This schedule is based on local (City of San Luis Obispo)
conditions. Unusually moist or dry conditions may require that
irrigation differ from this schedule. Two to three inches of surface
mulch is recommended in drip irrigated areas. If you use surface
mulch, your schedule may be cut in half. Surface mulch is not
recommended in sprinkler irrigated areas as the mulch will intercept
sprinkler irrigation; keeping it from the soil.
System should be turned off during the rainy/cool season. Most
automatic sprinklers have an “off” or “rain/off” switch, which will
de-activate the controller without loosing its programming.
These months (including September) are transitional months that
normally have cooler evenings. Irrigation should be reduced from
summer irrigation schedules.
The irrigation
schedule durations are for the total minutes to irrigate per week,
based on the average irrigation system – During warmer weather, this
weekly total may be divided up into three or four watering days. The
more accurate alternative is the inches of application per week –
You can accurately adjust your schedule by measuring the inches of
water applied per minute and then running the system only long
enough to achieve the desired weekly application.
Fixed spray
sprinklers are sprinklers that do not rotate. Rotating sprinklers
may have a wide difference in
application rates due to design. Please check with manufacturer
specifications to determine the application rate.
