In this article, we’re answering the question: How much space do peas need to grow?

We’ll also give you some helpful tips to get the most out of growing peas.

Let’s get started.

How Much Space Do Peas Need to Grow?

Plant Spacing

Proper plant spacing is crucial for growing peas as they require adequate room to grow and get enough sunlight. Generally, it’s recommended to plant peas 1 to 2 inches apart, and later thin them to be 3 inches apart. This spacing ensures that each pea plant can access the necessary light, air, and nutrients for healthy growth. The depth of planting should not exceed 1.5 inches, as pea plants need more exposure to sunlight and warm temperatures than many other plants(source).

Row Spacing

Row spacing for pea plants depends on the variety and the type of support system you’re using for the plants. In general, rows can be spaced as close as 12 to 18 inches apart. However, taller varieties and their trellises are easier to harvest and care for if the row spacing is doubled to 24-36 inches(source). This wider spacing accommodates the additional height and makes it easier to tend to, harvest, and navigate through the pea patch.

To simplify the spacing process, consider using the following guidelines:

  • Short varieties: 12 to 18 inches row spacing
  • Tall varieties with trellises: 24 to 36 inches row spacing

Remember that providing the right amount of space for your pea plants will encourage healthy growth, making your garden more productive and easier to care for.

Spacing Peas in Different Growing Spaces

In Ground Planting

When planting peas in the ground, the spacing varies slightly depending on the type of pea plant. For bush varieties, seeds should be planted about 1-2 inches (2.5-5cm) apart, whereas climbing varieties need slightly larger spacing, about 2-3 inches (5-7.5cm) apart (source).

Regarding row spacing, it’s advised to maintain a 12-18-inch gap between the rows (source). This ensures that each plant has ample room to grow, preventing disease and competition for resources.

Raised Beds

For raised beds, the planting and row spacing remain similar to in-ground planting. The most significant difference is the depth of the raised bed. The bed should be at least 2 feet deep to accommodate the roots of the pea plants (source).

It’s essential to maintain proper spacing in raised beds, as it allows for better air circulation, reducing the risk of disease and ensuring that the plants have enough room to grow and access nutrients from the soil.

Container Gardening

When growing peas in containers, the spacing depends on the container’s size and the pea variety. Generally, you can follow the spacing guidelines for in-ground planting. However, consider the container’s diameter and depth to ensure that the peas have enough room to grow.

In a typical container, plant seeds 1.5-3 inches apart and use a pot that is at least 12 inches deep (source).

Here are some tips for container gardening with peas:

  • Choose a container with drainage holes to avoid waterlogging.
  • Use high-quality potting soil to provide adequate nutrients.
  • Ensure the container receives sufficient sunlight for healthy growth.

Pea Spacing Mistakes

One common mistake gardeners make is planting pea seeds too close together. While peas might seem small and compact, they require adequate space to grow without competing for resources with their neighbors. Recommended spacing for peas is 2-3 inches apart and row spacing of 12-18 inches

Another error often made involves planting pea seeds too deep or too shallow in the soil. Ideally, pea seeds should be planted about 1.5 inches deep and at least 1 inch apart. Planting them deeper can make it harder for the seeds to sprout, while planting them too shallow might expose them to harsh environmental conditions and pests.

Ignoring the need for proper support structures for taller pea varieties is another oversight some gardeners face. Depending on the type, some peas will require support from trellises to climb and grow properly. Make sure you provide these structures to ensure healthy plant development and better yield.

Lastly, it’s crucial to avoid overcrowding your peas in raised beds. According to Green Upside, a raised garden bed should be at least 2 feet deep to accommodate the roots of the pea plants. The proper depth ensures that the plants’ roots have enough room to grow, supporting overall plant health and yield.

Spacing for Different Varieties of Peas

When planting peas, it’s essential to consider the variety, as different types have specific spacing requirements to grow and thrive. This section will discuss the spacing guidelines for various pea varieties.

Bush peas, also known as dwarf varieties, can be planted with closer spacing. These compact plants require about 1-2 inches (2.5-5 cm) apart within the row. In contrast, climbing peas or vining varieties need slightly more space, with an ideal spacing of 2-3 inches (5-7.5 cm) apart in the row.

Row spacing is equally important, as it allows for adequate light, airflow, and room for growth. Generally, rows should be spaced 12-18 inches apart for both bush and climbing pea varieties. However, tall-growing peas should be planted in double rows, with each row spaced 4-6 inches apart and 2.5 feet between the double rows, as recommended by Seeds Now.

To help you visualize the proper spacing for different pea varieties, here’s a summary:

  • Bush peas: 1-2 inches (2.5-5 cm) apart within the row; 12-18 inches between rows
  • Climbing peas: 2-3 inches (5-7.5 cm) apart within the row; 12-18 inches between rows
  • Tall-growing peas (double rows): 4-6 inches apart within the row; 2.5 feet between double rows

When planning your pea garden, always consider the specific requirements of the variety you choose to ensure optimal growth and yield.

Tips for Growing Peas

Peas are a popular and easy-to-grow vegetable in many gardens. To ensure a successful crop, consider the following tips:

1. Planting Time: Peas prefer cool weather, so it’s best to plant them early in the spring, as soon as the soil can be worked. In some regions, planting a fall crop is also possible. Just make sure to give the plants enough time to mature before the first frost.

2. Soil Preparation: Peas will thrive in well-drained, fertile soil with a pH level between 6.0 and 7.0. Adding organic matter, such as compost or well-rotted manure, can improve soil structure and provide essential nutrients for healthy plant growth.

3. Seed Spacing: Pea seeds should be planted about 1.5 inches deep and a minimum of 1 inch apart, to allow for adequate growth and less risk of disease and competition. Wider spacings can be used for bush-type peas, while more compact varieties may be planted closer together. Some sources suggest planting rows 7 inches apart or using double rows with a 30 to 36-inch spacing for tall pea varieties.

4. Proper Support: Providing support, such as a trellis, for taller pea varieties is essential for their growth. Installing a trellis or some other form of support at planting time is recommended. A common row spacing for trellised peas is 4-6 feet.

5. Regular Watering: Peas need consistent moisture during their growing season, so it’s important to water the plants regularly. Water the soil around the plants, avoiding wetting the foliage to prevent the spread of diseases.

6. Crop Rotation: To prevent the buildup of diseases in the soil, do not plant peas in the same location more than once every four years. Rotating your pea plants with other crops can help keep the soil healthy and improve disease resistance.

7. Pest Control: Keep an eye out for common pea pests, such as aphids and pea weevils, and take action to control them if necessary. This may include using insecticidal soaps, introducing beneficial insects, or employing other organic pest control methods.
