My irrigation system is a little unusual in that it is almost all drip irrigation. Most of it is grass and front flowerbeds with mostly shrubs. I am not certain about our soil type other than the majority of it is clay. The system recommends 1 hour and 9 mins for several of my zones. In the past…

I have drip zones that are scheduled to run for 10 mins and I have drip zones that are scheduled for an hour, also at different frequencies. There is no one answer. It all depends on how much water your emitters are putting down and what types of plants you have.

Hi @pgarriso1 . I’m curious how you get runoff with drip? True drip is supposed to be slow enough that it will soak before run-off, and the longer you run the deeper the soak. Like @beranes so much will depend on your circumstances. Where do you live, what soil type do you have, how mature is yo…

At a certain point, the ground becomes saturated, and because of the slope, the water runs off. I read another comment where the emitters were putting out water faster than the clay soil could absorb it. I am going to lower the time to under an hour and use a manual cycle and soak. See if that gi…

It is mostly Saint Augustine grass and two mature oak trees.

@pgarriso1 I’m a bit confused. Is the runoff on the drip or grass, and what type of gallons-per-hour do you have on each, or is the grass not on drip?

There is a lot of confusing and contradictory information here. Let’s start from the top and just focus on those zones that have runoff. Are these zones: All sprinkler/all drip/mixed? lawn/trees/flowers/mixed? If mixed, what is mixed with what?

I am getting runoff from the grass zones that are on a Drip system. This was with my old control that would run after rains. So the ground would be pretty saturated already. Not certain the gallons-per-hour. My guess is .7 to .9. Not bad runoff but only was running 25 mins then. It would pool…

The zones are drip. Saint Augustine grass lawn with on mature oak tree… I notice it more when we have had rainfall and the ground is already fairly wet. I would run the zone for 25 mins and would get pooling and runoff (due to slight slope) on to the side walk.

Just to clarify: you water your lawn with a drip? Is it one of those subsurface systems?

Yes that is correct. It was put in during a drought. It is subsurface.
