Peas are a versatile and nutritious vegetable that can be grown in a variety of climates and conditions. They are a cool-season crop that can be planted in spring or fall, depending on your location. Peas thrive when grown alongside certain companion plants that provide support, attract beneficial insects, or enhance the soil. In this article, we will explore some of the best companion plants for peas and the benefits they bring.

1. Carrots

Carrots and peas make excellent companions in the garden. Carrots have long, slender roots that do not compete with the shallow root system of peas. Additionally, the two plants have different growth habits, with peas climbing on trellises or stakes and carrots growing underground. This allows them to make the most efficient use of space.

When grown together, carrots can help improve the soil for peas. Carrots are known for their ability to break up compacted soil, which benefits the shallow-rooted peas. The scent of carrots also helps repel pests that may be attracted to peas, such as aphids and nematodes.

2. Beans

Beans and peas are part of the same plant family, known as legumes. Legumes have a unique ability to fix nitrogen from the air and convert it into a form that plants can use. This makes them excellent companion plants, as they can provide a natural source of nitrogen for each other.

When peas and beans are grown together, they can create a mutually beneficial relationship. The peas can climb on the bean plants, using them as a trellis for support. In return, the beans provide nitrogen to the soil, which benefits the peas. This nitrogen-fixing ability also helps improve the overall fertility of the soil, benefiting other plants in the vicinity.

3. Radishes

Radishes are fast-growing root vegetables that can be planted alongside peas. Like carrots, radishes have long taproots that help break up compacted soil and improve drainage. This is particularly beneficial for peas, as they prefer well-drained soil.

Radishes also help deter pests that may be attracted to peas. Their strong scent can repel aphids and other insects that can damage the pea plants. Additionally, radishes can act as sacrificial crops, attracting pests away from the peas and diverting their attention.

4. Lettuce

Lettuce is a cool-season crop that can be planted alongside peas. The shallow root systems of both plants allow them to grow well together without competing for nutrients. Lettuce provides shade to the soil, helping to keep it cool and moist, which benefits the peas.

Additionally, lettuce can help deter pests that may be attracted to peas. The strong scent of lettuce can repel insects such as aphids and leaf miners. Planting lettuce in between rows of peas can create a barrier that pests have difficulty crossing.

5. Marigolds

Marigolds are often used as companion plants in vegetable gardens due to their ability to repel pests. They emit a strong scent that can deter insects such as aphids, nematodes, and beetles. Planting marigolds alongside peas can help protect them from these pests.

Marigolds also attract beneficial insects such as ladybugs and hoverflies, which feed on aphids and other pests. This can create a more balanced ecosystem in the garden, reducing the need for pesticides.


When planning your pea garden, consider planting them alongside compatible companion plants to maximize their growth and health. Carrots, beans, radishes, lettuce, and marigolds are excellent choices that provide various benefits such as improved soil fertility, pest deterrence, and support. Experiment with different combinations to find what works best for your garden. By using companion planting techniques, you can create a flourishing and harmonious garden that benefits all the plants involved.
