TURN IRRIGATION OFF this week, and next week until rains stop.

ETo for this time of year is running about normal at 1.2" over 7 days, which is corresponding to 3/4" water required for High quality turf ( sports fields ) or 1/2" of water required for residential lawns.  With the 6" of rain we received, I would say it is a safe bet to TURN IRRIGATION OFF.  Leave it off least until next week, see if we get more rain mid week.

Realistically, the biggest risk to plants right now with all the heacy clay in the area is root rot and plants drowning, not getting enough time between rains to allow the roots to dry-out and bring oxygen into the root zone.

I have seen more MOSS in Austin this year than in any of the past 20 years indicating the ground is highly saturated and runoff is apparent in even these brief 1/2" rains.

We really need 5 to 7 DRY days with no rain before we need to turn the irrigation back ON. 

HAPPY MOWING ( between the rain storms )
