Xeriscape zone watering more often than Tree


#1

That’s basically it. I have two zones, one xeriscape and one which needs more water than that. I selected Tree as the latter type but backed off the watering duration to 14 minutes. I use “weather intelligence” and would like to “set it and forget it” throughout the year. The dry watering schedule is very erratic and doesn’t seem based on the weather at all, often twice a week or more (this is in a cool San Francisco climate). It also waters all the time right after a rain. Meanwhile the wet zone waters quite infrequently, maybe once every two weeks. Why is this and what can I do to change it? I might as well just schedule the irrigation manually if this so called weather intelligence is so unintelligent. I expected better…please help. Thanks.
