Oncidium Yuan Nan Gold is a beautiful and fragrant hybrid orchid, known for its yellow and brown flowers and long spikes. It’s a cross between Oncidium Sharry Baby and Oncidium sphacelatum.

Here’s a comprehensive guide for Oncidium Yuan Nan Gold care:

1. Light:

• Ideal: Bright, indirect light is best. An east or west-facing window is usually suitable.
• Signs of proper light: Leaves should be a light yellow-green. Dark green leaves might indicate insufficient light, while reddish-tinted leaves could mean too much light.
• Avoid: Direct, harsh sunlight, especially during the hottest parts of the day, as it can scorch the leaves.

2. Temperature:

• Daytime: 21−29∘C (70−85∘F)
• Nighttime: 13−16∘C (55−60∘F)
• Oncidium Yuan Nan Gold prefers intermediate to warm growing conditions.

3. Humidity:

• Oncidiums, including Yuan Nan Gold, prefer a humidity level of 40-80%, with some sources suggesting 60-80% for this particular hybrid.
• To increase humidity:
  • Use a humidity tray (a saucer with pebbles and water, ensuring the pot doesn’t sit in the water).
  • Use a room humidifier.
  • Mist the leaves occasionally, especially in dry environments.

4. Watering:

• Frequency: Water thoroughly every 7-10 days during active growth (spring to fall). Reduce watering to every 10-14 days in winter.
• Method: Allow water to drain completely from the pot to prevent soggy roots, which can lead to root rot. Never let the pot sit in standing water.
• How to check: The potting medium should be half dry before rewatering. You can also insert a wooden popsicle stick or chopstick into the pot; if it comes out dry, it’s time to water. Oncidiums are thirsty orchids, and a common issue is under-watering, which can make them look “sad.”

5. Potting and Medium:

• Medium: Use a well-draining orchid mix. Common mixes include bark, perlite, and sphagnum moss. Coconut husk chips are also a good option as they retain moisture while allowing good aeration.
• Repotting: Repot every 2-3 years, or when the potting medium starts to break down. The best time to repot is in spring when new growth appears.
• Pot size: Small, deep pots are often preferred to accommodate their root systems.

6. Fertilizing:

• Frequency: Fertilize every two weeks during active growth.
• Type: Use a balanced orchid fertilizer (e.g., 20-20-20 or 19-19-19 NPK) diluted to half or quarter strength.
• During blooming: Some sources suggest a bloom-booster formulation (e.g., 10-30-20) as flower spikes are forming.
• Important: Never fertilize a completely dry plant, as this can damage the roots. Flush the potting mix with plain water once a month to prevent salt buildup.

7. Air Circulation:

• Good air circulation is crucial to prevent fungal issues, especially with higher humidity. A small fan can be beneficial in enclosed spaces.

8. Blooming and Dormancy:

• Oncidium Yuan Nan Gold can bloom multiple times a year, typically in spring and fall.
• After blooming, cut the flower spike off at the base. Allow the plant to rest with slightly reduced watering and feeding.

Tips for Success:

• Root health: Healthy roots are firm and white or green.
• Fragrance: Oncidium Yuan Nan Gold is known for its pleasant fragrance, inherited from Oncidium Sharry Baby.
• Observation: Pay attention to your plant’s leaves and pseudobulbs. Wrinkled pseudobulbs often indicate a need for more water.

By following these guidelines, you can enjoy the beautiful and fragrant blooms of your Oncidium Yuan Nan Gold orchid!
