How To Get Rid Of Nutsedge

Nutsedge has become one of the most problematic weeds in home lawns and landscape beds throughout New Jersey, but there are ways to help you get rid of nutsedge on your property.

What is Nutsedge?

Nutsedge, or sometimes called Nutgrass, is a perennial weed from the sedge family. A sedge is a plant that looks like grass but is not a grass at all. A nutsedge plant spreads underground through rhizomes and tubers. Nutsedge survives from one season to the next by producing nutlets, which are small underground bulb-like seeds.The roots and rhizomes can produce several hundred of these nutlets during the active growing months. A nutsedge plant also produces seeds above the soil surface, which can aid in spreading nutsedge even further. Once the region gets its first frost of the season, it dies off on its own however, the nutlets under the soil survives over the winter and regrow the next year. They have the ability to live under the soil for multiple years at a time. Getting rid of nutgrass or nutsedge may be difficult, but there are ways to help control the weed.

What does Nutsedge look like?

Nutsedge mostly grows in areas of high moisture, which normally include low lying areas of the lawn, poor drainage areas or next to a broken/leaky sprinkler head. Once it is established, it can tolerate normal levels of moisture and thrive throughout the hot dry summer months.

2. Pour the mixture over into a garden sprayer for uniform spraying, and then spread evenly over the Nutgrass plants.

If youve given the other natural weed killers a shot and are still dealing with nutgrass poking up out of the ground, it might be time to move on from chemical solutions and try brute force.

Ways To Remove Or Help Control Nutsedge Plants

This method is effective when the soil is moist or soft enough to let you pull out the entire root of the weed, including its nutlets and rhizomes. If the roots remain in the ground, it will grow again, and youre back to square one. It will also be helpful if you plant grasses that can act as weed control against the growth of this pest.

If youre looking for other organic ways to get rid of them, you wont be able to find any. But there are other methods that are proven to be effective in controlling nutsedge weeds. Combining these methods is said to be the most effective in nutsedge removal as suggested by the HGIC.

Control In The Vegetable Garden

Killing nutsedge in the lawn with sedgehammer

Cultural Control: Nutsedges thrive in moist areas, and their presence often indicates that drainage is poor, irrigation is too frequent, or sprinklers are leaky. However, once established, they will tolerate normal moisture levels or even drought.

Nutsedge tubers are spread by cultivation and introduced in topsoil, where they can persist for years. Learn to recognize nutsedge to avoid accidentally bringing it in on newly purchased topsoil. Be sure to thoroughly clean tools and equipment such as tillers that have been used in an infested area to avoid spreading tubers and rhizome pieces.

Since nutsedges do not grow well in the shade, areas of the vegetable garden can be rotated into a solidly planted, dense, relatively tall crop such as beans or southern peas for a season. This will reduce the amount of nutsedge in the garden over several seasons.

Using a tiller to destroy mature plants will only spread the infestation as it moves the tubers around in the soil. However, repeated, frequent tilling of small areas before the plants have six leaves can gradually reduce populations. Tilling for nutsedge suppression should be limited to times when the soil is dry. Tilling when soil is wet is more likely to move tubers into new areas as they adhere to equipment.

Treat Your Garden With Liquid Horticultural Molasses

SFGATE also suggests using this treatment on weeds appearing outside the mulched area. All you to do is create a mixture of water and liquid horticultural molasses. Combine 1/4 to half a cup of molasses and a gallon of water, you can use a backpack sprayer to help make this task easier. Gardening experts say that two or three applications of the mixture will kill the nutsedge weeds in your vegetable garden.

Feeding With Enough Fertilizer

Feeding your lawn with less fertilizerleads to tough competition with the weeds while too much nurtures weed. Its always good to strike a balance during application by following the package rates. Fertilizer with a higher nitrogen percentage usually provides a steady slow supply of nutrients. Apply your fertilizer on time as this will result to a healthy grass lawn.

Avoid Flooding Your Garden With Water

Watering plants is a common practice. But if you notice nutsedge weeds growing in your vegetable garden, reduce the amount of water you give to your plants. Irrigate when the vegetable you cultivate need irrigation. The nutgrass weed thrives on moist and wet soil, so make sure that you dont over water your plants.

Other Ways To Control Nutgrass

How to Get Rid of Nutgrass or Nutsedge

You can dig up small nutgrass patches successfully. In the early spring, dig in at least 10 inches at minimum and then 8 to 10 inches out around the diameter of the nutgrass clump. Do this in the summer and fall, and, as a reminder, clean off your digging equipment when finished.

Using regular black polyethylene plastic mulch doesn’t prevent nutsedge, but polypropylene landscape fabrics can suppress the weeds from growing. These fabrics are also air and water permeable. After removing any existing nutgrass, put down this layer as a protective measure before you plant your new lawn or garden. Then cover the nonwoven landscape fabric with gravel or bark mulch.

Since nutgrass dislikes shaded areas, you can relocate your garden beds to areas that receive less sun. Then, replant them with shrubs or ground cover. Another possible solution: Stop watering the lawn in the areas in which the nutgrass is thriving. Allow it to dry, and till the soil frequently to help it air out. If this works, the sun will dry out the tubers, and the nutgrass will die. However, following this procedure can be difficult to do in areas where the grass and other plants need water.
