Growth Stages

1

Dormancy

October-December

Plant drops leaves; appears nearly bare with visible pseudobulbs

Reduce watering significantly; provide cooler temperatures (55-65°F) and minimal fertilizer; allow rest period of 4-8 weeks

2

Vegetative Growth

January-March

New leaves emerge; pseudobulbs enlarge; plant leafs out with lanceolate foliage

Increase water frequency; provide warm temperatures (65-75°F); fertilize weekly with orchid fertilizer at half strength

3

Bud Formation

March-April

Inflorescence emerges from base of pseudobulb, typically pendulous with multiple flower buds developing

Maintain warm, humid conditions; continue regular watering and feeding; provide bright light; avoid moving plant

4

Flowering

April-June (2-3 months)

Multiple fragrant, waxy flowers in yellow, orange, or cream open sequentially along pendant spikes; flowers last 2-3 weeks each

Maintain humidity and warmth; reduce fertilizer; continue gentle watering; ensure air circulation to prevent fungal issues

5

Post-Flowering & Rest

June-October

Flowers fade; plant gradually transitions to dormancy; foliage begins to yellow and drop

Gradually reduce watering; lower temperatures to 55-65°F; withhold fertilizer; prepare for rest period

Companion Planting

Plan your garden →

Plant with:

Other warm-growing orchids (Cattleyas, Phalaenopsis) Bromeliad companions in mixed orchid collections Mounted ferns Other epiphytic orchids (Oncidium species)
