How do you sprout seed potatoes for a crop of small tubers?
Chitting can bring forward the harvest of early varieties, but it is not essential. Choose certified seed potatoes that are firm and healthy, rather than tubers sold for eating.
Arrange them in a single layer, with the eyes uppermost, in egg boxes or trays. Keep them somewhere cool, bright and frost-free for a few weeks to develop short, sturdy sprouts. Handle them gently at planting to avoid breaking the sprouts. Prepare fertile soil too: the tuber's reserves do not replace soil nutrients.
