Getting a Phalaenopsis to Rebloom: Spike Cutting, Cool Nights, and Epsom Salts

Your Phalaenopsis (gifted March 2006) bloomed for months. You cut the spike to 2 inches; it dried to a stick. You water/fertilize but fear it won't rebloom.

Cutting the Spike Was Correct

Removing the spent spike helps the plant recover faster. The dried stub is harmless—trim it shorter if it bothers you.

Rebloom Triggers

• Light: Bright, indirect (east window).
• Temperature: Early fall—2–3 weeks of 55°F nights, days >65°F.
• Epsom salts: During that cool period, water 3x with 1 tsp Epsom salt per quart lukewarm water, then resume normal feeding.
• Repot annually in spring in fresh orchid mix.

Spike Management

When a new spike appears (early winter), stake at 6–8 inches. Handle only above 65°F (spikes are brittle when cool). Don't rotate the plant until buds open—spikes grow toward light.

Patience Pays

Phalaenopsis are reliable rebloomers with seasonal cues. Your plant is healthy—just give it the right signals.
