Frequently Asked Questions

Have questions about lawn disease control? We've got answers.

How do I know if my lawn has a disease or just needs water?

Drought stress typically affects the entire lawn uniformly, while diseases create distinct patches or patterns. Disease-affected grass often shows discoloration, unusual growth, or powdery substances. If watering doesn't improve the condition within a few days, or if patches are spreading, it's likely a disease requiring professional diagnosis.

How long does it take to see results after treatment?

Fungicide treatments typically stop disease spread within 3-7 days. Visible recovery of the grass depends on the severity of damage and the specific disease. Minor cases may show improvement in 2-3 weeks, while severe infections may take 4-8 weeks for full recovery. In some cases, reseeding affected areas may be necessary.

Are the fungicides safe for pets and children?

Yes, we use professional-grade fungicides that are safe for pets and children once the application has dried, typically within 2-4 hours. We follow all safety guidelines and provide specific instructions for each treatment. Always keep pets and children off the lawn until the product has completely dried.

Will the disease come back after treatment?

Diseases can recur if the underlying conditions that caused them aren't addressed. That's why our treatment includes cultural corrections and a prevention plan. With proper lawn care practices, regular monitoring, and preventive treatments when conditions favor disease, recurrence can be significantly reduced or eliminated.

Can I treat lawn disease myself with store-bought products?

While consumer fungicides are available, professional treatment is more effective. We accurately diagnose the specific disease, use commercial-strength products not available to consumers, and apply them with professional equipment for better coverage. Incorrect diagnosis or treatment can waste money and allow the disease to spread further.

How much does lawn disease treatment cost?

Cost varies based on lawn size, disease severity, and number of treatments required. Minor cases may need one treatment, while severe infections might require multiple applications. Contact us for a free inspection and quote. Early treatment is always more cost-effective than waiting for the disease to spread.

Should I continue mowing during disease treatment?

Yes, but with precautions. Continue mowing at the proper height, but avoid mowing when the grass is wet as this can spread disease spores. Clean your mower blades after mowing diseased areas to prevent spreading to healthy parts of the lawn. We'll provide specific mowing guidelines with your treatment plan.

What causes lawn diseases to develop?

Lawn diseases are caused by fungi that thrive in specific conditions: excessive moisture, poor air circulation, improper mowing, over-fertilization, thatch buildup, and stressed grass. Richmond Hill's humid summers and wet springs create ideal conditions for many lawn diseases. Proper lawn care practices significantly reduce disease risk.
