Water regularly, especially during dry periods, ensuring the soil remains consistently moist but not waterlogged. Allow the top inch of soil to dry out slightly between waterings.

Reduce watering frequency in cooler months when growth slows down. Overwatering can lead to root rot.

Prune lightly after the main flowering period to encourage bushier growth and potentially a second bloom. Remove any dead, damaged, or leggy stems.

For climbing varieties, you can prune to control size and shape as needed throughout the growing season.

Easily propagated from seeds sown directly outdoors after the last frost, or started indoors 4-6 weeks prior. Seeds can also be sown in autumn for overwintering in milder climates.

Cuttings can be taken from softwood in early summer.

Young plants may need repotting annually into slightly larger containers, usually in spring. Mature plants are generally content in their pots and do not require frequent repotting.

Ensure good drainage in the chosen pot to prevent waterlogging.
