Companion Plants
Your "Good Neighbor" Plants


Companion plants mean the plants lend a hand in each other’s growth. Which plant enhances? Which repels? For instance, certain aromatic plants repel harmful insects but adversely affect other plants. Note likewise that you may need to experiment with companion plants. They are affected by your gardening habits, soil types, plant varieties, microclimates, etc.


Aromatic Plants
They are companion plants to cabbage. Aromatic plants ward off cabbage worms. Plant yarrow near your aromatic herbs to enhance their indispensable oil production.

Asparagus
Asparagus appreciates tomatoes, parsley, basil, nasturnium, and marigold. Parsley and basil protect asparagus from the asparagus beetle. Do not interplant asparagus with onions, chives, garlic, leek, or mint.

Basil
Basil helps not only the flavor and growth of tomatoes, it also repels tomato hookworms. It keeps at bay mites, aphids, asparagus beetles, and flying insects like gnats. Basil is also a companion plant to asparagus, cabbage, pepper, and beans. Rue and basil do not like each other.

Beans
They are companion plants to carrots, cauliflower, cucumbers, potatoes and most other herbs and vegetables. Bush beans and strawberries thrive well together. Do not plant beans with fennel, onion, kohlrabi, and basil. Avoid planting pole beans with sunflower, beets, and cabbage. (Note: fennel is incompatible with most plants.)

Bee Balm
Bee balm is a companion plant to tomatoes, assisting them with growth and flavor. Do not plant with field mustard.

Beets
Beets are a companion plant to lettuce, the cabbage family, the onion family, bush beans, kohlrabi, sage, and radish. Beets dislike mustard and pole beans.

Borage
It wards off tomato worms and appeals to bees. It is also a companion plant to strawberries and squash.

Catnip
As a border, catnip is a companion plant to what you have and will safeguard them against flea beetles, Japanese beetles, aphids, cockroaches, and ants. Catnip especially likes eggplants. Catnip has nepetalactone, a compound that affects a cat's behavior.

Chamomille
It goes well with squash, cabbage, and onions. Onions are also companion plants to lettuce. They guard against slugs.

Dill
It is a companion plant to cabbage, lettuce, the onion family, and garlic. Dill is incompatible with tomatoes, caraway, and carrots.

Marigold
Freely plant marigolds as companion plants. They free your soil of nematodes, and repel tomato worms, asparagus beetles, etc.

Peas
They are companion plants with most vegetables. They also help build nitrogen to the soil. Peas are not compatible with the onion family, potato, and gladiolus.

Tansy and Garlic
They are companion plants working together to fend off insects that prey on roses and raspberries. Some of these pests are aphids, borers, fruit moths, ants, Japanese beetles, and spider mites.

Tarragon
An all-around friend.

Tomatoes and the Cabbage Family
Do not plant tomatoes and the cabbage family together. They are not companion plants as they inhibit each other’s growth.

Wormwood
It repels cats and other animals. Plant wormwood as a border to keep them away from your garden. Wormwood is also a moth repellant.

Beginning Gardeners
With companion planting, you can cultivate a mixture of neighborly crops. If you are new at gardening, be observant. Notice growth traits, root formation, soil demands, and especially the scent. You will learn fast! The smell of the plants determines which insects visit your balcony garden. Your garden will thrive if your companion plants are good neighbors to each other!
