Water deeply but infrequently, allowing the soil to dry out completely between waterings. Avoid waterlogging, which can lead to root rot. Established plants are quite drought-tolerant, especially in well-draining soil.

Reduce watering significantly during cooler months to prevent over-saturation.

Deadhead spent flower stalks to encourage further blooming and prevent self-seeding, though some reseeding is common. In autumn, cut back the main plant to the ground once foliage begins to yellow and die back.

Light trimming can maintain shape throughout the growing season.

Salvia sclarea is easily grown from seed, sown in early spring indoors or directly outdoors after the last frost. It can also be propagated by cuttings taken in late spring or early summer.

Division of established clumps in spring is another effective method for propagation.

Young plants may benefit from repotting into a slightly larger container annually. However, Salvia sclarea prefers to be slightly root-bound and is best grown in the ground once established.

Repotting is generally only necessary for container-grown plants that have outgrown their current vessel.
