Some of us have tubers of Oca, thanks to this year’s seedling swap. I have found a useful website, see below, explaining how to grow these but the key points seems to be:
- Do not harvest the underground tubers until the last remnants of foliage has become frosted and died off from late November and into December.
- Each tuber makes quite a bushy plant so allow at least 90cm (36″) between plants
