I'm not really sure what any of that means...its actually about 7 years old...and yest, its never gotten bigger than that. I repotted it in the same plant. I think it was over watered for a few weeks. I normally travel 45 weeks a year. My wife was watering it and while I was home for a few weeks, I too was watering it. I think that happened. Now it just has the bigger roots and all the tiny roots are gone. I moved it outside to repot it as there is more light and its about 72 today. I'll move it back and start misting the leaves this week. Hopefully it comes back. I love the flowers it produces.
Any need for food or fertilizer?
