Some local iirigation companies began winterizing (turning off) sprinkler systems about ten days ago, and most all companies have systems shut down by mid October . We are currently in drought conditions here. Then there's October when we often experience low rainfall, sunny weather with low humidity and drying winds......causing lawns to dry out/burn out. Often, we see 80 degrees in late October. Grubworms are really bad here too, and we expect grubworm activity to persist through early November.....compounding the problem. One local sprinkler company charges extra if they delay winterization. Why? Root development ocurrs most in fall, but with dry soil --- that ain't gunna happen. Mowing of turf usually continues through late November here -- sometimes thru early December, so why would irrigation companies shut down irrigation systems months before ???
