Question
My FL yucca tree has black spots on almost every leaf but they otherwise look healthy.  Will I need to cut all of them off or just be careful to keep them cleaned up when they die and fall off?  And can you recommend a good site to identify they type of palm tree I have in my yard?

Answer
Hi Carol,
Don't worry about the yucca unless it starts wilting or dying.  Sometimes, this type of fungus will show up on a plant in a humid area. When it warms up, a lot of the fungus will probably disappear.

Here is a photo guide to palms.

I hope this helps.
Tom
