Green Kyllinga Control: How To Get Rid of Green Kyllinga

This page is a general DIY guide for controlling green kyllinga. Using the products and methods suggested you get control of green kyllinga. Follow this DIY article and use the recommended products, and we guarantee 100% control of green kyllinga.

Green Kyllinga is a weed that comes from the sedge family and has become a rising problem in the southeastern part of the United States. Believed to be native to Asia, Green Kyllinga was first discovered in the country about 50 years ago.

In the last 10 to 15 years, Kyllinga has developed into a major problem for turfgrass and landscape managers. The main issue with Green Kyllinga is that it grows in dense mats that can quickly take over a garden or lawn and be an eyesore.

Kyllinga produces little nutsedge seed heads which can make 5,000 seeds per year. These seeds grow all year round before going dormant in the wintertime. Pulling or digging them out disperses the seeds. This also disturbs the roots and encourages more root hairs to grow so the best way to control them is by using chemicals.

If you have encountered Kyllinga on your lawn, our simple DIY Green Kyllinga treatment guide will show you exactly step-by-step what you need to do to get rid of this grassy weed for good. By carefully following our directions and using our professional herbicide recommendations, you can eliminate Green Kyllinga quickly and affordably.

Identification

Before you can proceed with a treatment program, you need to identify and make sure that the weed you are dealing with is green kyllinga and not some other weed. Misidentification can lead to using the wrong herbicides for treatment, costing you time and money. Here are some traits and facts on green kyllinga that can help you with identification.

Green kyllinga outbreak on a lawn

  • Green kyllinga is a erect perennial sedge weed that has dark green narrow leaves that extend from triangular stems, usually in sets of three. They reach up to 15 inches in height when unmowed. In areas that see mowing, the plant adapts and grows more prostrate.
  • It produces triangular stems that grow narrow leaves, usually in sets of three.
  • When this plant flowers, it produces a dense, globular flowerhead with over 100 green-to-white flowers. The flowerhead is about 3/8 of an inch in diameter.
  • When green kyllinga matures, they make oval-shaped green seedheads which they appear pointed or spiked in texture. The seedhead usually has three short leaves below it. Leaves do not have hairs or auricles, but they will have ridge along the midvein. 
  • Produces rhizomes that appear dark red to purple, which helps this weed to grow in low dense mats. As a perennial, it does grow underground rhizomes that allow the plant to survive, but unlike other sedges, it does not grow underground tubers.

Inspection

Green kyllinga is a not a typical weed homeowners are used to seeing since it's a relatively new problem, but it can spread quickly, ruining gardens as well as lawns.

Where to Inspect

Green kyllinga tends to thrive in areas with wet soil, although it can manage to thrive in areas of partial shade once established. 

Common areas where this weed grows is lawns, golf course turf, and athletic fields. 

What To Look For

Look closely for weeds that look similar to nutsedge but with less erect and smaller leaves. 

Treatment

Before proceeding with treatment, you will need to wear the proper personal protective equipment (PPE). 

To eliminate green kyllinga on commercial or residential properties, use a selective, post-emergent herbicide that’s labeled not to injure your property’s turfgrass.

We recommend you check out Sedgehammer Nutsedge Killer. Sedgehammer is made with halosulfuron-methyl and controls sedges and other weeds in warm-season and cool-season turf.

Step 1: Mix and Apply Sedgehammer

Mix and apply

Determine how much Sedgehammer to use by measuring the square footage of the treatment area. To do this, measure the length and width of the treatment area in feet then multiply them together (length X width = square footage). For acreage, take the square footage and divide it by one acre (square footage / 43,560 sq. ft. = acres). 

For spot treatments in turf with Sedgehammer Nutsedge Killer, use 0.9 grams of product per 1-2 gallons of water per 1,000 sq. ft. Add 2 tsp (1/3 fl oz) of nonionic surfactant per gallon of water

Mix this product into a hand-pump sprayer, starting by filling the sprayer up halfways with the required amount of water. Next add the proper amount of Sedgehammer Nutsedge Killer, and then adding in the remaining half of water.

Close the sprayer lid and agitate until the product is well mixed. 

Spot-treat any green kyllinga you have found. Use a fan or cone spray pattern to ensure the weeds are fully coated, and spray the weeds to the point of wet but not runoff. Be sure to spray on calm days when temperatures are not too hot and when wind speeds are low to minimize drift.

A second treatment can be applied 6 to 10 weeks after the initial treatment. 

Avoid contact of this product to leaves of desirable plants since foliar injury, discoloration or death may result.

Prevention

Once green kyllinga has been eliminated from your property, you will need to implement some preventative measures which will ensure that this weed does not return.

Mow lawn to prevent weed reinfestation

  • To prevent unwanted plants like green kyllinga from growing on your lawn, we recommend you promote the health of your turf to reduce the conducive conditions that allow weeds and disease to take hold.
  • Mow your grass at proper intervals to maintain a thick growing density. A lawn dense with taller trimmed grass is better able to choke out weeds and other unwanted grasses and prevent them from establishing.
  • Reduce the shade cast on your lawn by trimming overgrown shrubbery and tree branches, rake away leaf litter and pick up any debris, and employ a proper watering schedule to provide the local grass with enough water to strengthen its roots, but not so much that will encourage weeds. Many grasses require 1 inch of water every week. Apply the water all at once in the morning so it has time to seep into the ground without evaporating in the sun.
