Grass, plants, trees and shrubs are all healthier when watered deeply and infrequently. Each month throughout the year, water the recommended times per week for best results.

  • 1x a week:  February, March and November
  • 2x a week: April, May, September and October
  • 3x a week: June, July and August

No irrigation is needed in December or January. Hand water as needed.

Sprinkler Irrigation

The cycle and soak method of sprinkler watering on lawns allows water to soak deep into the soil creating healthy roots and eliminating runoff.

  • Run 3 cycles per watering day
  • 1 hour between each cycle
  • 4 minutes for a fixed spray or 8 minutes for a rotating spray
  • Monitor and adjust as needed

Drip Irrigation

Drip low and slow to allow plants, trees and shrubs to be watering directly at the root systems using a low pressure for a longer period of time.

Low-flow emitters deliver bead-like droplets (1-4 gallons per hour)

High-flow emitters deliver a steady, light stream of water (up to 20 gallons per hour)

Water based on your drip emitter’s rate of flow:

  • High flow (up to 20 gallons per hour): 12 minutes
  • Low flow (up to 4 gallons per hour): 30 minutes
  • Low flow (up to 2 gallons per hour): 60 minutes
  • Low flow (up to 1 gallon per hour): 90 minutes

Because every landscape and irrigation system is different, you may need to adjust this schedule. Variables such as soil, weather, flow rate, and plant type will affect irrigation needs. If a plan appears stressed, check around the root zone to determine if the soil is dry or waterlogged – both conditions can cause plants to exhibit a wilted appearance.
