Pea seeds benefit from a pre-soak to soften their outer coat, speeding up the germination process. This simple step is one of the first things you need to know about how to grow peas from seed. Growing your own peas is rewarding, and it starts with the seed.
Peas are a cool-season crop. They love the early spring weather. You can also plant them in late summer for a fall harvest. This guide will walk you through every step.
How To Grow Peas From Seed
Let’s get right into the process. You’ll learn about soil, planting depth, watering, and care. Follow these steps, and you’ll have sweet peas in no time.
Why Grow Peas From Seed?
Starting from seed gives you more variety. You can choose shelling peas, snow peas, or snap peas. Seeds are also cheaper than buying transplants. Plus, peas don’t like their roots disturbed. Direct sowing is best.
Choosing The Right Pea Variety
Pick a variety that suits your climate and taste. Here are some common types:
- Shelling peas: You remove the pods. Examples are ‘Lincoln’ and ‘Green Arrow’.
- Snow peas: You eat the flat pods. Try ‘Oregon Sugar Pod II’.
- Snap peas: You eat the whole pod, which is thick and sweet. ‘Sugar Snap’ is a classic.
Check your local growing season. Peas need cool weather to set pods. If it gets hot fast, choose a quick-maturing variety.
When To Plant Pea Seeds
Timing is crucial. Plant as soon as the soil can be worked in spring. The soil temperature should be around 45°F to 70°F (7°C to 21°C). Peas can tolerate light frosts. In fact, they taste sweeter after a light frost.
For a fall crop, plant about 8 to 10 weeks before the first expected frost. The soil will be warmer, so keep it moist.
Preparing The Soil For Peas
Peas grow best in well-drained soil. They don’t need rich soil. Too much nitrogen will give you lots of leaves but few pods. Here’s how to prepare:
- Choose a sunny spot. Peas need at least 6 hours of sun daily.
- Loosen the soil to about 8 inches deep.
- Mix in some compost or well-rotted manure. This adds organic matter.
- Check the pH. Peas like a pH between 6.0 and 7.5.
Avoid fresh manure. It can burn the seeds. Also, don’t add too much nitrogen fertilizer.
Pre-Soaking Pea Seeds
This is the tip from the opening. Soaking helps soften the seed coat. It can speed up germination by a few days. Here’s how:
- Place seeds in a bowl of warm water.
- Let them soak for 8 to 12 hours. Overnight works well.
- Drain and plant immediately. Don’t let them dry out.
Some gardeners skip this step. It’s not required, but it helps. If you plant in wet soil, you might not need to soak. But for most, it’s a good habit.
How To Plant Pea Seeds
Planting depth and spacing matter. Follow these steps:
- Make a trench about 1 inch deep. In heavy clay soil, plant only ½ inch deep.
- Space seeds about 2 inches apart. You can plant them closer and thin later.
- Cover the seeds with soil and pat gently.
- Water well after planting. Keep the soil moist but not soggy.
If you’re planting multiple rows, space rows about 18 to 24 inches apart. This allows air circulation and easy harvesting.
Providing Support For Pea Plants
Most pea varieties need support. They climb using tendrils. Without support, they’ll sprawl on the ground. This can lead to rot and disease. Here are support options:
- Trellis netting: Stretch it between posts. Peas grab onto it easily.
- Pea fencing: Wire mesh or chicken wire works well.
- Bamboo stakes and twine: Create a simple teepee or grid.
Install supports at planting time. If you wait, you might damage the roots later. Peas can climb up to 6 feet tall for some varieties.
Watering Pea Plants
Consistent moisture is key. Peas need about 1 inch of water per week. More during flowering and pod development. Here are some tips:
- Water at the base of the plant. Avoid wetting the leaves to prevent mildew.
- Use drip irrigation or a soaker hose. This keeps the soil evenly moist.
- Mulch around the plants. Straw or grass clippings help retain moisture and keep roots cool.
Don’t overwater. Peas don’t like waterlogged soil. Check the soil by sticking your finger in. If it’s dry an inch down, it’s time to water.
Fertilizing Peas
Peas are light feeders. They fix their own nitrogen from the air. That’s why they don’t need high-nitrogen fertilizers. Here’s what to do:
- If your soil is poor, add a balanced fertilizer (like 10-10-10) at planting time.
- Once plants are 6 inches tall, side-dress with compost or a low-nitrogen fertilizer.
- Avoid over-fertilizing. It leads to lush leaves and few pods.
Peas also benefit from phosphorus and potassium. These help with flower and pod development.
Common Pests And Diseases
Peas have a few common problems. Here’s how to handle them:
Aphids
These small insects suck sap from leaves. You can spray them off with water or use insecticidal soap. Ladybugs are natural predators.
Powdery Mildew
This fungal disease looks like white powder on leaves. It happens in humid conditions. Prevent it by spacing plants well and watering at the base. Use resistant varieties if possible.
Pea Weevil
This pest lays eggs in flowers. The larvae eat the seeds. Rotate crops and use row covers to prevent them.
Root Rot
This happens in wet soil. Improve drainage and avoid overwatering. Rotate crops every year.
Harvesting Peas
Harvesting at the right time is important. Here’s when to pick each type:
- Snow peas: Harvest when pods are flat and seeds are just visible. They should be tender.
- Snap peas: Harvest when pods are plump and crisp. You can eat the whole pod.
- Shelling peas: Harvest when pods are full and round. The seeds should be sweet and tender.
Pick peas every day or two. This encourages more production. Use two hands to avoid damaging the vine. Hold the vine with one hand and pull the pod with the other.
Storing Fresh Peas
Peas taste best right after picking. But you can store them for a short time. Here’s how:
- Keep unwashed peas in a plastic bag in the fridge. They’ll last about 5 days.
- Blanch and freeze peas for longer storage. Boil them for 1-2 minutes, then plunge into ice water. Drain and freeze in bags.
- You can also dry peas for soups. Let them mature on the vine until the pods are brown and dry.
Succession Planting For Continuous Harvest
To extend your harvest, plant seeds every 2 to 3 weeks. This works well in spring. Once summer heat arrives, peas stop producing. For a fall crop, plant again in late summer.
Choose early, mid, and late-season varieties. This gives you a longer harvest window.
Common Mistakes To Avoid
Here are some pitfalls to watch out for:
- Planting too late: Peas hate heat. Plant early in spring.
- Overwatering: This causes root rot. Water only when needed.
- No support: Vines on the ground get diseased. Always provide a trellis.
- Harvesting too late: Overripe peas are starchy and tough. Pick often.
- Ignoring crop rotation: Don’t plant peas in the same spot every year. Rotate with other crops to prevent disease.
Growing Peas In Containers
You can grow peas in pots if you have limited space. Choose a container at least 12 inches deep. Use a well-draining potting mix. Provide a trellis or cage for support. Dwarf varieties work best in containers. Water more often because pots dry out faster.
Companion Planting With Peas
Peas get along with many plants. Good companions include:
- Carrots
- Radishes
- Spinach
- Lettuce
- Beans
Avoid planting peas near onions or garlic. They can stunt pea growth.
Saving Pea Seeds For Next Year
You can save seeds from open-pollinated varieties. Here’s how:
- Let some pods mature on the vine until they turn brown and dry.
- Pick the pods and remove the seeds.
- Spread the seeds on a screen to dry for a week.
- Store in a cool, dark place in a paper envelope. Label with the variety and year.
Seeds can last 3 to 4 years if stored properly. Don’t save seeds from hybrid varieties. They won’t grow true.
Frequently Asked Questions
How long does it take to grow peas from seed?
Most peas take 55 to 70 days from planting to harvest. Snow peas and snap peas are often faster. Check your seed packet for exact days.
Can I grow peas in hot weather?
Peas prefer cool weather. They stop producing when temperatures exceed 85°F (29°C). Plant early in spring or in late summer for fall harvest.
Do pea seeds need light to germinate?
No, pea seeds germinate in the dark. They need soil contact and moisture. Once they sprout, they need light to grow.
Why are my pea seeds not germinating?
Common reasons include cold soil, dry soil, or old seeds. Peas need soil above 40°F (4°C) to germinate. Soaking seeds can help. Also, check the seed packet for viability.
Can I plant peas in the same spot every year?
It’s not recommended. Crop rotation helps prevent soil-borne diseases. Wait at least 3 years before planting peas in the same spot.
