I have been catching up on my garden reading here in Zone 6. One of the things I picked up at the library was a DVD on tree and shrub care. Among the things it said to do was to use a 'clean-up tonic' once every two weeks to discourage insects and diseases. The DVD made it sound like a very good thing to do.
Clean-Up Tonic
1 Cup lemon-scented liquid dish soap 1 Cup of antiseptic mouthwash 1 Cup of chewing tobacco teaThe tobacco concerns me, specifically tobacco mosaic virus. Will this treatment spread the virus? According to sources online TMV infects and kills tomatoes/peppers/eggplant/ cubits, annual flowers, orchids, and hundreds of other ornamentals.
