For a local reference, Rancho In Bloom publishes the following sample frequencies for Temecula and Murrieta:

Rancho In Bloom sample frequencies (Temecula / Murrieta)

Turf with pop-up sprays	Spring: 2 days/week · Summer: 2 days/week · Fall: 1 day/week · Winter: Off in the sample
Shrubs with pop-up sprays	Spring: 2 days/week · Summer: 2 days/week · Fall: 1 day/week · Winter: Off in the sample
Moderate-water plants on drip	Spring: 2 days/week · Summer: 2 days/week · Fall: 1 day/week · Winter: Off in the sample

These are examples, not a prescription for every property. The guide explicitly calls for adjustments based on weather, soil, slope, equipment, and plants. Its winter shutoff assumes rainfall is meeting landscape needs; dry conditions may require supplemental irrigation. Rancho In Bloom: Sample Irrigation Schedules (https://ranchoinbloom.com/Watering-Guide/Schedules.php) Use the seasonal pattern as your starting point: review irrigation in spring, monitor it closely in summer, reduce it as conditions cool, and account for winter rainfall. Determine run times from your equipment's actual output and how water moves into your soil. A rotating nozzle and a fixed spray head should not automatically receive the same minutes. Keep separate settings for plantings with different needs. Newly installed plants also require an establishment plan rather than an established-yard schedule. Before selecting watering days, check the current guidance from the water provider listed on your bill. A ZIP code alone does not identify every property's provider.
