Quick Grow Facts
Plant: Culinary rosemary, Salvia rosmarinus (syn. Rosmarinus officinalis); SimplyHerbs programme. Evergreen, branching, woody perennial.
Seed form: Multi-seed pellets; sow one whole pellet per cell or small pot. Several seedlings may emerge together. Pack sizes count pellets, not guaranteed plants.
Sowing: Use a fine, free-draining seed mix; cover the whole pellet lightly, provide light and keep the sowing layer evenly moist while the water-soluble coating breaks down. Do not waterlog the tray.
Germination: Aim for a 20–22°C growing medium. Emergence can vary; watch moisture and light rather than a fixed day count.
Position and spacing: Full sun and excellent drainage. Give young garden plants about 30–46 cm of space and allow more room as they grow, especially in humid conditions.
Growth form: Evergreen, branching herb that becomes woody with age. A maintained young herb pot and a mature shrub need different amounts of room.
When to start: Start under protection in suitable temperatures; harden seedlings off and plant outdoors in a mild period after local frost risk.
Picking: Take only a few soft tips from a well-rooted plant that is actively replacing growth. Leave most foliage on young plants; use plant readiness rather than a fixed harvest day.
Store unused pellets airtight, cool, dark and dry. Sow pellets for growing plants, not for eating or sprouting. Follow the label of any product used on edible herbs, including its harvest interval.
Growing Notes
- Keep the pellet moist through germination, then gradually allow the surface to dry slightly between waterings. Never leave roots standing in water.
- Move on healthy rooted plugs without tearing apart their seedling cluster; thin surplus stems gently if crowding develops.
- Harden seedlings off gradually. Protect young plants from frost, harsh wind and sudden heat.
- Trim leafy tips once established and lightly shape after flowering. Avoid cutting into bare old wood.
Garden and Kitchen Uses
Enjoy aromatic foliage in a sunny container or free-draining bed. Pick sparingly while plants are young; use clean, washed sprigs in cooked vegetables, roasts and bread, observing any treatment or pesticide harvest restrictions.
