Nutsedge Killer & Control Herbicides
Nutsedge is a type of sedge that closely resembles a grassy weed, which is why it is also called nut grass. Nutsedge can ruin the appearance of your lawn because of the differing color and growth rate the sedge verses your turf. Nutsedge is extremely difficult to control because of various growth structures, so you’ll need to know exactly how to identify, prevent and kill this annoying lawn intruder.
How to Identify Nutsedge
Nutsedge weeds are easily identifiable plants. The triangular-shaped, yellow-green colored leaves have a thick mid-vein that makes the leaves appear creased, and are arranged in groups of three at the base of the plant. The thick leaves have a v-shaped cross-section as opposed to grass, which has a hollow cross-section. The shallow, fibrous root system produces tubers, which give the plants the “nut” in their name. These tubers serve as underground food storage chambers, and can also germinate and produce new plants. The rhizomes, or underground stems, of these plants can also produce new plants.
Nutsedge thrives in most all kinds of soils, but the presence of sedges can often indicate poor drainage, leaky sprinklers, or frequent irrigation. These plants can find their way into your lawn by the way of infested potting soil, and once they become established, they are extremely hard to get rid of.
The tubers of this plant can remain dormant in the soil for many years, which is one of the reasons this plant can be so difficult to completely remove. These plants can emerge through rocks and mulch and other landscaping materials.
