Growth Stages

Stage	BBCH	Notes
Sowing and germination	0	Sow indoors in spring or outdoors mid-spring to early summer, about 1cm deep, in fertile moisture-retentive soil in sun or partial shade; germination can take several weeks (RHS).
Thinning and establishment	1	Thin seedlings to 20-30cm apart and water regularly through dry spells until plants establish (RHS).
Leaf harvest	4	Pick young leaves from the first spring growth right through into autumn; frequent picking encourages tender new growth. Leaves can be ready within about 8 weeks of sowing (RHS).
Flower removal and clump maintenance	5	Snip out flower stems as they appear to keep leaf production going and prevent self-seeding; mulch each year in late winter or early spring, and divide congested clumps every four or five years (RHS).

Harvest & Storage

When to pick: Young sorrel leaves can be harvested from when new growth starts in spring right through into autumn. Regular picking produces tender leaves; older foliage becomes tough and bitter (RHS)

Storage

Best used fresh; remove seed stalks that emerge to keep plant productive (UMN)

Pests

Slugs

Gastropoda (slugs, various spp.)

Snails

What the research guides add

Sorrel is a perennial leaf herb, and the Missouri Botanical Garden names the milder alternative that many cooks prefer.

• A perennial herb grown mainly for its leaves, which are used in salads and cooking; plants reach about 2 feet tall with basal clumps of 4 to 6 inch arrowhead-shaped leaves. (Missouri Botanical Garden)
• The leaves have a tangy, acidic, sour-lemony flavour and the youngest leaves have the best flavour. (Missouri Botanical Garden)
• It self-seeds and can spread in the garden. Many food experts prefer French sorrel (Rumex scutatus) for culinary purposes. (Missouri Botanical Garden)
