About

Native to the Andes region, it is a fundamental tuber crop in global human nutrition. It requires attention to keep the tubers covered and prevent them from developing a green colour and toxicity. In the food forest, it occupies the root and tuber layer during the warm season.

It is harvested now — September is one of the harvest months.
