Water
Water thoroughly when the potting medium is nearly dry, reducing frequency during the dormant period. Avoid waterlogged conditions, which can lead to root rot.
Ensure good air circulation to promote drying between waterings.

Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the potting medium is nearly dry, reducing frequency during the dormant period. Avoid waterlogged conditions, which can lead to root rot.
Ensure good air circulation to promote drying between waterings.
Pruning is generally not required for Catasetum atratum. Remove spent flower spikes cleanly at their base. Dead or decaying leaves can be trimmed off with sterile tools, but avoid cutting into healthy pseudobulbs.
Propagation is typically done by division when the plant is overcrowded or during repotting. Ensure each division has at least three healthy pseudobulbs and some roots.
Allow the cut surface to dry slightly before repotting.
Repot every 1-2 years or when the potting medium begins to break down. Use a well-draining orchid mix.
Repot after flowering or when new growth appears, ensuring the pseudobulbs are positioned on the edge of the pot for future expansion.
