Dendrobium Not Blooming 15 Months: Rest Period & Light

Dec 2007 Gift, Repotted Post-Bloom, Dry Roots, Healthy Canes—No Flowers

Dendrobium, bloomed at gift. Repotted after. Roots dry/brown, canes/leaves green. 15 months no bloom.

Two Dendrobium Types

• Nobile (cool): Flowers along canes. Need cool, dry rest.
• Phalaenopsis-type (warm): Flowers at cane tips. Need warm, dry rest.

Wrong temp for type = no bloom.

Critical: Dry Rest After Bloom

Little/no water until new shoots at base. Watering during rest = rot or vegetative growth, not flowers.

Repot Only at New Growth

Tight pot, stake canes. No movement.

Light = Bloom Trigger

Brightest spot. Leaves light yellow-green = enough. Dark green = too little.

Follow-Up: Warm Grower Confirmed

Blooms at cane tips. Repotted tight. Water/feed heavily ONLY when new cane growth starts. May be summer. Light water until then.
