How To Get Rid Of Dollar Spot
Dollar Spot is a common lawn disease that can be frustrating for homeowners who want a lush, green yard. Understanding how to identify and treat this issue can make a big difference. Let’s break down the best ways to tackle Dollar Spot effectively.
What is Dollar Spot?
Dollar Spot is a fungal disease caused by the pathogen *Sclerotinia homoeocarpa*. It manifests as small, round patches of light brown grass that can resemble the shape of a silver dollar. These patches can vary in size but often expand if not treated promptly.
The key signs of Dollar Spot include:
- Small, circular patches of brown grass.
- White mycelium in the early morning dew.
- Thinning areas in your lawn, especially in hot, humid weather.
Recognizing these signs early can help you take preventive measures before the issue spreads.
Causes of Dollar Spot
Understanding what causes Dollar Spot is crucial for effective treatment. Some common factors contributing to this disease include:
- High humidity and warm temperatures.
- Poor lawn care practices, such as inadequate watering or mowing.
- Nitrogen-deficient soil.
These conditions create a perfect environment for the Dollar Spot fungus to thrive, making it essential to address them.
Preventing Dollar Spot
Prevention is always better than a cure. Here are some proactive steps to keep Dollar Spot at bay:
1. Maintain Proper Watering
Water your lawn early in the morning. This allows the grass to absorb moisture before the heat of the day. It also reduces the amount of standing water, which can encourage fungal growth.
2. Fertilize Appropriately
A balanced nitrogen fertilizer can help strengthen your grass and make it more resilient against diseases. It’s important to test your soil to determine the right amount of nutrients needed.
3. Mow Regularly
Keeping your grass at the right height is crucial. Generally, maintain a mowing height of about 2.5 to 4 inches. This encourages deeper roots and healthier grass.
4. Improve Air Circulation
Trim back shrubs or trees that may be blocking sunlight and airflow. A well-ventilated lawn is less likely to suffer from fungal infections.
Treating Dollar Spot
If Dollar Spot has already invaded your lawn, don’t worry; there are effective treatments available.
1. Chemical Treatments
Fungicides can effectively combat Dollar Spot. Look for products containing active ingredients like propiconazole or chlorothalonil. Apply these according to the label instructions for the best results.
2. Natural Remedies
For those who prefer a more organic approach, consider using a mixture of baking soda and water. Mix one tablespoon of baking soda with one liter of water and spray it on the affected areas. This can help control the fungus.
3. Increase Lawn Maintenance
Enhance your lawn care routine by aerating the soil and dethatching as needed. This promotes healthy grass growth and reduces the risk of disease.
Identifying Infected Areas
Spotting the infected areas quickly is essential. Regular checks can help you detect any unusual patches early.
Look for areas where growth seems stunted or uneven. Use a soil test kit to check for nutrient deficiencies that may be contributing to the problem.
Signs of Recovery
Once you start treating Dollar Spot, look for signs that your lawn is recovering. Healthy grass should start to regrow in the affected areas.
Notice the following:
- Green shoots emerging from the brown patches.
- Less visible mycelium or signs of fungal growth.
- Improved overall lawn density.
Long-Term Lawn Care Practices
Once you have dealt with Dollar Spot, focus on long-term care to prevent recurrence.
1. Soil Testing
Regular soil testing can help you maintain optimal nutrient levels. This ensures your lawn remains healthy and resistant to diseases.
2. Regular Aeration
Aerating your lawn at least once a year helps improve soil structure. This promotes deeper root growth and better water absorption, making your lawn less susceptible to diseases.
3. Seasonal Fertilization
Fertilizing your lawn according to the seasons supports healthy growth. Use a slow-release fertilizer in the spring and a balanced fertilizer in the fall.
4. Monitor Environmental Conditions
Pay attention to weather patterns. During periods of high humidity and temperature, increase your lawn care efforts to prevent Dollar Spot.
Dealing with Dollar Spot can be frustrating, but with the right strategies, you can protect your lawn and promote a healthy, lush appearance. Remember that prevention is key. By maintaining healthy soil, proper watering, and mowing practices, you can significantly reduce the chances of this disease returning. If Dollar Spot does appear, act quickly with the appropriate treatments to ensure your lawn remains vibrant and green.

Frequently Asked Questions
“`html
What are the symptoms of Dollar Spot on grass?
Dollar Spot typically appears as small, round, tan to brown patches on grass. Each spot can range from a few inches to several feet in diameter. Affected grass may show yellowing before dying, and the patches can merge together, creating larger areas of damage. The fungal disease is most noticeable during warm, humid weather, particularly in late spring to early summer.
How does watering affect Dollar Spot severity?
Watering can significantly influence the severity of Dollar Spot. Inadequate watering stresses the grass, making it more susceptible to disease. Conversely, excessive moisture, especially from frequent light watering, promotes fungal growth. It’s best to water deeply and infrequently, allowing the grass to dry out between watering sessions. This approach helps strengthen the grass and reduce the likelihood of Dollar Spot.
Can fertilization help in managing Dollar Spot?
Yes, proper fertilization plays a crucial role in managing Dollar Spot. Lawns that receive balanced nutrients tend to be healthier and more resilient against diseases. Applying fertilizers high in nitrogen during the active growing season can help the grass recover from stress and resist fungal infections. However, avoid over-fertilizing, as this can lead to lush growth that is more prone to diseases.
What are the best cultural practices to prevent Dollar Spot?
Implementing good cultural practices is key to preventing Dollar Spot. Regularly mowing the grass at the appropriate height helps promote air circulation and sunlight penetration, reducing humidity levels. Additionally, maintaining proper soil moisture, aerating the lawn, and practicing crop rotation can improve grass health and minimize the chances of infection.
Is Dollar Spot treatable with fungicides?
Fungicides can effectively treat Dollar Spot, especially when applied at the first signs of the disease. Look for fungicides that specifically target the pathogens responsible for Dollar Spot. However, it’s important to combine chemical treatments with cultural practices for the best results. Always follow the product instructions for application rates and timing to ensure effectiveness.

Final Thoughts
To get rid of dollar spot, start by maintaining a healthy lawn through proper mowing, watering, and fertilization. Implementing these practices can help restore your grass and prevent the disease from returning.
Consider applying fungicides if the problem persists, targeting the affected areas specifically. Regularly aerate your lawn to improve drainage and reduce compaction, which can exacerbate dollar spot conditions.
Lastly, ensure your grass type is suitable for your region, as some varieties are more resistant to this issue. By following these steps, you can effectively combat dollar spot and keep your lawn thriving.
