How often should I water my lawn and for how long? The best watering times and length of watering depends on the weather, the type of grass, and soil conditions. It is generally preferable to water infrequently for a longer period of time than frequently for short periods. Watering infrequently provides deep water sources that roots search for. Frequent watering promotes surface root growth. On established lawns in this area, generally one inch of water per week is fine.
What time of day should I water? Watering early in the morning is the best time, followed by watering in the evening. Water in the middle of the day only if it is cool or if you have a new lawn requiring constant moisture. You should only water more than once per day if evaporation is extreme or if your soil wont hold the water because of the clay content or the slope of a hill causes too much runoff.
What should I do when it rains? Most timers have a button for shutting down for rain. This will shut off the system for one cycle, and it will operate automatically the next time for which it is programmed.
What should I do to shut down my system in the winter? Turn off main valve to system. Drain the mainline with manual drains, if any. Blow out the individual zone lines. Unplug the timer.
What should I do to restart my program in the spring? Plug in the timer and program the clock. Close all manual drains and open main valve. Turn off master valve and test each circuit.
Maintenance. On a monthly basis, adjust timer settings and check and adjust sprinkler sprays. On a yearly basis, clean filters in all sprinkler heads; manually operate each valve and check the wire and wirenuts in valve boxes for any damage. On as needed basis, unclog sprinkler heads and adjust installation levels of heads and valve boxes to ground level. Sprinkler heads may need to be adjusted to correct spray patterns that have gone out of adjustment.
Setting clock. Refer to your manual for adjusting the watering periods. There is also a brief synopsis of the procedure on the inside of the cover of your timeclock.
A healthy, well-maintained lawn will resist weeds and insects far more than a dry, poorly nourished yard. Along with your sprinkler system, we recommend our 4-step Pro Lawn program for a balanced, economical lawn care program for the long-term health of your lawn.
