Cymbidium orchids are a popular choice for indoor gardeners due to their stunning flowers and relatively easy care requirements. While these orchids are typically grown in potting mixes, they can also thrive when cultivated in water, a method known as water culture or hydroponic orchid growing. In this article, we’ll explore the key steps and considerations for successfully caring for a Cymbidium orchid in water.
Key Steps
1. Prepare the Orchid
- Remove the orchid from its pot and gently clean the roots.
- Trim away any dead or rotten roots.
- Allow the roots to heal for a day or two before placing them in water.
2. Select a Container
- Use a clear glass container or vase that supports the orchid and allows the roots to stretch out.
- Ensure the container is deep enough to allow the roots to grow without being crowded or curling around the bottom.
3. Watering
- Start by submerging the tips of the roots in a small amount of water and gradually increase the water level as needed.
- Change the water weekly and use a non-urea based fertilizer recommended for orchids. Use a 1/4 strength solution of water/fertilizer mix.
4. Light and Temperature
- Provide bright, indirect light. Cymbidiums require lots of light, but not direct sunlight.
- Maintain temperatures between 40°F and 90°F (4°C and 32°C), with cooler temperatures at night.
Considerations
Nutrition
- Cymbidiums are heavy feeders and require regular fertilization. Use a balanced fertilizer like Dyna-Gro Grow Formula 7-9-5, and add Dyna-Gro Mag-Pro 2-15-4 occasionally to promote flowering.
Water Quality
- Use rainwater or distilled water to avoid chemicals and toxins found in tap water.
Monitoring
- Observe the orchid closely for signs of stress or damage, and adjust the water level or fertilization accordingly.
Troubleshooting Tips
Root Rot
- If you notice root rot, reduce watering and ensure the roots have time to dry out between waterings.
Leaf Drop
- If leaves are dropping, check for overwatering and adjust the watering schedule accordingly.

Contaminants and Chemicals
Algae Growth
- To prevent algae growth, use a double pot method with a clear liner and holes inside a cover pot.
Tap Water Chemicals
- Avoid using tap water, which may contain chemicals and toxins harmful to orchids. Instead, use rainwater or distilled water.
Alternatives
- If you find water culture challenging, consider repotting the orchid in a traditional bark mix.
