Wood Dock

Rumex sanguineus, commonly known as wood dock or red-veined dock, is a hardy herbaceous perennial in the Polygonaceae family, native to Europe. It produces bright green leaves with striking dark red stems and veins, growing to around 30 cm tall. The flavour is sharp, tangy and lemony with a smooth, crisp texture. It thrives in partial shade in fertile, well-drained soil with a pH of 5.5–6.8.

Growing

Soak seeds overnight before sowing. Direct-sow seeds 1 cm deep into fertile, well-drained soil once the soil temperature reaches at least 7 °C. Space plants 30 cm apart. Germination occurs in 7–14 days at soil temperatures of 7–23 °C. Choose a partially shaded position; the plant tolerates acidic conditions. Division of established clumps is also an effective propagation method.

Care

Water consistently to keep soil moist but not waterlogged. Apply a balanced fertiliser in the growing period to support vigorous leaf production. Remove flower stalks as they appear to redirect energy into leaf growth and prolong the harvest season. Mulch around the base to retain moisture and suppress weeds.

Harvest

Begin harvesting outer leaves once plants are well established and leaves are of usable size, typically from around 55 days after sowing. Pick outer leaves regularly, leaving the central growing point intact to encourage continuous regrowth. Younger leaves are most tender and flavourful; older leaves become tough and should be composted or used cooked.

In the kitchen

Use young leaves raw as a salad green or baby leaf, or as a garnish for their striking appearance. Older leaves can be wilted into soups, sauces or egg dishes where their lemony tang complements rich flavours. A classic pairing is with cream or fish. The leaves are nutritious, containing vitamins A and C and minerals including calcium, iron and potassium.

Storing

Store freshly harvested leaves unwashed in a sealed bag or airtight container in the refrigerator for up to 5 days. Do not wash until ready to use. Leaves can be blanched and frozen for longer storage, though texture softens on thawing, making them best used cooked from frozen.
