Water Brassia arachnoidea thoroughly when the potting medium is nearly dry. Avoid letting the roots sit in standing water, as this can lead to root rot.

Reduce watering slightly during cooler, dormant periods but do not allow the plant to dry out completely. Consistent moisture is key for healthy growth.

Pruning for Brassia arachnoidea primarily involves removing spent flower spikes and any dead or yellowing leaves. Cut back flower spikes to the base once blooming is finished.

Remove dead foliage at the base to maintain air circulation and prevent disease. Sterilize pruning tools between cuts.

Propagation of Brassia arachnoidea is typically done by division.

When the plant has multiple pseudobulbs and has outgrown its pot, carefully divide the rhizome into sections, ensuring each section has at least 3-4 healthy pseudobulbs. Replant the divisions in fresh orchid mix.

Repot Brassia arachnoidea every 2-3 years or when the potting medium has broken down. Choose a pot that allows for root growth but is not excessively large. Use a well-draining orchid bark mix.

Repotting is best done after flowering has finished, typically in the spring.
