Please see additional scheduling tips below. Plant Types Turfgrass: Cool season turfgrasses such as bluegrass and fescue. Warm season turfgrasses such as St. Augustine, Bermuda, and kikuyu.Traditional Shrubs & Trees: This includes common garden plants like magnolias, palms, roses, calla lilies, philodendrons, and hibiscus.California Friendly Shrubs & Trees: This includes most CA Native plants and other common plants such as oaks, strawberry tree, agaves, sages, lavender, and succulents. Season Adjust %:Ā If your timer has a "seasonal adjust" or "budget" feature, then you may alternatively program your timer with the July/August schedule, and then use the Season Adjust % to easily adjust your watering to match the seasons. You do not need to add/remove water days!Days:Ā The number of days per week.Cycles:Ā The number of cycles or run times. For example: 3:00am, 4:00am, and 5:00am. Multiple cycles helps prevent runoff, and helps plants' roots grow deeper so your garden can grow better.Minutes:Ā The recommended number of minutes to water which varies with the type of sprinklers used and the weather. Spray-head Sprinklers - use the recommended number of minutes. Rotating Sprinklers - multiply the number of recommended minutes per cycle by 3. Example: 3 minutes x 3 = 9 minutes per cycle Drip - multiply the number of recommended minutes per cycle by 5. Example: 3 minutes x 5 = 15 minutes per cycle Be Mesa Water Wise How You Can Save Water Landscape and Gardening Suggested Efficient Irrigation Schedule Waterwise Plants Featured in the Mesa Water Garden Rebates and Incentives Water Conservation Requirements Water Smart Education and Outreach
