Verbena aristigera prefers consistently moist soil, especially during its active growing season. Water thoroughly when the top 2-3 cm of soil feels dry to the touch. Avoid overwatering, as this can lead to root rot.

Reduce watering slightly in cooler months or when the plant is dormant.

Prune Verbena aristigera to maintain its shape and encourage bushier growth. After flowering, deadhead spent blooms to promote more flowers. A light trim in late spring can also help control size and encourage branching.

Severe pruning can be done in early spring before new growth begins.

Verbena aristigera is typically propagated from seeds sown in spring, or from stem cuttings taken in late spring or early summer.

For cuttings, select healthy stems, remove lower leaves, and dip the cut end in rooting hormone before planting in a well-draining medium. Keep moist and warm.

Repot Verbena aristigera every 1-2 years, or when it becomes root-bound, usually in early spring before active growth commences.

Choose a pot that is one size larger than the current one, ensuring it has adequate drainage holes. Use a well-draining potting mix.
