What you need to know to Plant & Grow
St John’s Fire Salvia can be started indoors for early summer colour or direct-sown into warm garden beds in late spring.
-
Indoor Sowing (Recommended for Earlier Blooms): For early summer flowers, start seeds indoors in a sterile soil-less mix in late March. Press seeds gently onto the surface of the medium—leave uncovered, as light is necessary for germination. Maintain a warm temperature of 21 to 24°C throughout the 7 to 14 day germination period.
-
Growing On & Transplanting: Once germinated, grow seedlings on under lights at a cooler temperature of 15°C. Harden off seedlings carefully and transplant outdoors in late May once the danger of spring frost has passed, spacing plants 30 cm apart.
-
Outdoor Direct Sowing: Direct sow outdoors at the end of May. Barely cover seeds with a fine dusting of soil and keep the seedbed consistently moist until seedlings emerge. Thin or transplant to 30 cm apart when seedlings reach 5 cm in height.
-
Garden Care: Choose a fully sunny site with moist, fertile soil. Deadhead spent flower spikes periodically to promote continuous reblooming and maintain a tidy, bushy form throughout the season.
