With the right tips and techniques, however, you can enjoy a bountiful harvest of fresh, tender peas that are perfect for salads, soups, and other tasty dishes. In this article, we’ll delve into the nuances of growing peas in Colorado, covering the specific climate conditions, pea varieties, soil preparation, planting and maintenance tips, and harvesting techniques. Let’s get started!

Understanding the Colorado Climate for Pea Cultivation

Colorado’s climate can pose some challenges when it comes to growing peas. However, with a good understanding of the specific conditions needed for pea cultivation in this region, gardeners can achieve a bountiful harvest.

Ideal Temperature Range

Peas prefer cooler temperatures for optimal growth and development. In Colorado, it is best to plant peas in the early spring when the average temperature is between 40-75°F. Peas do not tolerate heat well, so it is important to avoid planting them when temperatures exceed 80°F.

Sun Exposure

Peas require at least 6 hours of direct sunlight per day, but in Colorado, excessive sun exposure during the heat of the day can cause the plants to wilt and stunt their growth. It is best to provide some shade during the hottest part of the day to protect the plants.

Moisture Requirements

Peas require consistent moisture to grow well, but overwatering can lead to root rot. In Colorado, it is important to monitor soil moisture levels closely, especially during the hot and dry summer months. It is best to water deeply and infrequently, allowing the soil to dry out slightly between watering sessions.

Selecting the Best Pea Varieties for Colorado

When deciding which pea variety to plant in Colorado, it’s important to choose options that are well-suited to the unique climate and growing conditions. The right pea variety can make all the difference in having a bountiful harvest. Here are a few top picks for peas that thrive in Colorado:

Pea Variety Characteristics
Green Arrow Early maturation and high yield
Wando Cold tolerance and disease resistance
Little Marvel Disease resistance and sweet flavor

These varieties all have unique benefits that make them ideal for growing peas in Colorado. However, there are many other options to choose from depending on personal preferences and specific growing conditions. Be sure to do research and talk to local gardening experts to find the best pea variety for your specific needs.

Preparing the Soil for Pea Planting

Before planting your pea seeds, it is important to prepare the soil to ensure optimal growth and productivity. Here are some tips to get your soil ready for planting:

Step Description
1 Test your soil: Conduct a soil test to determine the nutrient levels and pH balance of your soil. Based on the results, add soil amendments like compost, manure or lime to adjust the soil pH or nutrient content for optimal pea growth.
2 Loosen the soil: Peas grow best in well-draining soil that is loose and friable. Use a garden fork or tiller to loosen the soil to a depth of at least 12 inches.
3 Add organic matter: Adding organic matter like compost, leaves or grass clippings to the soil improves its texture and adds essential nutrients to the soil.
4 Break up clumps: Remove any large clumps or rocks that may impede root growth or inhibit water penetration.

By taking these steps to prepare your soil, you are setting the foundation for healthy and vigorous pea growth, leading to a bountiful harvest.

Planting Peas in Colorado

Now that you’ve prepped your soil, it’s time to start planting your peas! Follow these simple steps for a successful pea crop.

  1. Choose the right time: Peas prefer cooler temperatures, so aim to plant in early spring or late summer. In Colorado, this means planting in mid-March to early April for a spring crop, or in late August for a fall crop.
  2. Prepare your seeds: Soak pea seeds overnight before planting to speed up germination. This will help the seeds absorb water and begin the germination process more quickly.
  3. Plant your seeds: Plant your seeds about 1 inch deep and 2-3 inches apart. If planting in rows, space rows about 2 feet apart to allow for adequate growth.
  4. Water your seeds: After planting, water your seeds well. Peas need consistent moisture to germinate, so keep the soil moist but not waterlogged until the seeds have sprouted.
  5. Protect your seeds: To prevent birds from feasting on your seeds, cover them with a layer of netting or row cover until they sprout.

Pro tip:

If you’re planting a fall crop, consider planting in containers. This allows you to move your peas indoors during extreme temperature fluctuations or unexpected frosts.

Providing Adequate Support for Pea Plants

Pea plants in Colorado require support structures to prevent them from falling over and to increase productivity. Without adequate support, pea plants may become entangled, making it challenging to harvest them. Therefore, gardeners should set up a support system as soon as pea seedlings are about four inches tall.


A popular support structure is a trellis, which is made of wood, bamboo, or metal. Gardeners should install the trellis at least six feet tall to provide enough room for the peas to grow. The trellis must be sturdy enough to bear the weight of the pea plants and withstand wind and rain. Pea vines will naturally wrap around the trellis as they grow, and gardeners can gently guide the vines in the right direction as needed.


Another option is using stakes, which are inserted into the ground beside each pea plant. The stakes should be at least six feet tall and sturdy enough to support the weight of the plants. Gardeners can tie the pea plants to the stakes using twine or garden tape. Staking is ideal for smaller gardens or when only a few pea plants are being grown.

Wire Cages

Gardeners can use wire cages to support pea plants by wrapping the wire around the plants. Wire cages come in different sizes and can be purchased or created with wire mesh. This method is ideal for gardeners who have limited space or want to grow peas in containers.

Providing proper support for pea plants in Colorado helps increase yield, prevent eye-level pea pods, and make harvesting easier. Gardeners should also prune the plants occasionally to promote air circulation and prevent disease.

Maintaining Pea Plants in Colorado

Once your pea plants are established, it’s important to maintain them properly to ensure a bountiful harvest. Here are some essential tips for maintaining your pea plants in Colorado:

  1. Watering: Peas need consistent moisture to thrive, especially during hot and dry weather. Water deeply once or twice a week, making sure to avoid overhead watering which can increase the risk of disease.
  2. Weed Control: Weeds can compete with your pea plants for nutrients and water, so it’s important to keep them at bay. Regular hand weeding or mulching can help to minimize weeds in your pea beds.
  3. Pest Management: Pea plants can be susceptible to a variety of pests, including aphids, cutworms, and spider mites. Regular inspection and treatment with organic insecticides can help to prevent infestations and protect your plants.
  4. Disease Prevention: Pea plants can also be vulnerable to several diseases, such as powdery mildew and root rot. To minimize the risk of disease, plant disease-resistant varieties, practice crop rotation, and maintain good air circulation around your plants.

By following these maintenance practices, you can help ensure that your pea plants stay healthy and productive throughout the growing season.

Troubleshooting Pea Growth Issues in Colorado

Despite your best efforts, growing peas in Colorado can sometimes present challenges. Here are some common pea growth issues and solutions to overcome them:

Stunted Growth

If your pea plants appear stunted, it may be due to poor soil conditions or insufficient water. Ensure that your soil is well-draining and fertile, and water your plants regularly to prevent drought stress. Consider adding a balanced fertilizer to improve plant growth.

Yellowing Leaves

Yellowing leaves can be a sign of nutrient deficiencies or pest infestations. Conduct a soil test to check nutrient levels and adjust accordingly. If pests are the issue, use organic pest control methods such as neem oil or insecticidal soap to protect your plants.

Pest Infestations

If your pea plants are experiencing pest infestations, such as aphids or spider mites, try using natural pest control methods such as spraying plants with water to remove pests or introducing beneficial insects like ladybugs into your garden.


Pea plants in Colorado can be susceptible to various diseases such as powdery mildew or root rot. To prevent disease, ensure good air circulation around plants and avoid overwatering. If disease does occur, remove infected plants or plant parts and dispose of them properly to prevent further spread.

By using these troubleshooting tips and strategies, you can overcome common pea growth issues and continue to cultivate a thriving pea garden in Colorado.

Harvesting Peas in Colorado

Knowing when to harvest your pea plants is crucial for producing the best-tasting peas in Colorado. The key is to strike the right balance between harvesting when the peas are ripe and leaving them on the vine too long, which can lead to toughness and loss of flavor.

Monitor your pea plants regularly and look for signs that the pods are ready for picking. Pods should be filled out but still have a bright green color. Press your fingernail against the pod to see if it leaves a dent. If it does, the peas are ready to harvest.

Proper Harvesting Techniques

When you are ready to harvest, use one hand to hold the vine and the other to gently pull the pod off. Avoid yanking the pods off the vine, as this can damage the plant and reduce future yields.

Harvest your peas frequently to encourage continued production and prevent over-ripening. If left on the vine too long, peas can become tough and lose their flavor.

Storing Freshly Picked Peas

If you are not using your freshly picked peas right away, store them in the refrigerator to maintain their quality and flavor. For best results, place the pods in a breathable plastic bag and store them in the crisper drawer.

Peas can also be blanched and frozen for future use. To do this, steam or boil the peas for 1-2 minutes, then plunge them into icy water to stop the cooking process. Drain and place the peas in a freezer-safe container or bag, label with the date, and store in the freezer for up to 6 months.

Enjoying the Fruits of Your Labor

Congratulations! You have successfully grown delicious and nutritious peas in Colorado. Now it’s time to enjoy the fruits of your labor. There is nothing quite like the taste of fresh, homegrown peas, and you can savor them in a variety of ways.

Pea Recipes to Try

One classic way to enjoy peas is to serve them as a side dish. Cook them with butter and a pinch of salt for a simple and tasty addition to any meal. You can also add peas to soups, stews, and casseroles for extra flavor and nutrition.

Peas also make a great addition to salads. Toss them with mixed greens, sliced almonds, and a vinaigrette dressing for a refreshing and healthy meal. Alternatively, you can try making a pea puree to use as a dip or spread for sandwiches and crackers.

Preserving Your Pea Harvest

If you have a large pea harvest, you might want to consider preserving some for later use. Peas freeze well and can be stored for up to six months. Blanch them in boiling water for a few minutes, then transfer them to airtight containers or freezer bags.

Canning is another option for preserving peas. Pressure canning is recommended for safe preservation, but you can also water-bath can them if you add acid (such as vinegar) to the jars.
