Steep slopes with south and west exposures require more frequent water to maintain the same plant cover as east or north slopes. Terracing slopes reduces runoff. Limit irrigated bluegrass turf to small or heavily used areas. Soil preparation is a key to water conservation. Proper irrigation practices and system design can lead to 30 to 80 percent water savings.
Mulches help reduce water needs and control weeds.
The need for landscaping to conserve water received new impetus following the drought of 1977 throughout the western states and the recognition that nearly 50 percent of the water used by the average household is for turfgrass and landscape plantings. This practice is not only self-defeating as far as water conservation is concerned, it also produces damaging effects to trees and shrubs. It is not xeriscaping. Whether you want to redesign an old landscape or start fresh with a new one, a plan is a must. The plan does not have to be elaborate but should take into consideration the exposures on the site.
