I got a rooted cleistocactus cutting a few months ago. I've never rooted a cactus nor planted a rooted cactus cutting, so I was pretty much winging it when I potted it up. I was afraid to plant it very deep for fear it might rot if too much of it was in the potting soil.

It's growing like gangbusters, but it's kinda crazy looking. Is there something I can do to get it to grow stems on all sides of the "trunk"? The "trunk" is the part of the original plant that was rooted. I wish I had taken a photo when I first got it, but here it is on 6/30/16, about a month after I got it (please excuse the dirty window):

And a couple different angles:

Any suggestions? I've been wondering if I should put it in a little bigger pot to give it more space to stretch out. Thanks,
