Water regularly, keeping the soil consistently moist but not waterlogged. Veronica peregrina thrives in damp conditions, especially during its active growth period.

Reduce watering slightly in cooler months, but avoid letting the soil dry out completely. Proper drainage is essential to prevent root rot.

Pruning is generally not required for Veronica peregrina. If plants become leggy or untidy, you can lightly trim them back after flowering to encourage a more compact form.

Remove any dead or damaged foliage to maintain a healthy appearance and prevent disease spread. Deadheading can sometimes encourage reblooming.

Propagation is easily achieved by seed or cuttings. Sow seeds in early spring either directly outdoors or in a seed tray.

Cuttings can be taken from healthy stems in late spring or early summer and rooted in moist potting mix. This plant readily self-seeds in suitable conditions.

Repotting is typically only necessary if the plant becomes root-bound or needs to be moved to a larger container. This is best done in spring before new growth begins. Use a well-draining potting mix.

Given its often annual or biennial nature, frequent repotting is usually not a concern.
