Care Requirements
Light
Prefers bright, indirect light. It will tolerate medium light but may lose some intensity in its coloration. Avoid direct sunlight, which can damage the delicate metallic surface.
Water
Keep the top 1–2 inches of soil slightly moist, allowing it to dry lightly between waterings. Avoid oversaturation, as Alocasia cuprea is prone to root rot if kept in soggy soil.
Humidity
Thrives in high humidity, ideally 60 percent or higher. Increased humidity preserves the glossy surface and supports steady growth.
Temperature
Best kept between 70–85°F. Protect from drafts, cold windows, and sudden temperature changes. Avoid temperatures below 60°F.
Soil
Use a breathable, well-draining aroid mix such as:
- Potting soil with added perlite
- Orchid bark and coco coir blends
- Any chunky, airy substrate for tropicals
Fertilizer
Fertilize once a month during spring and summer with a balanced liquid fertilizer at half strength. Reduce feeding in winter.
Growth Notes
‘Red Secret’ is naturally slow-growing and prefers stable warmth and humidity. It may drop a leaf or pause growth in cooler months. New leaves will always emerge lighter and more vibrant before maturing into deeper tones.
Pet Safety
Toxic to pets if ingested. Contains calcium oxalate crystals and should be kept away from animals and children.
