Abstract

Liners of Juniperus horizontalis Moench ‘Wiltonii’, Ilex crenata Thunb. ‘Rotundifolia’, Rhododendron × L. ‘Hershey's Red’, Pyracantha × M.J. Roem ‘Teton’, and Photinia × fraseri Dress were grown to saleable size in 3.1 1 (1 gal) containers. Plant water consumption was measured during 336 days from June 24, 1986, to June 19, 1987. Pyracantha consumed the most water (50.4 1 (13.3 gal)/plant) while photinia consumed the least water (37.8 1 (10.0 gal)/plant). Based on the increase in growth index per liter of water consumed, photinia used water most efficiently. Growth index, pan evaporation, or growth index and pan evaporation were the best predictors of plant water use.
