Water thoroughly when the potting mix is almost dry, typically once a week during the growing season. Reduce watering significantly in winter, allowing the substrate to dry out more between waterings.

Ensure good drainage to prevent root rot. Overwatering is a common mistake.

Pruning is generally minimal for Octomeria minor. Remove any dead or yellowing leaves and spent flower spikes at the base. This helps maintain the plant's appearance and directs energy towards new growth.

Avoid cutting healthy green leaves.

Propagation is typically done by division. When the plant outgrows its pot, carefully divide the pseudobulbs, ensuring each section has at least a few pseudobulbs and roots.

Allow the divisions to callus over for a few days before repotting.

Repot Octomeria minor every two to three years or when it outgrows its container. Use a well-draining orchid mix, such as bark chips and perlite.

Repot after flowering or at the beginning of the growing season to minimize stress.
