Nutgrass Control

Nutsedge—sometimes called nutgrass or watergrass—appears as tall, thin, glossy blades growing faster than surrounding turf. Although it looks like grass, nutsedge is actually a sedge, and it behaves very differently from typical lawn weeds.

How to Identify Nutsedge

Nutsedge has tall, narrow, shiny leaves that often stand above the lawn. The fastest way to identify it is to roll the stem between your fingers.

• Nutsedge has a triangular stem with three distinct sides.
• Grasses have round or flattened stems.

Why Pulling Nutsedge Doesn’t Work

Nutsedge spreads through underground structures called nutlets. When a plant is pulled, these nutlets sprout, often creating a thicker infestation.

• Nutlets can remain dormant in the soil for up to three years.
• Parent plants are perennial and regrow each season.
• Plants should never be allowed to set seed.

Nutsedge Control in Lawns

In turfgrass, nutsedge can be controlled with selective herbicides labeled specifically for sedges.

Bonide Sedge Ender is effective when applied according to label directions. Multiple applications may be necessary for long-term control.

Nutsedge Control in Landscape Beds

In landscape beds, control options are more limited.

• Nutsedge can be spot sprayed with a non-selective herbicide such as Hi-Yield Killzall (glyphosate).
• Care must be taken to avoid spraying desirable plants.
• Using cardboard or another shield helps prevent overspray.

Digging nutsedge out with a shovel is sometimes necessary, but it must be repeated throughout the season to remove regrowth.

Patience Is Key

Because nutsedge spreads through long-lived underground nutlets, complete control takes time. Consistent treatment and preventing seed production are the keys to long-term success.

Please read and follow all label instructions when applying any herbicides.
