In the 20th century, orchid cultivation expanded to the United States and Asia, with Taiwan becoming a major producer. Oncidium remains one of the most popular orchids among enthusiasts due to its stunning appearance and relative ease of care.

Gardening Tips

With proper care, Oncidium can thrive and produce beautiful flowers for a long time.

Sunlight

Prefers bright, indirect light. Direct sunlight can cause leaf burn, so filtered light is ideal.

Watering

Water thoroughly when the growing medium dries out. The pseudobulbs store moisture, so avoid overwatering. Reduce watering in winter to encourage blooming.

Soil

Well-draining orchid mix, such as bark chips or sphagnum moss, helps maintain healthy roots.

Fertilizer

Apply a diluted liquid fertilizer once or twice a month during the growing season for optimal flowering. Avoid over-fertilization, as it can damage roots.

Temperature

Thrives in temperatures between 15–25°C (59–77°F). Protect from temperatures below 10°C (50°F), especially in winter.

Humidity

Prefers high humidity but requires good air circulation to prevent diseases. Light misting or using a humidifier can help maintain proper moisture levels.

Repotting

Repot every 2–3 years when the roots outgrow the pot, preferably in spring or early summer.
