Does Your Artificial Turf Have Mold? Here’s What You Need to Know

Artificial turf has transformed how homeowners, landscapers, and contractors approach outdoor design. It’s durable, low-maintenance, and looks perfectly green all year long. But there’s one silent issue many turf owners don’t realize until it’s too late: mold and mildew.

Yes—mold can grow on artificial turf under the right conditions. And if left untreated, it can lead to odors, discoloration, and even surface deterioration. So, how can you tell if your turf has mold? And more importantly, how can you prevent it from happening in the first place?

Let’s take a closer look, beginning with prevention.

How to Prevent Mold on Artificial Turf

Prevention is the best defense when it comes to mold. Here are several proven ways to protect your turf:

1. Choose Turf with Built-In Protection

The most effective solution is to install artificial turf with antimicrobial protection—like Smart Turf with Microban®.

Microban® technology inhibits the growth of bacteria, mold, mildew, and odor by up to 99%, keeping your turf cleaner and fresher between cleanings. It’s built directly into the turf fibers during manufacturing, meaning it never washes off or wears away. Plus, Microban is EPA-regulated, ensuring it meets strict safety and performance standards.

2. Ensure Proper Drainage

Always make sure your turf installation includes a permeable backing and a well-graded base. This allows water to flow through easily and prevents pooling.

3. Regular Cleaning

Rinse your turf regularly, especially in humid climates. Remove debris, pet waste, and dirt using a leaf blower, rake, or turf brush. For deep cleaning, use a turf-safe disinfectant or mild soap solution.

4. Improve Airflow and Sunlight Exposure

Trim overhanging branches or reposition lawn furniture to reduce shaded areas. Increased sunlight helps dry out moisture faster, making it harder for mold to survive.

5. Use Odor and Bacteria Control Products

For extra protection, turf-safe antimicrobial sprays can be used periodically. However, these are supplemental—nothing beats the continuous protection of turf embedded with Microban® technology.

Why Microban® Is a Game-Changer for Mold Prevention

Unlike surface-level treatments that wear off, Microban® antimicrobial technology is built into Smart Turf during the manufacturing process. It continuously disrupts the growth of microorganisms that can cause mold, mildew, and odors.

Benefits of Microban® Protection:

  • 24/7 protection: Works continuously to inhibit microbial growth

  • Long-lasting: Integrated during manufacturing; won’t fade or wash off

  • Odor control: Keeps turf smelling fresh, even in high-traffic or pet areas

  • EPA-regulated: Meets safety standards for residential and commercial use

 

What Causes Mold on Artificial Turf?

Artificial turf itself doesn’t “feed” mold the way organic materials do. However, the environment around and beneath your turf can create a breeding ground for mold, mildew, and bacteria. Here are the most common culprits:

Water pooling on artificial turf due to poor drainage

1. Poor Drainage

Water is mold’s best friend. When artificial turf isn’t installed with proper drainage, moisture can become trapped beneath the surface. Over time, this standing water creates a damp, dark environment where mold can thrive.

2. Organic Debris

Leaves, pollen, and soil particles that accumulate on turf act as organic material that mold can use as a food source. If you don’t regularly remove debris, you’re giving mold exactly what it needs to grow.

3. Pet Waste

Pet urine and feces introduce bacteria and moisture into the turf fibers. Without proper cleaning, this combination promotes bacterial growth and foul odors—and can encourage mold and mildew formation in shaded or poorly ventilated areas.

4. High Humidity or Shade

Areas that stay moist—like those under trees, near sprinklers, or in humid climates—are more prone to mold growth. Without sunlight to dry things out, spores can take hold and spread quickly.

How to Identify Mold on Artificial Turf

Mold on artificial grass can look deceptively similar to dirt or algae buildup. Here are some warning signs to watch for:

  • Discoloration: Yellow, green, or black patches on the turf surface

  • Slimy or fuzzy texture: Especially in areas that stay wet or shaded

  • Persistent odor: A musty, earthy smell is a strong indicator of mold or bacterial growth

  • Soft or degraded infill: Excess moisture can cause infill to clump or break down, signaling trapped water underneath

If you notice these signs, your turf may already be compromised.

What Happens When Mold Grows on Turf?

While mold might seem like a minor inconvenience, it can lead to several serious issues—both for your turf and your health.

Turf Deterioration

Mold can break down infill materials and adhesives over time. This can lead to lifting seams, uneven patches, and reduced surface lifespan.

Odor and Air Quality Issues

Mold and mildew produce volatile organic compounds (VOCs) that create unpleasant odors. In outdoor living areas, this can make your yard less enjoyable and even impact indoor air quality if close to windows or doors.

Health Concerns

Prolonged exposure to mold spores can cause respiratory irritation, allergies, and skin reactions—especially for children, pets, and individuals with asthma.

Increased Maintenance Costs

Once mold sets in, removal can be labor-intensive and costly. Cleaning, disinfecting, and re-leveling infill can quickly add up—making prevention a far better (and cheaper) option.

Expert Insight: Why Mold Prevention Matters

Mold prevention isn’t just about aesthetics—it’s about longevity and safety. According to the Centers for Disease Control and Prevention (CDC), exposure to mold can lead to allergic reactions, respiratory irritation, and other health issues in sensitive individuals.

By choosing Smart Turf with Microban® antimicrobial protection, you’re not just investing in a greener lawn—you’re protecting your family, pets, and property value.

Frequently Asked Questions (FAQ)

1. Can mold grow under artificial turf?

Yes. Mold can form beneath turf if water becomes trapped in the base layer or infill. Proper drainage and antimicrobial turf help prevent this issue.

2. How do I clean mold from artificial turf?

Use a mixture of water and mild detergent, or a vinegar solution. Scrub the affected area gently, rinse thoroughly, and allow it to dry completely. For recurring issues, consider upgrading to Microban®-protected turf.

3. Will pet urine cause mold?

Pet urine introduces moisture and bacteria, which can contribute to mold growth over time. Turf with Microban® protection helps neutralize odors and prevent bacterial buildup.

4. How often should I clean my turf to prevent mold?

In most climates, rinsing every 1–2 weeks and deep cleaning every few months is sufficient. In humid or shaded areas, increase cleaning frequency.

5. Is Microban® safe for children and pets?

Yes. Microban® technology is EPA-registered and rigorously tested for safety. It provides an added layer of protection without affecting the turf’s texture, appearance, or performance.
