Nutsedge is a perennial weed in the Cyperaceae family — a group of grass-like plants that love moist soil. The most common type found in lawns and gardens is yellow nutsedge (Cyperus esculentus).
Despite its grassy appearance, nutsedge is not a true grass. It features:
- Triangular stems
- Glossy, bright green leaves
- Underground tubers (nutlets) that make it tough to kill
Why Is Nutsedge a Problem?
- Grows Fast: Outpaces lawn grass during hot summer months
- Hard to Kill: Underground nutlets regenerate new plants after mowing or cutting
- Spreads Quickly: One plant can produce hundreds of offspring through rhizomes and tubers
- Ugly in Turf: It disrupts lawn uniformity with tall, coarse, bright green growth
How to Identify Nutsedge
Watch for:
- Bright, waxy leaves that grow upright
- Triangular stems (roll one between your fingers — you’ll feel the edges)
- Taller, faster growth than the rest of the lawn
- Tends to thrive in wet or poorly drained soil
How to Control Nutsedge
1. Cultural Control
- Fix Drainage Issues: Nutsedge thrives in soggy spots. Level out low areas and avoid overwatering.
- Encourage a Dense Lawn: A thick, healthy lawn helps suppress nutsedge over time by reducing available space and sunlight.
Important:
We do not recommend pulling nutsedge by hand.
Pulling leaves the underground nutlet behind, which quickly sprouts new growth — making the problem worse.
2. Chemical Control – Spray, Don’t Pull
For effective control, spray using a selective herbicide designed for nutsedge.
We recommend:
Fertilome Weed-Out Nutsedge Control
This powerful, easy-to-use herbicide targets yellow nutsedge without harming most established turfgrasses.
Available in:
- 16oz Concentrate – great for larger areas or custom mixing
- 32oz Ready-To-Use – pre-mixed for spot treatments
- 32oz Ready-To-Spray – connects directly to a garden hose for wide coverage
When to Apply:
- Spray when nutsedge is actively growing (typically late spring through summer)
- Do not mow 2 days before or after application
- Rainfast within hours — follow label directions for best results
3. Stay Consistent
Controlling nutsedge is a process. Because it regrows from underground nutlets, multiple applications may be necessary throughout the growing season. Monitor your lawn, and reapply as needed for long-term control.
