Water thoroughly when the top 5-7 cm of soil feels dry. Avoid overwatering, as Salvia × lavandulacea prefers well-draining conditions and can be susceptible to root rot.

Reduce watering in winter when the plant is less active to prevent waterlogged roots.

Prune lightly after flowering to maintain a tidy shape and encourage bushier growth. Remove spent flower stalks to prevent self-seeding if desired.

Heavy pruning can be done in early spring before new growth emerges to rejuvenate the plant.

Propagate Salvia × lavandulacea from semi-hardwood cuttings taken in summer. Insert cuttings into a well-draining medium and keep them moist and warm.

Alternatively, it can be grown from seed sown in spring, but germination can be slow and erratic.

Repot young plants annually or biennially in spring. Mature plants can remain in their pots for several years. Use a well-draining potting mix, such as a cactus or succulent blend.

Ensure the new pot has drainage holes to prevent waterlogging.
