Water Siberian Larkspur regularly, especially during dry spells, ensuring the soil remains consistently moist but not waterlogged. Allow the top 2-3 cm of soil to dry out slightly between waterings to prevent root rot.

Overwatering can be detrimental.

Deadhead spent flowers regularly to promote continuous blooming and prevent seed formation. In autumn, after flowering has ceased, cut back the plants to the ground.

This tidies the plant and prepares it for winter dormancy.

Siberian Larkspur can be propagated by seed sown in autumn or early spring. It can also be divided in early spring or late summer. Cuttings can be taken in late spring, but this method is less common.

Repotting is generally not necessary for established plants as Siberian Larkspur prefers to be undisturbed. If growing in a container, repot every 2-3 years in early spring into a slightly larger pot with fresh, well-draining potting mix.
