Peristeria Elata

[Danie]

I thought I had killed my Dove orchid after 5 years of trying.
It lost all these leaves so I put it in the barn to let it die. It was cold and very sunny in the barn and I didn't water it. When I looked at it a few month later it had grown a huge spike. I was so surprised and excited. Now buds are formed and I hope I won't kill it this time....I keep the soil moist and I hope I am doing the right thing.
Does any of you have suggestion about taking care of it?
Thank you. I would appreciate your help.
