that will live for at least two years and will come back year after year. Use this guide to identify nutsedge in your lawn.
Then, read the rest of our 4-part guide to learn how to get rid of nutsedge and where nutsedge grows. Nutsedge is easily identifiable from grass because it is taller than grass.
Nutsedge grows much quicker than grass, even after being mowed. Nutsedge weeds, like all sedges grasslike plantshave a triangular stem that can be felt in your hands. The stem of the sedge feels like it has 3 sides or 3 points, much like a triangle. Nutsedge looks like long grass blades.
At the end of a nutsedge stem, you will commonly find 3 leaves and flowers. The flowers can be different colors but are most commonly yellow or purple dark red. Yellow nutsedge, or nutsedge with yellow flowers, often grows in the middle of the summer while purple nutsedge nutsedge with deep red or purple flowers grows in the late summer. Nutsedge is typically identified by its root system. Nutsedge has roots, called rhizomes, that can reach inches below ground.
Rhizomes will grow horizontally under the soil and emerge out of the soil to form a new sedge plant. This means multiple sedges may be connected by one series of rhizomes. The roots will also have small, starchy tuber structures known as "nutlets" attached. If you see nutlets in the roots of the plant, you know for certain you have nutsedge.
Nutsedge weeds grow during the spring and summer and are perennial, meaning they come back year after year. In this video, we'll show you what nutsedge looks like and how you can identify it in your lawn.

Check this madness out right here.Nutsedges are very aggressive and persistent weeds that commonly infest lawns, vegetable and flower gardens, and home landscapes. They can be very difficult to eradicate and their control is likely to be a long process.
Successful control involves both cultural and chemical management methods. Once a nutsedge infestation has been controlled, sanitation to prevent new introductions is critical. Any new infestations should be managed right away to prevent spread of these aggressive and difficult-to-control weeds. Yellow nutsedge Cyperus esculentus. Correct identification is very important, as most herbicides for grass control are not effective on sedges. Nutsedges can be distinguished from grasses by their stems, which are triangular or V-shaped in cross section, while grass stems are hollow and round.
Their leaves are thicker and stiffer than most grasses and are arranged in groups of three at the base. Nutsedge leaves appear creased with prominent mid-veins. Most nutsedges are perennials whose leaves die back in the fall when temperatures decrease. The tubers and rhizomes can grow eight to 14 inches below the soil surface. Nutsedges thrive in almost any kind of soil.
While they prefer moist soil, established nutsedge plants will thrive even in dry soil. They spread by small tubers, by creeping rhizomes or by seed. New tubers begin forming four to six weeks after a new shoot emerges. Individual nutsedge plants may eventually form patches 10 feet or more in diameter.
Purple nutsedge Cyperus rotundus. Purple nutsedge Cyperus rotundus and yellow nutsedge Cyperus esculentus are the most common nutsedges in South Carolina.
Yellow nutsedge is more widespread than purple nutsedge due to its greater cold tolerance. However, where purple nutsedge is adapted, it can be even more vigorous than yellow nutsedge. The two species often grow together. Because purple and yellow nutsedges differ in herbicide susceptibility, correct identification is critical to successful control.Yellow and purple nutsedge are tenacious, aggressive weeds that spell trouble for lawn owners.
Also known as nutgrass, nutsedges often escape control because they're not like weed grasses or broadleaf weeds targeted by most weed killers.
These perennial weeds are sedges that come back year after year and reproduce in ways that complicate their control. By understanding these nutsedge basics and treating effectively, you can kill and control these difficult lawn weeds:. Nutlets formed below ground stay viable for many years. Effective treatment and control of yellow and purple nutsedges calls for products designed to overcome the unique challenges of these difficult weeds.

Augustinegrass, Zoysiagrass and Buffalograss. This convenient, ready-to-spray product provides visible results in three to seven days and kills yellow nutsedge within two to three weeks. Purple nutsedge may need repeat treatment every three to four weeks for effective control.
Treat nutsedge in summer lawns after turf greens up in spring and before winter dormancy sets in. Only treat while nutsedge and lawn grasses are both actively growing. Maximize your results by treating during late spring and early summer, when nutlets and seeds sprout and still have less than five to six leaves.
This timing hits these young weeds at their most vulnerable and kills them before new nutlets start forming in mid to late summer. By practicing good lawn care basics, you can protect against nutsedge invasions and give your grass an advantage over these aggressive weed pests. Healthy, vigorous grass is an excellent defense against yellow and purple nutsedge in lawns. Take steps to correct low-lying, poorly drained areas and avoid overwatering.
Instead of frequent shallow irrigation, irrigate deeply and infrequently. This supports deep, healthy grass roots and enhances resilience. Mow your lawn at the recommended height for your grass type. Mowing too short can stress turf grasses and encourage nutsedge growth. Yellow and purple nutsedge are tenacious lawn weeds, but you can take them on with confidence. Schonbeck, M. Patton, A. Identifying Nutsedge in Your Lawn. Nutsedge makes itself known during periods of rapid summer growth as it outcompetes heat-challenged lawn grasses for water and nutrients.
The bright yellow-green leaves of yellow nutsedge stand out clearly against turf, as do the dark green leaves of its purple relative.
Left to grow tall, nutsedges produce distinctive spiky flower clusters: yellow-brown for yellow nutsedge and purple-brown for purple nutsedge. The key identifying feature for these difficult weeds is their triangular stems. Roll the stems between your fingers, and you'll understand the meaning of the old-time rhyme "sedges have edges. Shiny, smooth nutsedge leaves have a distinct center rib and form a "V" shape. Nutsedge outbreaks often start in moist, poorly drained lawn areas, where they quickly develop into large colonies.
Their extensive root systems may reach up to 4 feet deep. Yellow nutsedge leaves stand out easily in lawns. Understanding How Nutsedge Spreads. Nutsedges spread and reproduce in several ways. Plants may flower and release seeds that germinate and sprout into new plants. These weeds also spread via underground stems, known as rhizomes, which send up shoots that become new plants.Click on images to enlarge. Nutsedges are perennial weeds in the sedge family and superficially resemble grasses.
They are among the most problematic weeds of agriculture in temperate to tropical zones worldwide. They are difficult to control, often form dense colonies, and can greatly reduce crop yields. In California, nutsedges are particularly problematic in summer-irrigated annual and perennial crops.
Yellow nutsedge, Cyperus esculentus, grows throughout California to an altitude of roughly feet m. Purple nutsedge, Cyperus rotundus, is not as widespread in California, but does grow in the Central Valley, South Coast, and low desert, to about feet m. Seedlings are rarely found. Seedling leaves look similar to that of mature plants, but are smaller and finer.
The stem base is slightly triangular and the midvein area is usually pale. The first two to three leaves emerge together, folded lengthwise. Nutsedges grow mainly from tubers formed on underground, horizontal creeping stems called rhizomes, mostly in the upper foot of soil. Sprouts from tubers are similar in appearance to the mature plant.
Sedge stems are erect and hairless. Although sedge leaves superficially resemble grass leaves, they lack collars, ligules, and auricles. Sedge leaves are thicker and stiffer than most grasses, are V-shaped in cross-section, and arranged in sets of three from the base rather than sets of two as found in grass leaves.
Sedge stems are triangular in cross-section; grass stems are hollow and round. Yellow nutsedge stems grow to 3 feet 0. Tubers of yellow nutsedge are produced singly while purple nutsedge tubers are produced in chains, with several on a single rhizome.
Purple nutsedge spikelets are dark reddish to purplish brown. Yellow nustsedge spikelets are straw-colored to gold-brown with many flowers. Yellow nutsedge has tiny, single-seeded fruit achenes that are football shaped, triangular in cross-section, and brown. Purple nutsedge does not typically produce seeds in the United States. Both nutsedge species reproduce by underground tubers that are attached to underground stems.
Yellow nutsedge also produce seed in California, but they have low viability and are not considered a more source of reproduction and spread.Last Updated: August 24, References Approved.

It has strong roots and nodules that are often referred to as "nuts" hence the name. The most thorough way to rid your lawn of nut grass is by removing the plant, root and all, by hand. You can also try chemical herbicides, however, or you can coat the grass in sugar as an organic alternative.
To get rid of nutgrass, slip on a pair of gardening gloves and use a small shovel to carefully dig down to the roots of the plant. The roots can be up to 12 to 18 inches deep, so keep digging until you find the ends of the root system. Once you reach the bottom of the roots, carefully dig out the plant to avoid leaving any roots behind. Then, dispose of the plant right away so it won't have a chance to spread. To help prevent nutgrass, each spring you should water your lawn and then sift sugar onto the grass.
