Companion Plant for Peas: Boosting Growth and Yield

As a gardener, I am always looking for ways to improve my yield and protect my plants from pests and diseases. One of the most effective methods I have found is companion planting. Companion planting involves growing different plants together that benefit each other in some way. When it comes to peas, companion planting can be especially beneficial.

There are many benefits of companion planting for peas. For one, certain plants can help deter pests that commonly attack peas, such as aphids and pea weevils. Additionally, some plants can help improve the soil quality and provide necessary nutrients for peas to thrive. By strategically planting companion plants around your peas, you can create a healthier and more productive garden.

Key Takeaways

  • Companion planting can be an effective way to protect peas from pests and improve soil quality.
  • Some of the best companion plants for peas include beans, carrots, and radishes.
  • To implement companion planting in your garden, consider the needs of your peas and choose companion plants that will provide the most benefit.

Benefits of Companion Planting for Peas

As a gardener, I have found that companion planting is an effective way to improve the health and yield of my pea plants. Here are some benefits of companion planting for peas:

  1. Pest Control: Peas are often attacked by pests such as aphids and bean beetles. However, planting certain companion plants like marigolds, mint, and chives can help deter these pests and protect your pea plants.
  2. Nutrient Fixation: Peas are legumes and have the ability to fix nitrogen in the soil. However, they require a lot of nitrogen to grow. By planting companion plants like clover or alfalfa, which also fix nitrogen, you can help improve the soil quality and provide the necessary nutrients for your pea plants.
  3. Improved Soil Structure: Some companion plants like radishes and carrots have long taproots that help break up compacted soil. This can improve soil aeration and drainage, which is beneficial for the growth of your pea plants.
  4. Attracting Beneficial Insects: Planting companion plants like lavender, dill, and yarrow can attract beneficial insects like ladybugs and lacewings, which can help control pests that may harm your pea plants.

In conclusion, companion planting is a great way to improve the health and yield of your pea plants. By carefully selecting and planting companion plants, you can create a more diverse and balanced ecosystem in your garden, which can lead to healthier and more productive pea plants.

Best Companion Plant for Peas

As a gardener, I know that companion planting can be a great way to improve the health and yield of my pea plants. Here are some of the best companion plants for peas that I have found to be effective:


Peas are legumes themselves, so it makes sense that they would do well when planted with other legumes. Beans, for example, can help fix nitrogen in the soil, which can benefit the growth of peas. Additionally, peas and beans have similar soil and water requirements, making them a great match.


While peas and brassicas (such as broccoli and cauliflower) may seem like an odd pairing, they can actually benefit each other. Peas can help to repel pests that may attack brassicas, while the brassicas can provide shade for the peas during hot summer months.

Leafy Greens

Leafy greens like lettuce and spinach make great companions for peas. These plants have shallow roots, which means they won’t compete with the deeper roots of the peas. Additionally, the peas can provide shade for the leafy greens, helping to keep them cool during hot weather.


Herbs like mint and basil can help to repel pests that may attack pea plants. Additionally, these herbs can add flavor to your peas when harvested together. Just be sure to plant your herbs in a separate container or area of the garden, as they can quickly take over and compete with your pea plants.

By planting these companion plants alongside your peas, you can help to improve the health and yield of your pea plants. Remember to always do your research and experiment with different combinations to find what works best for your garden.

Companion Planting Strategies

Peas grow alongside nitrogen-fixing plants like beans and clover, while repelling pests with aromatic herbs like mint and chamomile

Spatial Arrangement

When it comes to companion planting for peas, spatial arrangement is an important consideration. Peas are climbers, so it’s best to plant them next to taller plants that can provide support. Good choices for companion plants include corn, sunflowers, and pole beans. These plants can also help to provide shade for the peas during the hottest part of the day.

Timing and Succession

Timing is another important factor to consider when companion planting for peas. Peas are a cool-season crop, so it’s best to plant them in early spring or late summer. If you’re planting in the spring, try to get your peas in the ground as soon as the soil can be worked. For a fall crop, plant your peas about 8-10 weeks before the first expected frost.

Succession planting is also a good strategy for maximizing your pea harvest. Plant a new batch of peas every 2-3 weeks, starting in early spring and continuing through mid-summer. This will ensure a steady supply of fresh peas throughout the growing season.

Companion Planting for Pest Control

Companion planting can also be used to help control pests that can damage your pea plants. One effective strategy is to plant marigolds or other strong-smelling plants around the perimeter of your garden. These plants can help to repel pests like aphids and whiteflies.

Another effective companion plant for peas is mint. Mint has a strong scent that can help to repel pests like ants and flea beetles. Be careful when planting mint, however, as it can be invasive and take over your garden if not properly contained.

By using these companion planting strategies, you can help to ensure a healthy and productive pea crop.

Plants to Avoid Near Peas

As a gardener, I have learned that not all plants make good companions for peas. Some plants can attract pests or compete for nutrients, leading to stunted growth or reduced yields. Here are some plants I avoid planting near my peas:

  • Onions and Garlic: While onions and garlic can repel some pests, they can also stunt the growth of peas if planted too close. They both belong to the Allium family, which can release chemicals that inhibit the growth of other plants.
  • Beans and Peppers: Peas and beans are both legumes, and planting them together can lead to nitrogen depletion in the soil. Peppers can also attract aphids, which can spread to peas and cause damage.
  • Brassicas: Members of the Brassica family, such as broccoli and cabbage, can attract pests like aphids and cabbage worms, which can damage peas and reduce yields.
  • Fennel: Fennel can attract beneficial insects, but it can also release chemicals that inhibit the growth of peas and other plants.

To avoid these problems, I make sure to plant my peas away from these plants and instead choose companions that can benefit them, such as carrots, lettuce, and spinach. By being selective about my planting choices, I can help my peas thrive and produce a bountiful harvest.

Implementing Companion Planting in Your Garden

As a gardener, I have found that companion planting can be a valuable tool for growing healthy and productive pea plants. By planting certain plants together, you can help deter pests, improve soil quality, and even increase yields. Here are a few tips for implementing companion planting in your garden:

  1. Choose the right companions: When selecting companion plants for peas, look for plants that have similar soil and water requirements, as well as those that can help repel pests and attract beneficial insects. Some good companion plants for peas include carrots, radishes, and beans.
  2. Plan your layout: Consider the layout of your garden when implementing companion planting. For example, you may want to plant taller plants such as beans or corn on the north side of your pea plants to provide shade during the hottest part of the day.
  3. Rotate your crops: To prevent soil-borne diseases and pests, it’s important to rotate your crops each year. This means planting your peas in a different location each season, and avoiding planting them in the same spot for at least three years.
  4. Use natural pest control methods: Companion planting can help deter pests, but it’s also important to use natural pest control methods such as handpicking, using insecticidal soap, and introducing beneficial insects like ladybugs and lacewings.

By implementing companion planting in your garden, you can create a healthy and productive environment for your pea plants. With a little planning and care, you can enjoy a bountiful harvest of delicious and nutritious peas.

Monitoring and Maintaining a Companion Planted Garden

As a gardener, it is important to monitor and maintain the health of your companion planted garden. Here are some tips to help you keep your garden thriving:

Regular Inspection

Regularly inspect your plants for any signs of pests or diseases. Early detection is key to preventing the spread of these issues. Look for any discoloration, wilting, or unusual growth patterns in your plants.

Proper Watering

Proper watering is essential for the health of your plants. Be sure to water your plants deeply and consistently, but avoid overwatering, as this can lead to root rot. Use a watering can or hose to water at the base of the plant, rather than the leaves.

Organic Pest Control

Using organic pest control methods is a great way to keep your garden healthy without the use of harmful chemicals. Companion planting is one way to naturally repel pests. For example, planting marigolds alongside your peas can help deter pests such as aphids.

Crop Rotation

Crop rotation is another important aspect of maintaining a healthy garden. This involves planting different crops in different areas of your garden each year to prevent the buildup of pests and diseases. Try to rotate your peas with plants from a different family, such as beans or corn.

By following these tips, you can ensure that your companion planted garden remains healthy and productive.
