I have had a mini rose since last February and has been doing well so after Valentines was over, I found another that I decided to take home and did the same two weeks later to another new rose plant. I repotted them both and placed them next to the first one. They are all in a south facing window, where my first plant has seemed to thrive. One of the new ones started dropping leaves at the bottom and is slowly working its way up each stem, dropping leaves. Some are starting to yellow while others seem green still. No idea what to do or what is going on since I have had a lot of luck with my first rose.
