Preventing Lawn Fungus: Fix the Culture, Not Just Spray

Brown patch and other lawn fungi stem from poor management: too much shade, standing water, overwatering, overfertilizing, and incorrect mowing height. Fungicides are a band-aid. Match your grass type and maintenance to the site conditions, and disease problems largely disappear. Consult the lawn maintenance calendars at xrl.us/LAWNCALENDAR for species-specific guidance.
