I have an Aloe Vera plant which looks fine but the main stem is not attached to the roots.
What can I do?  Any ideas?

Hi. I had a similar problem and resolved it by repotting. I discarded the old root put the fresh good leaves in rooting powder and then in fresh potting compost and replanted them. They rooted and I now have a good new plant.  I think the original problem started by me not watering sufficiently. I'd show you a photo of the plant if I knew how to do it!!
