Oxalis tuberosa Second only to potato cultivation in South America, Oca is a tuberous crop that is as diverse as it is unique.

Oca has clover-shaped leaves on a compact, 10-12 inch tall plant that can spread 2-3 feet wide and tolerates a wide pH range. Grown and cultivated very similarly to potatoes, it prefers well-drained, fertile soil. Oca begins forming tubers in autumn. Can overwinter in zones 7 and above.

Harvest & Storage
In the autumn dig the tubers as you would potatoes and store in a cool, frost-free place. Sun dry the versatile tubers to bring out their sweetness. Save some tubers to replant in the spring.

Initial Instructions
After unpacking, allow the plant a few days to gradually acclimate to its full exposure. Plant your Oca in an area with well-drained, not soggy soil. Plants prefer partial shade and cool, damp conditions.

Oca is day length sensitive and will not start forming tubers until late fall. Keep plant well watered throughout the growing season. For highest yields, protect plants when cold weather arrives by mulching or using a season extender such as Reemay or Gro-Therm. Harvest can occur when the plant naturally dies back in November/December.
