Cycle Irrigation

irrigationReduces runoff and water loss, & creates more drought-tolerant lawns.

Longmont's clay soils can only absorb a limited amount of water at one time. Cycle irrigation reduces runoff and allows more water to be absorbed, resulting in deeper root growth and more drought-tolerant lawns.

Cycle irrigation uses multiple start times, running through a multiple cycle of zones more than once per day. For example, instead of watering an entire zone for 20 minutes, set up three start times of 6 minutes each for a total of 18 minutes or two start times of 10 minutes each for a total of 20 minutes. Set start times so that there is an hour in between cycles, and adjust the length of time you water each zone so that no runoff occurs.
