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.
