We have a glorious fan-tail palm about 15 feet tall in our living room. We purchased it from a local nursery a few months ago to replace one that was dripping that honeydew stuff all over our sofa after a terrible ant summer. It was a sad day -- my husband had that palm for years. I don't know much about palms but from what I read the palm aphid leaves a black sooty fungus (or is it palm aphid poop?) that attracts ants or other bugs, which somehow turn the stuff into honeydew?? I know this isn't a great image but can anyone tell me if that is what is on this particular stalk of our palm (or if that is normal for a fan-tail palm) and what we should do about it? I would like to keep the palm healthy and avoid attracting ants into my home.
Fan-tail Palm with black sooty stuff
black sooty mold is a common palm problem, but it is usually SECONDARY to ants and their annoying friends (mealy bugs mostly). To get rid of it, get rid of the ants (not that easy to do) and the mealy bugs. THe black mold itself itn't a serious pathogen, but it is associated with serious pathogens (mealy bugs) and the combination really stresses some palms out. Can lead to bud rot if the mealy bugs get down in there.
