Q.Bismark Palm Tree

Zone Fort Myers Florida | Anonymous added on October 18, 2024 | Answered

My Bismark had 6 foot of flooding due to hurricane Ian. The bottom Looks like it is unraveling and it is black. It has been leaning from the 155 mile winds. The fan leaves look great but it has brown dots not on leaves but on green areas of palm. Is dying? Is the bottom just mold? What can we do if anything to save it? It was planted 4 years ago. Thanks

Some trunk flaring is normal at the base of palms. There could be some rot going on after being inundated with flood water, though. The spots on green areas could be fungal spots and usually do not need treatment. I suggest having an arborist look at the trunk of your tree for advice. The tree is a beautiful specimen and I'd hate for you to lose it.
