Cymbidium Seedlings with Spots/Streaks: Virus Fears and Supplier Action

68mm Pot Seedlings, 3 Months, All Affected

Black mottled spots → yellow spots on young leaves/stems → yellow stripes. Roots healthy. All seedlings from same supplier affected.

Differential Diagnosis

• Black mottled spots: Monitor—if enlarge = infection (fungal/bacterial).
• Yellow spots on leaf tops: Sudden bright light = sunburn (may turn brown/black).
• Yellow stripes: Mineral deficiency (Mg, Fe, others).

Critical: All Plants Affected = Supplier Issue

Systemic problem across batch suggests nursery-origin issue. Contact supplier immediately with photos/description.

Virus Reality Check

• Incurable in plants.
• Spreads via unsterilized tools (primary), leaf contact (secondary).
• Sterilize tools between every plant (flame/bleach).

Action Items

1. Call supplier—document everything.
2. Isolate from other plants.
3. Sterilize tools religiously.
4. Monitor spot progression.

Don't panic—diagnose, document, communicate.
