Water Jumellea arachnantha thoroughly when the potting medium is nearly dry. Avoid overwatering, as this can lead to root rot. Reduce watering frequency during cooler months.

Ensure good drainage to prevent waterlogged conditions, which are detrimental to this orchid species.

Pruning for Jumellea arachnantha is generally minimal. Remove spent flower spikes at their base once blooming has finished.

Trim any dead or damaged leaves or roots as needed to maintain plant health and encourage new growth. Sterilize pruning tools to prevent disease transmission.

Propagation of Jumellea arachnantha is typically done by division of mature pseudobulbs during repotting. Ensure each division has at least three healthy pseudobulbs and some roots.

Allow cut surfaces to callus for a day before repotting into a suitable orchid mix.

Repot Jumellea arachnantha every 2-3 years, or when the potting medium begins to break down or the plant outgrows its container. This is best done after flowering.

Use a well-draining orchid mix, such as bark and sphagnum moss, and a pot that allows for good air circulation.
