I live in Mesa AZ in the high desert. My tenants refuse to water

[Lynn Harper]

How should I handle the fact that my trees, plants and grass are dying and I haven't been able to get my tenants to water them. One large tree is half dead and my tenant wants me to pay to have a cactus removed that she killed by not watering it. Landscaping is very expensive. It would cost $500 to take out that tree and another $500 to replant it. My contract says the tenant is responsible for maintaining the yards and she pays her own water. With 110 + temps in the summer everything dies if it doesn't get watered.

I agree with Doug. Also, you should consider desert-scaping the property to prevent future issues such as this. Rocks, cacti, mesquite etc last forever with barely any water. No water necessary with the rocks of course.
