🌸 Vanda Orchid Care — Alan’s Garden Guide

Vanda orchids are stunning, sun-loving orchids known for their vibrant colors and long-lasting blooms. They need bright light, high humidity, and excellent airflow.

☀️ Light Requirements

• Give very bright, filtered sunlight.
• Morning sun + bright indirect light for the rest of the day is ideal.
• Avoid harsh midday sun in Kerala/Tamil Nadu climates, as it can scorch leaves.

Signs:

• Yellowish leaves = too much sun
• Dark green leaves = too little sun

---

🌡️ Temperature

• Day: 24–32°C
• Night: 18–22°C
• They love warm, humid weather — perfect for Alan’s Garden climate.

💧 Watering

Vandas have bare roots, so watering is crucial.

If hanging bare-root:

• Water daily in summer.
• Water every 2–3 days in rainy/cool weather.
• Soak roots until they turn green, then allow to dry fully.

If potted in baskets:

• Water 3–4 times a week depending on heat and airflow.

Tip: Never let roots stay soggy — they need wet → dry cycles.

💦 Humidity

• Needs 60–80% humidity.
• Mist roots daily if humidity is low.
• Ensure good airflow to prevent fungal issues.

🌱 Fertilizer

Feed Vanda orchids regularly; they are heavy feeders.

• Use balanced NPK 20-20-20 once a week.
• Use Bloom booster (e.g., 10-30-20) twice a month during flowering season.
• Flush roots with plain water once a month to remove salt buildup.

🪴 Potting / Mounting

• Best grown hanging bare-root in a basket or wooden slat.
• If using media, choose:
  ✔️ Large charcoal
  ✔️ Large bark
  ✔️ Coconut husk chunks (well washed)

Repot every 2–3 years only if roots overflow excessively.
