By Dennis Pittenger, University Of California Cooperative Extension

Wednesday, September 28th ~ 3:00 PM - 4:30 PM

Dennis Pittenger, University Of California Cooperative Extension

Course Description:

The ongoing drought demands greater landscape water conservation and landscape managers are facing a range of landscape watering restrictions. When water is limited, it is critical that landscape managers have the knowledge and skills to maintain landscape plant health and performance during drought. Participants in this workshop will learn how to prioritize and schedule irrigation, estimate minimum landscape water requirements, and apply cultural practices that conserve water.
