Planting peas with corn is a popular gardening technique that has been used for centuries. The practice of planting these two crops together is known as intercropping, and it has many benefits for both plants.

Peas and corn are complementary plants that work well together in the garden. Peas are legumes that are able to fix nitrogen from the air and convert it into a form that is usable by plants.

Corn, on the other hand, requires a lot of nitrogen to grow, making it the perfect companion for peas. When planted together, the peas provide the corn with the nitrogen it needs, while the corn provides the peas with support to climb and grow.

If you’re thinking about planting peas with corn, there are a few things to keep in mind.

First, it’s important to choose the right varieties of each plant. Some types of peas and corn are better suited for intercropping than others.

Additionally, you’ll need to make sure that the soil is well-drained and that the plants are getting enough water and sunlight.

With a little bit of planning and care, you can enjoy a bountiful harvest of peas and corn all summer long.

Understanding Companion Planting

As a gardener, I have learned that companion planting is a technique where different plant species are planted close to each other to help each other thrive. The benefits of companion planting are numerous. It can help improve soil health, provide natural pest control, and increase yields.

Benefits of Companion Planting

One of the main benefits of companion planting is nitrogen fixation. Some plants, like peas, beans, and clover, have the ability to take nitrogen from the air and convert it into a form that plants can use.

This process, known as nitrogen fixation, can help improve soil health and fertility.

Another benefit of companion planting is natural pest control. By planting certain companion plants, you can deter pests and attract beneficial insects.

For example, planting marigolds alongside tomatoes can help deter nematodes, while planting dill and parsley can attract beneficial insects like ladybugs and lacewings.

Companion Planting Chart

To get the most out of companion planting, it’s important to have a companion planting chart. This chart will help you determine which plants grow well together and which ones should be kept apart.

Some good companion plants for peas include beets, turnips, lettuce, kale, spinach, sweet alyssum, carrots, and corn.

On the other hand, it is best to avoid planting peas alongside onions, garlic, and peppers, as they can negatively affect their growth.

The Three Sisters Technique

One of the most popular companion planting techniques is the Three Sisters technique. This technique involves planting corn, beans, and squash together.

The corn provides a structure for the beans to climb, while the beans provide nitrogen for the corn and squash.

The squash, in turn, provides a ground cover that helps retain moisture and suppress weeds.

Companion Plants for Peas

In addition to the plants mentioned in the companion planting chart, there are other plants that make good companions for peas. These include cucumber, beans, potatoes, and radish.

Companion Plants for Corn

Corn also has its own set of companion plants. These include cucumber, beans, potatoes, and squash.

Planting these plants alongside corn can help improve soil health and provide natural pest control.

Preparing the Soil for Planting

As I prepare to plant peas with corn, I understand the importance of preparing the soil properly. A well-prepared soil ensures that the plants get the required nutrients, water, and air for healthy growth.

Soil Requirements for Peas and Corn

Peas and corn require well-draining soil that is rich in nutrients. The soil should have a pH range of 5.8 to 7.0, slightly acidic to neutral.

According to, it is a good idea to have the soil tested every few years to keep the pH level balanced. This ensures that fertilizers will be more efficient and symbiotic nitrogen-fixing bacteria will thrive.

To ensure proper drainage, I will not plant pea seeds in wet areas where the soil doesn’t drain well, as the seeds may end up rotting before they get a chance to germinate.

If necessary, I can raise the beds up to six or eight inches high to provide a well-draining site for my peas.

I will also turn over the beds while adding two to three inches of compost or aged manure, as recommended by Gardening Channel. This will help improve the soil’s structure, texture, and water-holding capacity.

Fertilizing Before Planting

Before planting, I will fertilize the soil to provide the necessary nutrients for the plants.

Peas and corn require different nutrients for optimal growth. While peas require more nitrogen, corn requires more phosphorus and potassium.

According to SipsScene, planting peas with corn creates a beneficial partnership as peas enrich the soil with nitrogen, while corn helps aerate the soil and improve drainage.

To fertilize the soil, I will use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium.

Alternatively, I can use a fertilizer with higher nitrogen content, such as 10-10-10 or 20-10-10, to meet the nitrogen requirements of peas.

I will apply the fertilizer evenly over the soil, following the manufacturer’s instructions. Once I have fertilized the soil, I will rake it to ensure that the fertilizer is mixed evenly with the soil.

Planting Techniques

When planting peas with corn, there are certain techniques that can help ensure a successful harvest. Here are some tips to consider:

Sowing Peas and Corn Together

When sowing peas and corn together, it’s important to keep in mind that corn grows much faster than peas.

Therefore, it’s best to plant the peas first and then add the corn a few weeks later. This will allow the peas to get established before the corn overshadows them.

Plant peas and corn in early spring when the soil has warmed up and there’s no danger of frost. Choose a location that receives full sun and has well-drained soil.

Spacing and Support for Peas

When planting peas, you have two options: pole beans or bush peas.

Pole beans require support, while bush peas do not. If you choose to plant pole beans, make sure to provide them with a sturdy support structure. You can use a trellis, stakes, or a fence.

For bush peas, plant the seeds 1 inch deep and 1 inch apart in rows that are 2 feet apart. Thin the successful plants to 4 inches apart in all directions.

When planting corn, space the seeds 8-10 inches apart in double rows on either side of 6-foot tall stakes. This will provide support for the peas as they grow.

Watering and Mulching

Peas and corn both require regular watering to thrive.

Water deeply once a week, making sure to keep the soil evenly moist. Mulching around the plants can help retain moisture and suppress weeds.

Pest Management

Pest Management plants peas alongside corn in a field

As with any garden, pest management is crucial to ensure a healthy and productive crop. When planting peas and corn together, it is important to be aware of the common pests that can affect both plants.

Common Pests for Peas and Corn

Aphids, ants, thrips, and flea beetles are all common pests that can affect both peas and corn.

Mexican bean beetles are also a concern for peas. These pests can cause damage to the plants, reducing yield and overall health.

Natural Pest Control Methods

One effective method of pest control is to introduce beneficial insects to the garden.

Hoverflies, lacewings, parasitic wasps, and ladybugs are all beneficial insects that can help control pest populations. These insects prey on pests such as aphids and thrips, reducing their numbers and preventing damage to the plants.

Another natural method of pest control is to plant companion plants that repel pests.

For example, marigolds and nasturtiums are known to repel aphids and other pests. Planting these flowers alongside your peas and corn can help keep pests at bay.

It is also important to practice good garden hygiene to prevent pest infestations.

Removing dead plant material and weeds can help reduce hiding places for pests. Additionally, rotating crops can help prevent the buildup of pest populations in the soil.

Harvesting and Storage

When to Harvest Peas and Corn

When growing peas with corn, it is important to harvest them at the right time to ensure maximum flavor and quality.

Peas should be harvested when the pods are plump and firm, but before they start to yellow and dry out. This is usually around 60-70 days after planting, depending on the variety.

Sweet corn, on the other hand, should be harvested when the kernels are fully formed and the ears are still tender. This is usually around 20-25 days after the silks appear.

Edible pod peas, also known as snow peas or sugar snap peas, can be harvested when the pods are flat and the peas inside are just beginning to form. This is usually around 55-65 days after planting.

Storing Peas and Corn

To keep your peas and corn fresh and flavorful, it is important to store them properly.

Peas should be stored in a cool, dry place, away from direct sunlight. They can be stored in the refrigerator for up to a week, or frozen for longer-term storage.

To freeze peas, simply blanch them in boiling water for 1-2 minutes, then plunge them into ice water to stop the cooking process. Drain well and pack into freezer bags or containers.

Corn should be stored in the refrigerator and used within a few days of harvesting for best flavor and texture.

If you need to store corn for longer, you can freeze it by blanching the ears in boiling water for 4-6 minutes, then cooling in ice water and removing the kernels from the cob.

The kernels can then be packed into freezer bags or containers and stored for up to 8 months.

Crop Rotation and Sustainability

Importance of Crop Rotation

Crop rotation is a technique that involves planting different crops in the same area over time to maintain soil health, prevent soil-borne diseases, and improve yields.

This practice is essential in sustainable agriculture as it helps to reduce the reliance on synthetic fertilizers and pesticides, which can be harmful to the environment.

In particular, planting peas with corn is a great example of crop rotation. Peas are legumes that fix nitrogen from the air into the soil, which is beneficial to corn, a crop that requires a lot of nitrogen to grow.

This process ensures that the soil remains fertile and healthy, reducing the need for synthetic fertilizers.

Moreover, crop rotation helps to prevent soil erosion, which is a significant environmental issue.

By rotating crops, the soil structure is maintained, and soil erosion is reduced, which ensures that the soil remains healthy and productive.

Sustainable Practices in the Home Garden

As a home gardener, there are several sustainable practices that you can adopt to ensure that your garden remains productive and healthy.

One of the most important practices is crop rotation. By rotating crops, you can maintain soil health, prevent soil-borne diseases, and improve yields.

In addition to crop rotation, you can also use organic fertilizers, such as compost and manure, to improve soil fertility.

These fertilizers are rich in nutrients and help to improve soil structure, which is essential for plant growth.

Another sustainable practice is intercropping, which involves planting different crops together in the same area.

This practice helps to reduce pest and disease problems, improve soil health, and increase yields.

Varieties and Selection

When it comes to planting peas with corn, selecting the right varieties is crucial for a successful harvest. In this section, I will cover the key factors to consider when choosing pea and corn varieties.

Choosing Pea Varieties

Peas come in several varieties, including garden peas, snow peas, snap peas, and shelling peas.

Garden peas, also known as English peas, are the most commonly grown variety and are perfect for planting with corn. Some of the popular garden pea varieties include Green Arrow and Lincoln.

When selecting pea varieties, it is important to consider the time to maturity, disease resistance, and yield potential.

Green Arrow is a popular variety that matures in 68-70 days and has a high yield potential. Lincoln, on the other hand, matures in 75-80 days and is known for its disease resistance.

Selecting Corn Varieties

Sweet corn is the best type of corn to plant with peas. When selecting corn varieties, it is important to consider the time to maturity, sweetness, and yield potential.

Some of the popular sweet corn varieties include Golden Bantam, Ambrosia, and Honey Select.

Golden Bantam is a popular variety that matures in 75-80 days and has a sweet, rich flavor. Ambrosia is another popular variety that matures in 75-80 days and has a high yield potential.

Honey Select is a newer variety that matures in 75-80 days and is known for its exceptional sweetness.

Additional Companion Plants

When planting peas with corn, there are other companion plants that can help improve the health and yield of your crops. These companion plants can help attract beneficial insects, repel pests, and improve soil health.

Vegetable Companions

Plants like carrots, cucumbers, lettuce, radishes, and spinach are great vegetable companions for peas and corn.

These plants have shallow roots that won’t compete with the deeper roots of corn and peas. Additionally, they can help improve soil health by adding nutrients and organic matter to the soil.

Herb and Flower Companions

Herbs and flowers can also make great companions for peas and corn.

Basil, dill, marigolds, nasturtiums, and chives can all help repel pests and attract beneficial insects.

Garlic and onions are also great for repelling pests, but should be planted away from peas and corn as they can stunt their growth.

Mint and alyssum are also great companion plants for peas and corn.

Mint can help repel pests and improve soil health, while alyssum attracts beneficial insects like bees and butterflies.

Avoiding Incompatible Plants

While there are many plants that make great companions for peas and corn, there are also some plants that should be avoided.

Pole types of peas and corn should not be planted together as they can compete for space and resources. Leeks, onions, garlic, and chives should also be planted away from peas and corn as they can stunt their growth.
