Companion gardening is a great way to help your plants thrive and, using their natural defenses, help you grow organic more easily. From vegetables to herbs, to flowers, all plants grow better next to a companion.

But just like people, not any companion will do. Planting the wrong plants next to each other can do more harm than good. Knowing what plants work well together is an important part of a successful garden.

Companion planting has several amazing benefits that can help your vegetable garden flourish if planted right. Let’s take a look.

Benefits of Vegetable Companion Planting

Knowing which plants grow best near others and why will help you to setup a garden in the healthiest way.

Benefit #1. Pest Control

It’s amazing that certain plants when planted near other plants will help to protect from pests in the garden.

Pests will have a more difficult time finding a patch of their favorite plant if it’s protected by a plant they don’t like. And some plants, like herbs and flowers, put off a naturally deterrent scent. 

For instance, planting marigolds next to a patch of beans can help deter bean beetles, and if you plant them near tomatoes, they will keep away Hornworm Caterpillars, the creepy guys.

Keeping pests out of your garden naturally allows you to grow organic with more ease.

Benefit #2. Support

Some plants can provide the necessary support for each other while they grow. The ancient Cherokee Indian practice of three sisters helps to provide a nice harvest of three vegetable companion plants.

Plant corn first and allow it time to grow a few inches, then plant squash and beans. The corn will provide a natural trellis for beans. The beans will feed the necessary nitrogen needed to the corn. And the squash grows along the ground keeping weeds out and providing shade for the bean and corn roots. They also repel each other’s pests.

Planning your garden so that plants can support each other allows you to plant more and provides a better harvest.

Benefit #3. Saves Space

If your garden area is small, companion planting will help you make the most of your space.

You can plant a ground growing vining plant under a taller plant to fill in space that would otherwise allow weeds to grow. Or you can grow fast-growing crops between slower growing ones.

For instance, radishes and green onions grow quickly. Plant them into any empty area around plants that will take a while to sprout, like lettuces, and they’ll be ready to harvest before your other plants start to fill up space.

This really is helpful if you are planting a container garden on your back porch. The more you can grow in your containers the more you can enjoy all summer long.

Benefit #4. Keeps the Soil Moist

Vegetable companion plants can help keep their partners well nourished. Vining plants like squash and cucumbers provide shade to the soil around other plants so moisture stays in the soil instead of evaporating.

If you experience long droughts in the summer, this will help to keep your garden healthy without the need to constantly water it.

Benefit #5. Reduces Weeds

There is nothing I dread more than weeding and if there is anything I can do, such as companion gardening, to cut down on it, I am game.

Covering the ground with vining plants does more than just shade the soil and keep moisture in, it also helps to prevent weed growth.

Cucumbers and squash are excellent crops to keep your garden weed-free. If the ground is covered, there’s no place for the weeds to grow.

Benefit #6. Helps with Disease Issues

When you have a large grouping of the same type of plant, disease spreads easier and faster among that plant. Adding a variety of plants to your garden can break up the grouping and slow down the spread of diseases.

Some plants even help others by making them less susceptible to disease. Take a look at the three sisters’ method that I talked about above. By planting this way, you can use the beans to provide healthy nitrogen to the corn. Another good example is growing basil with tomatoes; it makes your tomato plants healthier.

Putting plants to work for you is another great way to grow a bigger and healthier garden. 

Benefit #7. Attracts Pollinators and Beneficial Insects

Mother nature is at it again, and she has provided us with some insects are actually beneficial to your garden and can help it produce a bigger crop. These insects are more likely to spend time in your garden if they have something good to nibble on and a good environment.

Spreading flowering cover around your garden can welcome these beneficial insects in. Good examples of flowering covers include clover, buckwheat, and vetch. To make the most of this planting method, choose varieties that have extended bloom periods.

Benefit #8. Provides Natural Trellises

We’ve looked at using corn as a trellis in the three sisters’ example, but there are other plants that can serve as a trellis for tall plants. Companion flowers, Jerusalem artichokes, sorghum, amaranth, fruit trees, and nut trees are all good plants for providing a natural trellis.

Benefit #9. Improves Flavors

Basil is a great companion plant for many types of plants. It’s especially good to plant with lettuce and tomatoes because it improves the flavor of them. As an added bonus, it also repels mosquitos.

An added bonus of companion planting is there are a variety of companion plants that will improve the flavor of the plants they’re grown near.

Benefit #10. Allows for More Variety

You can plant a few varieties of beans, tomatoes, peppers, or almost any other kind of vegetable in areas you need to fill-in. Using the vegetable companion planting method, you’ll be able to plant more of a variety of plants and use them to benefit your other plants.

With all the benefits of companion vegetable gardening, it only makes sense to use this planting method. After all, it benefits your plants, allows you to grow better crops, and allows you to garden organically with little effort.

But, as we mentioned earlier, there are some companion gardening plants that don’t do well together. Beans should not be grown near onions; they are better planted with corn, marigolds, or potatoes as these plants will protect them from Mexican bean beetles. Onions are, however, great partners for tomatoes and carrots.

And tomatoes grow well with carrots and basil. In fact, tomatoes provide great shade for plants like onions and carrots. They keep the soil from getting too hot.

Cucumbers should avoid the company of potatoes, but love to be paired with beans, cabbage, corn, and radishes.

Peppers flourish with carrots, onions, parsley, tomatoes, and basil but should be kept away from cabbage or fennel.

And garlic should never be grown near peas or beans, but it does well with cabbage, tomatoes, and most kinds of fruit trees.

Herbs grow well with almost anything so it’s a great idea to intermix them around your garden. They deter pests and they’re friendly with almost all types of plants. A few herb companions to avoid include:

  • Oregano, parsley, thyme, and sage with cucumbers
  • Rosemary and dill with carrots

Let’s take a look at some good vegetable/herb companions:

  • Rosemary makes a great companion for beans, cabbage, and carrots.
  • Parsley is great with corn, tomatoes, and even roses.
  • Sage works well with carrots, cabbage, and tomatoes. In fact, tomatoes tend to grow better when sage and basil are nearby.
  • Dill enhances the flavor of cabbage, cucumbers, lettuce, and onions.

When it comes to companion gardening, the best way to plant is to plan ahead. Decide what kinds of plants you want to grow, how long they take to harvest, and research what plants grow well (or don’t grow well) together. Planning ahead will allow you success from the start.

Plants that harvest early can be planted between plants that take longer to grow, allowing you more useable space in your garden. And planting using the three sisters method will also provide more space by growing three plants in the same area and allowing them to benefit each other in their growth.
