I'm new to the in ground sprinkler system game. It's set now to go off every day around 3:00 am.

I don't want to overdo it. I set the seasonal adjust to 40% but not sure if I should just leave it on all winter or shut it down at a certain point.

Maybe some of you guys could ask your gardeners what they advise?

I wouldnt water the lawn daily this time of year. Keep the flower beds watered but shut the regular lawn zones off. Also, drain it before a hard freeze, I busted my main backflow thing couple years ago after a freeze.

That's what I was leaning towards. Do you keep the flower beds going until a hard freeze?

You're supposed to drain your lines during the winter particularly due to a hard freeze.

Assuming your have St. Augustine, root rot could become a problem b/c the heat of the sun is minimized during the winter to dry it up.

Pretty much yea, unless she pulls up all the flowers then I don't water anything during the winter months.

My flower beds are all small bushes for now. I guess I'll shut her down this afternoon.

I've never had sprinklers before, but do now. How the hell do I drain them for a hard freeze?

Are your solenoids above ground or under with a cover?

Mine are above ground so I turn my sprinkler system's water supply off at the flow-back valve for the winter.

Do you notice or see something in your yard with PVC pipes running to and from? All of the solenoids I have seen are green but they could be black. Mine are Orbit and look like this. You will have one of these for each zone. How many zones do you have?

Mine must be underground. Nothing like that. 6 zones. I can shut it off at the meter, it's separate.

I go to Louisiana for Thanksgiving week so that is when I turn mine off for the season. I had to come home early one year when I didn't shut it off and the temperature was supposed to be in the mid 20's.

I would just keep an eye on the weather and turn it off if the weather is to be below 30 degrees for longer than a few hours. If you travel I would definitely turn it off before leaving. Turn it off at the controller box also.

I'm still watering 3 days a week. 10 minutes per zone. October is our driest month. I water until 1st freeze then shut it off for the winter. My stuff is underground. I don't drain anything.

What is your summer program? I don't think I have a rain detector so I guess I need to stop in manually if it's a rainy month.

Once the grass stops growing much, usually around mid to late Sept here, I shut it off. It has not rained here, but the grass is pretty dormant and fine. The lawn service wants us to shut it off even sooner.

Watering in the fall causes brown patch fungus, those huge patches of discolored grass that will eventually become bare spots.

I see many neighbors who are still watering every day. Wasted money. One has brown patch every place the water hits heavily. Can't take a clue I guess.

I shut mine off at a valve near the meter. Then I open a couple of screws/valves on the backflow preventer, which lets out the pressure in the line. That's it for winter.

Your irrigation system for your grass zones should be no more than 3 days a week in summer. You can manually add a day or two as needed in drought conditions. If you water turf less frequently but with a longer run time the grass roots deeper and is healthier
