Growth Stages

1

New Growth / Vegetative

Spring to mid-summer, 4-5 months

Emerges new pseudobulbs and leaves from the rhizome; foliage is green and upright; no visible flower buds yet

Water regularly and maintain consistent humidity (60-75%); apply balanced orchid fertilizer (20-20-20) weekly at half strength; ensure good air circulation

2

Pre-Flowering

Late summer to early fall, 4-6 weeks

Mature pseudobulbs complete growth; leaf development slows; flower buds begin forming at base of newest pseudobulbs

Gradually reduce watering frequency as growth slows; provide cooler temperatures (55-65°F nights) to trigger blooming; reduce nitrogen, increase phosphorus and potassium fertilizer

3

Flowering

Fall through winter, 8-12 weeks per bloom cycle

Inflorescences emerge and develop multiple buds; flowers open progressively over weeks; blooms are delicate, ruffled, and often fragrant with distinct markings

Maintain cool nights (50-60°F) to extend flower longevity; water at base only to avoid flower spotting; reduce fertilizer; provide bright light without direct sun on blooms; humidity 60-70%

4

Post-Flowering Rest

Winter to early spring, 4-8 weeks

Flowers fade and drop; leaves may yellow slightly; plant enters dormancy phase; new growth begins slowly

Water less frequently (every 7-10 days); keep temperatures cool (55-65°F nights); minimal fertilizing; maintain air circulation; do not remove flower spikes until completely brown

Companion Planting

Plan your garden →

Plant with:

Paphiopedilum (Lady's Slipper Orchid) Oncidium orchids Cymbidium orchids Miltoniopsis orchids Shade-loving ferns (in greenhouse settings)

Avoid planting near:

Ethylene-producing ripening fruit Heating vents and hot air currents Cold drafts from windows Plants requiring constant warm, humid conditions (tropical species) Xeric succulents requiring sparse watering

Common Pests

  • Isolate plant; spray with isopropyl alcohol on cotton swabs; apply horticultural oil spray; repeat weekly for 3-4 weeks

  • Remove by hand with soft brush; spray with neem oil or insecticidal soap; treat every 7-10 days; prune heavily infested leaves

  • Increase humidity and misting; spray with water forcefully to dislodge; use miticide if severe; ensure good air circulation

  • Remove affected leaves; improve air circulation; reduce humidity; avoid wetting foliage; apply copper fungicide if necessary

  • Repot into fresh medium immediately; trim black mushy roots; use well-draining bark mix; allow to dry between waterings; improve drainage
