Cypripedium (Lady Slipper) Spike Dieback: Normal Cycle and Next Year's Bloom

What You're Seeing Is Normal

Spike and buds turning reddish-brown after 2.5 months and 6 flowers = natural end of bloom cycle. Cut the spike off low, near the leaves.

Care for Next Year's Bloom

• Water: Keep evenly moist—never bone dry, never soggy.
• Fertilize: Weak balanced fertilizer occasionally during growth.
• Light: Bright shade + several hours morning sun.
• Temperature: Normal home temps (65-75°F) most of year.
• Bloom trigger: Cool nights ~50°F (10°C) for a month in late fall/early winter initiates next spike.

Growth Cycle

New growth starts now through fall. Rest period in late fall (reduce water slightly, but don't stop). Spike emerges winter, blooms spring.

Key Difference from Tropical Orchids

Cypripediums are often temperate/terrestrial—they need that cool period. Without it, they may grow beautifully but never bloom.
