15 to 60 minutes on designated plant valves
1 hour to 5 hours on designated tree valves
15 to 60 minutes for plants and trees on same valve
Optimum soil moisture depths for small to medium shrubs is 12" TO 18"
Optimum soil moisture depths for large shrubs to trees are 18" to 36"
WATER FROM 9AM TO 4PM.
The amount of watering time depends on the type of soil in your landscape. Be sure to use proper cycle & soaking methods especially in areas with high runoff potential.
Watering less than 3 times per week during the first four weeks after installation can result in distress and drying out of root ball or root zone of your plant material. The amount of watering per day should rarely be adjusted as it is your goal to reach optimum soil moisture depths. Changes to your watering schedule after the initial installation period should reflect the current season, temperatures, and the type of plant material in your landscape.
If outside temperatures are above 95 degrees, schedule your drip system as late in the morning as possible for maximum soil moisture in the hot afternoon hours. Take a look at the Southern Nevada Water Authority website for further details that may affect your watering schedule.
Proper Cycle & Soaking Methods
" If your landscape area has steep slopes or heavy clay soils, it is especially important to implement proper cycle & soaking schedules. To find the proper schedule, simply divide your total watering time into 2 to 4 start times. Start times should be scheduled within 1 ½ to 2 hours of each other. This pushes the previous watering deeper to achieve your optimum soil moisture depth.
