What kind of soil does alocasia reginae like?
This plant is happiest in well-draining soil. You can give it the best soil for its needs by mixing ingredients like orchid bark, pumice, leca, or coconut fiber.
In my experience, good planting media are like peat moss, coco coir, and perlite because they provide nutrients and improve soil structure.
Just make sure you use a potting mix that allows good drainage, so your plants don't have to struggle.
