Black stuff on leaves

Question

I live in Hawaii. We have black stuff growing on the leaves. What is it and how can I get rid of it?

Answer 1

This is sooty mold. It happens when the plant gets a pest infestation. I would recommend using neem oil, as this will get rid of the sooty mold fungus and kill the pests.
