Den. Micro Chip, pseudobulb and leaf browning, dying

[vlhart]

Been awhile since I've been on the forum, but I need help with this 8 year old Micro Chip that has been healthy and bloomed each year despite several moves and some neglect. About a month ago the pseudobulbs began to brown and the brown grew up the stems and into the leaves, starting with the oldest canes. It had been kept pretty dry (NY winter), watering once a week. I think I may have soaked the roots once for a half hour before this started.

I isolated it, watered it a bit more regularly, but the pseudobulbs didn't take up the water and its only gotten worse. There was a slight spider mite situation but that doesn't seem to be the root of the problem.

Can it be saved? Any advice would be greatly appreciated, as this was one of my favorites. TIA!
