Veronica nummularia prefers consistently moist soil, especially during its active growth period. Water thoroughly when the top inch of soil feels dry to the touch. Avoid waterlogging, as this can lead to root rot.

Reduce watering slightly in cooler months when growth slows.

Prune Veronica nummularia after flowering to maintain a tidy appearance and encourage bushier growth. Deadhead spent flowers to prevent seed formation. You can also trim back leggy stems to promote denser foliage.

Minor trims can be done at any time.

Veronica nummularia is easily propagated by stem cuttings. Take 4-6 inch cuttings in spring or early summer. Remove lower leaves and insert the cut end into moist potting mix or water.

Roots will form within a few weeks, and they can then be planted out.

Repot Veronica nummularia when it becomes root-bound, typically every 2-3 years. Choose a pot that is slightly larger than the current one. Use a well-draining potting mix.

Repotting is best done in early spring before new growth begins.
