Pepper plants are a staple in many gardens, providing vibrant colors and a delicious, versatile addition to our meals.
As much as we love to grow these fiery delights, it’s crucial to be aware of the plants that might not play well with our precious peppers.
In this article, we’ll take a look at 13 plants that could potentially cause harm to your peppers, so you can avoid making any “garden faux pas.”
Buckle up, green thumbs, and let’s dig into the dirt!
1. Potatoes
Potatoes and peppers may both be part of the nightshade family, but they’re like distant cousins who bicker at family reunions.
Growing them together can encourage the spread of pests and diseases, particularly blight.
So keep the spuds and peppers apart, or you might end up with some sad-looking plants.
Additionally, potatoes require a different watering schedule than peppers, so planting them together might make it tricky to keep both sets of plants happy and healthy.
2. Fennel
Fennel may look lovely and delicate, but it’s a bit of a garden diva.
It doesn’t get along with many plants, and peppers are no exception.
Fennel exudes a substance that inhibits the growth of surrounding plants, so it’s best to give fennel its own personal stage, far away from your peppers.
This way, your peppers can thrive without being stifled by fennel’s overbearing presence.
3. Cabbage
Cabbage might be a staple in your coleslaw, but it doesn’t belong near your peppers.
Cabbage attracts several pests like cabbage worms, flea beetles, and cutworms.
These little munchers might decide your peppers are a tasty alternative to cabbage, so it’s best to keep them separated in the garden.
Plus, cabbage plants can cast shade on your sun-loving peppers, potentially stunting their growth.
4. Broccoli
Broccoli, like cabbage, attracts pests that can damage your peppers.
Plus, broccoli is a heavy feeder, meaning it gobbles up a lot of nutrients from the soil.
If grown together, these nutrient-hungry plants can lead to a lackluster harvest.
Better to keep them apart and let them hog the soil nutrients separately.
Your peppers will thank you for it.
5. Cauliflower
Cauliflower is just another troublemaker from the Brassica family, and it’s best not to let it hang out with your peppers.
It competes with peppers for valuable nutrients and can even block sunlight, which is essential for pepper growth.
To top it all off, cauliflower also attracts the same pests that cabbage does.
It’s best to keep this veggie at a safe distance from your peppers, so both can flourish.
6. Kohlrabi
Kohlrabi is yet another Brassica family member that doesn’t play well with peppers.
It competes for nutrients and space, which can stunt pepper growth.
Also, like its other Brassica cousins, kohlrabi attracts pests that may decide to snack on your peppers.
So, save your peppers some grief and give kohlrabi its own plot in the garden.
7. Brussels Sprouts
Brussels sprouts, the mini cabbage lookalikes, share similar issues with other Brassica plants when planted near peppers.
They compete for nutrients, can block sunlight, and attract pests that can harm your pepper plants.
Keep them apart in the garden, and they’ll both be happier for it.
8. Collard Greens
Collard greens may be a southern favorite, but they’re not the best neighbors for your pepper plants.
Like their Brassica relatives, collard greens can steal nutrients and attract pests that could potentially harm your peppers.
Give collard greens their own space, away from your precious peppers, and enjoy a bountiful harvest of both.
9. Turnips
Turnips, another member of the Brassica family, continue the trend of causing problems for pepper plants.
They compete for nutrients and water, and also bring along their own set of pests that could munch on your peppers.
To ensure a healthy pepper harvest, plant turnips in a separate area of the garden.
10. Mustard Greens
Mustard greens are known for their spicy kick, but when it comes to being neighbors with peppers, they just don’t get along.
Being part of the Brassica family, mustard greens share similar issues with their cousins, attracting pests and competing for resources.
Keep these fiery greens away from your peppers for optimal growth.
11. Radicchio
Radicchio, while not part of the Brassica family, can still cause trouble for your peppers.
This leafy vegetable is a heavy feeder and competes for nutrients in the soil.
If planted too close to your peppers, radicchio can limit the nutrients available to them, resulting in less-than-ideal growth.
So, give radicchio its own space to thrive, away from your pepper plants.
12. Mint
Mint may smell delightful and taste great in your iced tea, but it’s not the friendliest companion for peppers.
Mint is a notorious spreader, and its roots can quickly invade the space and resources of nearby plants, including peppers.
It’s best to keep mint contained in a pot, far away from your peppers, to prevent it from taking over your garden.
13. Walnut Trees
While not a plant you would typically find in your vegetable garden, it’s essential to know that walnut trees can negatively affect pepper growth.
Walnut trees produce a substance called juglone, which is toxic to many plants, including peppers.
If you’re growing peppers near a walnut tree, you might find your plants struggling to survive.
So, make sure to plant your peppers a safe distance from any walnut trees to ensure their health and vitality.
Final Thoughts
Just like people, plants have their own preferences when it comes to companions.
Knowing which plants to avoid planting near your peppers can save you from a disappointing harvest and potential garden heartbreak.
By keeping these 13 damaging plants away from your peppers, you’ll set the stage for a bountiful and successful pepper harvest.
Happy gardening!
