Water consistently, especially during dry spells, to maintain evenly moist soil. Allow the top inch of soil to dry out between waterings. Avoid waterlogging, as Veronica montana prefers well-drained conditions.

Reduce watering during winter months when the plant is less active.

Deadhead spent flowers to encourage further blooming and maintain a tidy appearance. Lightly trim the plant after the main flowering period to shape it and prevent it from becoming leggy.

Remove any dead or damaged stems at any time of the year. Avoid heavy pruning.

Veronica montana can be propagated by division of established clumps in spring or autumn. Cuttings can also be taken from semi-ripe shoots in summer. Ensure cuttings are planted in well-draining soil and kept moist.

Divisions should be replanted promptly.

Repot young plants annually or biennially in spring to provide fresh soil and room for root growth. Mature plants may only need repotting every 2-3 years. Use a good quality, well-draining potting mix.

Ensure the new pot has adequate drainage holes.
