Dryadella Zebrina help, please

[orchidegg]

Hi,
I grow one in my East facing kitchen window in sphag in a little clay pot. I suspect maybe more light would help. Mine gets a lot of light and even direct sun in the summer and is in bud now. I generally don't see much change in the way of foliage, a new leaf here and there and an old one falls off. Yours looks pretty healthy.
I wouldn't worry about the roots too much if you want to take it out of the pot and check as long as it's been well watered they are pretty flexible.
Hope that helps!
