Watering, pruning, propagation, and repotting details from plant data
Water consistently once the top 2-3 cm of soil has dried out. Avoid overwatering, especially in cooler months, to prevent root rot. Ensure good drainage, as this plant dislikes soggy conditions.
Prune after flowering to maintain a compact shape and remove any spent flower stalks. Light trimming can encourage bushier growth. Remove any dead or damaged foliage at any time of the year.
Propagate by taking basal cuttings in spring or early summer, or by sowing seeds in autumn. Cuttings root relatively easily in a well-draining compost mix. Seed propagation may require stratification.
Repot young plants annually or bi-annually in spring. Mature plants can be left in their pots for longer, repotting only when root-bound. Use a well-draining compost mix and a slightly larger pot.
