Are the stems still green and have some dormant "buds" on it? If so, then your
rose is all right. My indoor
rose dropped all its leaves in autumn. I stared at a bunch of green stems for a couple of months. Then in
spring, it put out new leaves from the dormant buds and soon filled out into a beautiful, healthy
plant. It's part of the growth cycle...
If it has no leaves and the stems are brown, then it's probably dead. You should consider the following:
overwatering, underwatering, diseases, wrong amount of light,etc. Many causes lead to
plant deaths.
