pH: 6.0-7.0
Amendments:
Sphagnum moss Perlite or pumice for drainage Charcoal to prevent bacterial growth Bark chips for aeration

Growth Stages

1

New Growth / Vegetative

4-6 months

Emergence of new shoots and pseudobulbs from the rhizome; leaves unfold progressively and develop mature coloration

Maintain consistent warmth (65-75°F), provide bright light, increase watering and humidity; apply balanced fertilizer weekly at half-strength

2

Maturation

2-4 months

Pseudobulbs reach full size and harden off; new leaves mature completely; plant builds energy reserves

Maintain warm temperatures, provide excellent drainage, continue fertilizing but gradually reduce frequency; ensure good air movement

3

Flowering Initiation

4-8 weeks

Flower spike emerges from base of mature pseudobulb; spike elongates and develops buds along its length

Provide slight temperature drop (60-70°F nights optimal for bud development); reduce nitrogen fertilizer, increase phosphorus and potassium; maintain consistent watering

4

Flowering

6-12 weeks (successive blooms)

Blooms open progressively, displaying large fragrant magenta, purple, or pink flowers with contrasting lip; blooms may last 2-4 weeks per flower

Maintain 60-75°F temperatures, bright light, and good air circulation; avoid overhead watering; do not move plant frequently; reduce fertilizer

5

Post-Flowering / Rest

4-8 weeks

Flowers fade and drop; plant enters a brief rest period before resuming new growth cycles

Reduce watering slightly (but do not allow drying out); maintain temperatures around 60-65°F nights; pause fertilizing for 4-6 weeks; prepare for next growth cycle

Companion Planting

Plant with:

Avoid planting near:

Fruit-ripening plants (ethylene gas damages flowers) Heavily scented flowers that may compete olfactorily Plants requiring constantly wet medium (root rot risk)

Common Pests

  • Increase humidity to 60-70%, spray with water mist, apply neem oil or insecticidal soap, ensure good air circulation

  • Remove with rubbing alcohol on cotton swab, spray with insecticidal soap or neem oil, inspect new plants before introducing to collection

  • Manual removal with brush, apply horticultural oil or neem oil, repeat treatment every 2 weeks until resolved

  • and (Pythium, Phytophthora)

    Improve air circulation, reduce overhead watering, remove affected tissue, repot in fresh medium if roots are affected, apply fungicide if severe

  • Remove affected tissue with sterile tools, improve drainage and air circulation, avoid overhead watering, apply copper-based fungicide
