It’s easy to grow your own kumara tipu for planting out in November: choose an unblemished, healthy tuber and nestle it into a pot or box filled with damp sand, woodchips or sawdust. Keep the pot somewhere warm, like the laundry cupboard, to stimulate the ‘eyes’ to sprout.
In a week or three you’ll see the first new shoots sprouting through the sand. This is your cue to provide fresh air and sunshine during the day...and as those shoots green up and grow, you'll soon be looking for homes for them all :)
