26 Plants to Grow Side-By-Side
Experienced gardeners know that a diverse mix of plants ensures a healthy and beautiful garden. Many believe that certain combinations of plants have extraordinary (even mysterious) powers to help each other grow. Scientific investigation of the process, called accompanying planting,
Companions help each other to grow and use the garden space efficiently. Tall plants, for example, provide shade for shorter plants that are sensitive to the sun. Grapevines can cover the ground while tall stems grow up into the sky, so two plants can take the same stain.
Some clutches also prevent pest problems. Plants can ward off harmful organisms or lure the evil beetles away from more sensitive species.
These combinations of plants together make a lot better:
Roses and garlic
Gardeners have been planting garlic with roses for eons, as the onions can help ward off pests of roses. Garlic chives are probably just as repellent, and their small purple or white flowers in late spring go well with rose petals and foliage.
Marigolds and melons
Certain marigold varieties fight nematodes in the melon roots without chemical treatment.
Tomatoes and cabbage
Tomatoes repel diamond moth larvae, which can chew large holes in cabbage leaves.
Cucumbers and nasturtiums
The nasturtium vines make it a great companion between your growing cucumbers and pumpkin plants, suggests Sally Jean Cunningham, gardener and author of Great garden companion. Nasturtiums allegedly repel cucumber beetles, but can also serve as a habitat for predatory insects such as spiders and ground beetles.
Bell pepper and pork cabbage
In a study at the Coastal Plains Experiment Station in Tifton, Georgia, leaf miners preferred both hogweed (also called amaranthus) and ragweed over pepper plants. Just be sure to remove the flowers before the weed seeds.
Cabbage and dill
“Dill is a great companion for cabbage family plants like broccoli and Brussels sprouts,” says Cunningham. The cabbages support the floppy dill, while the dill attracts the helpful wasps that fight cabbage worms and other pests.
Corn and beans
The beans attract useful insects that hunt corn pests such as cicadas, fallworms, and leaf beetles. The vines can also climb up the corn stalks.
Lettuce and tall flowers
Nicotiana (blooming tobacco) and Cleome (spider flower) give the salad the light shade in which it grows best.
Radishes and spinach
When you plant radishes in your spinach, the leaf miners are pulled away from the healthy greens. The damage the Leafminers do to radish leaves does not prevent the radishes from growing nicely underground.
Potatoes and sweet alyssum
The sweet alyssum has tiny flowers that attract gentlylike predatory wasps. Plant sweet alyssum next to bushy plants like potatoes, or let it spread out to form a lively ground cover under arched plants like broccoli. Bonus: The sweet fragrance of the Alyssum smells your garden all the way.
Cauliflower and dwarf zinnias
The nectar from the dwarf zinnias attracts ladybugs and other predators that help protect the cauliflower.
Collards and catnip
Studies have shown that planting catnip alongside collards reduces flea beetle damage on the collards. The fragrant plant can also help repel mosquitoes.
Strawberries and Love-In-A-Mist
Big, blue blooming love in the fog (Nigella damascena) “looks wonderful planted in the middle of a wide array of strawberries,” says Cunningham.
