Water regularly, allowing the soil to dry slightly between waterings. Ensure good drainage to prevent root rot. During hot, dry periods, increase watering frequency.

Overwatering can lead to fungal diseases and yellowing leaves. Aim for consistently moist, but not waterlogged, soil.

Prune back after flowering to maintain a tidy shape and encourage bushier growth. Deadheading spent flowers will prolong blooming.

In colder climates, cut back to the ground in late autumn or early spring before new growth appears to promote vigor.

Easily propagated from seeds sown in spring or by taking stem cuttings in late spring or early summer. Cuttings root readily in moist, well-drained soil or perlite.

Seedlings can be transplanted when they are large enough to handle.

Repot young plants annually in spring to ensure adequate space for root development. Mature plants can be repotted every 2-3 years or when they become root-bound.

Use a well-draining potting mix and a pot slightly larger than the current one.
