I have made a terrible mistake with this plant. It was purchased for me without my knowledge at a local succulent show, and it seemed healthy. It was growing well, but towards the end of summer it was looking a little peaky. I looked up some info, and decided to repot. I placed it in a pot with succulent soil and stones to use as ground cover, along with drainage holes in the bottom of the pot and some pebbles at the bottom to encourage proper drainage. I moved shortly after. I placed the plant in a south facing window, blocking the worst of the light with other, more light tolerant plants. However, I accidentally tugged on the plant and the whole plant just came up. I'm unfamiliar with succulent biology, but there does not appear to be any root system. the plant is holding itself together, but not by much. Right now I have it placed on top of some damp soil in it's original pot. Any advice or help would be greatly appreciated.
