Q.Ponytail Palm Has Soft Spot Near Bottom Of The Trunk. Is This Cause For Worry Or Treatment?
The tree is at least 15′ tall. I have noticed a soft spot near the bottom of the trunk on one side. Sometimes a piece of bark will fall off. I’m wondering if there is something I can do for it. The tree looks pretty healthy from what I can tell. I am adding some photos. Thanks for any help you can give.

Rot of the caudex has been reported in ponytail palms. Also inspect the bark for insect holes. Has it been receiving more water lately? Overwatering could cause root rot. Try moving the containers away from the trunk, which could be holding water against the tree.
Here is information on how to contact your local extension agent. Give him a call and see if this is a common problem in Florida and if there is anything you can do to correct it. I am not finding much in my research.
