Healthy soil and sustainable growing

["elderberryjam" <elderberryjam@zippytech.com>]

My ex husband and his wife are visiting us (in Ohio), from Phoenix for our 
son's HS graduation. She likes to garden, but hasn't tried much in their 
sandy, cactus-y lot. I served kolarabi along with many other cut vegetables 
I bought. She had never had it before and loves it. I have visited the 
southwest, and have seen my cousin growing nice tomatoes in her flower beds 
near Sedona, and an acquaintance in Holbrook growing beautiful lettuce under 
a cloth.

Is it possible to grow kolarabi fairly easily in Phoenix? If so, are there 
any special tips? I Googled it, and came up with the growing season being 
fall and winter. Things there are quite a bit different than in Ohio. Can 
you use dishwater for your garden? Thanks.
