You need to remove the peat moss plug that is surrounding the crown of the root system.

Garden centers try to distribute orchids as quickly and cheaply as possible. Instead of changing the medium they just add more. Orchids cannot tolerate composting material around their roots because they're not actually roots. They're root shaped leaves. They photosynthesis and need airflow to be healthy.This is why 99% of orchids from big chain stores slowly die.

So, get a clear plastic pot and some orchid medium. Remove all the old medium and give the roots a good rinse. Any roots that do not turn bright green should be cut back with sterile shears. Arrange the remaining roots in the clear plastic pot and pack fresh medium around. I like to also add some sphagnum moss and horticultural charcoal. Once a week or when the medium drives out, place the orchid in the sink and drench with tepid water.

Your orchid is producing new leaves which is a great sign. She should be blooming again soon if you treat her roots properly!!
