Watering, pruning, propagation, and repotting details from plant data
Water moderately when the top 2-3 cm of soil feels dry. Avoid overwatering, as this can lead to root rot. Ensure good drainage, especially in containers.
Reduce watering frequency during winter dormancy, allowing the soil to dry out more between waterings.
Deadhead spent flower spikes regularly to encourage continuous blooming and prevent self-seeding. Cut back plants in late autumn or early spring to maintain a tidy appearance and promote vigorous new growth.
Remove any dead or damaged stems at any time.
Easily propagated from seed sown in spring or autumn. Can also be propagated by softwood cuttings taken in late spring or early summer. Layering can also be successful.
Seeds germinate readily in light, well-drained soil.
Young plants may require repotting annually into slightly larger containers in spring. Mature plants are less fussy and can remain in the same pot for 2-3 years. Ensure the new pot has adequate drainage holes.
Use a well-draining potting mix.
