Water thoroughly when the potting medium is nearly dry, typically every 7-10 days during the growing season. Reduce watering in winter. Avoid letting the roots sit in water to prevent rot.

Use lukewarm, distilled, or rainwater for best results.

Pruning is generally minimal for Angraecum angustum. Remove any dead or damaged leaves or flower spikes at the base. Sterilize pruning tools to prevent disease transmission.

Avoid cutting healthy growth as it detracts from the plant's natural form.

Propagation is typically done by division of established clumps during repotting. Carefully separate the pseudobulbs, ensuring each division has at least 2-3 healthy pseudobulbs and roots.

Allow the cut surfaces to dry before repotting.

Repot every 2-3 years or when the potting medium breaks down, preferably in spring after flowering. Use a well-draining orchid mix.

Ensure the pot size is only slightly larger than the root ball to avoid overwatering issues.
