These guidelines are for established plants (1 year for shrubs, 3 years for trees).
Additional water is needed for new plantings or unusually hot or dry weather.
Less water is needed during cool or rainy weather. Drip run times are typically 2 hours or more for each watering.
The costs of water maintenance, plant loss and replacement, and decreased property values are all
financial impacts on homeowners. Recent local studies show that many landscapes are over-watered
as much as 400 percent.
Over watering encourages excessive growth diseases and other maintenance problems.
Deep infrequent watering encourages strong healthy root systems that can better tolerate intense heat and
periods of drought.
Effective irrigation system design, installation and maintenance are important.
Sprinklers should serve only the required turf areas and not spray on buildings, fences or non-landscaped areas.
Excess water on sidewalks, pavement and block walls causes damage, increases liability and wastes water.
Watering should be done before sunrise to reduce evaporation losses.
Turf areas, planters, trees and shrubs should be watered separately to meet varying water needs.
Always irrigate the entire depth and width of the root zone regardless of the time of year.
Automatic times and moisture sensors make it easier to manage irrigations.
Once or twice a year, water twice as long to leach out salts and buildup in our soils.
