Sorry Mike, I've had a chaotic few days and didn't get back here. I think cactus soil would be good, it's really a desert plant. I have such high humidity and so much rain half the year that I try and make anything I put in a pot have super good drainage. It has worked well for the pygmy date palm. I do worry, now that you caused me to really look at it, that it isn't getting enough sun. It looks kind of cool in that it is leaning waaaay out over the pool looking for the sun but it can't be healthy for it. I don't really have anywhere else to put it though so hopefully it will adjust.
