It could be too much water. I'd think twice a day might be too frequently to spritz them. Depending upon how humid it is, perhaps once daily, or once ever few days. If it's really arid, dry, perhaps daily, but if your humidity is high, it shouldn't need frequent spraying. It's difficult to tell from the photo, but too low light might also be part of the issue. You are treading where I haven't attempted going in over thirty years. My climate does not require bringing roses inside out of the elements. I tried growing minis under lights eons ago and found it was not something I cared to fight. They are significantly easier and happier outside here, so I keep them there. I understand your climate isn't as forgiving this time of year. But, honestly, you are attempting something I haven't. The best I can do is suggest what the symptoms appear to me. I'd think, as you suggested, too much water and perhaps insufficient light. But, I could be wrong. Hopefully others who have brought them inside over winter and experienced what you're observing will come up with more suggestions. Kim

Are you in a cold climate and your trying to overwinter these roses?
Just trying to understand why there in the garage?

Jim, I live in cental pa. It is about 40 degrees now.

Kim thanks for the advise. Sounds good. I will cut back on water. The garage is 70 degrees and alittle cold air comes in the door.

Oh I forgot your close to me Suzy11..sorry

I have overwintered outside successfully but never had any luck with roses indoors.
Best of luck...
