Group plants according to their water needs

Efficient irrigation begins with the planting arrangement.
Regular spray-irrigation systems deliver the same amount of water to an entire group of plants, regardless of how much water each plant needs. Usually, these systems are set up to satisfy the thirstiest plants. This over waters the rest.  Planting in hydrozones, or groups of plants with similar watering needs, promotes efficient irrigation design.
