What is Summer Patch?

Summer patch is a root disease that commonly affects lawns with Kentucky bluegrass and fine fescue grasses. As the fungus responsible for the disease invades the lawn's roots, circular patches, around 2 - 3 inches in diameter, will begin to appear. They often start as a yellow color, turning straw-brown as the lawn disease causes the grass plant to die, and can spread to be as large as 12 inches in diameter.

Conditions Favoring the Disease 

Summer patch often occurs in mid-summer when wet weather or heavy irrigation are followed by extended periods of high temperatures exceeding 82˚F. Lawns that are shaded, have poor drainage, or are compacted have a much higher chance of suffering from the disease.

Management

Cultural practices that promote positive root growth, such as aeration, help to improve drainage on lawns suffering from compaction. Additionally, raising the height of your mower blade may lessen the extent of summer patch injury.
