Planting
For potted Alocasia amazonica, use loose, well-drained, airy soil rich in humus. Generally, a mix of equal parts leaf mold, garden soil and river sand can be used as the substrate. Usually repot once every spring, and loosen the soil once a month to keep the potting soil in a well-aerated state.
Growing Methods for Alocasia amazonica
Watering
Follow the principle of "don't water until dry, and water thoroughly when you do," avoiding prolonged waterlogging, which can cause root rot, but do not let it get too dry either, otherwise the plant will not die but will grow slowly, with dull leaf color and a lack of vitality. In winter, if the nighttime temperature is not below 5°C and the daytime temperature is above 15°C, the plant can continue to grow and can be watered normally; if watering is controlled to make the plant go dormant, it can also tolerate low temperatures of 0°C.
Light
Alocasia amazonica likes a sunny, cool and dry environment. Its main growing period is in the cooler spring and autumn seasons, and during the growing period it requires plenty of sunlight. If there is insufficient light, the plant form will become loose and not compact, affecting its ornamental value, while plants grown in sufficient light have thick, plump leaves, a compact form and beautiful leaf color.

Fertilizing
Alocasia amazonica quite likes fertilizer. From March to October, apply a liquid fertilizer once every half month, and the proportion of nitrogen can be appropriately increased; adding a little ferrous sulfate is even better. This way the leaves will grow as large as lotus leaves and be smooth and lovely. When the temperature is below 15°C, fertilizing should be stopped.
Pruning
Alocasia amazonica placed indoors is generally required to be small and delicate. When you observe that the Alocasia amazonica has grown to a suitable size, immediately spray the whole plant with a 2% paclobutrazol solution, which can control the height of the stems and leaves, and the leaves will be thick and suitable for viewing. Usually spraying once about every half a year can maintain a suitable height.
