Can you tell the difference between an irrigated lawn and a non irrigated lawn? We can’t stress enough how important water is for your grass! Having your lawn property treated is just a piece of the puzzle. Along with treatments, a lawn needs to be cut regularly. Most importantly, it needs to be fully irrigated for the best results. If you are not running your system regularly.. Or just not running it at all, it will result in thin, discolored, unhealthy grass.
