How often should irrigation sprinkler zones be adjusted during the year?

Seasonal zone adjustments

Irrigation sprinkler zones should usually be adjusted several times a year to match changes in weather, plant growth, and sun exposure. In Dallas, spring, summer, and fall often require different watering schedules because heat, rainfall, and evaporation can change quickly.

Common times to adjust zones include:

• Spring: Increase watering gradually as temperatures rise and new growth begins.
• Summer: Check that each zone is delivering enough coverage during peak heat.
• Fall: Reduce watering as cooler weather and shorter days return.
• After landscape changes: Revisit zones if you add plants, regrade soil, or change turf areas.

It is also smart to inspect zones after heavy wind, drought restrictions, or unusually wet periods. A zone that worked well in one season may need different run times later to avoid dry spots or runoff.
