For a scholarly approach to "Making Sense of ET Adjustment Factors for Budgeting and Managing Landscape Irrigation" , see https://ucanr.edu/sites/UrbanHort/files/217692.pdf For a simpler, real-world explanation of all that, listen to this episode of Davis Garden Show. In addition to water use coefficients for landscape shrubs, Don Shor and Lois Richter talk about selecting vines and (as always!) when to plant tomatoes, peppers, and other vegetables.

Don and Lois talk about a wide variety of Spring gardening topics! Starting off with a mention of the warm weekend temperatures forecast, and about the latest update regarding California's ongoing drought, two years running. Today, the statewide figures are updated showing our region in "extreme drought" due to the low rainfall during our "typical" rain season September - March. Don talks about how this can especially impact our trees and other plants, and gives some watering advice. And of course, a return to the frequently asked questions such as: When is it best plant tomatoes? Mid-April! The Davis Garden Show airs live on KDRT 95.7 FM each Thursday noon - 1 PM, and replays Saturday monings 9 - 10 AM.
