● How to Care for Alocasia infernalis 'Black Magic'

This Alocasia infernalis 'Black Magic' care guide ensures you maintain its rich color and compact growth all year round.
  
Light: Provide bright, indirect light to preserve its metallic sheen; avoid strong midday sun.
  
Watering: Keep soil evenly moist but never soggy; water when the top 20 % feels dry (watering guide).
  
Humidity: Aim for ≥70 % RH; steady moisture preserves the glossy texture and prevents crisping (humidity guide).
  
Soil mix: Use a well-draining substrate rich in organic matter and aeration components such as bark and perlite blend.
  
Fertilising: Apply diluted, balanced liquid fertiliser every 4–6 weeks during active growth; reduce in cooler months.
  
Temperature: Keep between 20–28 °C; avoid sudden temperature drops and cold drafts.
  
Repotting: Refresh substrate every 1–2 years or once roots fill the pot; always provide drainage.
  
Propagation: Divide rhizomes or offsets during repotting; ensure each has roots and a viable node.
