Do you have an underground irrigation system?  If so, how often do you monitor it to make sure that it’s functioning properly?  You should do this at least monthly when your lawn and plants are actively growing.  Not only should you see that the sprinkler heads are rising and turning properly, (and providing the proper coverage), but also you should check the filters.  These are located in the top of each sprinkler head.  They should be inspected and cleaned as needed.  Also check your controller to see that it’s set with the proper operating times, (15-20 min. for spray heads, and 35-45 min. for rotary heads); and the days of operation.  Currently we are only allowed to water 2 days per week, (Wed & Sat for odd numbered homes, and Thurs & Sun for even numbered homes).  And remember, irrigation systems are for providing supplementary water when rainfall is inadequate.  Do your part – help conserve water.
