🌸 Oncidium Orchid (Dancing Lady) Care Guide – For Alans Garden

Oncidiums are known for their bright, dancing lady–shaped flowers and long arching sprays. They grow fast and bloom multiple times a year when given the right care.

---

🌤 Light

• Requires bright indirect light.
• 1–2 hours of soft morning sun is ideal.
• Leaf color guide:
  • Bright green → perfect
  • Dark green → not enough light
  • Yellowish → too much sun

Avoid harsh afternoon sunlight.

---

💧 Watering

• Water when the top 30–40% of the medium is dry.
• Keep evenly moist, never soggy.
• Oncidiums have thin pseudobulbs and dry out faster than phalaenopsis.
• Reduce watering during very cold months.

Signs:

• Wrinkled pseudobulbs = underwatering
• Yellow leaves = overwatering

---

☁️ Humidity

• Prefers 50–70% humidity.
• Mist lightly in the morning.
• Provide airflow to prevent fungal issues.

---

🌡 Temperature

• Ideal: 18–30°C
• Night drop of 4–6°C encourages blooming.
• Protect from temperatures below 15°C.

---

🌱 Potting Medium

Best medium for Oncidiums:

• Fine orchid bark
• • a little sphagnum moss
• • perlite for drainage

They prefer slightly finer mix than cattleyas.

---

🪴 Potting

• Repot every 1–2 years, preferably after flowering.
• Do not bury the pseudobulbs—keep them at surface level.
• Use a pot with plenty of drainage holes.

---

🍃 Feeding

• Use orchid fertilizer (balanced NPK) every 15–20 days, weak strength.
• Flush pot with plain water once a month to remove salt buildup.
• Stop feeding when plant enters rest period after flowering.

---

🌼 Blooming Tips

• Bright light = more blooms.
• A slight drop in night temperature triggers spikes.
• Avoid moving the plant once it starts forming spikes.
• Provide consistent moisture.
