Dormancy
3-4 months (typically November-February)Plant loses leaves and pseudobulbs shrivel by 20-30%. Growth halts completely.
Reduce watering to bare minimum. Maintain temperatures 55-65°F. Provide very little light. This rest period is critical for flowering initiation.
New Growth Emergence
4-6 weeksShoot emerges from base of previous pseudobulb with new leaves unfurling. Fresh roots begin developing.
Gradually increase light and water as growth commences. Resume regular feeding at half strength. Maintain 65-75°F daytime temperatures.
Vegetative Growth
3-4 monthsPseudobulbs enlarge, leaves mature and harden. Plant develops multiple canes with full foliage.
Water abundantly; water every 1-2 days in warm weather. Feed weekly with balanced orchid fertilizer. Provide bright light and good air circulation. Temperatures 70-85°F optimal.
Flowering
2-4 weeks of peak bloomInflorescences emerge from base of mature pseudobulbs, producing spectacular sexually dimorphic flowers. Male and female flowers may differ dramatically in shape, color, and scent.
Reduce watering slightly once flowering begins. Avoid moving plant during bloom. Pollination requires specific insects or hand-pollination; produces large seed pods if pollinated.
Post-Flowering Transition
4-6 weeksFlowers fade and drop. Plant may produce seed pods. Foliage begins to yellow and drop in preparation for dormancy.
Maintain moderate watering. Continue feeding at half strength. Gradually reduce temperatures and light to initiate dormancy. Remove seed pods unless saving seed.

Common Pests
-
Increase humidity and air circulation. Spray with water weekly. Use miticide if severe. Prune affected foliage.
-
Remove with alcohol-soaked cotton swab. Spray with insecticidal soap. Isolate plant from others.
-
Scrape off manually. Apply neem oil or horticultural oil. Repeat every 7-10 days until clear.
-
Improve air circulation dramatically. Reduce watering frequency. Remove affected tissue. Repot in fresh medium if severe. Apply fungicide if needed.
-
Remove affected tissue with sterile tools. Improve air flow. Reduce humidity. Isolate plant. Sterilize cutting tools between cuts.

Harvest Tips
Cut flowers last 5-14 days in a vase depending on species. Harvest when flowers first fully open by cutting the inflorescence at the base with sterile tools. Change vase water every 2-3 days. Display away from ripening fruit (ethylene). Allow flowers to dry on plant naturally for seed production if desired.
Fun Facts
- 🌱 Catasetum flowers are famously sexually dimorphic—male and female flowers on the same plant can look so different that botanists once classified them as separate species. Male flowers are often more colorful and fragrant to attract male orchid bees, while females are less showy.
- 🌱 The plant has a remarkable pollination mechanism: male Catasetum flowers possess a trigger mechanism that catapults pollen masses onto the body of visiting male orchid bees (Euglossini), which collect the waxy fragrance to attract females—a sophisticated manipulation of pollinator behavior.
- 🌱 Catasetum orchids have an extreme deciduous habit unique among orchids—they completely lose their leaves and enter a profound dormancy. This dormant rest is absolutely essential for flowering; without it, the plant will grow vegetatively but produce no flowers.
