I thought that the sphag in bag method was in order to encourage root
growth? Does it also encourage new leaf growth? This seedling has quite a
lot of healthy roots, just the leaf situation is dire.

Hi Joanna!

The plant will get new leaves as well. My Phal seedling lost one leaf before I put it in the bag (there were still two left), but now it has grown a new leaf the last month. I think I have had it in the bag for 3 and a half months now.
I think it is hard work for a little plant with only one leaf to encourage root growth. When you put it in a bag with sphag, it might not be so stressed if you see what I mean. Are you sure the roots are healthy? Are there any green roottips on your Phal, what medium do you keep it in, for how long have you had this seedling?
Good luck!
