Pre-flowering/Mature Vegetative
6-12 months before first bloomsPlant reaches 10-15 inches tall with 6-8 healthy leaves; stem thickens; visible aerial roots develop
Provide 3-4 week cool, dry rest period in fall/winter to initiate flowering. Reduce watering slightly. Maintain bright light. Full-strength orchid fertilizer.
Flowering
4-8 weeks per spike; potential year-round blooming under ideal conditionsUpright inflorescences emerge from leaf axils bearing 15-30 bright orange flowers; blooms last 4-8 weeks; multiple spikes possible
Reduce temperatures slightly (62-78°F) to extend bloom longevity. Avoid moving plant or changing light. Continue light watering. Do not fertilize during bloom.
Post-bloom/Rest
