[INDOOR-GARDENING:223] Re: Scale problem

Another way I work on scale in large species Begonias,  I have a B
vitifolia that is a scale magnet.  I was told to keep a spray bottle with
isopropal alcohol nearby and spray the *** out of it about every three
days.  Be sure to get under and on top of the leaves.  It works on thick
stem begonias,  I have not tried it on anything else.
