Grower’s Reference Guide: Pea
Introduction
Peas (Pisum sativum) are a cool-season legume that is highly nutritious and easy to grow. They are known for their sweet, tender pods and are a valuable crop in organic gardens due to their ability to fix nitrogen in the soil. Growing peas organically ensures a bountiful, chemical-free harvest while improving soil health.
Fun Fact: Peas were one of the first cultivated crops and have been grown for over 7,000 years!

Propagation & Seed Starting
- Growing From Seed:
- Seed Selection: Choose organic, non-GMO seeds
- Harvesting Seeds: Allow pods to dry on the vine before collecting seeds
- Germination: 7-14 days at 50-70°F
- Propagation: Best grown directly from seeds; transplants can struggle to establish
- Transplanting: Avoid disturbing roots; sow seeds directly in their final location
Cultivation & Maintenance
- Organic Fertilizers: Compost, fish emulsion, and aged manure
- Mulching: Use straw or grass clippings to retain moisture and suppress weeds
- Pruning/Training: Provide trellises for climbing varieties; prune for airflow
- Seasonal Care: Protect young plants from extreme cold with row covers
Pests & Diseases
- Common Diseases: Powdery mildew, root rot, and pea mosaic virus (prevent with crop rotation and proper spacing)
- Pest Management:
- Common Pests: Aphids, pea weevils, and caterpillars
- Organic Prevention: Neem oil, insecticidal soap, and interplanting with pest-repellent herbs
Harvesting
- When & How:
- Snap & Snow Peas: Harvest when pods are plump but still tender
- Shelling Peas: Pick when peas inside pods are fully formed but not hard
- Dried Peas: Allow pods to dry on the plant before collecting
- Tools: Hands or pruning shears
- Signs: Pods should be firm but not tough; sweet aroma when opened
Storage & Preservation
- How to Store: Refrigerate fresh peas for up to a week
- How to Preserve: Blanch and freeze or dry for long-term storage
- Seed Saving: Allow pods to fully dry before collecting seeds for future planting
Usage & Nutrition Information
- Edibility: Entire plant is edible, including pods, leaves, and tendrils

Troubleshooting
- Common Issues:
- Yellowing Leaves: Overwatering or nitrogen deficiency
- Few Pods: Poor pollination or high temperatures
- Pest Damage: Use organic deterrents like neem oil and floating row covers
Frequently Asked Questions
- Why are my peas not producing pods? High temperatures or poor pollination can reduce pod production.
- Can I grow peas in containers? Yes, use a deep container (at least 8 inches) with well-draining soil.
- How long does it take for peas to grow? Typically 60-70 days, depending on variety.
