I have moved the younger kalanchoe up into larger pots, in groupings of five. They are quickly catching up in size to the parent plant (left here, solo in its pot).
It doesn't look like any of my echeveria in the ground outside will come back. Happily, I gave one of those plants to a friend last year and she still has the pot in her windowseat. I asked to break a few leaves off so I could try to restart some again.
