Does anyone charge for watering? I'm losing lots of business because of this drought and most of my customers don't take the time to water their lawns. They are turning yellow. Do any of u offer watering services? Especially to the elderly who don't think they can even do that? How much sprinkling do u think it would take to help the grass grow? Like an hour of sprinkling? Just wondering if this could be a way to make some money during down time as well as get the grass in shape again to mow?
