Germination •Each seed potato has a more rounded, blunt end that has a number of 'eyes'. •Spread the tubers out in boxes, crates or old egg boxes one layer deep, with the blunt end up, and bring them into a warm, sunny location. •The potatoes are ready to be planted out when the sprouts are up to 3 cm (1 in) long. Planting •You can start planting your seed potatoes 2 weeks after the last spring frost. •Choose a planting spot in full sun and well-drained, loose soil. •Be sure to spade or loosen the soil extremely well. Potatoes will not grow in hard or compact soil. •Place the tubers with the sprouts facing up in shallow trenches 15 cm (6 in) wide, space them 20 to 30 cm (8 to 12 in) apart, and cover with 8 cm (3 in) of soil. •Water thoroughly after planting. Growing •Potatoes need consistent moisture, so water regularly when tubers start to form. •As soon as the shoots appear, earth up each plant by covering it with a ridge of soil so that the shoots are just buried. •You need to do this at regular intervals and by the end of the season each plant will have a small mound around it about 15 cm (6 in) high. Harvest •You can harvest potatoes in stages - "young" or "early" potatoes should be ready about 10 weeks after planting (when the flowers appear). Take a few without pulling up the stems, and leave others to continue growing into full-sized potatoes. •For storage of full-sized potatoes, wait until the foliage turns yellow, then cut and remove. Leave for 10 days before harvesting the tubers. •After harvesting, leave the tubers on the soil surface for a few hours to dry. •Once dry store them in a dark, cool but frost free place.
