I lived in Las Vegas for 5 months last year and grew bananas the whole time. I planted them in a spot where they didn't get direct sunlight during the hottest part of the year. They did OKAY, not great. I think the soil they were in could have been A LOT better.
I'm thinking about what i'm going to do when I get down there again in a month. I'm thinking a raised bed using railroad ties and filling it with a lightweight, well-draining compost/peat/perlite mix. And most likely adding a shade cloth mounted on a wood frame.
Either that or just build a greenhouse
