Dealing with Yellow Nutsedge

It can be very difficult to control. Nutsedges are perennial weeds in the sedge family that superficially resemble grasses. Although they're often referred to as nutgrass, and do indeed resemble grasses, they're not grasses at all, rather they're true sedges.

Nutsedges grow mainly from tubers – or nutlets – formed on rhizomes, mostly in the upper 12 inches of the soil. Their leaves (or bracts) are V-shaped in cross section, thicker and stiffer than most grasses, and are arranged in sets of three at the base, whereas grass leaves are in sets of two. Their stems are solid, and in cross section are triangular in shape, while grass stems are hollow and round, and in cross section are almost flat or oval.

Yellow Nutsedge is the variety most common to Northern Virginia, and you'll want to know as much as you can about it to ensure your lawn care efforts are well targeted. During the Summer this grass-like weed will grow much faster than your grass, so will soon grow above it… and quickly become quite apparent. It’s yellowy/green in color, and if allowed to grow too tall, will form yellowy-brown spiked seed heads. If left untreated, the leaves will die back in the Fall, only to sprout again late the following Spring. Nutsedges prefer poorly drained soil and spread both by seed and underground tubers, which are about the size of popcorn kernels. You can easily pull the stem and leaves out of the ground, but you’ll almost always leave the tubers behind… and they're sure to sprout new leaves. Nutsedge is one of the most difficult weeds to control selectively, without damaging the good grass. In fact, many lawn care companies will tell you there's no chemical treatment for it. And if they do know of one, they still won’t offer it – because they lack the knowledge required to apply it safely and effectively… and the solution isn't cheap.

But at Bio Green we do have the required expertise, and we’ve had particularly good results using an application called Manage™ (halosulfuron). Unless it’s included in one of our complete lawn care programs, we offer nutsedge control treatment at an additional charge. Contact us for details and a no-obligation quote for your lawn.

If your lawn technician notices nutsedge in your lawn he/she should alert you and note it in your file. If you decide you’d like to schedule nutsedge control treatment, call our office at 730.450.0034. Mowing your lawn often enough to prevent the seed heads from forming will help to minimize the risk it spreading. And if you know there's nutsedge in your neighbor's lawn, make sure you get them to agree to cutting their lawn frequently tool, and share this article with them

What Our Clients Say

  • Joe, Broadlands, VA
    My satisfaction with Bio Green is based largely on the broad range of outdoor services they can provide, as well as the professional talent of their staff. They can support every aspect of exterior yard and facilities development and maintenance. I began many years ago with lawn care, but as my needs grew, I increasingly turned to Bio Green for support. Soon after starting lawn care, I needed maintenance and support for a lawn sprinkler system, then water drainage issues caused me to consult them for installation of several underground water diversion projects. In each of these areas, Bio Green proved not only able to offer their services, but I found the personnel who performed the various tasks to be very knowledgeable and expert in attacking the problem. I now have a comprehensive services contract with Bio Green that provides me with the confidence that any necessary yard care task will be professionally provided promptly and at a fair price.
