Rhubarb is a hardy, long-lived perennial valued for its handsome leaves and tart spring stalks. Once established in a well-chosen bed, it needs little fuss and can crop for years. Give each crown space, fertile ground and dependable drainage for the strongest plants.

When and how to sow

Plant dormant crowns, often called sets, from autumn until early spring, placing their buds just at soil level in rich, well-manured, well-drained ground. Space crowns 90 cm apart in sun or light shade. Pot-grown plants can be planted during the growing season if kept watered. Avoid waterlogged positions, and do not harvest any stalks in the first year while the crown establishes.

Care

Mulch annually with well-rotted organic matter and water during prolonged dry spells. Remove flowering stems promptly, as they divert energy from stalk production. In late winter, cover an established crown with a bucket or forcing jar, excluding light, for an early crop of tender pink stalks. Uncover afterwards to let leaves recover.

Common problems

Crown rot is the chief concern and is most likely in poorly drained or permanently wet soil. Lift and discard badly affected crowns rather than composting them. Slugs may shelter beneath leaves, while weak, thin stalks can indicate crowding. Keep the bed weed-free and divide vigorous old crowns when necessary.

Harvest

From the second year, pull a few stalks in spring; established plants can be picked regularly from spring to midsummer. Grasp each stalk low down and twist it away cleanly. Stop harvesting by July so the crown can rebuild. Discard leaves and use only the stalks, as the leaves are not eaten.
