Since someone mentioned Aphids, yes they are Fukien Common on this species (get the joke?).
Using a systemic insecticide and occasional fungus spray along with full sun and good air circulation will keep this from happening. They are completely preventable entirely and any infestation of them on your trees just means you need the systemic insecticide pellets as part of your tool belt of knowledge. Certain trees always get systemics in my garden. Fukien Teas. Crepe Myrtles. Prevention is much easier than repair! Which systemic? Unknown for your back yard, I know what I use, but ask your club what is best for where you are. After all, I have no idea if you are my neighbor in Orlando or if you are from China because you failed to fill out your profile enough for anyone to give you more *specific* help.
