Phaelenopsis 1.5 years, no luck with new stem. New leaves, new roots, what do?

I have a few questions. How well drained is the pot? What is the humidity level where the plant grows? How broken down is the bark?

I doubt you need to repot. It appears that you have a plastic pot sitting in a decorative pot, so drainage should be OK if you remove the plastic pot when watering. The plant appears dry, and the roots show classic signs of low humidity.

Finally, often growers push plants to bloom, causing them to bloom at a time not necessarily natural for them. It can take these plants 18-24 months to rebloom. Overall your plant looks to be in fairly good health so I think you just need to tweak the care a bit.
