Water thoroughly when the potting medium is nearly dry, typically once every 7-10 days. Avoid waterlogging, as this can lead to root rot. Reduce watering slightly during cooler, dormant periods.

Ensure good air circulation around the roots to promote drying.

Pruning is minimal for Angraecum crassum. Remove spent flower spikes at the base once blooming is complete to direct energy into new growth. Trim away any yellowed or dead leaves as needed.

Avoid cutting healthy, green foliage.

Propagation is primarily achieved through division of mature plants that have developed multiple pseudobulbs.

Carefully separate the plant using a sterile knife, ensuring each division has at least three pseudobulbs and some healthy roots. Allow the cuts to air dry before repotting.

Repot Angraecum crassum every 2-3 years, or when the potting medium begins to break down. Use a well-draining orchid mix, such as bark or charcoal.

Repot after flowering or at the beginning of new growth to minimize stress on the plant.
