It did not bad the first year, even producing many blossoms, but now the plant is struggling. The plant is indoors (do to a very cold climate here). The original plant was growing in a semi desert area 500 miles south, and of course outdoors. On my plant, when the leaves come out they start to curl and then the area that started to curl dries out. As the leaves wilt I prune them off and there seems to be many more buds that are visible and ready grow. Unfortunately the new growth does the same thing. I have the plant under a grow light at least 14 hrs a day.
The plant has great sentimental value to my wife as neither her Grandmother or the original rose bush is around any longer. Any advice anyone can offer would be greatly appreciated.
