Cymbidium Flower Spots: Botrytis Fungus Prevention

Brown Stains on Blossoms—Contagious? Destroy?

Cymbidium white flowers: brown spots like stains, not raised, won't wipe off. Catch? Quarantine?

Botrytis: Wet Flowers + Cool Night

Fungus spores land on water droplets, grow overnight. No cure, only prevention.

Prevent

• Water early, avoid flowers.
• Fan after watering.
• Reduce humidity, increase air movement.
• Favors light colors, especially white.

Spreads if nearby flowers also wet/damp. Remove spotted flowers.
