Growing Conditions

☀️
Sun: Bright, indirect light; 2,000-3,000 foot-candles recommended (east or west-facing windowsill, or orchid growing lights)
💧
Water: Water thoroughly when potting media approaches dryness, typically once weekly during growing season; reduce frequency in winter dormancy. Ensure excellent drainage to prevent root rot.
📏
Spacing: 12-18 inches between plants to allow air circulation inches
📅
Days to maturity: 3-5 years from propagation to first flowering
🌱
Planting depth: Pseudobulbs should sit at soil surface; mount on bark or pot in shallow orchid containers

Soil

Type: Well-draining orchid bark mix (fir bark, sphagnum moss, charcoal)
pH: Not critical; orchids are epiphytic and thrive in coarse, aerated media
Amendments:
Horticultural charcoal for drainage Perlite or expanded clay pellets Premium orchid potting mix

Growth Stages

1

New Growth

4-6 weeks

Emergence of new pseudobulbs and leaves from the rhizome, typically in spring and summer

Provide consistent warmth (70-80°F), humidity (60-70%), and regular watering; apply diluted orchid fertilizer weekly

2

Vegetative Development

6-8 weeks

Pseudobulbs enlarge and mature leaves expand; plant builds energy reserves for flowering

Maintain bright light and warm conditions; continue regular watering and feeding; ensure good air circulation

3

Dormancy/Rest Period

8-12 weeks

Growth slows in fall and early winter; pseudobulbs mature and harden off

Reduce watering frequency but maintain humidity; provide cooler nights (55-65°F) to trigger flowering; reduce fertilizer

4

Flowering

2-3 months (winter to early spring)

Inflorescences emerge from base of mature pseudobulbs with 3-5 fragrant, long-lasting flowers per spike

Maintain cool nights, bright light, and moderate humidity; avoid moving plant; water carefully around blooms

5

Post-Bloom

2-4 weeks

Flowers fade and drop; plant enters growth phase or brief rest

Resume warmer temperatures and increased watering; begin regular fertilizing to support new growth

Harvest Tips

Cut flower spikes at the base when the first bloom opens for display in water; spikes can produce secondary blooms if left on plant. Flowers typically last 3-4 weeks in a vase.
