Good God, Murray! That plant could devour New York City! No, I can't imagine a pot that could contain it...

Jen, if your plant isn't getting enough water (the p-bulbs are telling you that), it won't bloom. Consider a potting mixture that will provide more moisture, or simply water more. If it's that dry where you are, you won't rot it the roots if the mixture allows good air access. Is S/H an option? I don't use it, but it does provide water as the plant needs it. Maybe it wouldn't work in an arid environment. My Onc Alliance guys go nuts in sphag, but I'm in New England. And with the hot weather we've been having, I'm watering constantly (they're all in clay pots), and it's making me a bit crazy.

Just some thoughts.
