Water Octomeria doucetteana thoroughly when the substrate is nearly dry. Avoid waterlogging, as this can lead to root rot. During active growth, water more frequently.

Reduce watering in cooler, less active periods to prevent over-saturation and potential fungal issues.

Prune Octomeria doucetteana sparingly, primarily to remove dead, damaged, or diseased pseudobulbs and leaves. Cut back spent flower spikes to encourage reblooming.

Avoid excessive pruning, as this can stress the plant and hinder future growth. Sterilize tools between cuts.

Octomeria doucetteana is typically propagated by division. When the plant becomes overcrowded, carefully divide the rhizome into sections, ensuring each division has at least 3-5 healthy pseudobulbs and roots.

Pot the divisions individually in a suitable orchid mix.

Repot Octomeria doucetteana every 2-3 years, or when the potting medium begins to break down. Choose a pot that allows for adequate root growth without being excessively large.

Use a well-draining orchid bark mix, and gently firm the medium around the roots.
