At St John's, there are several pot plants that have been sitting in the greenhouse for years. We noticed that an Aloe Vera had got a bit overcrowded in its pot and that several little babies were fighting for space.
So we took it out of its pot, separated the different plants and re-potted them. The roots on these things are amazing, up to 5 feet long, wrapped round and round the pot, I can see how they survive in the desert. Let's just hope they'll survive the re-potting.
