Come sit on the porch with me–we’ve got some things to talk about.

I really thought I could plant whatever I wanted, wherever I wanted…. And it would all just work out.

SPOILER ALERT: It did not.😡

I used to think that as long as my plants had sun, water, and good soil, they’d all just do their thang. Turns out, some plants are besties, and some are frenemies.

Companion planting is one of the easiest ways to improve your garden by pairing plants that grow well together.

Not everything in your garden is going to get along, no matter how much you want it to. Some plants help each other thrive, and others compete like siblings fighting over the remote.

And if you don’t know the difference, your garden WILL let you know real quick. Some plants benefit each other in different ways, some compete against each other, while others attract the same pests and diseases.

So let’s talk about companion planting- what works, what doesn’t, and how to avoid a little unnecessary garden drama!

What is Companion Planting?

Companion planting is simply the practice of intentionally growing certain plants together to help each other thrive. It’s essentially matchmaking for your garden.

Some plants work really well together-they support each other, help with pests, and grow better side by side. Others? Not so much. They compete, struggle, and make things harder than they need to be.

The goal is to pair plants in a way that benefits both… not create beef and turf wars.

Benefits of Companion Planting

Here are a few ways companion planting can help:
•Natural Pest Control: Some plants help repel pests or distract them from your main crops.
•Attract Beneficial Bugs: Pollinators seem to be more attracted to some plants than others. So planting some of those plants in with your veggies can bring them in and help pollinate!
•Better Growth: Certain plants can support each other and improve overall health.
•Enhance Flavor: Some say that planting basil with your tomaters can help enhance their flavor!
•Improved Use of Space: You can grow more in the same area by pairing veggies with herbs and flowers.
•Healthier Soil: Some plants help add nutrients back into the soil, like beans! This feeds the other plants in the area.
•Provide Shade: Taller plants can provide shade for those that don’t like the afternoon heat much. These taller plants can also help you extend the season for your cooler weather crops, such as dill or cilantro.
•Stronger, More Resilient Plants: A balanced garden tends to handle stress better

It’s not magic, but it sure seems like it! It can make a noticeable difference when you get it right. When you put the right plants together, your garden can start to feel a whole lot less chaotic. It’s not about being perfect, it’s about giving your plants a better chance to thrive without making things harder than they need to be.

Plants That Grow Well Together

Some plants really do make great neighbors. I can’t possibly list them all, but I can provide you a place to start!

🍅Tomatoes and Basil → Basil can help repel pests, such as aphids, mosquitos, some beetles, and those pesky tomato hornworms! And like I mentioned before, it’s thought that basil improves the flavor of tomaters. Plus, they just belong together, in the garden and in the kitchen. (Caprese Salad anyone?!)

🥕Carrots and Onions → Onions help deter carrot flies, slugs, snails, and other pests that like to munch on your carrots.

🫛Beans and Cucumbers → Beans add nitrogen back into the soil, while cucumbers benefit from the extra nutrients. Honestly though, you can plant beans with most plants for this reason!

🥬Lettuce and Radishes → Radishes can grow pretty quickly, especially breakfast radishes. They help break up the soil, while lettuce provides them some shade to keep them cool.

🌽Corn and Beans and Squash → The three sisters! Corn provides support, beans add nitrogen to the soil, and squash shades the ground.

These kinds of pairings help create a more balanced garden where plants support each other, instead of… pushing each other out in front of a bus. (And yes. Cady Heron swears she didn’t push Regina George in front of the bus. Allegedly.)

Plants That Should NOT Be Planted Together

Now.. Not all plants are meant to be neighbors. Some prefer an HOA, some prefer freedom from restraints put on them by others. Fact of the matter is, not all plants are going to get along, and that’s okay.

Some will compete, stunt each other’s growth, or just make your life harder than it needs to be. So here are a few combos you might want to avoid:

→ Tomatoes and Corn: They attract similar pests. And lawd knows here in the south we don’t need any more dang pests!
→ Onions and Beans: Onions emit sulfur compounds, which can stunt the growth of beans.
→ Carrots and Dill: Dill can interfere with carrot growth, and attracts carrot rust flies, as well as a few other pests that will terrorize your carrots. Dill and carrots also compete for the same nutrients. So while these two are in the same family, they are NOT friends.
→ Potatoes and Tomatoes: Both are prone to similar diseases, which can spread more easily when planted together.

And honestly? You don’t have to figure it all out at once.

That’s exactly why I’m starting my “Porch Talk” series.

Each week, I’ll be spotlighting one plant—sharing facts, do’s and don’ts, and what grows well with it… and what definitely doesn’t.

At the end of the day, companion planting isn’t about memorizing a giant list-it’s about understanding which plants help each other and which ones don’t.

Start simple, pay attention to how your garden responds, and adjust as you go. You’ll learn what works in your space, what doesn’t, and probably have a few “Well, that didn’t go as planned” moments along the way.

That’s just part of gardening.

The goal isn’t perfection, it’s progress.

Comment some of your favorite plant combos! I’d love to hear what y’all are planting this season!
