Water sparingly during the growing season, allowing the substrate to dry out between waterings. Reduce watering significantly during dormancy to prevent root rot.

Ensure good drainage to avoid waterlogged conditions, which are detrimental to this orchid's health.

Pruning is generally not required for Himantoglossum calcaratum. Remove dead or dried leaves at the end of the growing season or after flowering to maintain tidiness.

Avoid cutting healthy foliage as it contributes to the plant's energy reserves.

Propagation is primarily achieved through division of tubers during repotting in late summer or early autumn. Seed propagation is complex and slow, typically undertaken by specialists.

Ensure divisions have at least one healthy tuber and a viable bud.

Repot Himantoglossum calcaratum every 2-3 years, preferably in late summer or early autumn, just as new growth begins. Use a well-draining orchid mix, such as a bark-based substrate with added perlite.

Handle the tubers gently to avoid damage.
