  • There are numerous benefits to companion planting. Plants can attract beneficial insects and pollinators, deter pests, and thus act as insect repellants. They can fend off predators and undesirable wildlife. Raccoons, for instance, dislike the smell of cucumbers.

Jan 29, 2021 To keep it all straight, I created this companion planting chart and planned my square foot garden boxes based the chart. I hope it helps you decide what to plant as well. It's pretty simple: Green means GO, and red means STOP! If the chart says green, the plants work well together. A companion planting guide such as this one will show you which vegetables and flowers support or inhibit the growth of other plants and/or which pests they deter.

Companion planting is one of easiest and most natural ways to set your vegetable garden up for success.

There are many things that go into a successful garden, like good soil, proper sunlight, and timely watering. But one that is often overlooked is practicing the simple basics of companion planting.

The Good Of Companion Planting

What you place where in the garden can have a huge impact on another plant’s health and yields. When vegetable plants are grown near plants they are compatible with, good things occur.

Some plants benefit from the nutrients provided to the soil from their companion partner plants. Others benefit because their companion plants help deter and drive away pests.

In addition, companion plants can also provide support or shade for a fellow variety grown in close proximity. Take for instance, growing lettuce mix underneath tomato plants in mid-summer.

The tomato plants helps in providing shade for the lettuce during the heat of summer. Meanwhile, the lettuce crop acts as a living mulch. Not only conserving moisture in the soil for the tomato plants, but helping keep weeds out too.

The Non-Compatible Side Of Companion Planting

Unfortunately, certain plants can also have a negative effect on others when planted nearby. And it can certainly spell big trouble for their well-being and productivity.

What kind of trouble? Well, for starters, some can stunt the root and foliage growth of other vegetable plants when growing nearby.

Other plants, meanwhile, can attract unwanted pests to a nearby plant that can severely limit harvests.

Good Companion Planting Basics

Garden Planner Companion Planting Plan

So where you do you start when it comes to companion planting basics? It all starts with taking stock of everything you will be growing.

Next, you need to arm yourself with a bit of planting knowledge of what plants do best near others, and which don’t. (We have included some great basic companion partner info in the next section)

From there, you can create a garden plan utilizing simple companion planting basics. Basics that can set the stage for healthier plants, better growth, and bigger harvests!

And those basics go far beyond just planting fellow vegetable plants. Many herbs and flowers can and should be grown in the garden as well for their positive benefits to nearby vegetable plants.


As it turns out, not only are many annuals and herbs beautiful and fragrant, they also are great for repelling common garden pests!

In fact, in our Companion Planting Experiment a few years back in our OWG test garden, it was amazing at just how effective annual flowers can be in keeping a garden safe from pests.

With all of that in mind, here is a look at some of the best relationships between common vegetable plants in the garden.

Companion Planting In The Vegetable Garden

Tomatoes and Peppers

These two garden favorites are wonderful to grow near or with cabbage, carrots, onions, garlic, lettuce and asparagus. But if you really want to help your tomatoes grow, plant basil nearby.

Basil is well-known as a natural deterrent against tomato hornworms, aphids, and beetles. Ind addition, it’s thought that growing basil near tomatoes also helps to improve their flavor

One more benefit to growing basil – it can help to repel mosquitoes. And who wouldn’t like to garden more without those pesky pests!

Always avoid planting peppers and tomatoes near potato plants. Blight and disease can easily be shared and spread between the plants.

Beans, Corn, Cucumbers & Squash

Beans do extremely well when planted with corn. Native Americans used this as part of the “Three Sister” planting method, planting corn, beans and squash together.

As it went, the corn stalks supported the bean vines. Meanwhile, the beans help to fix nitrogen in the soil for the corn. All while the prickly squash vines help keep out racoon and other pests.

Cucumbers and zucchini likewise are excellent crops to grow with beans and corn. Other crops that will do well near beans are potatoes, cucumbers, broccoli, pumpkins and gourds.

When growing beans, two crops to avoid are garlic and onion. Unfortunately, these two crops actually stunt the growth of the beans and can severely limit the harvest.


Plant near beans, corn and radishes. The corn works really well as it provides some shade protection for the cucumbers and allows for the vines to grow up and have support.

Avoid planting cucumbers around potatoes as they can encourage blight in potato crops.


Garlic and Onion

Not only do garlic and onions go well with peppers and tomatoes in the kitchen, they also grow well in the garden together.

Plant onions and garlic near or with tomatoes, peppers, cabbage, carrots, lettuce and basil. In addition to avoiding planting near beans, keep away from peas and strawberries as well.


Members of the broccoli family do well when planted near carrots, and near greens such as lettuce, kale and spinach.


Plant peas with corn, carrots, celery, cucumbers, radishes, tomatoes and turnips. Avoid planting with onions, garlic and shallots.

They can also be planted near carrots, cucumbers. Do not plant directly near the nightshade family plants of potatoes, peppers or tomatoes.

Plant Those Marigolds!

There are many annual flowers that can really help to repel pests. At the top of list are Marigolds. But others such as Alyssum, Zinnias and Nasturtiums all work wonders too.

Marigolds can help protect against an entire cast of vegetable garden pests. That includes aphids, nematodes, tomato hornworms, squash bugs and even cabbage worms. See; Growing Marigolds In The Garden

Even better, they help to keep rabbits, deer and squirrels at a distance too with their strong scent. But if that isn’t enough, consider that marigolds also attract all kinds of beneficial pollinators with their beautiful blooms.

Growing your own fruits and vegetables is a great way to get healthy food and have fun in the process. Whether you are a first-time gardener or a master, knowing what to plant, where to plant it, and in what quantities will all combine to create a successful garden. Additional elements to consider include whether to use raised beds, what items you may want to grow from seed, and what items you might want to transplant.

Space is the name of the game when it comes to plotting out your garden. How big your garden will be is determined first and foremost by the available space you have to devote to it. The second issue to consider is how much food you will likely use during the growing season, as well as any you might want to can, freeze or dehydrate for the winter months.

Another aspect of planning a garden is whether to plant in raised garden beds or use the row garden technique, the latter being the most common. While raised beds may be easier to contain and manage in some respects, individual plant volume is more easily facilitated by the 18-inch-apart rows that are home to single file plants.

As a rule, taller and vining plants such as tomatoes, pole beans, and corn should be planted at the north end or rear of your garden, with smaller plants such as radishes, onions, carrots, beets, and leaf lettuce occupying the south or front end of the garden.

Rules for Green Thumbs

Say you've decided some of the basics above. The three critical requirements for any garden to thrive include plenty of:

  • Sunlight
  • Rich soil
  • Water

Most plants require 6 to 8 hours of sunlight to prosper and keep insects and diseases away. Rich, moist, and well-drained soil with sufficient nutrients is also vital in promoting healthy plant growth. If your soil is only average, you can add compost or other organic material to improve a robust crop yield. Last but not least, having plenty of water available to nourish plants, particularly when they are at the seedling or transplant stage, is critical. Naturally, the closer the water source is to your garden, the easier your watering life will be.

Additional Garden Tips

When planning your garden, use grid paper to create a simple map for what goes where. Keep in mind that plant spacing is determined by the size once the plant is mature. Essentially, no plants' leaves should encroach on an adjacent plant. Instead, they should no more than touch one another.

It is also necessary to learn the range dates for each kind of plant you want to grow. Many have wide date ranges. As such, you will have the option to renew the same crop once the first harvest has been completed or to plant an alternative but suitable crop in its place.

COMPANION FRUITS AND VEGETABLES: Good Neighbors Help Each Other Thrive

Once you've determined what vegetables and fruits you want, it is important to determine their growth compatibility. Just like people, some plants grow better near one another than do others.

The Companion Planting Chart included in this article is designed as a quick reference to make smart choices for plant placement. We have included a brief explanation of how to use the Companion Planting Chart for your convenience.


Good neighbor plants are included in the Plants Grow Well Together category. It is highlighted in dark green much like the richness of spinach and broccoli. Companionable plants growing close to one another thrive by creating mutually beneficial relationships thereby furthering each other's growth.

Our Beneficial to Garden In General category is highlighted in light green, the lively color of celery. As the title implies, these plants provide a healthy foundation for the entire garden.

Plants in the Combination Helps Bug Control category, highlighted in brown, provide an enormously useful function by reducing bug, slug, and other pest infestations that can eat your crops before you get a chance to enjoy them. For gardeners planting fully organic gardens, many of these plant combinations are a 'must' to achieve healthy fruits and vegetables and eliminate pests.

Our Carrots Will Have Good Flavor but Stunted Roots category, bolded in vivid carrot color orange, signifies adjacent plants that have this particular impact on neighboring carrots.


The Don't Plant Together category is in red. Quite simply, stay away from ever planting these items near one another. In short, by following the simple Plant Companion Chart suggestions, you will improve your yield, have a healthy garden, and enjoy fresh fruits and vegetables throughout the summer months. You may even have enough prepared and stored to enjoy during the winter months.
