Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the potting medium is nearly dry, typically once or twice a week during active growth. Reduce watering in cooler, dormant periods to prevent root rot.
Ensure good drainage to avoid waterlogged conditions which this orchid detests.
Pruning of Grammatophyllum speciosum primarily involves removing spent flower spikes and any dead or damaged pseudobulbs or leaves. This promotes air circulation and prevents disease.
Cut back cleanly to the base of the affected part.
Propagation is typically achieved through division of mature, overgrown clumps. Carefully separate the pseudobulbs, ensuring each division has at least 2-3 healthy pseudobulbs and some roots.
Allow cuts to callus before repotting.
Repot this orchid every 2-3 years, or when the potting medium begins to break down. Use a coarse, well-draining orchid mix. Repot after flowering, when new root growth is evident.
Ensure the pot size is appropriate for the root mass.
