Thank you, Farmer's Almanac, for this useful information. Not only is this useful to know to keep bugs & varmints away, but it's also good to know if you have limited space for your garden . . .
- Some plants, especially herbs, act as repellents, confusing insects with their strong odors that mask the scent of the intended host plants.
- Dill and basil planted among tomatoes protect the tomatoes from hornworms, and sage scattered about the cabbage patch reduces injury from cabbage moths.
- Marigolds are as good as gold when grown with just about any garden plant, repelling beetles, nematodes, and even animal pests.
- Some companions act as trap plants, luring insects to themselves. Nasturtiums, for example, are so favored by aphids that the devastating insects will flock to them instead of other plants.
- Carrots, dill, parsley, and parsnip attract garden heroes -- praying mantises, ladybugs, and spiders -- that dine on insect pests.
- Much of companion planting is common sense: Lettuce, radishes, and other quick-growing plants sown between hills of melons or winter squash will mature and be harvested long before these vines need more leg room.
- Leafy greens like spinach and Swiss chard grown in the shadow of corn
- Sunflowers appreciate the dapple shade that corn casts and, since their roots occupy different levels in the soil, don't compete for water and nutrients.
