Planting & Sprouting
3-4 weeksCorms are planted in prepared soil; initial shoots emerge from the corm
Ensure soil is warm (minimum 60°F, ideally 70-85°F). Keep soil evenly moist. Mulch to retain moisture and maintain temperature.
Vegetative Growth
4-6 monthsLarge, arrow-shaped leaves develop; the plant establishes a strong root and shoot system
Provide consistent moisture and humidity. Apply balanced fertilizer monthly (NPK 10-10-10). Remove any weak or diseased leaves. Ensure adequate spacing for air circulation.
Leaf Maturation
2-3 monthsFoliage reaches full size; leaves can be harvested for cooking while plant continues to develop corms
Harvest outer mature leaves carefully without damaging the plant. Continue regular watering and monthly feeding. Mulch heavily to keep soil consistently moist.
Corm Development
2-4 monthsUnderground corms expand and accumulate starch; plant may slow visible top growth
Reduce nitrogen fertilizer; apply potassium-rich fertilizer to support tuber enlargement. Maintain consistent moisture. Reduce leaf harvesting to allow energy to focus on tuber development.
Harvest Ready
Variable, typically 8-12 months totalCorms reach mature size (6-12 inches); foliage may yellow slightly
Stop watering 1-2 weeks before harvest to allow soil to dry slightly for easier harvesting. Look for signs of plant senescence. Carefully dig corms to avoid damage.

Harvest Tips
Harvest leaves individually starting 4-6 months after planting by cutting mature outer leaves at the petiole, leaving younger center leaves. Dig corms 8-12 months after planting when foliage begins to yellow. Carefully excavate around the plant to avoid damaging tubers. Handle corms gently as they bruise easily. Use a fork or spade to loosen soil before pulling. Store in cool, dark, well-ventilated location.
Fun Facts
- 🌱 Zampa is also called 'malanga', 'tannia', 'cocoyam', and 'taro' (though distinct from true taro); it is a staple in African diaspora cuisines from the Caribbean to Brazil.
- 🌱 A single zampa plant can produce 8-15 corms from one planted corm, making it highly productive and economical for small-scale farmers.
- 🌱 Zampa leaves contain oxalates and must be cooked thoroughly to be safely edible; cooking breaks down these compounds and also improves digestibility.
