How to Care for Alocasia cuprea 'Red Secret'



Placement: Keep in a warm, humid environment, away from cold drafts and temperature fluctuations.
Light: Prefers bright, indirect light to maintain its metallic sheen. Avoid direct sunlight, which may scorch the leaves. Can tolerate artificial grow lights if natural light is insufficient.
Watering: Keep soil evenly moist but never soggy. Allow the top 2-3 cm of soil to dry before watering again. Overwatering can lead to root rot, while underwatering may cause drooping leaves.
Humidity: Requires high humidity (above 60%). Use a humidifier or group plants together to increase moisture levels. A humidity tray can also help maintain moisture.
Temperature: Maintain between 20°C and 30°C. Avoid sudden drops in temperature or drafts.
Soil: Use a well-draining, airy mix containing orchid bark, perlite, and coconut soil.
Repotting and Pot Choice: Repot when rootbound, ideally in a breathable terracotta pot to promote air circulation.
Fertilizing: Feed with a balanced liquid fertilizer every 2-4 weeks during the growing season. Avoid over-fertilization to prevent salt buildup.
Propagation: Best propagated by division of rhizomes when repotting.
Semi- and Hydroponics: Thrives in semi-hydroponic setups like LECA. Ensure adequate nutrient balance and oxygenation in hydroponic systems.
Pruning: Trim old or damaged leaves at the base of the petiole using sterilized scissors.
