Cymbidium orchid roots are a crucial aspect of these beautiful flowering plants. Proper care and maintenance of the roots can ensure your Cymbidium thrives and produces stunning blooms. In this article, we’ll dive deep into the key considerations for watering, root health, and propagation.
Watering After Repotting
After repotting your Cymbidium orchid, it is essential to avoid watering the media for at least three days. This allows any cuts or breaks in the roots to callous and prevent rotting. This ensures the roots heal properly before introducing water, which can lead to root rot if not done correctly.
Signs of Healthy Roots
Healthy Cymbidium roots are typically white or light-colored and firm. They should be free of rot and fungal infections. To promote healthy root growth, ensure the potting medium is well-draining and not too dense, as this can cause root rot.
Removing Old, Leafless Back Bulbs
Old, leafless back bulbs can be removed from your Cymbidium orchid without harming the plant. These back bulbs can be used to propagate new plants by washing and drying them, then setting them in a mixture of leaf mold, sand, and potting soil. Keep them moist in a warm, shady spot, and you may see new plantlets emerge in five or six weeks.
Common Contaminants and Chemicals
Cymbidium orchid roots can be susceptible to the following contaminants and chemicals:
| Contaminant/Chemical | Impact |
|---|---|
| Fungal infections | Overwatering and poor drainage can lead to fungal infections, which can cause root rot. |
| Mineral buildup | Using tap water with high mineral content can lead to mineral buildup in the potting medium, requiring more frequent repotting. |
| Pesticides and insecticides | Chemicals used to control pests can harm the roots if not used properly. |
Dealing with Contaminants and Chemicals
To deal with these contaminants and chemicals, follow these guidelines:
- Use clean water: Use rainwater, distilled water, or reverse osmosis water to minimize mineral buildup.
- Sterilize tools: Sterilize all cutting and potting instruments to prevent the transfer of diseases.
- Monitor watering: Avoid overwatering and ensure good drainage to prevent fungal infections.

Troubleshooting Tips
- Check for root rot: Regularly inspect the roots for signs of rot and fungal infections.
- Adjust watering: Adjust watering schedules based on the season and growth stage of the plant.
- Monitor for pests: Regularly inspect the plant for signs of pests like spider mites.
Decoration Guide
Cymbidium orchids can be beautifully displayed in a bright room with indirect sunlight. They prefer cooler conditions, making them ideal for winter greenhouses or indoor spaces.
Fertilization
Fertilize your Cymbidium orchid regularly, using a balanced, water-soluble fertilizer. You can also use a fertilizer specifically formulated for orchids, such as Green Jungle Orchid Food.
Sunlight and Temperature
Cymbidium orchids prefer bright, indirect sunlight and cooler temperatures, ranging from 10°C to 24°C (50°F to 75°F).
Potting Mix
Use a light, porous potting mix that can hold moisture while draining thoroughly upon watering. New Zealand Sphagnum Moss or Traditional Orchid Bark Mix are recommended.
