Looking to give your peppers some good company? You’re in the right spot. Whether you’re just starting your first garden bed or you’ve already lost a shoe to the mud at least once this season (no judgment), learning about companion plants for peppers will change how you think about your vegetable garden.
Companion planting is just a fancy way of saying “let your plants be good neighbors.” Peppers—those spicy jalapenos, sweet bells, or fiery habaneros—will survive with the right mix of sunlight, soil, and water. BUT, they'll thrive when surrounded by buddies that protect them, attract pollinators, and keep those hungry bugs at bay.
Let's look at which plants make the best sidekicks for your peppers, which ones to avoid, and a few down-to-earth tips to keep the whole thing simple and fun.
Why Peppers Love Company: Companion Planting Made Simple
Companion planting isn’t rocket science. Plop a few helpful herbs or friendly veggies nearby, and suddenly you’ve got fewer pests, better-tasting peppers, and a garden bed that looks like you really (almost) know what you’re doing.
There’s no need to feel overwhelmed. I remember when I first tried to plan out my gardens using companion planting, thinking I had to follow complicated charts and rules. Let me save you the stress: companion planting is flexible, not another thing to obsess over.
It’s okay to experiment, and honestly, it’s a whole lot of fun seeing what works in your own backyard. So, let’s keep it simple—no fancy layouts required.

The Best Companion Plants for Peppers
Group your companions by type, and you’ll keep things looking tidy (or at least less like a hot mess). Here’s how herbs, veggies, and flowers make your pepper plants happier, healthier, and more productive.
Herbs That Keep Peppers Happy
Herbs are the ultimate garden multitaskers—kind of like that family member who shows up, brings the good snacks, and scares off the cousins you don’t really want around. For peppers, these herbs step in as pest control, growth boosters, and flavor enhancers:
- Basil: Basil isn’t just for tomatoes. Plant some basil around your peppers to help keep aphids, thrips, and even mosquitoes away. It’s like a security blanket for your plants. You tuck basil in the outer corners of your pepper bed to avoid crowding.
- Oregano and Marjoram: Both sprawl a bit and make an aromatic barrier against garden pests. I’ll often snip off a few sprigs (for pizza night, of course) and let them fill in the gaps along the bed edge.
- Dill and Parsley: These attract helpful insects like ladybugs and lacewings (nature’s clean-up crew). I usually plant dill towards the back, since it gets tall but isn’t bossy about taking over.
- Cilantro and Chives: These guys won’t crowd out your peppers, and their strong scents can confuse or deter pests. Plant them in small pockets between pepper plants.
- Rosemary: Keep rosemary at the edges since it likes drier soil and can get bushy.
Tip: When planting these herbs, leave 8–10 inches between them and your peppers to avoid root competition (unless you want a “garden jungle,” which is sometimes my vibe by late summer, lol).
Veggies That Play Nice With Peppers
Not every veggie is a good match, but a few tried-and-true crops will help your pepper bed shine:
- Carrots: Sow carrots in rows along the front of your pepper bed. Their roots won’t compete with the deep roots of peppers, and they help aerate the soil.
- Onions and Garlic: Tuck these in at the ends or between rows. Their smell sends aphids and spider mites running. Plus, they don’t take up a ton of space.
- Leafy Greens (Spinach, Lettuce, Swiss Chard): Tuck spinach and lettuce around peppers to keep weeds down and the soil cool. I love me some baby spinach, and peppers cast just enough shade to help it along. Want even more ideas? Check out the best plants to grow with spinach—there’s a lot of overlap!
- Tomatoes: Peppers and tomatoes are natural friends, sharing similar growing conditions. Just give them extra room for airflow (learned that one the hard way).
- Radishes and Beets: Quick-growing, these root crops help mark rows, fill space, and break up compacted soil under peppers. You can plant them right in the row between your pepper plants.
- Beans and Peas (bush types): They fix nitrogen in the soil, which gives your peppers a little extra pep. Just don’t use pole beans, which can shade and smother your peppers.
Spacing Tip: Stagger your veggies so taller ones (like tomatoes and onions) are at the back or along the north edge, and your low growers (carrots, radishes) are in front. That way, everyone gets enough sun.
Flowers and More: Undercover Helpers
Flowers don’t just make your garden look pretty—they run pest patrol, pull in pollinators, and can help protect peppers from harsh wind or sun:
- Marigolds: There’s a reason you see these everywhere. Marigolds are like neon “do not enter” signs for nematodes and aphids. Tuck them around the bed’s perimeter.
- Nasturtiums: Not only are they edible (peppery flavor, yum), but nasturtiums draw away aphids better than almost anything. Let them trail over the bed edges.
- Calendula: Attracts pollinators and keeps soil cool with its sprawling habit.
- Borage: Brings in bees by the bucketful and deters tomato hornworms and cabbage worms.
Quick Tip: Pop these flowers at the corners or along the edges of your beds for maximum benefit without crowding out your peppers.
What NOT to Plant Near Peppers: The Plants That Clash
Just like people, pepper plants have some neighbors they’d rather avoid. Here’s the “nope” list:
- Fennel: This one is just a universal bad companion plant for almost any vegetable. It produces allelopathic chemicals that stuny growth or kill other veggies. Steer clear.
- Brassicas (Broccoli, Cabbage, Cauliflower, Kale): These are heavy feeders, so can take nutrients from your peppers. They also attract some of the same pests and prefer different growing conditions so they just don't match well with peppers.
- Pole Beans and Corn: These get too tall and cut off your peppers’ sun, turning the whole bed into a shady mess. Pole beans also vine and can choke out your pepper plants.
- Mint: Aggressive and will take over EVERYTHING, lol.
- Other heavy feeders: Keep other heavy feeders like squash and melons elsewhere. You don't want your veggies to compete for nutrients!
One year I wasn't thinking and planted cucumbers at the end of my pepper row. I put up a trellis for the cucumbers, but I also put tomato cages around my pepper plants. Well, guess what…. cucumber vines don't care which trellis they climb on.
The cucumbers, which are fast growing happily took over the pepper plant's cage and I had no peppers on that plant, lol. Lesson learned. That’s no big deal, though. If you garden, you will have plant combos that flop on ocassion.
Specific Pairings For Every Pepper: Hot, Jalapeno, and Bell
Not all peppers are the same. While they’re family, they like a slightly different crowd.
Best Companion Plants for Hot Peppers
Hot peppers (think habanero, cayenne, serrano) tend to be a little more pest-prone than sweet bells, so give them extra allies:
- Herbs: Basil, oregano, and cilantro do triple duty, driving off aphids and beetles while keeping soil loose around roots.
- Marigolds and Nasturtiums: These flowers are your hot peppers’ best defense line, especially if flea beetles or aphids love spicy food as much as you do.
- Garlic and Onions: Rise to the challenge with their strong scent barrier.
The Dream Team for Bell Peppers
Bell peppers like rich soil and lots of airflow. Try this combo:
- Leafy greens: Lettuce, spinach, and Swiss chard work as “living mulch,” keeping the bed cool and helping the soil retain moisture.
- Bush beans: Add a few along the row, but skip pole beans.
- Carrots, Radishes, and beets: Safe below-ground buddies.
- Layout idea: Make a U-shaped bed with peppers in the middle, leafy greens in the front, carrots and beets tucked on the sides, and flowers at the corners. Not fancy, just functional—but it still looks good by mid-season.
Beginner Tips for Successful Companion Planting with Peppers
So you’ve got your peppers and your wish list of plant pals—now what? Here’s how to keep the peace in your patch:
- Give Everyone Space: Most pepper varieties need about 18–24 inches between plants. Keep companions 8–12 inches away so roots don’t get tangled up in a custody battle.
- Rotate Beds Each Year: Don’t plant peppers in the same spot every season. This keeps pests and diseases guessing. (Don't put them in the same spot as tomatoes or other plants from the nightshade family either!)
- Water Deeply, Not Often: Soak the soil at the roots and keep the leaves dry if you can. Peppers don’t like soggy feet (honestly, who does?), but they enjoy a deep watering, then being allowed to dry out a bit. Deep watering also encourages the roots to grow down instead of out so they have access to water for longer.
- Watch for Pests: Aphids and spider mites love peppers. Knock them off with water or squish by hand (if you're braver than me), and let your herb and flower borders do most of the heavy lifting.
- Feed Moderately: Don’t overdo the fertilizer—too much nitrogen, and you’ll get bushy plants with fewer fruits.
