Customers not watering properly? Not paying attention to repeated verbal and written instructions? Say it ain't so!! They either don't water or they over water. Dry as a bone or mucky, pick one. I had one guy who would water for 2 hours, 3 times a day. Damping off fungus hit, and he expected me to spray it for free, and fix it for free. I had warned him what would happen, and how much Banol cost. Ended up in court. We won. You just can't fix stupid.
