Irrigation Trials

After being grown for a full year on a regular watering regime to establish deep, healthy roots, plants are irrigated through the second growing season with one of three different irrigation frequencies that correspond to the Water Use Classification of Landscape Species categories of Low, Moderate, and High.  (These categories are based on percentages of reference evapotranspiration with local weather station data used to estimate these percentages.)

 Height and width are measured monthly to calculate a growth index for each species at each irrigation level. Overall appearance, flowering time and duration, and pest or disease problems are rated monthly to provide a comprehensive assessment of performance, allowing us to make irrigation recommendations for these plants. This data allows growers to provide good information in marketing their product to the consumer.
