I generally water mine about every 3-4 days depending on how dry the weather has been...kinda like any fern you don't want them to dry out completely or be soaking wet either. If it's been very dry humidity then I mist them also. I usually just spray the whole plant with a gentle hose spray since I have it outside. This winter when I bring it inside I will probably just set it in the kitchen sink and soak it for a little bit every few days....
