Re-potting

[mmorehead]

I am going to re-pot my phals tomorrow when I get home, and was wondering if you wouldn't mind answering one more question for me. They are currently in 6" pots (not 8" as previously posted), but the roots are growing out and over the sides. Should I get bigger pots to put them in, or should I stay with the same ones. If larger ones are needed, what would you recommend? I've read that the roots like to be snug, and that larger pots are not a good idea.

Again, I greatly appreciate your help. I'm so grateful to have found this site!
