Care
Light exposure
Choose a sunny or partially shaded location to promote plant vigor. It tolerates shaded areas well but will grow less vigorously there. Avoid overly hot spots in Mediterranean climates where it risks water stress.
Watering
Water regularly in spring and summer, keeping the soil moist but not waterlogged. In autumn and winter, reduce watering significantly. Once established, this little sorrel tolerates drought well but appreciates moderate moisture during the growing season.
Soil and preparation
Amend the soil with well-decomposed compost or potting soil before planting. Little sorrel adapts to almost all soil types but hates waterlogging. Ensure proper drainage, especially in heavy clay soil.
Fertilizer
Apply a balanced fertilizer in spring to support growth. A single application is usually sufficient. Avoid excess nitrogen which would promote foliage at the expense of flowering.
Pruning and maintenance
Cut back lightly after flowering to maintain a compact shape and encourage a second flush of growth. Remove spent flowers to extend ornamental interest. The plant self-seeds easily.
Diseases and pests
Rarely affected by diseases in adequate conditions. Watch for rust if humidity is excessive. A few pests may occasionally affect it, but rarely a concern on a well-maintained plant.
Did you know?
Little sorrel is rich in oxalic acid, which gives it its characteristic tart taste; historically, it was traditionally harvested wild and consumed in soups or as a garnish. It was long appreciated in folk medicine for its supposed properties, although excessive consumption is not recommended due to its oxalate content.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
