Spraying oil when it's cool or shady just makes sense to me. What happens
when you heat oil in a pan? Yup, it sizzles. I know some people think of
orchids as food, but personally I'd rather not cook 'em. In any event, the
white fly problem seems to have confined itself to my husband's veggies
(whew, wipe sweat off brow!) and Ultra Fine seems to be handling it.

;oD
