How to plant seed potatoes?

Plant them with the shoots just below the soil surface c. 18 inches apart. The reason for the spacing distance is that you need to be able to draw surrounding soil up to the foliage as it grows, to ensure that the developing potatoes are always covered. Exposure of the potatoes to sun and light would turn them green and poisonous. An alternative is to heap on soil/compost from another source, as you go along. Best of luck (but I'm no spud expert).

Better to plant the tubers a spade depths deep than just under the surface. Then as the shoots emerge from the soil cover all but the top two leaves with soil until all danger of frost has passed. 3 fold advantage, no frost damage, no green potatoes and more roots, thus more potatoes.
