V. Udom Gold x V. PranermPrai x Ascda. Suksamran Spot Care

[BANeils]

I have had this orchid for about three years, and the poor thing has been struggling because I don't know the correct care for it. It is in a small plastic basket with no growing medium and the roots are just hanging out. The leaves are not a healthy green anymore and have the hint of brownish spots all over them. I have moved it into my master bath which gives it indirect bright light from a south facing window. What if anything more can I do? Or is a decent burial all I can hope for this once gorgeous plant? The flowers were a red-orange color with spots on it as far as I can remember. Please help me on this I would love to see those flowers again.
