Toothwort prefers consistently moist soil. Water thoroughly when the top centimetre of soil feels dry. Avoid waterlogging, as this can lead to root rot.

In drier periods, especially during active growth, increase watering frequency to maintain optimal soil moisture for this semi-parasitic plant.

Pruning is rarely necessary for Toothwort. Remove any dead or decaying foliage at the end of the growing season to maintain tidiness and prevent potential disease.

Since the plant dies back in winter, this is typically done in late autumn or early winter before the new growth emerges.

Propagation is best achieved by division of rhizomes in early spring before new growth appears. Carefully separate sections of the rhizome, ensuring each piece has at least one bud.

Replant immediately into their desired location, ensuring they are at the correct depth to promote establishment.

Toothwort is not typically grown in pots and is best established in its natural habitat or a woodland garden setting. If it becomes necessary to move a specimen, do so in early spring before flowering.

Handle the root system gently to minimize disturbance, as they are delicate and often attached to host roots.
