Water Verbesina abietifolia regularly, keeping the soil consistently moist but not waterlogged. Allow the top few centimeters of soil to dry out slightly between waterings, especially during drier periods.

Reduce watering in winter when the plant is less active.

Prune Verbesina abietifolia in late winter or early spring before new growth begins. Remove any dead, damaged, or crossing branches to maintain a healthy structure and encourage vigorous flowering.

Deadheading spent flowers can prolong blooming and prevent unwanted seeding.

Propagate Verbesina abietifolia from seeds sown in spring, or by taking semi-hardwood cuttings in summer. Seeds germinate best with consistent moisture and warmth.

Cuttings should be placed in well-draining soil and kept in a humid environment until rooted.

Repot Verbesina abietifolia every 2-3 years, or when the plant becomes root-bound. Use a well-draining potting mix, such as a blend of peat, perlite, and compost.

Repot in spring just as new growth emerges, ensuring the new pot is only slightly larger than the previous one.
