Phalaenopsis Keiki and Mother Plant: Repotting Both for UK Winter

Your UK Phalaenopsis has a mature keiki (3 leaves, 2+ inch roots) on an old spike and the mother needs repotting. Here's how to handle both in autumn.

Keiki Removal (Ready Now)

1. Twist gently at attachment point; cut if resistant
2. Pot in 3-inch pot with fine bark
3. High humidity (bag/dome) 2-3 weeks
4. Bright shade, warm (18-22°C)

Mother Plant Repotting (Anytime for Phalaenopsis)

• UK autumn = fine to repot (no distinct rest period)
• Fresh bark, plastic pot with holes
• Remove shriveled/brown roots (dehydrated, not rot)
• Soak long roots 30 min for flexibility
• Rotate slowly into pot to guide roots down
• Leave flower spike; stake after repotting

Shriveled Root Clarification

Brown, shriveled roots = dehydrated (cork layer formed), not rotten. They can produce new root branches when moisture returns. Keep them if firm inside.

UK Winter Care

• Grow lights essential (12-14 hours, 160W+ fluorescent equivalent)
• Minimum 15°C (60°F) nights
• Humidity 50%+ (humidifier/pebble trays)
• Water when bark barely dry (slower in winter)
• East window + supplemental light

Post-Keiki Spike Management

Cut mother's spike just above next lower node after keiki removal. May rebloom or produce another keiki.

Your plants are on track. UK winters demand lights and humidity—provide both for spring blooms.
