Properly designed irrigation systems allow plants to thrive, reduce maintenance requirements and conserve water. Efficient irrigation systems water plants at their root zones and minimize overspray in lawns.

The first step to having an efficient irrigation system is having an efficient landscape design.

For lawns:

  • Spray nozzles should be arranged to provide head-to head coverage
  • Avoid overspray onto sidewalks, driveways, fences or planters
  • Use the same type of spray head on each zone for uniformity

Head-to-Head Coverage: The pattern spray of one sprinkler hits all the sprinkler heads next to it.

Timers: Irrigation timers are convenient for automating the irrigation process. Adjust the timer for seasonal changes or weather conditions.

Hydrozones: Group plants with similar water needs on the same irrigation zone to avoid over or under watering plants. Ideally, trees should be on a different zone than shrubs since they require deeper, less frequent watering.

Drip: In most cases, drip irrigation is best for watering trees and shrubs because drip emitters can easily be situated around each plant. Converting existing spray irrigation to drip is easier than one may think.

Trees: Drip tubing with in-line emitters is ideal for trees. Create concentric rings around the tree to encourage even root growth. Add additional rings as the tree grows and the root zone expands.

Consider hiring a qualified professional or consult a local irrigation supply company if installing a new system.
