One of the most common issues with lawns is irrigating too much. It is obvious when rainfall occurs that the sprinkler system should be off. Even before this week of rainfall, homeowners were watering too much. The result during this time of year is stressed turf that easily is taken over by root diseases. These diseases are difficult to manage even by lawn care professionals. The recovery process can take a while since grass has to regrow into areas or larger zones have to be resodded.
The take home point is to turn off sprinkler systems and only turn them on when the grass shows signs of wilt.
