Oops! Forgot to tell you what I do about scale on ferns. If you keep an eye on your ferns and catch the scale infestation early, it's easy to scrape the scale armor off with your fingernail. After that, spray the underside of the affected fronds lightly with Pam cooking spray (in the shade or indoors; never in sunlight). Repeat the Pam spray two weeks later. If the infestation has gone on too long and the armor's too thick, Dave's advice is best: Dump the fern and buy a new one.
