What is nutgrass?

Nutgrass is a common problem in summer lawns. Nutsedge, (A.K.A. nutgrass), a perennial, tends to thrive under close mowing and are prolific in poorly drained or wet areas. Nutgrass or yellow nutsedge has triangular stems with leaves that branch out in three different directions. Light green to yellow, nutsedge grows quickly in spring and summer, outgrowing grass in just a couple of days after mowing.

Can I pull nutgrass?

Avoid pulling the nutgrass plant by hand. Pulling nutgrass will stress the plant and stimulate even more nutlets to sprout. Nutgrass plants regenerate from small nutlets formed on their root system under the soil surface these nutlets go unharmed by traditional contact weed controls, making nutsedge challenging to control.

What is the best control for nutgrass?

A liquid spray application using Nutbuster combined with Stikit, a non-ionic surfactant, is the most effective control for nutgrass in home lawns and landscapes.

What is Nutbuster?

Nutbuster is a selective herbicide for post-emergence control of sedges in established lawns, ornamental turfgrass, and landscaped areas. 

Will Nutbuster hurt my good grass?

When applied as directed under the conditions as described on labeled instructions cool season grasses such as fescue, rye, bluegrass and warm season zoysia grass are tolerant to this product.

How to mix Nutbuster

In a pump up hand garden sprayer, dissolve one water soluble bag of product into one gallon of water. Add two teaspoons of Uncle’s Stikit, a non-ionic surfactant, to this mix. One gallon of mixed product will cover approximately 1,000 square feet. A second treatment may be required 6 to 10 weeks later.


What is Stikit?

Uncle’s Stikit is a non-ionic spreader sticker. Stikit helps hold the herbicide on to the waxy leaf of the nutgrass.  When Stikit is added, water can spread covering more leaf surface resulting in a better uptake of the herbicide. Avoid using soaps and shampoos as a surfactant. They contain fragrance and dyes that can leave a precipitate residue on foliage.

Uncle’s tips when using Nutbuster

For optimum results, do not mow turf 2 days before or after application. Give the plant plenty of time to absorb herbicide deep into the root system and nutlets.

Spray the nutgrass thoroughly and wet the entire leaf surface.

Timing is everything, and early control is best. Nutgrass plants allowed to mature will stress when treated, stimulating more nutlets to sprout. However; be persistent and continue to spray the new plants as they emerge and you will be victorious.
