Happy Together, a song that the Turtles had on the charts in 1967 is appropre when it comes to plants. Some plants do extremely well when planted together; other plants just give up when planted closely with plants they donít care for.

Here's some suggestions for Companion Planting; plants that will enhance each other and plants that can't stand each other.
Basil, Parsley, Tomato
Parsley and asparagus are mutually beneficial in promoting one another's health and vigor; Tomatoes contain a substance called solanine, which protects against asparagus beetles, but tomatoes also attract the natural predators of the asparagus beetle. Asparagus Rust, Fusarium, Needle Blight, Purple Spot. Pests: Asparagus Aphid, Asparagus Beetles.
Only scented Marigolds will work, but not the Mexican variety: they act as a herbicide on beans and cabbage; Carrots help beans, but beans don't help carrots; Strawberries and bush beans grow much better together than separately.
Grapes, Mexican marigolds, Pole Beans, Rue, Strawberries, Tomato.
Mint is very invasive, but it enhances growth and health and discourages aphids, ants, flea beetles, white cabbage moths and even bunnies and other rodents; Marigolds must be scented to ward off insects, but not the Mexican variety, which acts as a herbicide on cabbage and beans; Rosemary and Sage deter cabbage moths; Thyme deters the cabbageworm; Garlic wards off pests; Chamomile improves the flavor of cabbage and enriches the soil with calcium, potassium and sulfur; Cabbage and grapes are ‘natural enemies' - chemical warfare may be involved.
Sunflower increases corn yield and relieves fall army worm/corn protects sunflower from insects; Ground vine plants shade the soil, aiding in moisture retention and their prickly vines may discourage raccoons and other corn predators; Climbing vine plants help anchor the corn stalk and make it less vulnerable to wind damage; Geranium repels Japanese beetles and cabbage worms; Peas and beans replenish nitrogen in the soil; Tomatoes and corn are subject to the same pest, the tomato fruit worm/corn earworm.
Bush beans protect against the Colorado potato beetle; the potato protects the bean against the Mexican bean beetle; Flax contains tannin that repels the Colorado Potato Bug; Tomatoes make potatoes more susceptible to potato blight; Raspberries make potatoes susceptible to blight; Flax enhances growth and repels the Colorado potato beetle.
Boxwood and other woody plants with prolific root systems
Garlic causes roses to produce a stronger perfume; Parsley protects against rose beetles; Onions repel rose chaffers; Lupines increase soil nitrogen and invite earthworms; Tomatoes protect from black spot disease; Hyssop deters flea beetles and cabbage moths; Woody plants with large root systems will compete for soil nutrients. Taste of cabbage and beans is improved by Rosemary; Grows well with sage.
Beans, Cabbage, Carrot, Sage
Taste of cabbage and beans is improved by Rosemary; Grows well with sage.
Basil improves flavor and protects against insects; Horehound encourages fruiting; Bee Balm aids in both growth and flavor (caution: Bee Balm is a mint and is invasive!); Potatoes inhibit the growth of tomatoes.
May be planted with all plants. It enhances the fragrance of other herbs, protects against insects, improved taste of companion vegetables, and is an all-around nice and useful plant.
