Water
Water regularly to keep the soil consistently moist but not waterlogged. Allow the top centimeter of soil to dry out between waterings. Reduce watering frequency during winter months to prevent root rot.

Watering, pruning, propagation, and repotting details from plant data
Water regularly to keep the soil consistently moist but not waterlogged. Allow the top centimeter of soil to dry out between waterings. Reduce watering frequency during winter months to prevent root rot.
Prune lightly after flowering to maintain a compact shape and encourage bushier growth. Remove any dead, damaged, or leggy stems. This also helps to promote more abundant flowering.
Propagate from seed sown in spring or from stem cuttings taken in late spring or early summer. Cuttings root easily in moist potting mix and can be transplanted after a few weeks.
Repot every 2-3 years in spring when the plant becomes root-bound. Use a well-draining potting mix and choose a pot only slightly larger than the current one to avoid excessive moisture retention.
