Water regularly, ensuring the soil remains consistently moist but not waterlogged. Allow the top few centimeters of soil to dry out between waterings, especially during warmer months.

Reduce watering frequency in cooler periods to prevent root rot.

Prune to maintain shape and encourage bushier growth. Pinch back the tips of young plants to promote branching. Remove spent flower stalks to prevent self-seeding and to redirect energy back into the plant's development.

Easily propagated from seeds sown directly into the soil after the last frost, or started indoors a few weeks prior. Cuttings can also be taken from healthy stems and rooted in moist soil or water.

Repot young plants annually in spring as they outgrow their containers. Mature plants can be repotted every 2-3 years. Use a well-draining potting mix and choose a pot slightly larger than the current one.
