Dollar spot lawn disease is a common and damaging fungal problem that can ruin your lawn if not treated. It’s called “dollar spot” because it creates small, round, silver dollar-sized patches on the grass, making your lawn look patchy and unattractive. While it might seem like a minor issue at first, dollar spot can quickly spread and kill large areas of grass if not properly managed.
To keep your lawn looking green and healthy all season, it’s important to know how to spot, treat, and prevent dollar spot disease. Additionally, it’s crucial to be aware of other lawn issues, such as Red Thread Lawn Disease, which can also affect the appearance and health of your grass.
This article covers everything you need to know about dollar spot, from what causes it and how to identify it, to the best ways to get rid of it. Whether you’re experienced with lawn care or just starting out, this guide will help you maintain a beautiful lawn.
What Causes Dollar Spot Lawn Disease?
Dollar spot lawn disease is caused by a fungal pathogen known as Clarireedia jacksonii. This fungus thrives in environments where conditions are warm, humid, and nitrogen-deficient, making lawns more susceptible during the growing season.
Typically, dollar spot becomes active in late spring and persists through the fall, especially in regions where moisture levels are high. The disease spreads through spores that are easily carried by wind, water, and even lawn equipment, making it difficult to control once it takes hold.
How to Control and Treat Dollar Spot Lawn Disease?
When it comes to treating dollar spot, fungicides are the most effective option. However, it’s important to choose the right product and apply it correctly to achieve the best results. Among the various fungicides available, Patch Pro stands out as a top choice for both preventative and curative treatments.
How to Apply Patch Pro
Preparation: Before starting any treatment, ensure you’re wearing appropriate personal protective equipment (PPE) and that the lawn is clear of people and pets.
Mixing: For preventive treatment, mix 0.5 ounces of Patch Pro per 1,000 square feet of lawn with enough water to thoroughly cover the area. For active infections, use 2 ounces per 1,000 square feet.
Application: Use a 1-gallon hand pump sprayer for localized treatment. Apply the mixture evenly over affected areas, making sure to cover surrounding grass to prevent further spread.
Timing: Apply the treatment early in the morning or late in the afternoon when temperatures are cooler. Make sure the grass is dry before application, and avoid mowing for at least 24 hours after treatment.
Follow-Up: Reapply Patch Pro 14 to 28 days after the initial treatment, especially if conditions remain favorable for dollar spot development.
Note on Safety
After using Patch Pro, make sure to keep people and pets off the treated areas until the lawn is completely dry. This usually takes about 24 to 48 hours, depending on the weather and how wet the ground is. Waiting until the area is dry helps keep everyone safe from the chemicals and makes sure the treatment works well.
Preventing Dollar Spot Lawn Disease
Preventing dollar spot is easier and more affordable than dealing with it later. By following these simple tips, you can keep your lawn healthy and avoid the hassle of fighting this common disease:
Fertilize Regularly: Use slow-release nitrogen fertilizer throughout the growing season to keep your grass strong and less likely to get sick.
Mow Smart: Cut your grass to the right height (3-4 inches) and never remove more than one-third of the blade at once to avoid stressing the lawn.
Water Wisely: Water your lawn deeply but only a few times a week, ideally in the early morning, so the grass dries during the day and stays healthy.
Manage Thatch: Aerate your lawn to break up thatch, the layer of organic material, so your lawn can absorb nutrients better and stay disease-free.
Check Soil pH: Test your soil’s pH annually and adjust it as needed to keep it balanced and your grass healthy.
Improve Airflow: Trim overhanging trees and bushes to allow more air circulation and help your lawn dry out quickly after rain or watering.
Consider Fungicides: In areas where dollar spot is a yearly problem, apply a preventive fungicide in the spring to stop the disease before it starts.
