Why Has My Phormium Lost Its Colour?

My phormium has lived happily in a ceramic container for years but over time has lost its lovely pinky-orangey leaves and is now mostly greenish. Should I be feeding it? I thought the initial instructions said not necessary but may have remembered wrongly. I have very acid soil, and think I would have planted it in something like John Innes No. 3 and have topped up occasionally with a good compost. Something I am doing is obviously wrong. Sorry, no photo as my digital skills not up to uploading from camera to this page.

It is not unusual for the plant to revert back to its parentage foliage. If this happens, cut the affected leaves back to the base of the plant.
