Water consistently to keep the soil evenly moist but not waterlogged. Allow the top inch of soil to dry out slightly between waterings, especially during warmer months.

Reduce watering in winter when the plant's growth slows. Avoid letting the soil become completely dry, as this can stress the plant.

Prune lightly after flowering to maintain shape and remove any dead or damaged stems. Pinching back the tips of young plants can encourage bushier growth.

Avoid heavy pruning, as this plant generally has a naturally graceful habit. Deadheading spent flowers can also improve appearance.

Propagate by division of clumps in spring or by stem cuttings taken in late spring or early summer.

Cuttings should be rooted in a well-draining potting mix, kept consistently moist, and placed in a warm, humid environment. Divisions should be planted at the same depth as they were previously.

Repot every 2-3 years or when the plant becomes root-bound, preferably in early spring before new growth begins. Use a good quality, well-draining potting mix.

Choose a pot that is only slightly larger than the current one to avoid excess moisture retention. Water thoroughly after repotting.
