Q.ponytail palm
I have inherited a very large ponytail palm that has been outside since April in WI climate. It recently is showing what I would call “dry rot” on the bulb. What is happening and how can it be corrected? The root system seems to be healthy enough but a quarter of the bulb is like a very dry sponge, porous and easily poked through with your fingers. It may be as big as a 2 inch indentation on the bulb, it looks very poor but the leafy part seems strong and healthy still. Thank you to any advice. MaryEllyn
With the temperatures in April, still quite cold and know that you most likely has some frost during that time period, your plant likely suffered some damage.
If you have soft spots that are that weak on the bulb, it does not sound well for the Ponytail.
I'm afraid there is little to do, as there is not reverse if the bulb portion of the plant is dying.
