Water:
Rehmannia prefers consistently moist soil, needing weekly watering to prevent waterlogging. As an herbaceous perennial, its moisture requirements increase during the growing season to support healthy foliage and blooms.
Propagation:
Rehmannia propagates via seeds, division, or cuttings. Seeds may need stratification. Division is easiest in spring. Maintain high humidity for cuttings. Essential conditions include warm temperatures (20°C), indirect light, and well-draining soil. Avoid overwatering. Follow steps for successful propagation and transplant after establishment.
