Elephant Foot yam Healthy Corm

Growing an elephant foot yam corm (also called suran or Amorphophallus paeoniifolius) is straightforward if you provide warmth, moisture, and rich soil.

1. Choose a healthy corm

• Select a firm, disease-free corm.
• If it’s large (over 500 g), you can cut it into pieces, ensuring each piece has at least one visible bud (“eye”).
• Allow cut pieces to dry and heal for 2–3 days in a shaded, airy place before planting.

2. Prepare the soil

Elephant foot yam prefers:

• Loose, well-drained, fertile soil
• Plenty of organic matter (compost or well-rotted manure)
• Soil pH of about 5.5–7.0

Avoid waterlogged areas, as the corm can rot.

3. Planting

• Plant during the warm rainy season or after the danger of frost has passed.
• Dig a hole about 10–15 cm (4–6 inches) deep.
• Place the corm with the bud facing upward.
• Cover with soil and mulch.

Spacing

• Small corms: 45–60 cm apart
• Large corms: 75–90 cm apart

4. Watering

• Water lightly after planting.
• Keep the soil evenly moist but not soggy.
• Once the plant is actively growing, water regularly, especially during dry periods.

5. Fertilizing

Mix compost into the soil before planting. During growth:

• Apply a balanced fertilizer every 4–6 weeks.
• Potassium-rich fertilizers help produce larger corms.

6. Care

• Remove weeds regularly.
• Mulch to conserve moisture.
• The plant grows one large umbrella-like leaf from the corm.
• Avoid disturbing the roots during the growing season.

7. Harvest

• Harvest 7–9 months after planting.
• The leaf will naturally yellow and die back when the corm is mature.
• Carefully dig around the plant to avoid damaging the corm.
