Sow seeds from March to April in pots or seedling trays, spreading them evenly on the surface of moist compost, a light sprinkle of soil is all that’s needed to gently cover the seeds.

Once your seeds are sown, place the pots or trays in a warm, controlled environment such as a greenhouse or propagator, maintaining a consistent temperature between 20–22°C. This warm, humid environment will encourage the seeds to germinate.

Seedlings typically take 15-21 days to appear. During this time, monitor the compost to keep it moist, but avoid overwatering, which can cause the seeds to rot.

Once your seedlings are established in pots/seedling trays, transplant them into larger pots to accommodate their growth. From end of May gradually acclimate them to cooler conditions by hardening them off over 7-10 days, allowing the plants to adjust to outdoor conditions. Before planting them outside, ensure the soil is sandy, well-drained, and the site receives full sun. Pinch out growing tip to encourage new bushy growth. Deadhead spent flowers if you prefer to prevent self-seeding. Avoid pruning old stems until new growth begins to appear in the spring. The best time to divide perennial Salvias is early spring, before new growth starts to emerge.
