Water regularly, allowing the top 2-3 cm of soil to dry out between waterings. Avoid overwatering, which can lead to root rot, especially in poorly draining soil.

Reduce watering frequency during winter dormancy periods when the plant's growth slows down.

Prune back leggy growth in late spring or early summer to encourage a bushier habit. Remove any dead or damaged foliage as needed throughout the year.

Pinching back the tips can also promote denser growth and more blooms. This helps maintain plant health.

Propagate easily from seed sown directly in the garden or in pots after the last frost. It also readily self-seeds. Division of established clumps in spring or fall is another effective method.

Stem cuttings can also be rooted in moist soil or water.

Repot young plants annually or as needed, typically in spring, when they become root-bound. Choose a pot that is only slightly larger than the current one. Use a well-draining potting mix.

Mature plants can be repotted less frequently, every 2-3 years.
