Group together plants having similar irrigation requirements. Minimize irrigation runoff and encourage deep rooting by proper soil preparation to absorb and drain water. Mulch to minimize evaporation and runoff. Use of ground plants to minimize evaporation losses. Reduce runoff by minimizing use of artificial slopes and by terracing natural or cut slopes.
Different soils have different watering needs.
Most soils require deep and infrequent watering. However, the quick draining nature of sandy soils necessitates more frequent but shorter waterings with good mulching to prevent evaporation. Additional watering in sandy soil will only feed the water table. Temporary irrigation systems are recommended until new plants become established. Site the system to avoid watering walks, driveways and streets.
