A drip irrigation system is perfect for Arizona customers. These should run longer than sprinklers because they provide a slow water delivery for your plants. Usually, you want to stick with:
Two times a week in fall & spring
Every other day in summer
Once a week in winter
When it comes to how long should you run your drip irrigation system, here is what we suggest:
High-flow emitter ~20 GPH: 12 minutes
Low-flow emitter ~4 GPH: 30 minutes
Low-flow emitter ~2 GPH: 60 minutes
Low-flow emitter ~1 GPH: 90 minutes
