• Water only when required. Only judge water requirements in the

• Water deeply to promote deep roots and healthy turf. An inch of
water will generally penetrate the soil to a depth of six inches.
• Water slowly for better absorption. Use drip or soaker hoses
wherever possible.
• Never water on windy days.
• Water early in the morning to reduce wasteful evaporation.
• Mulch flower, groundcover, garden and shrub areas two to three
times a year.
• Water newly planted flowers, shrubs and trees individually.
• Water without creating runoff.
• Audit irrigation system 1 or 2 times a year.
