WateringTimes turns California water rules into yard-level math
A California-only reference site for supplier watering schedules, plant needs, sprinkler run times, landscape budgets, and turf-replacement rebates.
Field notes
WateringTimes separates supplier rules from city names because watering restrictions can change at the water-district boundary. Its plant calculations use WUCOLS IV across all six California climate zones, while the landscape budget tool compares gallons with the state cap for new planting. The homepage lists 4,103 plants, 676 reference-climate cities, 18 supplier rulebooks, six landscape-rule explainers, and five rebate programs. It says the calculators expose their arithmetic and decline to fill unreadable source fields by guesswork.
