While summertime brings to mind lush greenery and warm sunshine, for many homeowners, it is also the time where lawn diseases start to happen. With stress from sunlight, drought, and higher foot traffic, it’s no wonder your lawn is more worn out than usual during the summer months. For many homeowners in Florida, telling the difference between lawn diseases can be a bit of a challenge. We’ve outlined the most common lawn diseases in Orlando and how to prevent them, so you can take your lawn back and enjoy the rest of your summer!

Brown Patch

Brown patch is a lawn disease that is very active in warm weather. Like the name suggests, this pathogen manifests as brown patches on your lawn on varying diameters. The circles will continue to grow until the disease is under control. Brown patch is one of the most common lawn diseases that most homeowners have seen at some point or another!

Summer Patch

Like Brown Patch, Summer Patch creates unsightly patches in the lawn that spread if left unchecked. This disease is most common in areas that get intense sunlight, and can appear once temperatures reach the 90-degree mark.

Dollar Spot

This disease gets its name from the size and shape of the spots that it leaves on lawns. This disease typically affects Kentucky Bluegrass species, and can usually be diagnosed by checking which species in grass mixes are affected by the pathogen.

Pythium Blight

Pythium Blight is one of the most destructive lawn diseases that attacks mature lawns and is common on athletic fields. Because of this disease’s preference for high moisture, poor drainage on your lawn can contribute to infection. The disease is particularly prevalent in hot weather with high humidity.

Disease Control

The key to controlling many of these lawn diseases is having the proper tools to fight them with. Fungicides and chemical treatments are particularly effective in treating these lawn ailments. To control these lawn diseases, there are many different fungicides you can use, including:

  • Azoxystrobin

  • Fenareimol

  • Propiconazole

  • Triophanate-methyl

Use caution when applying these fungicides and other chemicals to your property - especially if you have children or pets that play in the yard. At Evergreen Lawn and Pest Control, our highly-trained technicians can apply highly effective formulas that won't put your family at risk. 

Preventative Measures to Avoid Diseases

The best thing you can do to avoid diseases in your lawn is to take good care of it throughout the year. Preventative measures are always the most effective, so this includes:

  • Fertilizing your lawn at least 3-4 times a year (but not over-fertilizing).
  • Watering your lawn in the morning between 5 AM and 9 AM (this gives the water time to evaporate).
  • Mowing your grass using a high (3-4 inch) mowing setting.
  • Setting up an irrigation system- poorly drained lawns are more prone to disease.
  • Increasing air flow and nutrient intake through core aeration.

If you have noticed any of these symptoms or if you suspect disease in your lawn, don’t wait until it is a huge problem to address it. Here at Evergreen, we have the experience and tools necessary to get your lawn to a healthy state-- and keep it that way.
