Irrigation Tips for Hot Summer Days

Hot Weather Calls for Irrigation Efficiency

With the extended periods of hot, dry weather we have been experiencing during the summer, outdoor water use is likely to increase. In fact, according to the City of Corvallis, single family residential customers use 46% more water in the summer than in the winter. These water conservation tips can keep lawns and gardens healthy while reducing costs and unnecessary losses.

1. Water early (before 10 am) or late (after 6 pm) to limit evaporative losses.
2. Water deeply once or twice a week to encourage deep root growth. Avoid puddling.
3. Increase mowing height. Grass that’s about 2.5 to 3 inches tall will shade roots and reduce evaporation.
4. Adjust watering frequency based on weather conditions. Water more frequently when it is hot and dry, and less frequently when it is cooler and wetter.
5. Water close to the ground. Drip irrigation systems are very efficient because they help avoid losses caused by misting, overspray, and runoff. Learn more about watering systems.
6. Choose water-efficient plants. Conserve water in your landscape by using native and drought tolerant plants. For assistance with your plant materials selection, the award-winning guide, Water-efficient Plants for the Willamette Valley, is available online from the City of Corvallis.
