Growth Stages

Establishment

2-4 weeks

New plant settling into container with visible roots and emerging growth

Keep in bright, indirect light; maintain consistent moisture without waterlogging; ensure good air circulation

Vegetative Growth

6-8 months

New pseudobulbs and leaves developing; plant building foliage and root mass

Apply diluted balanced orchid fertilizer (20-20-20 or similar) weekly during growing season; increase watering frequency

Pre-Flowering (Dormancy Trigger)

4-6 weeks

Growth slows; pseudobulbs mature; plant prepares for dormancy with cooler nights triggering bloom initiation

Provide 10-15°F temperature differential between day and night; reduce watering slightly; lower nitrogen fertilizer (use higher phosphorus/potassium ratio like 6-30-30)

Flowering

4-8 weeks (blooms persist long with proper care)

Spikes emerge and develop large, fragrant purple flowers with ruffled petals and ornate labellum

Maintain bright light and excellent air circulation; support flower spikes with stakes if needed; discontinue high-nitrogen fertilizer; enjoy blooms for 4-8 weeks

Post-Flowering Rest

2-4 weeks

Blooms fade; plant enters brief rest period before resuming growth cycle

Reduce watering slightly; allow brief dry period between waterings; maintain moderate temperatures and light
