Dormancy/Rest Period
6-8 weeksPlant enters a semi-dormant state with minimal new growth; occurs for 6-8 weeks after flowering
Reduce watering frequency by 50%; maintain cooler night temperatures (55-60°F); reduce fertilizer; provide bright light but allow more rest
Vegetative Growth
3-4 monthsNew shoots (leads) emerge from the rhizome base; new leaves unfurl; plant builds energy reserves
Increase watering and maintain consistent moisture without waterlogging; feed every 2 weeks with balanced orchid fertilizer (20-20-20); provide maximum bright light and air circulation
Pseudobulb Maturation
4-6 weeksThe new lead develops a swollen pseudobulb (storage organ); leaves mature and harden; plant accumulates carbohydrates for flowering
Continue regular watering and feeding; maintain warm days (75-85°F) and cooler nights (60-65°F); ensure 50-60% humidity; adequate light is critical for flowering initiation
Bud Development & Flowering
2-4 weeks bud development + 4-8 weeks bloomFlower spikes emerge from the base of mature pseudobulbs; buds swell over several weeks; flowers open and last 4-8 weeks
Reduce watering slightly to trigger blooming (some growers allow a brief dry rest); maintain cooler night temperatures (55-65°F) to extend bloom longevity; provide high humidity; support flower spikes with stakes if needed; reduce fertilizer or switch to bloom formula (higher phosphorus)
Post-Bloom & Next Cycle
Varies; 6-8 weeks restFlowers fade and drop; plant may produce a second growth cycle or enter dormancy; resting pseudobulbs support future blooms
Remove spent flower spikes above the base or leave for potential secondary blooms; allow a brief cool, dry rest of 4-6 weeks; then resume regular watering and feeding for the next growth cycle

-
Remove by hand with alcohol-soaked cotton swab; treat with horticultural oil or insecticidal soap; repeat weekly until clear
-
Reduce moisture at substrate surface; use yellow sticky traps; allow bark to dry between waterings; drench with gnat control if needed
-
Isolate infested plants; spray with spinosad or insecticidal soap every 5-7 days; improve air circulation

Fun Facts
