Water Veronica speciosa regularly, ensuring the soil remains consistently moist but not waterlogged. Allow the top 2-3 cm of soil to dry out between waterings, especially during warmer months.

Reduce watering frequency in winter to prevent root rot. Good drainage is crucial for its health.

Prune Veronica speciosa after flowering to encourage bushier growth and more blooms. Remove spent flower spikes and any dead or leggy stems.

A harder prune can be done in late winter or early spring before new growth begins to shape the plant.

Propagate Veronica speciosa from semi-hardwood cuttings taken in summer. Select healthy shoots, cut them into 10-15 cm lengths, and remove lower leaves.

Insert cuttings into a well-draining rooting medium, keep moist, and place in a warm, bright location with high humidity.

Repot Veronica speciosa every 2-3 years, or when it becomes root-bound. Use a well-draining potting mix, typically a peat-based compost with added grit or perlite.

Choose a pot that is only slightly larger than the current one to avoid overwatering issues.
