Pot up Oca tubers individually into 15cm (6") pots of good quality compost and grow them on in warm, frost free conditions. When all risk of frost has passed, plant Oca out in any well drained soil in full sun. For optimum tuber production grow Oca at a distance of 90cm (36") apart, and cover with fleece until fully established.
Water Oca regularly, particularly during dry periods and especially from mid September when tubers begin to develop. An occasional feed with a general fertiliser and a mulch of well rotted compost will also help to encourage strong growth.
Oca requires long day lengths to grow and will not initiate tuber production until day lengths shorten in the autumn. Some tubers may form on the stems and these should be harvested before the first frosts. Do not harvest the underground tubers until the foliage has become frosted and died back in late November and December. Carefully lift tubers taking care not to bruise them. Oca tubers can be stored for several months in a cool frost free shed. Do not exclude light as this will help to sweeten the tubers.

Kiwi favourite but enjoyed by all

For me it was like a taste of home when I proudly dug them up. Planted some in large pots and rest in a vegetable bed and the ones in the vege bed definitely did best. They were so easy to grow and it was great to have a plant I didn't have to protect from the frost. Had them roasted with Christmas dinner and pretty much continuously post that. Have kept some aside to plant this year and they have kept well. Highly recommended by a New Zealander (they are a staple veg at home) and also our British friends!
Oca is more than a novelty winter vegetable.

These grew really well on my sandy soil and each tiny tuber yeilded lots of good sized delicious tubers. I protected the plants after the leaves were cut back by frost and suffered no problems with the winter weather in North Nottinghamshire. They have stood beautifully for lifting right through the winter.
Great raw with their crisp tangy flavout but also superb roasted or stir fried.
This will will be a staple for me in future and a great addition to the winter table.
