Pigeon Pea, Green (Cajanus cajan)
This tropical legume is famous and loved in Caribbean cuisine and beyond. Pigeon pea is grown widely throughout the tropics and subtropics as a perennial evergreen and nitrogen fixer that provides protein rich peas.
Pigeon Pea is a hardy and versatile tree/shrub that can grow in a wide range of low fertility soils and soil textures and will reach about 6ft tall, 3ft wide. Pollinators love the very attractive bright yellow-orange unique pea flowers.
Peas are super nutritious and full of protein! They have a nutty taste/texture and can be harvested 5-8 months after planting. Pigeon pea improves soil content and soil structure, is ideal for 'chop and drop' mulching, and when planted close together quickly forms a thick hedge or living wall for a perfect natural windbreak. Pigeon Pea is one of our favorite fast growing, drought resistant, extremely versatile permaculture plant.
How to Grow Pigeon Pea Plants
Climate and Soil Requirements
- Climate: Pigeon Peas thrive in warm, tropical, and subtropical climates. They are best suited for USDA hardiness zones 9-11. The plants prefer temperatures between 70-95°F and can tolerate dry conditions, making them ideal for arid and semi-arid regions.
- Soil: Prefers well-draining, loamy soil with a slightly acidic to neutral pH (5.5-7.0). Pigeon Peas can adapt to poor soils but perform best in fertile, well-amended ground.
Planting
- Location: Choose a sunny location that receives at least 6-8 hours of direct sunlight daily. Pigeon Peas can also tolerate partial shade but will produce better yields in full sun.
- Soil Preparation: Prepare the soil by tilling and adding compost or organic matter to improve fertility and drainage.
- Planting Time: Plant seeds directly in the garden after the last frost date when the soil has warmed to at least 70°F. In cooler climates, start seeds indoors 4-6 weeks before the last frost and transplant them outdoors once the danger of frost has passed.
- Spacing: Plant seeds 1-2 inches deep and space them 18-24 inches apart in rows spaced 3-4 feet apart to allow adequate room for growth and air circulation.
Watering
- Establishment Phase: Water regularly to keep the soil consistently moist but not waterlogged during the first year. Consistent moisture is crucial for young plants.
- Mature Plants: Once established, Pigeon Peas are drought-tolerant. Water deeply and less frequently, allowing the top inch of soil to dry out between waterings.
Sunlight
- Full Sun: Ensure the plants receive at least 6-8 hours of direct sunlight daily for optimal growth and pod production.
Fertilizing
- Growing Season: Apply a balanced, slow-release fertilizer in early spring to promote healthy growth. Supplement with organic matter or compost.
- Frequency: Fertilize every 4-6 weeks during the growing season.
Pruning and Maintenance
- Routine Pruning: Prune in late winter or early spring to shape the plant and remove any dead or diseased branches. Light pruning encourages bushier growth and improves air circulation.
- Maintenance: Pigeon Pea requires minimal maintenance once established. Mulch around the base to retain moisture and suppress weeds.
Pest and Disease Management
- Common Pests: Monitor for pests such as aphids, caterpillars, and pod borers. Use insecticidal soap or neem oil to control infestations. Encouraging beneficial insects can also help manage pests.
- Diseases: Watch for signs of fungal diseases such as root rot and leaf spot. Ensure proper spacing, good air circulation, and avoid overhead watering to reduce disease risk. Apply fungicides if necessary.
Harvesting Pods
- When to Harvest: Harvest pods when they are fully mature and have reached their full color—black, green, or red. Pods can be harvested at different stages depending on whether you want fresh peas or dried seeds.
- How to Harvest: Use scissors or pruning shears to cut the pods from the plant, taking care not to damage the main stems.
