I grow it on regular soil, I add some rice husk to provide a more airy soil, add some garden compost. I add bit of slow release fertilizer (Osmocote), and recently I also add bit insecticide-nematicide to the potting soil (Carbofuran pellets), as I am lazy on taking care of plants, and I saw too many bugs on my plants, so I need to take bit control... I use to avoid pesticide, if possible, but I guess in pots it's OK, and this is only for ornamental plants.
Sorry the picture is just a small plant, as it was already splitted for sale, and I only keep one for me.
I thinks this one is not too much demanding compared to some other aroids.
