I bought this orchid about a year ago and it had beautiful blooms and seemed quite happy for a while. After the blooms finished, the spike dried out and I cut it down to the base. Since then, it hasn't produced any spikes. It has grown a few more leaves and increased in size, but now that I've read a few posts on this forum I'm quite certain the roots are unhealthy. I've posted a picture below. I want to re-pot it and do things right to make the plant healthy again, but I'm not quite sure where to start. Do I need to trim back the roots? Advice for re-potting and general maintenance would be appreciated! Thanks!
