Orchids, particularly the Oncidium species, are known for producing dozens of small flowers simultaneously, treating us to a marvelous display that lasts for several weeks. These flowers can come in various colors such as yellow, white, red, pink, green, or brown.
The unique characteristic shared by all Oncidium orchids is the lower petal being perpendicular to the lateral petals, giving them the common name of “dancing lady orchids.”
Orchid Varieties: There are hundreds of orchid species, all native to tropical and subtropical regions, including the Andes mountains, the humid forests of Jamaica, and the tropical river valleys of Brazil, Ecuador, and Peru.
Humidity Management: Maintaining proper humidity is crucial for Oncidium orchids. If the relative humidity drops below 50%, use a tray or pebble humidifier to increase moisture in the air. Grouping the plants together also helps to maintain a good humidity level. Lightly misting the leaves daily is another way to add moisture.
Cultivating Orchids: Oncidium orchids require ample light but should be protected from direct sunlight. If placing them near a window is not an option, consider using artificial lighting, such as fluorescent bulbs. Use a warm white and a cool white tube under a reflector. Position the orchids 20 centimeters below the light for 14-16 hours a day. Ensure they remain in darkness during the night, as plants also need rest.
Watering Orchids: Keep the orchid soil slightly moist during the growing season. Be cautious not to overwater, as Oncidium orchids store water in their pseudobulbs, making them more tolerant of dry soil than overly wet conditions. Water less during other times of the year, allowing the soil to dry thoroughly between waterings.
Transplanting Orchids: If you plan to transplant your orchid, the best time to do so is right after it has finished flowering. This timing allows the plant to produce new and stunning flowers with the benefit of nutrient-rich soil.
Following these tips will help you enjoy the continuous beauty of your Oncidium orchids, making them a delightful addition to your indoor garden.
