No signs of new growth for 1 year now.

[CNR]

Can anyone offer reasons as to why an orchid plant (Phal) wont show signs of new growth? I rescued this dying plant over a year ago. I’ve managed to save approximately four other like-kind orchids who are all doing very well now. Apart from the roots – which are plentiful and vibrant green – there is no sign of progress over the last 9-12 months. It sits approximately four feet away from a south facing window with defused light, and gets watered only when the growing medium nearly dries out. Any help would be much appreciated. -Thank you
