Dendrobium Keikis & Flowering: Separate, Repot & Provide Seasonal Cues

A Dendrobium 'Salaya Fancy' produced multiple keikis (offshoots with roots) on its canes, plus a second-generation keiki on a keiki. It hadn't rebloomed since purchase despite weekly watering and fertilizing.

Keiki Separation

1. Wait until keiki roots have green tips and are 1–2 inches long.
2. Gently twist at attachment point on cane—avoid damaging keiki roots.
3. Pot each in small container (just fits roots) with damp bark mix.
4. Keep moist while root tips are green.

Why No Rebloom? Likely Insufficient Light & Missing Rest Period

• Keikis instead of flowers often signal inadequate light for flowering hormones.
• Dendrobiums need a distinct rest period: When new growth matures (canes harden, leaves toughen), stop watering and fertilizing. Mist only 2×/week to keep canes firm.
• Rest typically begins in fall. Cool nights (50–55°F / 10–13°C) + bright light trigger bud formation for winter/spring bloom.

Seasonal Culture Schedule

• Spring/Summer (growth): Heavy water/feed, bright light, can summer outdoors >50°F nights.
• Fall (maturation): Reduce water, stop fertilizer, high light.
• Winter (rest): Minimal misting, cool nights, bright light.
• Late Winter/Spring: Buds appear → resume water/feed.

Light Target

Canes should be light green to yellow-green. Gradually increase to near-full sun (protect from scorching). A west window with afternoon sun works well for many.
