Tomato 'Gigantomo' Companion Plants

Interplanting your tomatoes with other strong scented plants can help to mask the tomato plant from unwanted pests. Examples of these are the onion family (Chives, Garlic) and the mints (Spearmint, Oregano and Basil). The best known and most commonly used is Tagetes patula (French marigold), although some believe it can subtly change the flavour of the fruit. Grow Borage, Queens Anne Lace, Parsley and Dill to protect against Tomato Hornworm. These flowers will attract adult parasitic wasps and other predatory flies that feed on their umbellifer flowers. The larvae of these wasps feed on the Tomato hornworm, while the flies will feed ob various tomato pests. Asparagus produces Asparagus acid. When grown near tomato plants, this acid will repel nematodes that are known to attack. Tomato plants also protect Asparagus as they contain Solanine, a type of poison that kills the Asparagus beetle. Ground cover plants, including mints, stabilize moisture loss round tomato plants and other Solanaceae, which come from very humid climates, these can help prevent moisture-related problems like blossom end rot.
