Tips for Responsible Irrigation

  • Design and maintain a yard that thrives predominantly on rainfall once plants are established.
  • Most established trees and shrubs need watering only during times of drought.
  • Water your lawn and other plants only when they show signs of stress.
  • Comply with the Town of Hilton Head Island’s irrigation ordinance.
  • Calibrate your sprinklers to apply 1/2 to 3/4 inch of water per application.
  • Mow lawns high to encourage a deeper, more drought and pest tolerant root system. The higher cut also shades out weeds. Cut no more than 1/3 the height of grass blades with each mowing.
  • Put a rain gauge in your yard to track rainfall to avoid unnecessary watering.
  • Connect an automatic rain shut-off device to your sprinkler system’s timer. Set the device to 1/2 inch so it will override your system’s timer when enough rain has fallen. Replace back-up batteries in your system’s timer each year before the rainy season. Check to see if the shut-off device is working properly.
  • Design or modify your sprinkler system to water lawn areas separately from plant beds requiring less water.
  • Comply with the Town of Hilton Head Island’s irrigation ordinance.
  • Use a drip or micro-spray irrigation system to more efficiently water plant and flower beds.
