I have been working on, and modifying this water schedule over the last 15 years. Experimenting on my own yard and implementing these results on countless customers who's yards I service.

This is a base water schedule intended for well established turf-grass. Newly planted landscapes of less than one year will require more frequent watering. Watering interval will vary dependent upon micro-climates around the yard. Southern exposures, slopes, and berms may need water more frequent while northern exposures and shaded areas water less frequent. The water schedule is calculated using historical weather averages. Hotter or cooler than average weather conditions can impact the monthly water intervals. Sprinkler head type, nozzle size, spacing, and water pressure will affect the run time minutes.

A clear multi-program control timer will enable more scheduling flexibility. Drip irrigation may use a separate wider water interval than turf-grass. following this water schedule will promote a strong healthy landscape & save water on average by 20%-40% over short frequent watering.

Caution: Do not implement during the hot season.
December and January little to no water at all required.
