🌿 Alocasia nobilis Care Guide

Alocasia nobilis is a rare species native to Borneo, admired for its elegant, elongated leaves with pronounced veins and a slightly metallic or bluish-green sheen. Like most Alocasias, it thrives in warm, humid, and bright conditions with careful watering.

☀️ Light

• Prefers bright, indirect light.

• Avoid direct midday sunlight, which can burn or dull the foliage.

• Morning or late afternoon sun is fine if filtered through curtains.

• Too little light leads to slower growth and paler leaves.

💡 Tip: Near an east or bright north-facing window is ideal.

🌡️ Temperature

• Keep between 20–30 °C (68–86 °F).
  

• Stable warmth encourages lush growth and prevents dormancy.

💧 Watering

• Water when the top 2–3 cm (1 in) of soil feels dry.

• Water deeply until it drains out the bottom, then discard excess water.

• Do not let the plant sit in water — Alocasia roots are prone to rot.

• In cooler or darker months, reduce watering slightly.

💧 Consistency is key: the soil should stay evenly moist but never soggy.

🌫️ Humidity

• Thrives in high humidity (60–85%).

• If the air is dry, use a humidifier or place the plant on a pebble tray with water.

• Grouping plants together can help maintain humidity levels.

• Browning leaf edges often indicate air that’s too dry.

🌱 Soil

• Use a loose, airy, well-draining aroid mix.
  Recommended mix:

  • 40% coco coir or peat moss

  • 30% orchid bark

  • 20% perlite or pumice

  • 10% charcoal or sphagnum moss

• This balance allows airflow while retaining gentle moisture.

🌾 Fertilizer

• Feed every 3–4 weeks during spring and summer.

• Use a balanced liquid fertilizer diluted to half strength.

• Stop or reduce fertilizing in autumn and winter when growth slows.

💡 Over-fertilizing can cause leaf burn — less is more.

🪴 Repotting

• Repot every 1–2 years, ideally in spring or early summer.

• Choose a pot 2–3 cm larger than the current one with good drainage holes.

• Handle roots gently — they’re sensitive to disturbance.

🌘 Dormancy

• In cooler seasons or low light, growth may slow or stop.

• Some leaves may yellow and drop naturally — this is normal.

• Reduce watering, keep warm and humid, and wait for spring growth to resume.

🐾 Toxicity

All parts of Alocasia nobilis are toxic if ingested, containing calcium oxalate crystals.
Keep out of reach of pets and children.
