Aspasia principissa prefers consistently moist but not waterlogged conditions. Water thoroughly when the top layer of potting medium feels dry to the touch.

Reduce watering slightly during cooler, dormant periods, allowing the substrate to dry a bit more between waterings. Avoid letting the plant sit in standing water to prevent root rot.

Pruning for Aspasia principissa primarily involves removing spent flower spikes and any dead or damaged leaves or pseudobulbs. Trim away yellowing or brown foliage at the base.

If the plant becomes overgrown, you can divide it during repotting, but avoid excessive pruning to maintain its vigor.

Propagation of Aspasia principissa is best achieved through division. When the plant outgrows its pot, typically every 2-3 years, carefully divide the pseudobulbs.

Ensure each division has at least two to three healthy pseudobulbs and some healthy roots. Replant divisions into appropriate orchid medium.

Repot Aspasia principissa every 2-3 years, or when the potting medium begins to break down. Use a well-draining orchid mix, such as bark chips, perlite, and sphagnum moss.

Repot after flowering or in early spring before new growth begins. Ensure the pot has adequate drainage holes.
