My husband came home with 3 pots of miniature roses. They were beautiful - but no care instructions came with them. Two didn't even say what kind they are. The leaves are turning brown. I've tried watering - letting them go dry. Putting them in the windowsill, taking them out. The still seem to be blooming - maybe the leaves are supposed to be brown? I've never had roses before, and I love them. I just don't know what to do with them. Eventually, I would like to plant them outside if I can. Any help would be appreciated!
