Companion Plants for Peas


Peas are a popular vegetable, loved for their sweet and crisp taste. Growing peas in your garden is not only rewarding, but it can also be beneficial to plant them alongside certain companion plants. Companion planting is a gardening technique where different plants are grown together to maximize their growth, deter pests, and improve overall garden health. In this article, we will explore some of the best companion plants for peas in 2023.

Why Companion Plants?

Companion plants can offer numerous benefits to pea plants. Some companion plants help improve the soil quality by fixing nitrogen, which is essential for pea growth. Other companion plants attract beneficial insects, such as pollinators and pest predators, which can help control common pests that affect peas. Additionally, certain plants can provide shade or act as a trellis for the climbing varieties of peas. Overall, companion plants can enhance the health and productivity of your pea plants.

Best Companion Plants for Peas

1. Beans

Beans and peas are part of the same plant family, making them excellent companions. Beans fix nitrogen in the soil, which benefits peas that have high nitrogen requirements. Planting beans and peas together can lead to healthier plants and increased yields.

2. Carrots

Carrots and peas make great companions as they have complementary root systems. Carrots have long, slender roots that help break up the soil, making it easier for peas to grow their shallow roots. Additionally, peas provide shade to carrots, helping to keep the soil cool and moist.

3. Radishes

Radishes are known for their ability to repel pests such as aphids and cucumber beetles. By interplanting radishes with peas, you can help protect your pea plants from these common pests. Radishes also help improve soil aeration and nutrient availability.

4. Marigolds

Marigolds are often used as companion plants in vegetable gardens due to their strong scent, which deters many pests. Planting marigolds alongside peas can help keep pests like aphids, nematodes, and bean beetles at bay. Marigolds also attract beneficial insects like ladybugs, which feed on aphids and other harmful pests.

5. Nasturtiums

Nasturtiums are excellent companion plants for peas as they attract beneficial insects like bees and hoverflies, which are important pollinators. These insects help ensure proper pea pollination, leading to higher yields. Nasturtiums also act as a sacrificial plant, attracting pests away from peas.

6. Corn

Planting corn alongside peas can provide a natural trellis for the climbing varieties of peas. The cornstalks act as support for the pea vines, reducing the need for additional trellising. Additionally, corn provides shade to the peas, helping to keep the soil cool and moist.

7. Lettuce

Lettuce is a great companion plant for peas as it provides shade to the shallow-rooted pea plants, helping to keep the soil cool and moist. Lettuce also helps suppress weed growth around pea plants, reducing competition for nutrients and water.

8. Chives

Chives are known to repel pests such as aphids and Japanese beetles. Planting chives alongside peas can help protect the pea plants from these pests. Additionally, chives attract beneficial insects like bees and butterflies, which aid in pollination.

9. Sunflowers

Sunflowers are tall and sturdy plants that can provide shade and support for the climbing varieties of peas. The sunflower stalks act as natural trellises, reducing the need for additional support. Sunflowers also attract beneficial insects and birds, which can help control pests in the garden.


When planning your pea garden, consider incorporating companion plants to maximize the health and productivity of your peas. Companion plants such as beans, carrots, radishes, marigolds, nasturtiums, corn, lettuce, chives, and sunflowers can offer numerous benefits, from fixing nitrogen in the soil to repelling pests and attracting beneficial insects. Experiment with different companion plants and enjoy a bountiful harvest of delicious peas.
