Any signs of fungus yet?

Maybe somewhere else in the country. But, here the roots can't even penetrate the hard-packed sand.

Nope

And make sure you keep frequent check of your Seasonal Adjustment. It can change daily (after midnight). Many people think they're watering at 100%, only to learn it can possibly drop to 40 or 50%. To avoid the Seasonal Adjustment ever changing from what you want it to be set at, take the panel off, and disconnect the blue wire.

I turn my system off during the summer months and rely on the rain. My lawn is always green and I save a lot of money. On rare occasions I might have to turn it on manually if it hasn`t rained for a week or more. If I go away for any lenght of time, I`ll put it back on auto.

Up until a couple of days ago, what rain? Also, what type of magic grass do you have that stays green despite the heat and lack of rain?

Send pics !

yes pics

hard to believe without sprinklers

I had one sprinkler head clog up, that area was brown quick

I have St. Augustine grass, I`ll post a pic

This is it, I`ve watered once in the last monthAttachment 61434

No one setting is good for everyone. My own experience has revealed that about 30 minutes per section seems reasonable about two times per week (less or even none at all during the rainy season)

Home Depot and Lowes do not sell Hunter heads, but ACE Hardware does.

Just asking, why wouldn't you have your landscape co. come back and do it right?

Better Way to Set times
 

One reponse was correct, it depends on the head types. It also depends on what soil is under the sod; each lot is a bit different. I went to clemson Univ's ag site and read zoysia grass here needs 1 and 1/2 inches of water a week. Take the time to set out a plastic container and run your sprinklers to see how much depth you get in the time you run. Then buy a $4 rain gauge and check what Mother nature gives us, and add more if needed. Since I did this I have cut my irrigation water tremendously. It's definitely worth the time.

agree that is the best way
