The large roots of the sweet potato are a rich source of vitamin C, E and B and the more orange-coloured have a similar vitamin A content to carrots. They can't be grown from tubers so are supplied as cuttings or 'slips'. Each slip produces roots and a new plant develops. Grow under cover, through black polythene or in large containers. Lift and store unblemished roots in a warm place (10-15OC), like pumpkin/winter squashes. They must not become too cold and never frosted.
Important: On receipt, put the slips in water for a few days to revive before planting. Full care instructions are included.
