About Yacon Seeds

Grow your own Yacon (Smallanthus sonchifolius), a nutritious root vegetable prized for its sweet, crisp tubers. Ideal for home gardens or farm plots, Yacon is easy to grow, drought-tolerant, and can be eaten fresh, roasted, or used in salads and preserves.

Planting Time:

  • Best sown in spring after the last frost, when soil temperatures are 18°C–25°C (65°F–77°F).

  • Prefers full sun and fertile, well-draining soil.

  • Germination typically occurs in 2–4 weeks under warm, moist conditions.

  • Harvest tubers in 6–8 months after planting, depending on climate and care.

Planting Guide

Sow Yacon in spring at about 1/2 in. deep. Keep the soil consistently moist until germination, usually 14-30 days.
