Nutsedge is a grass-like perennial lawn weed that grows faster in hot weather than our lawns. It prefers moist soil but will grow in dry soil as well. The V-shaped stem distinguishes it from grasses. In late spring to mid-summer, nutsedge produces tubers called "nutlets" and underground rhizomes that sprout new plantlets. Individual nutsedge Killer plants can grow to form patches 10 feet or larger in diameter.
Nut sedges are invasive weeds that commonly infest lawns, vegetable and flower gardens, and residential landscapes. They can be extremely difficult to eradicate, and control is likely to take a long time. Ortho nutsedge killer control requires both cultural and chemical management methods to be effective.
After an ortho nutsedge killer for lawns infestation has been controlled, sanitation is essential to prevent new introductions. To prevent the spread of these aggressive and difficult-to-control weeds, any new infestations should be managed as soon as possible.
Prevention And Maintenance
Mow At A High Height To Help Control Nutsedge.
Changing the way you mow can help control nutsedge or nutgrass depending on your turf type and latitude. Mowing your lawn at the proper height, which is usually one of the mower's two highest settings, allows the grass to crowd out nutsedge and other weeds. Cutting the grass short encourages nutsedge.
Get Rid Of Nutsedge On Your Lawn
Apply Ortho Nutsedge Killer Ready-To-Spray to your lawn to control nutsedge. It is effective against both new and established sedges. The weed turns yellow in 1-2 days and dies completely in 2- 3 weeks. It is rainproof in 2 hours and can be used on both Northern and Southern turf grasses.
Remove Nutsedge From Your Lawn
To kill nutsedge quickly and permanently in landscape beds and hardscapes, use Ortho GroundClear Super Weed & Grass Killer. The formula is intended to eliminate nutsedge as well as 174 other types of weeds, roots, and all.
Control in the Lawn
Cultural Control: Nutsedges thrive in moist environments, and their presence often indicates that drainage is poor, irrigation is excessive, or sprinklers are leaking. They will, however, tolerate normal moisture levels or even drought once established.
Nutsedge tubers are introduced into topsoil and nursery stock through cultivation. They can live for years in the soil. Learn to identify nutsedge to avoid introducing it into newly purchased sod, topsoil, or plants. To avoid spreading tubers and rhizome pieces, thoroughly clean tools and equipment such as tillers that have been used in an infested area.
Mechanical Control: Digging can be used to remove very small patches of nutsedge. Dig at least 10 inches deep and eight to ten inches beyond the diameter of the plant's aboveground leafy portion. This will ensure that the spreading tubers are removed. This is best done early in the spring before the tubers begin to grow.
Chemical Control: Postemergence herbicides can be used to control nutsedges. Because different herbicides are effective against different species, it is critical to identify the nutsedge that needs to be controlled. Herbicides also differ in terms of which desirable plants they can be used on without causing harm. Always read the label to ensure that the pesticide you choose will not harm the plants you want to grow.
Herbicides should be applied when nutsedge is actively growing in warm, moist soil. Water the lawn the day before spraying to help protect it and ensure that the weeds are actively growing.
1 Should you remove Nutsedge?
Pulling Nutsedge is a bad idea. Pulling nutsedge sends a signal to underground tubers to spread and produce new growth. While persistent pulling can weaken the plant over time, it is more likely to cause harm than good.
2 Will Pre-emergents protect against Nutsedge?
Pre-emergents will technically prevent Nutsedge from growing from seed, but because Nutsedge is a perennial weed that spreads through underground tubers and rhizomes, it will not prevent Nutsedge from returning every year if it is already present in your lawn.
3 Is it possible to kill Nutsedge organically?
There is no perfect way to organically control Nutsedge. You can try pulling weeds as you see them, but you must be extremely persistent because hand-pulling can actually cause the weed to grow more before dying back. Maintaining a healthy, well-fed lawn and addressing issues such as soil compaction and drainage where nutsedge is likely to thrive are your best bets for organic control of nutsedge.
