Which orchids in YOUR collection get a winter rest?

[justino222]

So i just moved my orchids indoors due to it getting and here in PA it snows and im sure in their natural locations, they never Go through snow lol.

I have quite a few phals and 2 oncidiums (think thats how its spelled) but someone here told me they look like dendrobiums?

Do they need a winter rest? If so how would i do it

Some of the orchids look weak from lack of care. I got most of them from my aunt who lost interest in them and let them go.
