I've had a ponytail plam for over 10 years now. Unfortunately when I repotted it (quite a while ago now), I didn't realize that the foot was not supposed to be covered with soil. Lately, my ponytail palm had not been doing so well, so I brought it to work as the lighting was better there. Upon putting it into my car, the leafy top (the little that was left of it) broke off. When I took a closer look at the foot of the palm, I noticed that the base was all soft and hollow like. Does anyone know if there is anything I can do to save this plant? I really like it. Any suggestions would be greatly appreciated. Thanks.
