Special orchid care tips for Oncidium (bump flower)

Oncidiums need a bright windowsill. From March to September, however, the plant must be protected from direct sunlight. The optimum temperatures are between 18 and 25 °C. It may be cooler at night and during the winter months. Please only water as soon as the orchid substrate is completely dry. Oncidium roots are quite sensitive and should therefore only be fertilised lightly. Do not fertilise at all during the winter months.

Care instructions for Oncidium orchids:

1. light: Oncidium orchids prefer bright, indirect light. They can tolerate some direct morning sun or late afternoon sun, but should be protected from intense midday sun. A location near an east or west-facing window is ideal.
2. temperature: Oncidium orchids thrive well in moderate temperatures. During the day, temperatures should be between 18-25°C, while night temperatures may drop to 13-18°C. Some species prefer a slight chill at night, which can promote flower formation.
3. watering: Oncidium orchids like to be kept evenly moist, but should not be standing in water. Allow the substrate to dry slightly before watering again. Waterlogging should be avoided as this can lead to root rot.
4. humidity: These orchids prefer a moderate humidity of around 40-60%. In drier environments, a humidifier or regular spraying of the plant can be helpful to increase the humidity.
5. substrate: Use a well-drained orchid substrate, which can consist of coarse bark, sphagnum moss and perlite. This substrate allows good air circulation around the roots and prevents waterlogging.
6 Fertilisation: Fertilise the orchid every fortnight during the growing season (spring and summer) with a balanced orchid fertiliser. In autumn and winter, fertilisation can be reduced to once a month.
7 Repotting: Oncidium orchids should be repotted every two to three years or when the substrate starts to decompose. The best time to repot is after flowering or in early spring.

By following these care tips and knowing the special characteristics of Oncidium orchids, you can optimally care for and enjoy these fascinating plants.
