I have 4 zones, and I want to set up a watering schedule that works and doesn't kill anything off. I have already set up a smart schedule to water, but my concern is that the watering schedule that has been configured automatically based on the settings provided, is using way too much water. I have small sections of grass and shrubs, and it wants to water the grass for 26 min and my shrubs for 46.. I do not have any sensors either.
That seems awfully long to me. I live in the northwest and have sandy loam soil. I have had two different gardeners tell me that the shrubs should be watered daily for about 8 minutes and the grass for about 12 minutes. I was wondering what your thoughts were on this and if I should use a daily schedule instead of the smart flex schedule im using.
Oh another thing, I am running these rainbird 32SA heads and they put out a ton of water! which is another concern of mine
