Why Dendrobiums Won't Bloom: The Missing Rest Period

The Problem: Continuous Growth, No Flowers

Your Dendrobiums produce abundant leaves and canes but no blooms. Cause: no dry rest period. In nature, these orchids experience a seasonal drought that triggers flowering.

Solution: Simulate the Dry Season

• Stop fertilizing.
• Reduce watering to occasional misting (just prevent cane shriveling).
• Canes should turn straw-colored; deep green = too much water/low light.
• Increase light—yellow-green leaves indicate blooming-level light.
• Resume water/fertilizer when new growth emerges (end of rest period).

Your Current Conditions

Office warmth (70°F), fluorescent lights, constant watering/feeding = perpetual "wet season." The plant never gets the signal to bloom.
