Growth Stages

Dormancy

November-February (3-4 months)

Plant rests underground or in pots with leafless pseudo-bulbs; minimal visible growth

Keep soil dry or barely moist; store in cool location (50-55°F); ensure pseudo-bulbs remain firm and do not shrivel

Growth Emergence

February-March (3-4 weeks)

New growth shoots emerge from pseudo-bulbs; tiny leaves unfurl; plant begins active growth

Increase watering and humidity; begin light feeding with dilute orchid fertilizer (1/4 strength); maintain temperatures around 60-70°F

Vegetative Growth

March-May (8-10 weeks)

Leaves fully develop; plant produces new pseudo-bulbs; foliage expands and matures

Water regularly; fertilize bi-weekly at 1/4 strength; provide bright indirect light; maintain high humidity (50-70%); ensure air circulation

Flowering

April-June (4-6 weeks, flowers last 2-3 weeks each)

Delicate white flowers with patterned labellums emerge directly from pseudo-bulbs; flowers are large and showy

Reduce nitrogen fertilizer; increase phosphorus and potassium to promote blooms; maintain consistent moisture; avoid moving plant during bloom; cooler nights (50-55°F) encourage more flowers

Maturation & Dormancy Preparation

June-October (4-5 months)

Flowers fade; foliage remains green but growth slows; pseudo-bulbs mature and consolidate nutrients

Gradually reduce watering and fertilization; allow foliage to yellow and drop naturally; do not remove pseudo-bulbs; transition to cool, dry storage conditions by fall
