northwest winter care for dendrobiums?

[melaniewicklund]

So I probably have made a grave mistake, but I cut the main cane down to the root base…. A few months ago the leaves turned yellow and I just left them. Unfortunately my mother in law came along and pulled all the yellow leaves off with only the lonely cane remaining. I was not happy with her but kept on nursing the plant with weekly watering and bright light. Eventually new shoots grew off the main cane that looked like mini canes. Now its pretty much winter in the northwest with minimal sunlight through out the day and cooler temps. I keep the plant indoors and in as much possible sunlight and reduced watering to maybe once every other week and yet to fertilize. The plant turned limpy and a light green yellow all over. I decided that the cane is not revivable so I cute it all the way to the base today but feel I might of just ended its chance at ever coming back. What should I do? Should I keep watering as normal and keep in sunlight or maybe let dry out for the winter and store in a closet to bring out during spring and summer? Im clueless.
