When Will My Phalaenopsis Rebloom? The Short-Day, Cool-Night Formula

Triggering the Next Bloom Cycle

Phalaenopsis that finished flowering in August 2008 should show new spikes by late winter/spring. But you can actively induce blooming.

Natural Triggers

• Short days: 10 hours of light.
• Cool nights: 55°F (13°C) for 2–3 weeks.

Home Method

1. Place in a cool room (55°F nights) for 3 weeks in fall.
2. Water weekly with 1 tsp Epsom salt per quart (magnesium boost).
3. Return to 60°F+ nights.
4. Watch for green/reddish spikes between leaves (roots are gray-green tipped).

Timing

Most hybrids bloom late winter through spring. A large, healthy plant may produce multiple spikes.

Provide the seasonal cues, and your Phalaenopsis will respond on schedule.
