For the best performance and for the foliage to retain its deep green colouring, it is best to situate your Alocasia Amazonica in a location that receives bright indirect light. If you live in an area where the temperatures and light conditions are not intense can place it in a location that receives direct sunlight.
If placed in a location lacking enough light the plant loses its colour, including the leaf veins and can eventually die. Even when placed in a location that receives a medium amount of light, the plant won’t be happy and won’t produce the best growth and leaf coloration as when placed in a brighter location. So, experiment on locations and keep an eye of its health and change locations where necessary.
As with most tropical plants, maintain evenly moist but not soggy soil during the growing season, watering when the surface begins to dry. Reduce watering significantly in winter.
