How to Grow Peas in New Hampshire

Growing peas can be a rewarding experience for gardeners in New Hampshire. The state’s climate and soil conditions are suitable for several varieties of peas, including garden peas, snap peas, and snow peas. This article will guide you through the process of growing peas in New Hampshire, from selecting the right variety to harvesting your delicious crop.

Understanding Pea Varieties

Before diving into the gardening process, it’s important to understand the different types of peas available:

• Garden Peas (Pisum sativum): Also known as shelling peas, these are the classic sweet peas that need to be shelled before eating.
• Snap Peas (Pisum sativum var. macrocarpon): These have edible pods and are sweet and crisp. They can be eaten fresh or cooked.
• Snow Peas (Pisum sativum var. saccharatum): These pea varieties have flat pods and are harvested while still immature. They are also edible and often used in stir-fries.

Choosing the right variety will depend on your preferences for eating and cooking.

Choosing the Right Time to Plant

Peas thrive in cool weather, making New Hampshire’s climate ideal for their growth. The best time to plant peas is in early spring, as soon as the soil can be worked. In most parts of New Hampshire, this is typically between mid-April and early May. The soil temperature should be around 45°F for optimal germination.

Tips for Timing Your Planting

• Frost Dates: Check local frost dates; it’s crucial to plant peas after the last frost has passed but before the heat of summer sets in.
• Succession Planting: To maximize your harvest, consider planting a second crop in late summer for a fall harvest. This is especially true for snap peas, which can tolerate slightly warmer temperatures.

Preparing Your Garden Soil

Peas grow best in well-drained, fertile soil with a pH level between 6.0 and 7.5. Here’s how to prepare your garden bed for planting:

Soil Testing

Before planting, conduct a soil test to determine its nutrient content and pH level. Most local cooperative extension services offer testing services at reasonable prices.

Amending Soil

Based on the results of your soil test, you may need to amend your soil with organic matter such as compost or well-rotted manure. This not only boosts fertility but also improves soil structure and drainage.

Tilling and Raking

• Tilling: Use a garden fork or tiller to loosen the top 12 inches of soil.
• Raking: Level out the bed using a rake, breaking up any large clumps of soil.

Planting Peas

Once your soil is prepared, it’s time to plant!

Seed Selection

Purchase high-quality seeds from local nurseries or trusted online retailers. Look for varieties well-suited for New Hampshire’s climate.

Planting Technique

1. Row Spacing: Create rows spaced about 2 feet apart.
2. Seed Depth: Plant seeds approximately 1 to 2 inches deep.
3. Seed Spacing: Space seeds about 1 inch apart within each row.
4. Watering: Water gently after planting to ensure good seed-to-soil contact.

Trellising

If you’re growing climbing varieties like snap or snow peas, set up a trellis at planting time. This could be made from stakes and twine or a commercial trellis system.

Caring for Your Pea Plants

Watering

Peas require consistent moisture throughout their growing season but avoid waterlogging. Aim for about an inch of water per week, particularly during dry spells.

Weeding

Regular weeding is essential as they compete with your pea plants for nutrients and water. Mulching around your plants can help suppress weeds while retaining moisture.

Fertilizing

While legumes like peas fix nitrogen in the soil through symbiotic relationships with Rhizobium bacteria, they may benefit from additional nutrients if the soil is deficient:

• Use a fertilizer low in nitrogen but rich in phosphorus (such as bone meal) during planting.
• Avoid high-nitrogen fertilizers, which can promote excessive foliage growth at the expense of pod development.

Pest Control

Common pests include aphids and pea weevils:

• Aphids: These small insects can be controlled by introducing beneficial insects or using insecticidal soap.
• Pea Weevils: Prevent infestation by rotating crops each year and cleaning up debris after harvest.

Supporting Growth

As your plants grow taller, they may need additional support:

• For small trellises or supports, consider using bamboo stakes or netting.
• Ensure that climbing vines are encouraged to naturally wrap around supports as they grow.

Harvesting Peas

Timing is critical when harvesting peas. Different varieties have different maturity times:

• Garden Peas: Harvest when the pods are full but still tender—usually about 60–70 days after sowing.
• Snap Peas: Harvest when the pods are crisp and full but before they turn yellow—typically about 60 days after sowing.
• Snow Peas: Pick when pods are flat and still tender—around 50 days after sowing.

Gently pull pods from the vine without tearing them off to avoid damaging the plant.

Storing Peas

Freshly harvested peas taste best when consumed immediately but can also be stored:

• Refrigeration: Store unwashed peas in perforated plastic bags in the refrigerator crisper drawer for up to a week.
• Freezing: For longer storage, blanch peas briefly in boiling water then freeze them in airtight containers or freezer bags.

Conclusion

Growing peas in New Hampshire can be an enjoyable endeavor that rewards gardeners with fresh produce. By understanding their unique needs regarding timing, soil preparation, watering, and pest management, you can cultivate a thriving pea crop throughout the growing season. With proper care and attention, you’ll enjoy delicious homegrown peas that add flavor and nutrition to your meals!
