Water thoroughly when the potting medium is almost dry, typically once a week during active growth.

Reduce watering significantly during the leafless rest period, keeping the pseudobulbs slightly hydrated to prevent shriveling. Avoid waterlogged conditions, which can lead to root rot.

Pruning is generally minimal for Catasetum arietinum. Remove spent flower spikes and any dried or damaged leaves or pseudobulbs. Cut back dead aerial roots if they become unsightly or pose a hazard.

Avoid cutting healthy green tissues.

Propagation is primarily done through division of mature pseudobulbs during repotting. Ensure each division has at least three pseudobulbs and healthy roots.

Allow the cut surface to dry for a day or two before repotting to prevent fungal infections.

Repot every 1-2 years, ideally after flowering when new root growth begins. Use a fast-draining orchid mix, such as bark chips with perlite.

Choose a pot that allows for some growth but is not excessively large to prevent the medium from staying too wet.
