Seasonal Irrigation Schedule
Summer Schedule (Critical Window)
Peak HeatLevel 1 Drought Watch rules: Limit watering to 3 days per week (up to 10 minutes per station). No watering between 10 a.m. and 6 p.m. No watering during rain or 48 hours after.
Spring & Fall Schedule
Same 3 days per week schedule applies.
Winter Schedule
1 to 2 days per week recommended during cooler, damp months.
Water Waste Fines & Enforcement
Administrative fines start at $100 and escalate to $250 and $500 for uncorrected water waste.
San Diego Soil & Microclimate Strategy
San Diego's coastal humidity creates high disease pressure (dollar spot, brown patch) on warm summer nights. Fast-draining coastal sand leaches nitrogen quickly; light, frequent feeding and morning irrigation are required.
