Question
I have a large fern in my office, about 4' tall that has a cottony white substance all over it. It looked like white flies at first, but nothing moves, so I assume it's a fungus. Any idea what it is and what I can do?  I'd be very grateful.

Answer
That is foliar mealy bugs.  The best way to get rid of them is to get a q tip dipped in rubbing alochol.  Touch the q tip to the white stuff and take it off.  Keep doing it until they are gone.  This is the only full proof way to get rid of them.

Happy Growing
