Elaine, I’m trying to picture this. Is there just lots of brown stem between the surface of the soil and where the green starts? I think when you repot it you will find that it is pretty pot bound. You can take an inch or so off the bottom of the root ball with a sharp knife and then set the whole thing lower in the soil so that the brown is buried. You could also divide it at this time by cutting the plant into two or more pieces.
