This orchid bloomed then was exposed to too much sunlight. I've treated it nicely for 3 years trying to get it to recover. I see new roots but no new leaves.

Hello Zeba

Can you tell us the name of your Orchid, do you still have pictures from the blooms?
In any case -
First, looking at the dark bark in a large pot, I see a pot with a built-in saucer, which could translate to sitting a long time with wet feet.
If my plant would sit that long without saying peep, I would take it out of the pot and inspect the roots. See if there are any in the bark?
You don't give your location, do you keep your Orchids in the house or do they go outside? I think this one one could use a Summer vacation outside in a spot protected from hot noon time sun in a tighter fitting pot with good drainage.

I don't recall the blooms b/c it's been some years now. I live in Texas with triple digit temps so I don't think it will survive that and being outside has it looking like it does now. There were lots of roots hanging out of the holes in the smaller pot so I gave it more space. Are you saying there could be a problem with the roots though there are roots growing outside the pot after the replant? I'll check them to see what's going on.

No, most Orchids which we are growing are epiphytes and a healthy Orchid will usually push roots away from the pot and appear on the outside. Nothing wrong with that.

Orchids are generally agonizingly slow growers, especially if they've suffered a setback. Don't despair, the fact that it's growing roots is encouraging.

Have you fertilized it with anything? They like a consistent feed of very dilute soluble fert, preferably sprayed on the leaves as well as enough to get into the medium to reach the roots. Remember they're epiphytes, so they feed through their leaves as much, if not more than through the roots. The roots function to attach to wherever they're growing in many species. In nature, the leaves collect nutrients that fall on the plant from trees, and the rain.

Try keeping a spray bottle with 1/4 strength soluble orchid fert in it, and spritz the plant a couple of times a week to encourage growth, and keep it more humid around it, as well. If indoors, and your windows are tinted like mine are, it's also possible it's not getting enough light to bloom. Move it gradually closer to a window or under a skylight, east facing would be ideal. No direct sun unless it's winter, more gentle.

Thank you. I'll keep caring for it to see what happens.
