Time for a bigger mount?

[vlhart]

I got this Tolumnia back in November and it's been doing pretty well--despite the cat attacking it once. There's lots of new root growth. But I'm wondering if I should remount it since so many roots are trailing in the air. I water it pretty extensively since my apartment can be pretty dry and the roots that are in contact with the cork seem to do well throughout the day while it seems like the trailing roots are slowly drying up.

Is it time for a bigger mount?
