When it rains, go out and grab the plant by the base of the trunk and shake the shit out of it. In heavy, heavy rains I do it while it's raining and after. Has always worked good for me, and helps to prevent mold.
Or if the plant is in the shade for the first few morning hours, go and shake the dew off from it.
