Water thoroughly when the top 2-3 cm of soil feels dry. Avoid overwatering, as Echium strictum prefers well-drained conditions and is drought-tolerant once established.

Reduce watering significantly during winter months to prevent root rot.

Prune after flowering to remove spent flower spikes and shape the plant. Cut back the main stem to encourage bushier growth. For older, leggy plants, a harder prune can rejuvenate them.

Remove any dead or damaged stems at any time.

Propagate from seed sown in spring, or from basal cuttings taken in late spring or early summer. Seeds may require stratification. Cuttings should be rooted in a well-draining compost mix in a warm environment.

Repot young plants annually or bi-annually in spring as needed. Mature plants are often best left undisturbed in their pots.

Use a gritty, well-draining compost mix, such as a cactus or succulent mix, to ensure good drainage.
