Pitaya Plans

I am bored and sleepy. This has caused the wheels of my mind to start churning. It would be wonderful if I could grow pitaya plants to the point of fruiting and then sell them at the local flea market. I don't know if there is a market for them, but there is definitely a shortage: I have never seen them in this area, and a search for them at the end of summer proved fruitless, literally. I have thought the same thing about my banana plants. Sell all the many pups. Anyway, if I trim the tips of the pitaya plant so that the plant grows more or less within the circumference of the container. I saw a picture of a pitaya that looked like a weeping willow with an extremely good hair cut. All the weeping branches were trimmed away from the ground at the same height. I would like to replicate this look at some point.
