What Is Nutsedge?

Nutsedge is a persistent, fast-growing weed that often invades lawns in warm, humid climates like those in Murfreesboro, TN. At first glance, it may look like a type of grass, but it’s actually part of the sedge family and behaves very differently from the turfgrass you're trying to maintain.

One of the most distinctive features of nutsedge is its triangular stem, which you can feel if you roll it between your fingers. It also tends to grow faster and taller than your regular lawn grass, making it stand out just days after mowing. Unlike broadleaf weeds, nutsedge produces long, narrow leaves and forms dense, upright clumps.

This weed thrives in warm, wet conditions, especially in areas with poor drainage, compacted soil, or excessive irrigation. It’s particularly common in low-lying sections of a lawn or spots where water tends to collect.

There are two main species you might encounter in Tennessee: yellow nutsedge and purple nutsedge. Both are aggressive and spread through underground tubers (called nutlets), making them difficult to remove completely without a targeted approach.

Why Nutsedge Is Hard to Kill

Unlike many common lawn weeds, nutsedge doesn’t respond well to standard weed control products. It’s not a broadleaf weed or typical grassy weed—it’s a sedge, which means many over-the-counter or general-purpose herbicides have little to no effect. Selective herbicides that work on dandelions, crabgrass, or clover often leave nutsedge untouched.

Part of what makes nutsedge so persistent is its underground tubers, or “nutlets.” These small root-like structures allow the plant to survive below the surface even after the top growth is removed. Each nutlet can generate multiple new shoots, making it easy for nutsedge to reappear even after it seems to be gone.

Because of this regenerative root system, nutsedge often comes back year after year if it isn’t treated with the right products at the right time. Control isn’t about a one-time spray—it’s about timing applications when the weed is actively growing and using targeted products that reach below the soil.

At Second Nature, we understand the life cycle of nutsedge and apply industry-proven treatments that go beyond surface-level control. Our licensed technicians use specialized herbicides and science-based scheduling to disrupt the weed’s growth and help restore balance to your lawn.

Signs You Have Nutsedge in Your Murfreesboro Lawn

Nutsedge can blend in with turfgrass at first, but it doesn’t stay hidden for long. One of the most noticeable signs is its rapid vertical growth. It tends to shoot up faster than the surrounding grass just a few days after mowing, creating uneven patches in an otherwise well-maintained lawn.

Visually, nutsedge has shiny, yellow-green leaves that emerge in clusters and form a distinct V-shaped stem. If you roll the stem between your fingers, you’ll feel a triangle shape, unlike the round stems of true grasses. Here are telltale signs of nutsedge in your lawn: 

It Grows Faster Than Your Grass

One of the first signs of nutsedge is how quickly it grows after mowing. Within just a few days, it can shoot above the rest of your turf, creating tall, uneven patches—even in well-maintained lawns.

Look for Shiny, Yellow-Green Leaves and V-Shaped Stems

Nutsedge has a distinctive appearance. The leaves are glossy and bright green or yellow-green, and they grow in tight, upright clusters. Its stems are V-shaped and triangular—if you roll one between your fingers, you’ll feel the difference compared to normal grass.

It Thrives in Damp, Disturbed Areas

You’re most likely to find nutsedge in poorly drained areas, over-irrigated sections, or anywhere the soil has been recently disturbed, like after installing new sod or making landscape changes. It loves moisture and loose soil, making it common in problem areas across Murfreesboro lawns.

Peak Growth in Late Spring Through Summer

In Middle Tennessee, nutsedge typically appears in late spring and thrives throughout the hot, humid summer months. It takes advantage of warm weather and excess moisture, which is why timely identification is so important.

Second Nature’s team is trained to recognize these signs early and apply targeted treatments when the weed is most active, helping prevent long-term infestation and protect the health of your lawn.

What Weed Killers Work on Nutsedge

Nutsedge is one of those weeds that requires more than a general spray. While broadleaf weed control can manage many common lawn invaders, nutsedge needs a targeted approach. That’s because it’s not a typical broadleaf or grassy weed—it’s a sedge, and it responds only to specialty selective herbicides designed to reach both the root and leaf structures.

These sedge-specific products are formulated to eliminate nutsedge without damaging your surrounding turf, which is especially important for maintaining a healthy lawn in Tennessee’s climate. Timing also plays a critical role. Applications must be made when the weed is actively growing, and in some cases, follow-up treatments may be needed to fully disrupt its underground tubers.

Over-the-counter products often fail to deliver lasting results because they don’t target the plant deeply enough, or they may harm desirable grass in the process. At Second Nature, we apply professional-grade treatments with precision, ensuring long-term control that’s tough on nutsedge but easy on your lawn.

How Lawn Care Supports Weed Control

Weed control doesn’t happen in isolation—it’s directly impacted by the overall health of your lawn. Proper fertilization, consistent mowing, and seasonal treatments all contribute to dense, vigorous turf that naturally resists weed growth. Thin or stressed lawns leave openings where invasive species like nutsedge, clover, and crabgrass can take hold.

Second Nature’s lawn care programs are designed to strengthen your turf from the soil up. By promoting deeper roots and healthier blades, we reduce the conditions that allow weeds to thrive. When combined with targeted weed control treatments, a comprehensive lawn care plan provides long-term protection and a visibly better lawn.

Why Murfreesboro Conditions Make Weed Control Challenging

Middle Tennessee’s climate creates the perfect storm for weed pressure, especially from aggressive invaders like nutsedge. High heat and humidity accelerate growth cycles, allowing weeds to establish and spread quickly during the peak of summer.

In many Murfreesboro neighborhoods, heavy clay soils and poor drainage are common. These conditions hold excess moisture, which nutsedge thrives in, especially in low-lying areas or lawns with frequent irrigation.

While DIY treatments may seem like a quick fix, they often lead to overwatering or incorrect product use, which can weaken turf and give weeds an even greater advantage. The wrong approach can actually encourage more nutsedge growth rather than stopping it.

At Second Nature, we apply regionally tailored treatments built around Murfreesboro’s climate, soil conditions, and seasonal weed patterns. Our science-based strategies target the root of the problem—literally—and help restore balance to your lawn.

How Second Nature Treats Nutsedge and Lawn Weeds

At Second Nature, nutsedge and other persistent lawn weeds aren’t treated with a one-size-fits-all solution—we take a scientific, proactive approach tailored to the specific conditions of your lawn. That starts with a professional lawn evaluation, where we assess turf health, soil conditions, drainage issues, and existing weed pressure.

From there, we create a timing-based treatment plan designed to target weeds like nutsedge when they’re most vulnerable. Our team uses specialty herbicides formulated for sedges and other hard-to-kill species, applying them with the precision needed to protect your turf while eliminating the problem at the source.

But weed control doesn’t stop at spraying. We also address underlying soil conditions, adjust mowing height recommendations, and offer guidance on irrigation habits to prevent conditions that allow weeds to thrive in the first place.

With decades of experience treating lawns in Murfreesboro and throughout Middle Tennessee, we understand the unique challenges our climate presents—and we build every treatment strategy with those regional cycles in mind. The result? Long-term weed control backed by local expertise you can trust.

How to Prevent Nutsedge and Other Weeds From Coming Back

Controlling nutsedge is only part of the solution—keeping it from coming back requires consistent, science-backed lawn care practices that strengthen your turf and reduce weed pressure over time.

One of the most important steps is to avoid overwatering, especially in Murfreesboro’s heavy clay soils where moisture tends to linger. Excess water creates ideal conditions for nutsedge and other moisture-loving weeds to thrive. Improving soil drainage—either through aeration, grading, or soil amendments—can make a big difference in long-term weed prevention.

Proper mowing height also plays a critical role. When turf is kept too short, it becomes stressed and allows more light to reach weed seeds. Keeping your lawn at the recommended height helps protect its root system and shades out unwanted growth.

A dense, healthy lawn is your best defense. Thick turf naturally crowds out weeds, leaving less space for invasive species like nutsedge to take hold. Achieving that density requires a balanced lawn care program that includes seasonal fertilization, aeration, and consistent weed monitoring.

Second Nature’s ongoing lawn care services are designed to do exactly that—protect your lawn year-round with the right treatments, timing, and professional insight. We don’t just control weeds; we help your lawn outcompete them naturally.

What Is the Best Killer for Nutsedge?

The most effective treatments for nutsedge are selective sedge herbicides that target its unique structure without harming your lawn. These products are different from standard broadleaf weed killers and must be applied at the right time and rate. At Second Nature, we use professional-grade herbicides specifically designed for persistent weeds like nutsedge, ensuring long-term control and healthier turf.

How Long Does It Take for a Nutsedge Killer to Work?

With the right product and timing, visible results typically begin within 7 to 14 days. However, complete control often requires multiple applications depending on the severity of the infestation and the growth stage of the nutsedge. Our lawn care team monitors progress and applies follow-up treatments as needed.

Why Should I Not Pull Nutsedge?

Pulling nutsedge often makes the problem worse. This weed spreads through underground tubers, or “nutlets,” which easily break off and remain in the soil when hand-pulled. These nutlets regenerate and lead to even more growth. Proper control requires herbicides that reach the root system to prevent regrowth.

Why Does Nutsedge Keep Returning?

Nutsedge thrives in moist, compacted, or poorly drained soils, which are common in Middle Tennessee. Without addressing these underlying conditions—and without the right treatments—it often returns year after year. Ongoing lawn care and targeted weed control are essential for lasting results.

What Time of Day Is Best to Use Weed Killer?

Weed control products are most effective when applied during calm, dry conditions, typically in the morning or late afternoon when temperatures are moderate. Timing also depends on weather, lawn moisture, and the specific weed being treated. At Second Nature, we time each application based on conditions for the best possible results.

When Is the Right Time to Remove Weeds?

For most weeds, including nutsedge, the best time for control is during active growth, usually in late spring through summer. Treating at the right time ensures that the herbicide reaches the plant’s growing tissues and root systems. Our programs are designed to align with the natural weed cycles in Murfreesboro for the most effective control.

Take Control of Nutsedge With Local Expertise

Nutsedge may be one of the most persistent lawn weeds in Murfreesboro, but with the right approach and professional support, it’s entirely manageable. Effective control takes more than a quick spray—it requires expert evaluation, properly timed treatments, and a plan tailored to your lawn’s unique conditions.

Second Nature specializes in targeted weed control programs designed specifically for Middle Tennessee lawns. If you’re seeing signs of nutsedge or want to prevent future outbreaks, we’re here to help.
