Verbena officinalis prefers consistently moist soil, especially during dry spells or when establishing. However, it is quite drought-tolerant once mature.

Water deeply when the top few centimeters of soil feel dry to the touch, but avoid waterlogging, which can lead to root rot. Reduce watering frequency in cooler, dormant periods.

Prune Verbena officinalis to encourage bushier growth and more flowers. Deadhead spent flower spikes regularly to prevent self-seeding and extend the blooming period.

A more substantial cutback in late autumn or early spring can rejuvenate the plant and maintain a tidy shape. Remove any dead or damaged stems as needed.

Verbena officinalis can be easily propagated by seed, which can be sown directly outdoors in spring or started indoors. It also readily self-seeds.

Division of mature clumps in spring or autumn is another effective method. Stem cuttings can be taken in late spring or early summer, rooting them in a moist, well-drained medium.

When grown in pots, Verbena officinalis may require repotting every 1-2 years to refresh the soil and provide more space for root growth. Choose a pot that is one size larger than the current one.

Repot in spring before new growth begins, ensuring good drainage. If the plant becomes too large, consider dividing it during repotting.
