Symptoms

Dry spots may develop where turf is not getting enough water. Areas with too much water may become scalded or scorched if drainage is poor and temperatures are high. Overwatering or waterlogged areas also lead to root pathogen problems and invasion by certain weed species.

Prevention and management

Check sprinklers for broken heads. Fix or replace as needed. Perform a "can test" on your lawn to check your sprinkler output. Make sure you are getting uniform coverage. Follow recommended watering procedures and schedules. Where poor drainage occurs, aerate or consider renovation.
