Growing Conditions

☀️

Sun: Bright, indirect light; 2,000-3,000 foot-candles recommended. Avoid direct afternoon sun which can scorch leaves; dappled or filtered light is ideal.

💧

Water: Water thoroughly when the potting medium is nearly dry. Prefers humidity of 60-80%. Water more frequently during growing season (spring-summer) and reduce in winter. Use room-temperature, low-mineral water.

📏

Spacing: Not applicable for single specimens, but allow 6-12 inches between multiple plants for air circulation inches

📅

Days to maturity: 3-5 years from young plantlet to first flowering; mature plants rebloom annually

🌱

Planting depth: Plant at the same depth as received; the base of the pseudobulbs should be at or slightly above the medium surface

Soil

Type: Well-draining orchid bark mix (fir bark, sphagnum moss, perlite, or specialized epiphytic orchid substrate)

pH: 5.5-6.5

Amendments:

Sphagnum moss for moisture retention Perlite or cork for drainage Charcoal to prevent root rot Orchid-specific slow-release fertilizer

Growth Stages

Establishment (newly potted)

4-8 weeks

Plant acclimating to new pot with minimal active growth. Roots and pseudobulbs intact but plant may not produce new growth for several weeks.

Water sparingly until new roots emerge. Maintain bright, indirect light and high humidity. Avoid fertilizing for 4-6 weeks.

Vegetative Growth

6-8 months

New pseudobulbs and leaves develop. Plant produces multiple new shoots and gradually increases in size.

Water regularly when medium is nearly dry. Provide bright, indirect light. Fertilize weekly at half-strength with orchid fertilizer (balanced or high-nitrogen). Maintain 60-80% humidity.

Pre-flowering/Rest Period

4-8 weeks

Growth slows as mature pseudobulbs develop. Plant accumulates energy for blooming.

Provide a slight temperature drop (5-10°F cooler than growing season) to trigger flowering. Reduce watering slightly. Continue bright light and maintain humidity. Reduce nitrogen; use high-phosphorus fertilizer.

Flowering

4-6 weeks of bloom

Inflorescences emerge from the base of pseudobulbs, producing 3-8 delicate white flowers with purple-red markings and a sweet fragrance.

Do not move the plant during bud development or blooms may drop. Maintain consistent temperature (65-75°F), humidity, and light. Water carefully to avoid wetting flowers. Discontinue fertilizing once flowers open.

Post-flowering Rest

4-6 weeks

Flowers fade and drop. Plant enters a period of reduced metabolic activity before next growth cycle.

Reduce watering frequency but keep medium lightly moist. Maintain bright light and good air circulation. Resume light fertilizing (balanced formula) after 2-3 weeks.

Common Pests

Inspect regularly; remove with alcohol-soaked cotton swab. Spray with insecticidal soap or neem oil if infestation occurs. Repeat every 7-10 days.
Scrape off manually with soft brush. Treat with horticultural oil or insecticidal soap. May require multiple applications.
Increase humidity to 70%+ as mites prefer dry conditions. Mist foliage regularly. Use miticide or neem oil spray if severe.
Ensure well-draining medium and never let roots sit in water. Remove affected roots with sterile tools. Repot in fresh medium. Reduce watering frequency.
Improve air circulation. Remove affected leaves. Avoid overhead watering. Apply copper fungicide if widespread.
