What Causes Fungus on Grass?

Over-watering: One of the primary contributors to fungal growth is excess moisture. Watering too often, especially during the evening or night, leaves grass wet for extended periods, creating an ideal environment for fungi to thrive.

Poor soil drainage: If your lawn has compacted or poorly draining soil, water can accumulate on the surface or in the root zone. This stagnant water is a breeding ground for various types of fungus.

Humidity and warmth: Many types of fungi thrive in warm, humid conditions. Lawn fungi are most active in the spring and summer, especially when the weather is damp or when there's prolonged rain.

Improper lawn care: Over-fertilizing or mowing too short can stress the grass, making it more vulnerable to fungal diseases. Additionally, poor aeration can limit air circulation, trapping moisture and encouraging fungi to develop.

Common Types of Fungus on Grass

There are several types of fungal diseases that commonly affect lawns. Each type of fungus has unique symptoms, but they all share the potential to cause damage to your grass if not controlled. Here are the most common fungi that affect lawns:

Dollar Spot
Dollar spot is a common lawn disease that causes small, round patches of light-colored, dead grass. These patches are usually about the size of a silver dollar and may expand over time if the disease isn’t treated. Dollar spot thrives in areas with dry soil and high humidity, and it typically appears during the warmer months.

Brown Patch
Brown patch is one of the most damaging lawn diseases, causing large, irregular patches of brown or dead grass. It often has a yellowish border around the affected area. Brown patch thrives in hot, humid conditions and is typically caused by excessive moisture, such as over-watering or prolonged rainfall. It can spread quickly if not managed properly.

Powdery Mildew
Powdery mildew is characterized by a white, powdery coating on grass blades. It typically occurs in shaded areas where moisture is trapped. While powdery mildew doesn’t often kill grass, it weakens the plants, making them more vulnerable to other diseases and environmental stress.

Rust
Rust fungus causes orange or yellow pustules on grass blades, which can spread across the lawn. The grass may also become weak and thin. Rust is most common in lawns that are stressed, such as those with poor soil or inadequate nutrition. Rust fungus thrives in cool, wet conditions, making it more likely to appear in early spring or late fall.

Red Thread
Red thread is a fungal disease that produces pinkish-red or orange threads on grass blades. It typically affects lawns with low nitrogen levels and is most common in cooler, damp conditions. Although red thread doesn’t usually kill grass, it can weaken it, making it more susceptible to other pests or diseases.

How to Identify Fungus on Grass

Detecting fungus on grass early is key to minimizing damage to your lawn. If you notice any of the following symptoms, your lawn may be suffering from a fungal infection:

Discolored patches: Fungal diseases cause irregularly shaped patches of discolored grass, often turning yellow, brown, or gray. These patches may begin as small spots but can spread and merge over time.

Circular or irregular patterns: Many types of fungi, like brown patch and dollar spot, create round or irregularly shaped patches that grow outward. These patches may be surrounded by yellow or wilted grass.

White, powdery growth: Powdery mildew presents as a white, powdery film on the surface of grass blades. It may cover large sections of the lawn, particularly in shaded areas with poor air circulation.

Orange or reddish spots: Rust fungus causes orange, yellow, or red pustules to form on the grass blades. These pustules may burst, leaving behind rust-colored stains.

Thin, weak grass: Fungal diseases often weaken the grass, causing it to become thin and spindly. Affected grass may die off in patches, leading to a patchy lawn.

The Effects of Fungus on Grass

Fungal infections can have a wide range of effects on your lawn, depending on the severity of the infection and the type of fungus involved. Some of the most common effects include:

Weakening the grass: Fungal diseases weaken the grass by affecting its roots, leaves, or both. This makes it harder for the grass to absorb nutrients and water, leaving it more susceptible to other stressors like drought or pests.

Dead patches: Many fungal diseases, such as brown patch and dollar spot, kill grass in infected areas, creating unsightly brown or dead patches in your lawn. These areas can be difficult to repair if the fungus spreads unchecked.

Reduced lawn vigor: Even if the fungus doesn’t kill the grass, it can significantly weaken the lawn’s overall health. A stressed lawn may have a diminished ability to recover, grow, and resist future diseases.

Spread to neighboring areas: Fungal spores can easily spread from one part of the lawn to another, or even to neighboring lawns. This makes it important to treat fungal infections quickly to prevent widespread damage.

How to Treat Fungus on Grass

If you’ve identified fungus on your lawn, it’s important to act quickly to prevent the disease from spreading. Here are some steps you can take to treat fungal infections on your grass:

Improve Lawn Care Practices

Watering: Adjust your watering schedule to prevent excessive moisture. Water early in the day, and avoid watering in the evening or late afternoon, as this leaves grass wet overnight, creating an ideal environment for fungus.

Mowing: Mow your lawn regularly, but avoid cutting the grass too short. Short grass is more vulnerable to disease. Be sure to remove clippings after mowing, as they can spread fungal spores.

Aeration: Aerate your lawn to improve drainage and promote better air circulation. This helps prevent water from stagnating and encourages stronger, healthier grass.

Fertilizing: Use a balanced fertilizer to promote healthy grass growth. Avoid over-fertilizing with nitrogen, as this can stimulate rapid growth that is more susceptible to fungus.

Apply Fungicides

If fungal growth persists despite your best efforts, consider applying a fungicide. Fungicides are available in both chemical and organic forms, and many are effective in controlling a wide range of lawn fungi. Be sure to choose a fungicide that is specifically designed for the type of fungus affecting your lawn. Follow the manufacturer’s instructions for safe and effective application.

Reseed and Repair Damaged Areas

In cases where the fungus has caused significant damage, reseeding may be necessary to restore the affected areas. Choose grass seed that is resistant to the type of fungus in your area, and follow proper lawn care practices to help prevent future outbreaks.

Improve Soil Drainage

If your lawn is prone to fungal infections due to poor drainage, consider improving the soil structure. Aerating the lawn, adding organic matter, or installing a drainage system can help water drain more effectively, reducing the moisture that fungi thrive in.

Preventing Fungus on Grass

Preventing fungus on grass is much easier than treating it after the fact. By following these best practices, you can help minimize the risk of fungal infections:

Water correctly: Water deeply but infrequently, allowing the soil to dry out between waterings. This reduces the amount of moisture available to fungi.

Mow properly: Maintain the appropriate grass height for your lawn type. Regular mowing helps prevent thatch buildup, which can trap moisture and contribute to fungal growth.

Choose disease-resistant grass varieties: When planting or reseeding your lawn, select grass types that are resistant to fungal diseases. This is especially important in areas prone to certain types of lawn fungi.

Apply preventive fungicide: If you live in an area with a high risk of fungal infections, you may want to apply a preventive fungicide to your lawn during the growing season.
