To care for an Alocasia scalprum, provide bright, indirect light and maintain high humidity, ideally above 60%. Keep the soil evenly moist but not waterlogged, allowing the top few inches to dry between waterings. Use a well-draining soil mix and a pot with drainage holes to prevent root rot. Maintain a warm temperature range of 18–27°C (65–80°F) and protect it from cold drafts. Fertilize monthly during the growing season and watch for common pests like spider mites.
