I recently had to be gone for a while and the person caring for my plants didn't water them enough. I have several brown/dead leaves on my fern. Do I pluck them off? Or allow them to fall of naturally? It is a rather large fern, and does not seem to be happy in its current placement, so I am also moving it. But I am moving it to a corner near a window, so how often should the plant be turned to allow it to get adequate light all the way around?
