Overwatering can lead to root rot.

Watering, pruning, propagation, and repotting details from plant data
Keep the soil consistently moist but not waterlogged. Water thoroughly when the top inch of soil feels dry. Reduce watering slightly in cooler months, but never allow the soil to dry out completely.
Overwatering can lead to root rot.
Prune lightly after flowering to encourage bushier growth and more blooms. Remove spent flower stalks and any dead or yellowing leaves.
Pinching back the tips of new shoots can also promote a more compact and attractive shape.
Propagate from stem cuttings taken in spring or early summer. Use a rooting hormone and plant in a well-draining potting mix. Keep the cuttings moist and warm, ideally with bottom heat, until roots have formed.
This method is relatively easy.
Repot every 1-2 years in spring when the plant becomes root-bound. Use a slightly larger pot with good drainage. Choose a well-draining potting mix, such as a peat-based mix amended with perlite.
Handle the roots gently during repotting.
