graced the world with this
thought:


For the last two years (I'm not bothering this year) all my brassicas
have been covered in whitefly. I always thought this was a greenhouse
pest, not outdoors. Does anyone have a basically organic method of
prevention/cure. The whitefly are persisting even after fairly sharp
frosts.

Take pieces of cardboard, paint them yellow. When they dry, mop on a
coat of cooking oil with a paper towel or sponge. Set them out in the
garden, the whiteflies will be attracted to them and stick.
