Care tips
It prefers full sun to partial shade and deep, well-drained soils rich in organic matter for proper root development. It requires regular watering to keep the substrate moist, especially during dry periods, but avoid waterlogging. A common mistake is not harvesting the roots before the plant flowers in its second year, as they become fibrous and bitter afterwards.
