Growth Stages

1

Dormancy/Winter Rest

October-December

Plant enters dormancy in fall-winter with minimal growth. Pseudobulbs are plump and mature. Flower buds begin forming at base of new growth.

Reduce watering significantly. Maintain cooler temperatures (55-60°F nights). Provide bright light. Lower humidity slightly. No fertilizing required.

2

Flowering

December-February

Arching inflorescences emerge from base of pseudobulbs bearing 3-6 pure white, fragrant flowers with yellow and orange lip markings. Blooms are long-lasting, 4-6 weeks.

Maintain cool temperatures (50-65°F) to extend bloom duration. Provide high humidity and bright indirect light. Water moderately. No fertilizing; avoid misting flowers.

3

New Growth/Spring

February-April

After flowering, new growth emerges with developing shoots and leaves. Fresh pseudobulbs begin forming. Plant becomes more actively metabolic.

Resume normal watering. Increase temperature to 65-75°F. Begin balanced fertilizing (1/4 strength weekly). Increase humidity to 60-70%. Provide bright light.

4

Active Growing Season

April-August

Vigorous growth of new pseudobulbs and foliage. Multiple new shoots developing. Plant size expands. Leaves are green and turgid.

Maintain consistent moisture without waterlogging. Water every 5-7 days. Apply orchid fertilizer (dilute) weekly. Maintain warm temperatures (70-80°F day, 60-65°F night). High humidity essential.

5

Maturation/Hardening

August-October

New pseudobulbs mature and harden. Growth slows naturally. Foliage fully developed. Buds begin forming for next season.

Gradually reduce watering as growth slows. Reduce fertilizer frequency. Provide bright light. Allow cooler fall temperatures (nights 55-60°F). Maintain humidity.

Companion Planting

Plant with:

Avoid planting near:

Ethylene-producing plants (ripe fruits, vegetables) Directly below flowering plants that drip water Heaters or air conditioning vents (causes drying) Pesticide-treated plants Overly wet-growing plants that create stagnant humidity

Common Pests

  • Increase humidity to 60-70%; spray with water or neem oil; isolate infested plant; repeat every 7-10 days

  • Remove with cotton swab dipped in rubbing alcohol; spray with horticultural oil or insecticidal soap; repeat weekly until clear

  • Manual removal with soft brush; apply horticultural oil or neem oil spray; quarantine affected plant

  • Spray with water to dislodge; apply insecticidal soap or neem oil; increase air circulation

  • and (from overwatering)

    Repot into fresh, well-draining medium; trim dead roots; reduce watering frequency; ensure excellent air circulation

Harvest Tips

Cut flower sprays at base of inflorescence using sterile scissors after buds have fully opened. Leave inflorescence on plant if not harvesting for cut flowers, as it may rebloom. Expect annual flowering in winter months once plant is mature. Flowers last 4-6 weeks on the plant.

Fun Facts

  • 🌱 Coelogyne mooreana is named after orchid hunter and horticulturist Fred Sander's nephew Moore, reflecting the Victorian era's obsession with orchid collecting and naming conventions.
  • 🌱 This orchid naturally grows as an epiphyte on trees in cool, misty Himalayan forests at elevations of 5,000-8,000 feet, which is why it requires cool winter rest and high humidity to thrive in cultivation.
  • 🌱 The pure white flowers with golden-yellow and orange lip markings are highly fragrant specifically during morning and evening hours, releasing their strongest honey-scent to attract specific pollinator species in their native habitat.
