Water Verbesina walteri regularly, allowing the soil to dry slightly between waterings. Ensure good drainage to prevent waterlogging, which can lead to root rot.

Reduce watering frequency during cooler months to avoid over-saturation of the soil.

Prune Verbesina walteri in late winter or early spring to remove dead, damaged, or crossing stems. Pinch back young plants to encourage bushier growth.

Deadheading spent flowers throughout the blooming season can promote more blooms.

Propagate Verbesina walteri from seeds sown in spring, or from stem cuttings taken in late spring or early summer. Cuttings root easily in moist, well-draining potting mix.

Seedlings may require protection in their first winter.

Repot Verbesina walteri every 2-3 years, or when the plant becomes root-bound. Use a well-draining potting mix and a pot that is slightly larger than the previous one.

Repotting is best done in spring before new growth begins.
