A detailed guide to growing Alocasia (Alocasia macrorrhizos), also known as the giant taro

Alocasia can only grow well in an environment no lower than 18°C. If the temperature drops below 18°C, the Alocasia will enter a dormant state and stop growing.

Alocasia is not very cold-hardy, and the winter temperature must not drop below 5°C. Alocasia planted in courtyards should be moved indoors in mid-October.

Alocasia can be propagated by division, cuttings, sowing and other methods. The cutting method is suitable in spring, summer and autumn. During the cutting period, the substrate should be kept moist, and the air humidity should also be increased. The cut old stems can be cut into small sections about 15 cm long, left in a shaded place to dry for half a day, and then inserted into sandy loam soil for cultivation. In 7-10 days, many sturdy roots will grow. During the cultivation of the old plant, because the environment is shady and damp, or in summer and autumn, spray water on the leaf surface every morning and evening for maintenance. The division method is carried out in spring and autumn. At this time, the Alocasia tubers will sprout small leafy seedlings, which can be divided when repotting and changing the soil.
