Orchid Pest Control & Common Causes of Dying Plants

Orchids produce beautiful flowers but are also prone to disease and trouble due to their preference for warm, humid environments. Early detection and prompt treatment are key to protecting your plants.

Common Diseases and Problems

Root Rot - **Symptoms**: Roots turn brown to black and become mushy. Leaves yellow and lower leaves drop - **Cause**: Overwatering, deteriorated bark or sphagnum moss - **Treatment**: Trim damaged roots and repot in fresh bark. Use transparent pots to monitor root condition

Bacterial Soft Rot - **Symptoms**: Leaves and stems become water-soaked and rot, emitting a foul odor. Progresses very rapidly - **Cause**: Erwinia bacterial infection entering through wounds during hot, humid conditions - **Treatment**: Promptly remove affected areas and apply fungicide. Disinfect tools with alcohol

Anthracnose - **Symptoms**: Brown to black circular lesions appear on leaves and expand - **Cause**: Fungal infection. Common during rainy season through summer - **Treatment**: Remove diseased leaves and apply fungicide

Scale Insects - **Symptoms**: White cotton or brown granules on leaf undersides and bulbs - **Cause**: Dry indoor environments with poor ventilation - **Treatment**: Remove with ethanol-soaked cotton swabs. Apply insecticide every two weeks

Virus Infection - **Symptoms**: Color breaks and mosaic patterns on petals. Yellow-green mottling also appears on leaves - **Cause**: Orchid viruses transmitted via aphids or unsterilized cutting tools - **Treatment**: No fundamental cure exists. Infected plants should be isolated or disposed of as a principle

Prevention Tips

Water only after confirming that roots have dried. Sterilize pruning tools with alcohol before use. Ensure ventilation to prevent humidity buildup during rainy season through summer.
