Occurs following winter snow melt

Long strips to irregularly shaped areas of dead grass often adjacent to paved driveways, sidewalks, street curbs, etc., where de-icing salts were applied

Color or dead grass typically is light tan to straw-colored; later turning dark brown

Usually a distinct boundary between affected and health plants

Occurs where spring snow melt water cannot freely drain from an area due to blockage along edges of curbs, driveways, or sidewalks

Occurs in open areas of the lawn where water goes through frequent freezing and thawing cycles during the snow melting process

Long strips to irregularly shaped areas of dead grass

Color of dead grass typcially is light tan to straw-colored; later turning dark brown

Usually a distinct boundary between affected and healthy plants

Occurs when temperatures are high (> 85°F) and little or no moisture is available through rain or irrigation for at least 2 to 3 weeks

General browning of entire turf grass area; may also look thin and dry

Affected areas may have clumps or tufts of green grass within areas of tan dry grass

Occurs often in sunny, exposed lawn areas but can occur in dry, shady areas as well

In most cases, cool season grasses will turn green and resume growth once cooler conditions and more frequent rainfall return

If heat and drought stress have been severe for several weeks, affected lawn areas may not recover or may only partially recover

Damage most commonly seen during July and August

Damaged areas yellow, then turning brown or straw-colored in small, irregular patches

Particularly common near sidewalks, driveways, and other sources of heat
