Water Nemesia floribunda regularly, keeping the soil consistently moist but not waterlogged. Allow the top centimeter of soil to dry out slightly between waterings, especially during warm weather.

Reduce watering in cooler months when the plant's growth slows down. Ensure good drainage to prevent root rot.

Pinch back the tips of young Nemesia floribunda plants to encourage bushier growth. Deadhead spent flowers regularly to promote continuous blooming and prevent the plant from setting seed.

Light pruning can also be done to maintain shape and remove any leggy or damaged stems.

Nemesia floribunda is easily propagated from seeds sown in early spring or late autumn. Seeds can be sown directly into the garden or started indoors a few weeks before the last frost.

They germinate best in temperatures between 18-24°C. Cuttings can also be taken from healthy stems in late spring or early summer.

Repot Nemesia floribunda when it becomes root-bound, typically every one to two years. Choose a pot that is only slightly larger than the current one, ensuring it has adequate drainage holes.

Use a well-draining potting mix. Repotting is best done in spring before active growth begins.
