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.

I ordered these as I had grown and eaten them when living in New Zealand and wanted to grow some here. The pack arrived with five of the tiniest tubers I've ever seen, they were badly dehydrated, and the flesh was damaged. Not good quality produce for growing from at all, and very different in looks from those displayed in your photograph. To say that I am disappointed is an understatement. I have come to expect better from T&M, these simply won't do the job they need to do.

great alternative to potatoes
By Joelle Nicholson 10-08-2014
I first came across these in NZ and loved them. They make a great alternative to potatoe wedges. I had to wait 10 years for them to appear in this country and was delighted to find them at T&M. I have had years of blight up in Scotland so wanted an alternative to potatoes and this year have replaced half of them with this crop in my allotment.
