Sprinkler Schedule Builder by Zone and Grass Type

Quick Answer

Build a sprinkler schedule around 2-3 deep waterings per week that together deliver about 1-1.5 inches, confirmed with a simple catch-cup test rather than guessing at run times.

Start With a Catch-Cup Test

Before setting run times, confirm how much water your system actually delivers. Place several shallow, straight-sided containers (tuna cans work well) around each zone, run the sprinklers for 15 minutes, then measure the depth collected. That gives you a real inches-per-minute rate to build a schedule around, instead of guessing.

Building the Schedule

Sloped or clay soil?

If water runs off before soaking in, split each zone's run time into two shorter cycles with a 30-60 minute gap between them ("cycle and soak") rather than one long continuous run.

Adjusting the Schedule by Season

Reduce frequency in spring and fall as rainfall and cooler temperatures reduce demand, and pause or minimize watering in winter for most grass types during dormancy. See our watering frequency guide for the seasonal breakdown.

Frequently Asked Questions

It depends on your system's output rate, but a common starting point is 20-30 minutes per zone, 2-3 times a week — then adjust based on a catch-cup test to confirm actual output.
