LinkedInEstimating landscape irrigation needs
Our office has recently been receiving calls about water bills and landscape plants. The rising cost of water will only continue to influence plant choices as we move forward.
UC’s A Guide to Estimating Irrigation Water Needs of Landscape Plantings in California: The Landscape Coefficient Method and Water Use Classification of Landscape Species is a helpful resource and can be accessed online in its entirety.
Color photos, tables, and fully explained formulas can be found throughout this highly organized 160 publication. Chapters include:
- Estimating water requirements for crops and turf
- Estimating water needs for landscape plantings
- Using the landscape coefficient formula
- Using the landscape coefficient to estimate landscape evapotranspiration
- Irrigation efficiency and calculating the total amount of water to apply
- Putting it all together: A worksheet for calculations
- Using water estimates in landscape planning and management
- Special planting situations
