I wish I had that problem. They can get big and beautiful so why do you want to keep it in check? Can you move it to a bigger pot?
It's in a huge pot right now, like the ones you find in a mall or movie theater lobby. There are no bigger pots. I have to move it from my old place to my current apartment and I have no idea how I'm going to drag it up the stairs. Plus it's outgrowing the huge pot so now it looks like 6 plants in one. Since there are several plants competing for water and space, some of them are turning yellowish.
