Irrigating Sloped Areas The High Desert varies greatly in elevations and many homes have slope areas. Proper landscaping can keep slopes from sliding or eroding. Planting on sloped areas requires a specialized approach to irrigation and a selection of suitable plants.
Drip irrigation is the most water efficient and it also:
Keeps weeds down by putting water only at the roots of desired plants
Lessens erosion from run-off caused by sprinkler systems
Can be placed and moved on difficult sloped areas
Trees and shrubs in containers planted on slopes should be watered using drip emitters.
