    How often do these sprinkler systems come on? And about how much water output?

    I understand the morning is probably the best time-around 4am. As I understand one inch per week is good; and to do it only once a week to prevent shallow root growth-water junky grass etc.

    But it is hot as a mofo and grass seems to be patchy and fried in areas What should I do? Spotseed, some hay on it perhaps? And as I mentioned earlier what are those irrigation systems like that make that stuff on-do they come on every morning and do they aerate twice a year or something?

    As often as it is scheduled.

    Do an audit and find out.

    1" per week is a grossly over-generalized application rate.

    Audit the irrigation and soils, fix the problems.

    Call a local commercial irrigation company that deals with large systems on a daily basis. This is obviously not your expertise. Hand it off to a company that knows.

    About the only thing correct about the 1" per week.

    Blunt but soo true....

    You also have to look at how wind, sun, cars parking over spray heads, carts? elevated mound exct......so many things can be causing this.

    Off subject but another only at Wal Mart story:

    Our Local wal-mart has an area that is ivy and a v-ditch that goes in the middle. Well this homeless guy was sleeping in it. From the parking lot, you can't see it because of the height of ivy.

    Well the local landscape company fixed all the broken heads this past weekend.

    Our local paper gets a phone call from a homeless guy that wal-mart is trying to make it impossible for the homeless people to get sleep because the sprinklers come on in the middle of the night and gets them and their possessions wet.

    Go figure......

    Call an irrigation company to have them do an audit on the system--
    ...Audit to determine problems, broken heads etc.and DU on system to see if you have proper coverage--it sounds like you could have a poorly designed system (or lots of broken heads) meaning-when the irrigation comes on, it waters more in some areas, less in others--you want to fix this --you want every area on a particular zone to receive approx. the same amount of water/..

    All systems require regular checks to find and fix problems/failed heads etc...a system which has not been regularly maintained will likely have lots of problems causing the grass and plants to suffer/wasted water etc.-

    It amazes me the number of large properties which DONT require regular irrigation checks and repair and then complain about plant material not looking good-:dizzy:
