|The home owner insisted they were "watering enough". Clearly|
they are not!
|There is an irrigation head in the middle of|
that green spot - which is in the middle of that
huge brown spot. Hmmmm...could this be
an irrigation problem?
|There is the head...way down in the turf.|
|Yes, it kinda sorta still works. Water comes out,|
but not nearly enough to reach adjacent heads.
|Conduct your own informal irrigation audit|
by placing containers in your lawn (on the
brown and green spots); collect water for an
entire run time and compare depths.
Your job is then to figure out WHY the coverage is lacking on the stressed areas (station run time, sprinkler spacing, pressure, heads that are broken or plugged or obstructed or too deep, etc.) and remedy the problem. If you can’t figure it out or don’t have the expertise, hire someone who understands irrigation systems to help you. Once fixed, the grass can recover remarkably quickly – but that will depend on how long you have waited to do something about it.
Turf can recover relatively quickly after the irrigation problem is resolved. This photo taken 2 weeks later (23 June 2016)
Looks even better after another week of recovery! (29 June 2016)
If you are living in a county that offers the CSU Lawncheck service and would like an on-site consultation (we diagnose the problem, but don't repair irrigation systems!), go here: http://www.extension.colostate.edu/lawncheck/book.shtml
There is a fee for this service in those participating counties.
Also, many water suppliers offer irrigation audits (generally free of charge) to homeowners and HOAs. Check with your water supplier to see if it is offered and you qualify.
