Companion Plants For Peppers- Both Hot and Sweet!

 

Peas: Peas are a great companion for peppers. Peas and peppers do not compete for nitrogen or other nutrients in the soil. Peas will actually fix nitrogen in the soil, making it more readily available for peppers.

Because peas are a cool weather crop and peppers prefer hot temperatures, it’s best to plant peas in the area first and then plant your pepper plants around them. The pea plants can be cut off above the soil after their season is over, making room for the peppers to take over the same space.

Basil: Basil is a great companion to many night shades. It is said to boost the flavor of your peppers.

Basil will also help repel some pests that are bothersome to peppers such as aphids, spider mites, and thrips.

Eggplant : Eggplant and peppers are in the same family so they have all of the same needs making them good companions. If you are growing nightshades in the same garden bed together be sure to rotate your beds from year to year to prevent more disease and pest problems.

Carrots: Carrots and peppers grow well together. The carrots add some weed control and also help create the humid growing conditions peppers like. The peppers also help keep the carrots sweet and give them shade!

Lettuce and Spinach: Lettuce and spinach make great companion plants for peppers because they don’t compete for the same nutrients. They also reduce weeds around your pepper plants. These greens are also mutually beneficial- giving more humidity to the peppers and receiving shade from the larger pepper plants.

Tomatoes: Again, because they are in the same crop family, tomatoes also make a great pepper companion plant. But do make sure your tomato plants don’t shade the pepper plants too much, so take care when planning your garden beds!

Pepper Companion Plants for Pest Control

French Marigolds: Marigolds show up in almost all companion planting lists, and for good reason. They are great at repelling squash bugs, soil nematodes,  potato bugs, and more. I recommend planting marigolds throughout your garden beds.

Parsley: Parsley is a great herb companion plant for your peppers. It will attract predatory wasps (and other beneficial insects) that help control aphids in your garden. Let the parsley flower for the biggest benefits.

Nasturtium: Nasturtium is another flower that lands on many companion planting lists. It’s benefits include deterring aphids, squash bugs, potato bugs, and whiteflies. Plus you can add the blossoms to your salads along with the peppers!

Garlic: Garlic is a great pest control companion for peppers. It can help with aphids, beetles, and spider mites.

Dill: Dill, like parsley, will attract pollinators and deter pests such as the spider mites that can destroy your pepper plants.

Geraniums: Geraniums are a great trap crop for Japanese beetles. The beetles will be paralyzed after eating the leaves of geraniums, giving you a chance to pick them off easily. Geraniums also repel cabbage worms.

If flea beetles are your problem, I suggest using diatomaceous earth to keep them in check. Dust your plants while they are small, up until they begin to flower. Once your peppers have flowered your pepper plants should be strong enough to fight flea beetle on their own.

 

 

What Not to Plant with Peppers

Beans (mostly hot peppers): Sweet and bell peppers don’t mind beans, but hot peppers especially should be kept away from all types of beans.

Fennel: Not much likes to grow near fennel, and peppers are no different. Keep this one in a separate bed.

All Brassicas: Peppers do not like being planted near brassicas. This includes broccoli, cauliflower, kale, brussels sprouts, and any others in this plant family.

Potatoes: Although peppers grow well with other nightshades, such as tomatoes and eggplant, they should be kept away from potatoes. This prevents the spread of disease in your garden. Also be sure to keep at least 2 years between planting pepper and potatoes in the same bed.
