Mine hasn't really done much of anything since I've got it. The closed new leaf it came with has opened, but that's it. No sign of root growth. At least it doesn't seem to be declining, I guess.
Temps are almost 100F around here, but I seem to be suffering more than my orchids.
Try lightly misting the base of the plant everyday. I often notice on various orchids that it seems to encourage root growth, and coincidence or not, my Soph spouted 8-9 roots since getting it. It doesn't hurt to try at any rate!
