Components which are Best Soil for Calathea
Three main components that should be present in the soil to make it the best soil for Calathea are:

Adding coco coir will improve drainage in the mix of the calathea.
Good aeration- Calathea likes light soil that should have good aeration. As they love dry and porous soil to get the proper aeration, giving that will help them grow. Providing extra aeration to the soil will boost the growth of the plant.
Texture- The texture of the soil for Calathea should be from coarse light. The Calathea soil prefers very light and loose soil which also holds enough moisture which helps in root growth. The texture of indoor and outdoor soil can vary as one will be in a pot and the other in the land.
