Water Calanthe gustavii thoroughly when the potting medium approaches dryness. Avoid letting it sit in standing water, as this can lead to root rot.

Reduce watering significantly during its dormant period to prevent excess moisture build-up around the roots.

Pruning is generally minimal for Calanthe gustavii. Remove spent flower spikes at the base after blooming ceases.

Old, yellowing leaves can be trimmed away as they naturally senesce to maintain plant health and appearance.

Calanthe gustavii can be propagated by division. Carefully divide overgrown clumps during the repotting process, ensuring each section has several pseudobulbs and healthy roots.

Pot the divisions individually in appropriate orchid mix.

Repot Calanthe gustavii every 2-3 years, or when the potting medium begins to break down. It's best to repot after flowering has finished and before new growth commences, usually in spring.

Use a well-draining orchid bark mix.
