How do you grow Jerusalem artichokes?
Posted by Dobies Staff on 18 December 2013 12:41 pm

Jerusalem Artichokes will thrive in any well drained soil in full sun or partial shade. Dig the site in autumn or early winter incorporating well rotted garden compost. Plant the tubers from late February to mid April in rows 90cm (36″) apart. In the row space the tubers 38-45cm (15-18″) apart and plant them 12.5cm (5″) deep.

When the plants are about 30cm (12″) in height, earth up around the base of the plant. The plants will reach a height of approximately 1.5m (5ft) and in exposed positions support wires should be provided each side of the plants. Flower buds should be removed as they develop to encourage tuber development. Keep the plants well watered in dry spells and occasionally apply a liquid feed.

The tubers are harvested as required from October to early spring. Once the foliage has turned brown it should be cut back to approximately 30cm (12″) from the ground. Lift the tubers as required for immediate use. In severe weather, cover the plants with straw or soil for added protection and to aid lifting in cold frosty conditions. At the end of the harvesting period make sure that all the tubers have been dug up, as any left in the soil will re-grow in spring.
