Watering, pruning, propagation, and repotting details from plant data
Water Verbena incompta regularly, keeping the soil consistently moist but not waterlogged. Allow the top 2-3 cm of soil to dry out between waterings. Reduce watering during winter dormancy.
Overwatering can lead to root rot, so ensure good drainage.
Prune Verbena incompta in early spring to shape the plant and remove any dead or damaged stems. Deadheading spent flowers throughout the blooming season encourages more blooms.
Light pruning can be done anytime to maintain form.
Verbena incompta can be propagated from seeds sown in spring or by taking stem cuttings in late spring or early summer. Cuttings should be rooted in a well-draining potting mix in a warm location.
Repot Verbena incompta every 1-2 years in spring, or when it becomes root-bound. Use a well-draining potting mix. Choose a pot that is only slightly larger than the current one to avoid overwatering.
