I bought these miniature roses about 3 months ago from the supermarket, so I was aware they might not live long. However, they seemed to do well. After I removed the dead flowers and moved them near the window, they started growing new leaves, they almost doubled their size. I was very surprised that they also bloomed again.
In the last days I started to notice that their leaves are slowly turning yellow, starting from the bottom. Here are some pictures of them where you can see the leaves:
Are they dying? Should I plant them outside? The temperature outside is about 20C during day and around 10C during night, not very sunny unfortunately.
