Growing Conditions
Soil
Growth Stages
Dormancy/Rest
October-DecemberPlant sheds leaves in fall and appears bare with exposed pseudobulbs. Minimal growth activity. Lasts approximately 2-3 months.
Reduce watering significantly. Keep temperatures cool (50-60°F nights). Provide bright light. Do not fertilize. This rest period is essential for flowering.
Bud Emergence
January-FebruaryAfter dormancy, flower buds emerge from the base of pseudobulbs before new leaves appear. Buds are visible and swelling.
Gradually increase watering and warmth. Maintain humidity around 60%. Resume light fertilizing. Ensure good air circulation to prevent bud drop.
Flowering
3-6 weeks (February-March typically)Large, showy white flowers with pink or red sepals and lips appear in profusion. Blooms are fragrant and long-lasting.
Maintain consistent moisture without waterlogging. Keep temperatures moderate (55-70°F). Provide bright light. Do not move the plant while in bloom. Apply orchid fertilizer at half strength bi-weekly.
Vegetative Growth
April-SeptemberNew shoots and leaves emerge from the base of pseudobulbs. Plant grows vigorously with formation of new pseudobulbs.
Water regularly but allow slight drying between waterings. Fertilize every 1-2 weeks with balanced orchid fertilizer (equal NPK ratio). Maintain temperatures 65-80°F. Increase humidity to 60-80%.
Maturation
July-SeptemberPseudobulbs fully develop and mature. Plant reaches full size for the season. Growth begins to slow as fall approaches.
Continue regular watering and feeding through summer. Begin reducing water and fertilizer in late summer/early fall. Provide excellent air circulation and brightness.

Fun Facts
- 🌱 Lycaste deppei is named after botanist Johann Friedrich Wilhelm Deppe and produces fragrant flowers that smell distinctly of almonds or cinnamon, with scent strongest in the morning hours.
- 🌱 This orchid is deciduous, naturally shedding all its leaves in the dry season—an unusual trait among orchids—which allows it to survive seasonal drought in its native cloud forest habitat.
- 🌱 Lycaste deppei requires a cool winter rest period with significant temperature drop (10-15°F difference from summer temperatures) to set flower buds; without this dormancy, the plant may not bloom.
