1. Soil requirements
Alocasia macrorrhizos (giant taro) has basically no requirements for the growing soil, and ordinary garden soil can be used to cultivate it. If you want Alocasia macrorrhizos to be grown more beautifully and attractively, with higher ornamental value, then use soil mixed from materials such as perlite, vermiculite, peat soil, sandy loam, and leaf mold to promote root development.
