Nut sedge in lawn

Nutsedge is a grassy weed that is very noticeable this time of year. Often an indication of an area having poor drainage or over watered, as in the case of a leak sprinker system.

Nutsedge, or nut grass, is best controlled when caught early in it’s life cycle. Like many weeds, as nutsedge matures it becomes more tolerant to products targeted at eradicating it.

Once an area is infested, the momentum is in the sedge’s favor. Sedge can even tolerate doughts. Control of sedge can be achieve a number of ways. When possible, Winkler’s Lawn Care & Landscape, recommends pulling the nutsedge in such a way that the root system is removed. Cutting the leaf blades regularly also changes the function of the nut grass from producing tuber(leading to additional nut grass shoots) to regenerating leaf growth. Therefore, the spread is limited, but the nutgrass will remain.

Nut sedge close upIf controlling nut grass is at a point that you have a zero tolerance of it, it may be time to consider treating the area with a selective herbicide. Selective herbicides are designed to control only the desired target. In the case of nutsedge, a selective herbicide designed to control nutsedge would be the best product for the job.

Scientists have created a number of products that are capable of the job. Sedgehammer is a very common product used to control nutsedge. Sedgehammer’s active ingredient is halosulfuron. 1-2 applications of halosulfuron will yellow the leaf blade and ultimately lead to the death of the weed. Later season applications may only eradicate the portion of weed above the ground and not be drawn into the root zone leaving the weed alive to grow another season.

So, treat your lawn early when you see grass weeds. If you’re unable to manage an outbreak yourself, contact the Turf Specialists at Winkler’s to start your Turf Management Program today.
