Description

Using plant species that require less water is one important principle of XeriscapingTM. However, little research has examined the water requirements of complete landscapes differing only in plant material. Nine landscapes were installed in drainage Iysimeters with three classes of plant material: mesic, mixed and xeric. Each plot was divided into woody plant, turf, and perennial hydrozones and water balances for each hydrozone were developed. Overall landscape coefficients (KL) ranged from 0.6 to 0.8 for the three landscape treatments. For woody plants and perennials, the relationship between crop coefficient (Kc) and percent canopy cover was the key determinant of water use under well-watered conditions.
