In the Ash Fork area where we live we have to haul water or have it delivered which is a challenge in itself but when it comes to gardening are water usage doubles in the growing season or until monsoons arrive.
Starting plants from seeds seem to do well for us but keeping the plant alive through the hottest days of summer is another challenge.
Final challenge is the wild life and free ranging cows-cows are much easier to deal with we just have to keep our gate shut but the wild life so frustrating! Last year a gray squirrel kept digging in my raised beds and eating some of my vegetables.
