The answer to that question is no! Over watering can be very damaging to your grass, it will allow fungus and weeds to grow. We offer a rain sensor that communicates with your timer that if it has a rained a certain amount it will bypass your watering for that day so that you are not over watering your grass! This is a great thing to have installed and we recommend everyone having a rain sensor installed on their system!! Give us a call today at 256-851-2776 to get on the schedule to have yours installed!!
