I have had a supermarket phal for over a year. It is doing well, and even recently grew a beautiful new leaf.
It is currently in the original pot: a plastic pot inside a ceramic pot (as you see in countless supermarkets and big box stores.) The pot is about 6" tall. Although there are no signs, I fear the plastic could encourage rot.
I really like the Medusa-y, grey-green roots, and would love to put it in a ceramic pot with lots of holes and openings.
However, I realize this is simply a cosmetic / décor issue.
So my question is: Do I repot, or let it be since it's thriving?
