What Are Alternative Methods to Kill Nutgrass

Digging Out

Digging out nutgrass from roots is a good way to get the required results. This is highly effective because you can dig out nutgrass at different growth levels.

Removing it in the early stages of growth is best because the roots will hardly reach the depth of 50 cm, which you can dig using a trowel or spade.

Applying Pre-Emergent Weed Killers

What could be better than inhibiting the growth of nutgrass altogether? All you need to do is to mow the ground and apply pre-emergent weed killers. This will prevent the nutgrass from popping out of the ground but ensure safe chemicals for your soil and other plants.

Another easy trick is to add shade to your lawn where nutgrass is grown. This weed grows rapidly under the sun, but shade will limit its infestation. However, do not exceed the shade from limited areas to surround other valuable plants that need sunlight.

Mulching

Instead of relying on chemicals, you can get rid of nutgrass by using some weeding tools. One of the best ways is to use mulch by chopping tree bark, leaves, straw, and grass. All these forms of mulch can do the job conveniently.

It is recommended to keep the layer 3 inches thick; within this thickness, the seeds of nutgrass will not sprout. However, keep the mulch a little distant from the valuable plants. The mulch will add several benefits to your soil by keeping it moist instead of drying and keeping the temperature optimum in summer.

Using Sugar

Will sugar kill nutgrass? It seems interesting to rely on sugar instead of vinegar which has harmful impacts on other plants. But the nutgrass will die at the surface, and roots will remain firm.

However, there is an amazing benefit of this method, it is completely safe for soil and doesn’t harm other plants. Also, the sugar will add more nutrients to the soil and acts as a fertilizer.

How Long Does Vinegar Take to Kill Nutgrass?

Usually, vinegar requires almost 24 to 72 hours to kill nutgrass. If the infestation is controllable and nutgrass isn’t deeply rooted, vinegar will take less time to deliver an outcome.

However, you will need to keep spraying it for the coming days, as you may not get the best results with just a single treatment. Slowly but steadily, treatment will dry out all the nutgrass foliage.
