Caring for
Tolumnia
Tolumnia orchids, also known as equitant oncidiums, are a type of orchid that are native to the Caribbean and South America. These small orchids are known for their colorful, long-lasting flowers and compact size, making them a popular choice for indoor and outdoor growing. Here is a care sheet to help you grow and care for your Tolumnia orchids:
Light: Tolumnia orchids prefer bright, filtered light. They can tolerate direct sunlight for short periods of time, but prolonged exposure can damage their leaves and flowers. A good location for Tolumnia orchids is an east-facing windowsill or a shaded patio.
​
Temperature: Tolumnia orchids grow well in warm temperatures, between 60-85°F (15-29°C). They can tolerate higher temperatures, but they may require more frequent watering. Tolumnia orchids do not tolerate cold temperatures and should be kept away from drafts and cold air.
​
Humidity: Tolumnia orchids prefer high humidity, between 50-70%. You can increase humidity by misting the leaves and placing a tray of water near the orchid. Avoid spraying water directly onto the flowers or growing tip.
​
Watering: Tolumnia orchids require frequent watering, but their potting mix should be allowed to dry slightly between watering. Water the orchid thoroughly until water runs out of the drainage holes, and then allow the potting mix to dry out slightly before watering again. Tolumnia orchids do not tolerate standing water or overwatering, which can cause root rot.
​
Fertilizer: Tolumnia orchids should be fertilized regularly during the growing season, from spring to fall. Use a balanced, water-soluble orchid fertilizer diluted to half strength, and apply it every two weeks. During the winter, reduce fertilization to once a month.
​
Potting: Tolumnia orchids prefer a well-draining potting mix, such as a mix of bark, perlite, and sphagnum moss. They can be grown in a small pot or in a hanging basket. Repot the orchid every two years or when the potting mix breaks down.
​
Pests and Diseases: Tolumnia orchids can be susceptible to mealybugs, spider mites, and scale insects. Check the leaves and flowers regularly for signs of infestation, and treat them promptly with a suitable insecticide. Tolumnia orchids can also be affected by fungal and bacterial diseases, which can be prevented by providing good air circulation and avoiding overwatering.
Propagation: Tolumnia orchids can be propagated by dividing the plant at the roots. Gently remove the orchid from its pot and separate the clumps, making sure each division has a healthy root system. Repot the divisions in fresh potting mix and care for them as you would a mature plant.
With proper care, Tolumnia orchids can bloom profusely and bring color and beauty to any space.
