Nut Grass Prevention
Nutgrass, also called nutsedge, refers to a perennial grass-like weed that has shiny, upright yellow-green or brownish-purple leaves. Nutgrass quickly spreads its roots underground, making it difficult to eliminate. However, you can prevent nutgrass with proper care of your lawn and ornamental beds. Does this Spark an idea?

Lawn Care
-
Prevent nutgrass in your lawn by watering as infrequently as possible and improving drainage, if necessary. In addition, improve your lawn-care practices in order to keep your grass as dense and strong as possible. Dense grass prevents sunlight from reaching nutgrass seeds in the soil. Keep your grass dense by keeping your mower blades sharp, avoiding cutting your grass too low and fertilizing properly.
Ornamental Beds
-
Prevent nutgrass in ornamental beds by ensuring the beds drain properly. Do not water your beds unless your plants visibly need it. Overwatering and wet soil often cause nutgrass. Apply mulch on your ornamental beds after planting to prevent sunlight from reaching nutgrass seeds.

Treatment
-
Hand-pulling nutgrass can remove early infestations. Make sure you remove the entire root system. Reduce watering, if possible. If a large infestation occurs, you may need to use an herbicide. Many herbicides are ineffective on nutgrass, but Basagran (bentazon) and Manage (halosulfuron) kill nutgrass.
