I mentioned companion planting in a previous post Starting a Small Garden. What is companion planting? It’s when plants benefit from being grown together. Yes, some plants do not belong together.You may be surprised—like I was—to find out what plants can be grown together and how they can help each other thrive..

🌱Pairing The Right Plants Together

Why should you be worried about companion planting? Pairing the right plants together is an important aspect of gardening, especially if you’re growing edible plants. It’s more than just placing veggies side by side. It’s a thoughtful method of growing plants in combinations that will benefit each species.

Companion plants may:

• Repel pests naturally (no chemicals needed!)
• Attract beneficial insects like pollinators or pest-eating bugs
• Benefit the growth of another plant
• Improve their partner’s flavor

For example, planting basil near tomatoes doesn’t just help repel tomato hornworms—it’s also believed to make the tomatoes taste even better. Now that’s a win-win.

By understanding plant relationships, we can create a healthier, more vibrant garden. Less spraying, more harvesting. 🌞🌿

🥕 Common Companion Plant Examples

Here are some common companion planting pairs, including how they help each other out:

• Tomatoes and Basil – Are natural companions in the kitchen and garden. Basil’s strong aroma repels certain insect pests, such as thrips, and also disorients moths that lay tomato hornworms.
• Carrots and Onions – Carrots repel onion flies, and onions help keep carrot flies at bay. It’s like a little garden buddy system
• Radish and Cucumbers – Radishes deters cucumber beetles, and cucumbers provides cooling shade for the radishes.
• Corn, Beans, and Squash: The classic “Three Sisters” combo. Corn grows tall, giving peas, beans something to climb on, while the squash plants grow big and spreads across the ground, suppressing weeds and keeping moisture in.
• Dill – Dill is good to plant with cabbage, or corn. It attracts beneficial insects like Ladybugs, and Parasite Wasp (Dirt Dobbers) that help deter insects like cabbage worms, aphids, earworms, etc.  
• Mint – While mint can get wild if left unchecked, it does a great job deterring deer and repelling some insect pests. I recommend planting in containers so it doesn’t take over!
• Natural supports—Tall plants like sunflowers, corn or even okra can act as natural supports for lower-growing vining crops such as cucumbers and peas.

🌼 Flower Partnerships

Flowers aren’t just for looking pretty—they’re powerful garden allies! Mixing flowers into your vegetable garden attracts pollinators, keeps pests in check, and adds vibrant color. Here are some of my favorites:

• Marigolds pair with many vegetables, herbs, and other flowers, primarily for their pest control properties. I love marigolds; they are one of my favorite flowers to plant in the garden. They partner well with tomatoes, cucumbers, melons, potatoes, lettuce, squashes, strawberries, peppers, kale, basil, lavendar, thyme, sage, and many others.
• Borage is a cucumber-flavored herb that repels corn’s pests and attracts pollinators, making it a great companion for corn.
• Sunflowers – Plant corn and sunflowers together for pollinator benefits or rotate them yearly to improve soil nutrients.
• Lavendar – Lavendar attracts pollinators like bees and butterflies, enhances the growth of nearby plants, and repels certain pests. Lavender’s strong scent can also deter some pests, like deer, and it’s a visually appealing plant to incorporate into a garden.
• Daisy – Flowers in the daisy family, especially chamomile, will attract a range of beneficial insects. 
  

📝Keep a Garden journal

One thing I always recommend is keeping a garden journal. It doesn’t have to be fancy—just a notebook where you can jot down what you planted, where, and how it did. Write down what companion plant combinations worked (and what didn’t), what pests showed up, and what flowers seemed to attract the most bees. Every season teaches you something new, and your journal becomes a treasure trove of wisdom.

Over the years, My husband flips back through old entries to remember what variety of squash handled our Georgia heat the best or which row of tomatoes seemed happiest next to basil and marigolds. Trust me, you’ll be glad you wrote it down.

 The Farmer’s Almanac is a great resource for all things gardening. It’s a great resource for planning out your companion planting. We try to plant in both spring and fall. We often refer to their planting calendars and tips when sketching out our garden beds each year.

🌾 More Than Just Bigger Harvests

Companion planting isn’t just about boosting yields—it’s about working with nature, not against it. It leads to:

• Fewer chemical pesticides and herbicides
• Healthier, more resilient plants
• A thriving ecosystem filled with bees, butterflies, and beneficial bugs
• A garden that feels alive and balanced

It’s one of those gardening techniques that once you try, you’ll never go back. And honestly, it’s just plain fun to watch how the plants work together like old friends helping each other out. From sunflowers shading lettuce to dill protecting the cabbage, it’s like the garden has its own little community going on.

🌻 Final Thoughts

If you’re just getting started with companion planting, start small. Try a few known pairs like tomatoes and basil or carrots and onions. Add in some flowers like marigolds or chamomile, and watch what happens. You don’t need a massive plot—this works in containers and raised beds too!

And don’t stress if something doesn’t go quite right. Gardening is always a learning process. What works one year might flop the next—and that’s okay. Keep experimenting, keep learning, and most of all, enjoy the journey.

Companion planting has transformed the way I garden. It’s given me healthier plants, happier pollinators, and more delicious harvests with a little less work. Give it a try this season—you might just fall in love with the magic of plant partnerships.
