Grass is best watered with sprinklers. Trees, shrubs, garden flowers, and groundcovers can be watered with drip irrigation. Irrigation equipment should include heads that deliver a pattern of water close to the ground. This makes the water less likely to be lost to wind and evaporation. Individual earth or decorative basins around trees and shrubs hold water until it seeps into the ground.
Shallow irrigation ditches next to rows of plants serve the same purpose.
This in turn reduces the moisture loss of nearby plants. Evergreens block unsatisfactory views and lessen winds. Large deciduous trees provide summer shade. Reduce grassy areas wherever possible. Grass is best separated from other plantings so that it can be watered separately.
