● How to Care for Alocasia cuprea 'Red Secret'

Follow this Alocasia cuprea 'Red Secret' indoor care guide to maintain its glossy metallic finish and compact structure year-round.
  
Light: Bright, indirect light keeps the metallic tone vibrant (light orientation guide); avoid direct sun that can dull the sheen.
  
Watering: Water when the top 10–15 % of soil is dry; never allow to sit in water (watering guide).
  
Humidity: Maintain 60–80 % RH to prevent edge crisping; stable humidity preserves leaf gloss (humidity control tips).
  
Temperature: Keep between 20–30 °C; protect from cold drafts and sudden drops.
  
Soil mix: Use a light, airy blend of orchid bark, perlite, and coco fiber for strong, healthy roots (substrate guide).
  
Fertilising: Apply diluted, balanced fertiliser every 3–4 weeks during active growth to support leaf formation.
  
Repotting: Refresh substrate every 1–2 years and choose a pot one size larger once roots fill the container.

● Styling and Placement

Position near an east- or north-facing window for soft, consistent light. Alocasia cuprea 'Red Secret' pairs beautifully with matte black or metallic planters to accentuate its sheen. Rotate the pot monthly for symmetrical growth, and wipe leaves gently with a damp cloth to maintain a mirror-like finish.

● Common Issues and Solutions

  
Drooping leaves: Usually caused by underwatering or temperature stress — keep soil evenly moist and conditions stable.
  
Brown edges: Low humidity; increase ambient moisture.
  
Yellowing: From overwatering or compacted mix; let soil dry slightly before the next watering.
  
Pests: Spider mites and thrips may appear in dry air; inspect undersides weekly and treat early (thrips  and pest guide).
