Companion Planting Chart and Guide for Vegetable Gardens (2024)

Keep this Companion Planting Chart! It lists which vegetables, herbs, and flowers are “friends” and grow best in the same bed. Find the best companion plants for tomatoes, potatoes, cucumbers, beans, and all common crops in the homegarden.

Our Garden Planner now shows you the list of companions for each vegetable to make Companion Planting much more accessible when planning your garden bed. See the online Garden Planner.

What Is CompanionPlanting?

Companion planting is when two plants are grown near each other to benefit one of those plants or both–so the benefit can be one way or mutual. This is a tried-and-tested way to reduce pests, attract pollinators, and boost growth! Here are commonexamples.

  • Tomato and Basil are natural companions in the kitchen and garden. Basil repels certain insect pests such as thrips and also disorientates moths, which lay tomatohornworms.
  • Aphids severely crimp your crop! But aphids can’t stand garlic! With this in mind, garlic planted as a barrier keeps crops less vulnerable to pest attack.For example, grow potatoes between rows of garlic to serve as a pungentbodyguard.
  • Nasturtium flowers grown close to kale, cabbage, broccoli, and any brassica crops will lure hungry caterpillars away from eating yourcrops.

7 Benefits of CompanionPlanting

There are plenty more good reasons to plant certain cropstogether:

  1. Deterring pests: Certain plants act as insect repellents or deter critters. For example, garlic’s smell is unappealing to manypests.
  2. Attracting beneficials: Some plants also attract beneficial insects. For example, borage attracts pollinating bees and tiny pest-eatingwasps.
  3. Shade regulation: Large plants provide shade for smaller plants needing sun protection. For example, corn shadeslettuce.
  4. Natural supports: Tall plants, like corn and sunflowers, can support lower-growing, sprawling crops such as cucumbers andpeas.
  5. Improved plant health: When one plant absorbs certain substances from the soil, it may change the soil biochemistry in favor of nearbyplants.
  6. Improving soil fertility:Some crops, like beans, peas, and other legumes, help to make nitrogen more available in the soil. Similarly, plants with long taproots, like burdock, bring up nutrients from deep in the soil, enriching the topsoil to the benefit of shallow-rooted plants.
  7. Weed suppression: Planting sprawling crops like potatoes with tall, upright plants minimizes open areas, where weeds typically takehold.

Evidence-Based Companion PlantingPhilosophy

Until recently, a lot of companion planting was based on little more than hearsay, but there’s an increasing body of scientifically grounded research that actually proves that growing specific plants together can reduce pests, boost growth, and even help wildlife. We’ve collected it all and updated our companion planting chart below! Somebackground:

  1. Traditionally, it was thought that vegetables had “friends” and “foes”—companion plants that either benefitted the vegetables’ growth or impeded it. This isn’t necessarily wrong, but we’ve found that nearly all the associations are positive ones; there are perhaps 2 or 3 “bad” combinations (e.g., black walnut trees, which secrete growth inhibitors through their roots). Bottom-line:there is simply moreevidence for “good” companions than “bad” ones, so we now focus more on why vegetables needfriends!
  2. There are misconceptions about companion planting on the internet, which we found concerning.Many examples of companion planting were based folklore or hearsay. Whileobservations in our own garden can be valuable, we decided that our reference guide should only highlight companion plant pairings backed up by scientific evidence and tried-and-truepractices.
  3. While traditionally, companion planting referred to vegetable plant pairs, we’ve added more flowers to our chart; many are excellent natural insect repellents. Nasturtium is heads and shoulders above them all, taking the brunt of pest attacks. (See more below.) Of course, any nectar-rich flowers such as zinnia, comfrey and ageratum will attract pollinators such as bees to the garden, helping to boost the pollination of flowering crop plants like tomatoes, beans, andsquash.

Examples of the Best CompanionPlants

Here are examples of some of the best companion planting combinations for your garden. (See more in the chartbelow.)

  • Basil and tomatoes as interplanted basil repels thrips, as mentioned above. Basil also deters the moths, which lay tomato hornworms and egg-laying armyworms. Basil also attracts bees, which improves pollination, tomato health, andflavor.
  • Dill attracts ladybugs, which eat small garden pests such as aphids and spidermites.
  • Borage pairs well with tomatoes, attracting pollinating bees. Borage also pairs well with strawberries, enhancing their flavor andvigor.
  • Garlic and garlic spray have a strong scent that deters many insects. Aphids can’t stand garlic! Garlic also repels onion flies, ermine moths, and Japanese beetles. Plant garlic between rows of potatoes as well as alongside lettuces and cabbages and near fruit trees, together with alyssum, to attract aphid-eatinghoverflies.
  • Mint deters aphids, ants, and flea beetles. Just be careful to plant mint nearby in its own pot or bed, as it is a very aggressivegrower!
  • Nasturtiums attract hungry caterpillars away from brassicas like cabbage, broccoli, and kale, so grow these pretty flowers close to those crops; nasturtium also lure black flies away from favabeans.
  • Parsley attracts beneficial insects to protect and pollinate tomatoes. Plant these herbs betweentomatoes.
  • Poached egg plants (a wildflower) draw in hoverflies, which control aphids on nearbylettuce.
  • Sage is a useful herb that repels carrot flies. Also, plant it around a cabbage patch to reduce injury from cabbagemoths.
  • Sunflowers pair well with cucumbers and pole beans: Sunflowers help provide support for climbing plants, as well as shade for crops, which, in hotter climates, can becomesun-stressed.
  • Tansy is a real draw to pest-eating bugs such as ladybugs, ladybirds, and predatory wasps. At the same time, tansy repels many of the common baddies such as cutworm which attacks asparagus, bean, cabbage, carrot, celery, corn, lettuce, pea, pepper, potato, and tomato plants. Tansy is a perennial, which means you only have to plant it once. What more could you want in a gardenflower?

Add more flowers! Growingcalendula or cosmos nearby will attracttiny parasitizing wasps to aphid-hungry hoverflies. And we also love marigolds for drawing in those pest-hungry beneficialbugs.

More Companion GardeningTips

Much of companion planting considers the height of differentvegetables.

  • Lettuce, radishes, and other quick-growing plants sown between hills of melons or winter squash will mature and be harvested long before these vines need morelegroom.
  • Leafy greens like spinach and Swiss chard will grow in the shadow ofcorn.
  • Bush beans tolerate the dapple shade that corn casts and, since their roots occupy different levels in the soil, don’t compete for water andnutrients.
  • Don’t get too fixated with pairing up crops. Correct spacing, sun, water, and good soil management are the most important influences on yourgrowing.
  • Why not start small with a few marigolds and zinnia seeds—and watch the beneficial bugs come! Other options to start with? How about calendula, nasturtium, basil, andborage?

What is the best layout for a vegetable garden? ›

As a general rule, put tall veggies toward the back of the bed, mid-sized ones in the middle, and smaller plants in the front or as a border. Consider adding pollinator plants to attract beneficial insects that can not only help you get a better harvest, but will also prey on garden pests.

Can tomatoes and peppers be planted together? ›

The main benefits of planting peppers and tomatoes together are maximizing yields from a small space, optimizing soil conditions, concentrating water and nutrient needs, and attracting the same pollinators. Both of these veggies can both be trellised to maximize their yields.

What not to plant with peppers? ›

Brassicas: Almanacs and home gardeners recommend avoiding planting brassicas (cabbage, broccoli, kale, collards, cauliflower) near peppers because they require different soil acidity levels and can deter pepper plant growth.

How to group vegetables in a garden? ›

It recommends that you divide crops into four main groups as follows: Legumes (bush beans, peas, pole beans, broad beans); root vegetables (radish, carrot, potato, onion, garlic, beet, rutabaga, sweet potato, shallots); leafy greens (spinach, chard, kale, cabbage, cauliflower, broccoli, spinach); and fruit-bearing( ...

How do I map my vegetable garden? ›

Map Out Your Plants

Sketch out your plan on paper. Use graph paper and draw to scale, keeping in mind the mature size and habit of each kind of plant. Site larger plants, like corn and tomatoes, where they won't cast shade over shorter plants. Choose compact varieties if you have limited space.

How to layout plants in a garden? ›

Place the plants with the distinct form or texture (focal plants) in locations that will lead the eye around the garden. The most common pattern is a triangle shape between three plant beds. Stagger the plants on either side of a pathway in a zigzag pattern to lead the eye forward and draw the viewer into the garden.

Is it better to plant vegetables in rows or groups? ›

If you have the space for it, row gardening allows you to plant more and harvest more vegetables. Squares are limited because if they are too big, you can't reach the plants in the middle. You are also limited in the amount of plants/veggies you can grow in the given space.

Why should you not plant cucumbers near tomatoes? ›

When planting cucumbers and tomatoes together, you must ensure there is enough room between them. Not doing this will mean the plants will compete for light, room and nutrients. 'Space individual plants 18 to 24 inches apart in rows that are spaced between 3 to 4 feet apart.

What not to plant with zucchini? ›

Potatoes can also spread diseases such as late blight, which can also affect zucchinis. Cucumbers and pumpkins should not be planted next to zucchinis as they belong to the same family (Cucurbitaceae) and therefore attract similar pests and diseases.

What 3 plants grow well together? ›

The intercropping method of planting corn, beans, and squash together, commonly called The Three Sisters has been studied and described by scholars in anthropology, history, agriculture, and food studies for many years.

Can tomatoes and cucumbers be planted together? ›

Tomatoes and cucumbers can be grown together successfully, and there are actually some benefits to planting them together. Both plants have similar growing needs when it comes to sunlight, soil conditions, and watering. And if space is at a premium, interplanting the two will allow you to get more out of your garden.
