Water: Keep potting medium consistently moist but not waterlogged. Water thoroughly when top feels slightly dry. Reduce watering slightly in winter. Use room-temperature, preferably distilled or rainwater to avoid mineral salt buildup
📏
Spacing: Not applicable for single specimens; repot to next size up (typically 4-6 inch pot) when plant fills current pot inches
📅
Days to maturity: 3-4 years from seedling to first bloom; established plants bloom annually
🌱
Planting depth: Position plant at same depth as in previous pot; top of pseudobulbs should be at or slightly above soil surface

pH: 5.5-6.5
Amendments:
Orchid bark (medium grade) Sphagnum moss Perlite or pumice for drainage Charcoal to prevent decay

Growth Stages

1

Dormancy/Rest Period

October-December

Plant shows minimal growth; foliage remains healthy but growth slows considerably

Reduce watering slightly and maintain cooler temperatures (55-65°F). This cool period is essential for flower initiation

2

Bud Development

December-January

Flower spike emerges from base of plant; buds begin forming along the spike

Maintain consistent moisture and bright light. Provide humidity around 50-60%. Support the emerging spike with a small stake if needed

3

Flowering

2-4 months (January-April typically)

Single pouched flower blooms, typically with yellow-green petals and burgundy-brown veining. Flower is long-lasting

Maintain stable conditions; avoid moving the plant. Moderate watering and bright indirect light preserve bloom longevity

4

Post-Bloom/Vegetative Growth

April-September

After flowers fade, plant enters active growth phase with new leaf and pseudobulb development

Resume regular watering and feeding schedule. Provide warm, humid conditions (65-75°F, 50-70% humidity). Fertilize biweekly with diluted orchid fertilizer

5

Maturation

May-September

Plant develops new pseudobulbs and foliage; root system expands

Monitor for repotting needs. Maintain consistent watering, humidity, and bright indirect light throughout growing season

Companion Planting

Plan your garden →

Plant with:

Other cool-growing orchid species (Odontoglossum, Masdevallia) Ferns (for humid microclimates) African violets (similar indoor culture requirements)

Avoid planting near:

Cacti and succulents (conflicting moisture needs) Plants requiring hot, dry conditions Fruit-ripening stations (ethylene gas damages orchids)

Common Pests

  • Inspect regularly; remove with alcohol-soaked cotton swab. Treat with neem oil spray or insecticidal soap every 7-10 days

  • Increase humidity; mist foliage regularly. Spray with water or use miticide. Severe infestations may require repeated applications

  • Remove manually with tweezers or soft brush. Apply horticultural oil spray; repeat as needed

  • and (Pythium, Phytophthora, Erwinia species)

    Ensure excellent drainage and air circulation. Remove affected tissue with sterile knife. Reduce watering frequency; allow faster drying. Apply fungicide if widespread
