Cymbidium orchids, also known as the Boat Orchid, are a popular and versatile genus of orchids that can grow as epiphytes, lithophytes, or terrestrials. These orchids are prized for their long-lasting, vibrant blooms that come in a variety of colors. Whether you’re a seasoned orchid grower or just starting out, understanding the ideal growing conditions for Cymbidium orchids and how to properly care for them is key to ensuring their health and longevity.
Ideal Growing Conditions for Cymbidium Orchids
Temperature
Cymbidium orchids thrive in a temperature range of 55-65°F (13-18°C). They prefer cooler temperatures, especially during the active growth and blooming periods.
Humidity
These orchids require high humidity levels, typically between 75-85%. Maintaining proper humidity is crucial to prevent issues like Botrytis and Anthracnose flower blight.
Water
Cymbidiums prefer medium-quality water, avoiding softened water. The potting medium should be kept consistently moist but not waterlogged.
Light
Cymbidium orchids need bright light, but with some shade during the day. Adequate light is especially important during active growth and to initiate blooming.
Watering Cymbidium Orchids
Proper watering is essential for the health and longevity of Cymbidium orchids. Here are some guidelines on how often to water your Cymbidium:
- During active growth and blooming: Water when the potting medium is slightly dry to the touch, typically every 5-7 days.
- During dormancy: Water less frequently, allowing the medium to dry out more between waterings, typically every 10-14 days.
- Avoid letting the roots sit in water, as this can lead to root rot.
- Use room-temperature water and avoid softened or distilled water, as they can be detrimental to the plant.
Epiphytic, Lithophytic, and Terrestrial Cymbidiums
Cymbidium orchids can be classified into three main growth habits:
| Growth Habit | Description |
|---|---|
| Epiphytic | Grow on trees or other plants, using them for support but not nutrients. |
| Lithophytic | Grow on rocks or other inorganic surfaces. |
| Terrestrial | Grow in the ground, in soil or other organic media. |
Each growth habit has slightly different environmental requirements, so it’s important to consider the specific needs of your Cymbidium orchid when providing care.
Troubleshooting Common Issues
Chilling Injury or Ethylene Damage
Symptoms include translucent or dried patches on petals and sepals, or darkening of the lip and column. This can be caused by exposure to cold temperatures or ethylene gas.
Botrytis and Anthracnose Flower Blight
These fungal diseases can cause flowers to develop brown or gray spots and eventually wilt. Maintaining good sanitation and humidity levels can help prevent and control these issues.
Conclusion
Cymbidium orchids, with their boat-shaped, long-lasting blooms, are a beautiful and rewarding addition to any orchid collection. By understanding their ideal growing conditions, proper watering techniques, and common troubleshooting tips, you can ensure your Cymbidium orchids thrive and continue to delight you with their vibrant, fragrant flowers.
