|Just like humans, there
are certain vegetable plants that are happy with the neighbors, and some
who just can't stand them.
The friendly plants share the burden
of eliminating pests and disease, share their space, and protect one
another. There are some plants that can't stand to be in the same
neighborhood as others. Choosing wisely will assure that your garden
plants are one big, happy family, and producing bumper crops. Many
flowering and foliage plants can be good companions for vegetables, due
to their abilities to repel or eliminate pests of all types.
Nasturtium is a rock star of traps and decoys, and attracts both aphids and the cabbage worms, while creating a diversion away from nearby crops. When trap crop plants become infested and have accomplished their mission in the vegetable patch, they should be removed from the garden. They are very pretty plants, petals taste great in a salad, and they provide pollen and nectar for bees and hummingbirds to pollinate your garden. Have a few planted in pots ready to replace the ones in the vegetable garden that become casualties. This pretty flowering plant does away with aphids, whiteflies, cucumber beetles, squash beetles, Colorado potato beetles and Mexican bean beetles.
A combination of two trap crop species can attract insect pests more effectively. Sunflowers and Nasturtium can be planted together to attract the stink bugs away from bell peppers. The successive planting of second trap crops can extend the period of attractiveness for insect pests. The more, the merrier.
If your trap crops are also being planted as a planned harvest crop, plant more of them in more places, so that the sacrificed plants won't make a dent in the intended crops.

The following is a listing of some of the most popular plants in the vegetable garden that will and will not play well with others.

tomatoes detest your cucumbers.
You will find several references to Brassicas on lists of companion plants. If you're not familiar with the name, they are members of the family of vegetables that includes broccoli, brussels sprouts, cabbage, cauliflower, collard greens, kale, and turnips. These vegetables contain substances that have been proven, in many research studies, to protect humans against cancer. Also referred to as cruciferous vegetables.
Amaranth should be planted with corn to shade the soil and retain water. It also helps attract predatory ground beetles that make short work of garden-damaging insects.
Asparagus gets along well with many plants, and can be planted with basil, cilantro, dill, marigolds, nasturtiums, oregano, parsley, peppers, sage, thyme and tomatoes. Asparagus repels nematodes that attack tomato plants, and tomato plants repel asparagus beetles. Give/Take.
Apples and Apricots - Both love garlic. Garlic helps repel pests. The tree roots also absorb the sulfur produced by the garlic, making the tree more resistant to fungus, mold and black spot. Apples and apricots also love Comfrey, nasturtium flowers, coriander, dill, fennel, basil, lemongrass.
Beans are all
nitrogen fixers of the soil, so they should be planted next to plants of
the Brassica family, carrots, celery, chard, corn, cucumber, eggplant,
peas, potatoes, radish and strawberries.
Beets can be planted next to bush beans, Brassicas, corn, garlic, kohlrabi, leeks, lettuce, mint and potatoes. Avoid planting beets next to pole beans.
Borage repels tomato hornworm and cabbage moth caterpillars, and are great companions for those vegetables. The plant attracts pollinators, so planting it around plants that need pollen to produce, like squashes, melons, and cucumbers. It is also great for the soil and is a superstar in composting.

Tomatoes will bring out the flavor in carrots, but your carrots might be smaller as tomatoes and carrots compete for soil nutrients.
Cherries love garlic just like apples and apricots do. Garlic helps repel pests like the fruit tree bore, aphids and mites. The tree roots also absorb sulfur produced by the garlic, making the tree more resistant to fungus, mold and black spot. Marigolds also live well with cherries, helping to attract pollinators.
Chives do great when planted next to tomatoes and carrots, and it helps bring out their flavors. Also works well when planted next to Brassicas. Chives repel aphids, carrot rust flies and Japanese beetles. They should not be planted next to beans and peas.

Dill improves the health of cabbages and other Brassicas like cauliflower and kale. It is a great companion for corn, cucumbers, lettuce and onions. Avoid planting next to carrots and tomatoes. Dill attracts beneficial insects.
Eggplant is a good companion for amaranth, beans, marigolds, peas, peppers, spinach and thyme. Do not plant next to fennel.
Garlic is a great companion plant for roses to help repel aphids. It is high in sulfur, so it also helps get rid of pests like whiteflies, Japanese beetles, root maggots, carrot rust fly and other non-beneficial bugs. It is a great companion for beets, Brassicas, celery, fruit trees (like apricots, apples and cherries), lettuce, potatoes, strawberries, and tomatoes. Do not plant next to peas.
Lettuce like arugula, radicchio, green leaf lettuce, romaine, like to be planted next to beets, Brassicas, carrots, celery, chervil, cucumbers, dill, garlic, onions, radish, spinach, squash and strawberries.
Marjoram grows well next to all plants, and is believed to stimulate the growth of plants around it. Marjoram particularly loves asparagus. It is very attractive to bees and other pollinators, so it is great planted next to plants that need pollinating like cucumbers and squash.
Mint helps attract earthworms, overflies, and predatory wasps. It also repels cabbage moths, aphids, and flea beetles. Mint is invasive, so it is best planted on its own in containers around a garden. Do not plant near parsley.
Nasturtiums - It is a great companion flower for Brassicas, cucumbers, melons, radishes and tomatoes.

Onions love the herbs chamomile and summer savory to improve their flavor. They also work great alongside beets, Brassicas, carrots, dill, kohlrabi, leeks, lettuce, strawberries and tomatoes. Do not plant near asparagus or peas. Onions help repel the carrot rust fly, hence why they should be planted next to carrots.
Parsley likes to be grown next to asparagus, carrots, chives, corn, lettuce, onions and tomatoes. Allowing some parsley to go to bloom will help attract hoverflies and predatory wasps.
