I have a Sempervivum and it was doing great, it even shot out a stem with pretty small pink flowers, but after the bloom fell off the leaves started dropping too. One by one they all fell off but two. One of the two remaining leaves has new growth on it and a long shoot coming from it and the stem of the original plant has roots coming from one side. I did get one leaf off that started a new plant but now I have no clue what to do about the bare stem. I have just been leaving it completely alone for now so I don't end up killing off the new growth but I think it is time to do something. I will attach photos of it from when I got it when it bloomed and what is going on now. I thought when I first got the plant that it was way too wet but soon after I took the first photo attached I went out and got cacti and succulent soil and re-potted it. I only water my succulents once every other week but I do live in Mobile AL (deep south east US) on the cost so it is very very humid here even inside.
