I've had him a couple of weeks. I haven't pulled him out to look at roots or try and repot--I don't want to touch too much until I know exactly what to do with him.
He appears to be on just plain coarse bark. Due to the level of neglect I'm assuming no fertilizers, and obviously hasn't had enough water.
I've watered him twice, let him completely dry out in between. Watered by letting the bark soak through for a minute and drain completely before placing back under light.
He's got some new root growth since I got him, which is nice. He also appears to have a new little leaf or pseudobulb (I can't tell) that I just noticed today. It looks healthy and happy, whatever it is.
Can I get some general tips and next steps, please?
