How to grow salad burnet
Overview
Salad burnet (Sanguisorba minor) is a perennial herb with a mild cucumber flavour, grown for its young leaves in salads and as a garnish. It is drought-tolerant once established and thrives in cool to warm climates without needing rich soil.
Soil Preparation
Salad burnet prefers a free-draining soil with a pH of 6.0–7.0. Add compost or well-rotted manure before planting; avoid heavy clay or waterlogged sites. A light mulch helps retain moisture without causing rot.
Growing Guide
Sow seeds directly in well-drained soil in full sun, spacing 30 cm apart and 5 mm deep. Germination takes 7–14 days; keep soil lightly moist until seedlings appear. Thin to 30 cm apart and cut back old flower stems to encourage fresh leaf growth.
Sowing
Sow seeds 5 mm deep in rows 30 cm apart, or scatter in a seed tray. Germination takes 7–14 days at 15–20°C. Direct sow is best; transplant only if seedlings are well-rooted.
Care
Feed lightly with a balanced liquid fertiliser every 4–6 weeks during active growth. Cut back old, woody stems in early spring to encourage fresh growth. Remove flower heads to prolong leaf production.
Companion Planting
Salad burnet pairs well with other herbs like thyme, oregano, and chives, and with leafy greens such as lettuce and spinach. Avoid planting near aggressive mint or heavy feeders like corn that may compete for water.
Common Pests & Risks
Aphids may cluster on new growth; spray with neem oil or a strong water jet. Slugs and snails can damage young leaves; use iron-based pellets or beer traps. Powdery mildew may appear in humid conditions; improve air circulation and avoid overhead watering.
Harvesting
Harvest young leaves from spring to autumn, picking the outer leaves first. Cut stems at the base when leaves are 10–15 cm long for best flavour; remove flower heads to prolong leaf production.
In the Kitchen
Use fresh young leaves in salads, sandwiches, or as a garnish for soups and fish. The cucumber flavour is best when leaves are picked before flowering; store in a damp paper towel in the fridge for up to 5 days.
Troubleshooting
Yellow leaves: overwatering or poor drainage; reduce watering and improve soil. Brown leaf edges: heat stress or low humidity; provide afternoon shade in hot zones. Stunted growth: lack of nutrients; apply a balanced fertiliser. Flowering too early: cut back flower stalks to prolong leaf harvest. Leaf drop: frost damage; protect with mulch or cloche in severe cold.
