I just noticed that my ponytail palm bulb has shrunk or collapsed. The plant is in a small pot with the bulb about 4 inches in diameter. But now part of the bulb looks deflated! There is no sign of root rot as I have not watered the plant for a long time. The leaves on top looked green and the rest of the caudex is still normal except for the deflated shrunk area. We had a hot spell of over 100F for 2 days this week and a few days of 100F since New's Years Day. I am wondering if it has used up its' storage of water. Can anyone advise what I should do? I have just watered it and will be observing how it will be doing. Will the caudex be restored? Thanks for your advice.
