Do a pH test to find the soil pH level.
What Kind of Soil is used for Calathea?
The best soil for Calathea is no soil. Calatheais adapted to fewer nutrients and full drainage soil making the need for soil less. They prefer a growing medium that is looser with lots of air pockets, unlike regular soil. Regular soils may trap water and make soil damp which may lead to root rot and plant death.

Instead, look for a potting mix specially made for cactus or orchids which gives the right place for the plant. Calathea can get water from the air in a way also from bark or moss.
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:
Well-Drainage- A well-draining soil is essential for calathea. If grown in a pot, it needs a drainage hole for proper drainage. Water sitting in the pot may lead to fungal disease and destroy the root. Adding pebbles to the pot with soil will help solve the problem. 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.
What kind of potting mix is good for Calathea?

How to Prepare a Potting Mix for Calathea?
To prepare the potting soil for Calathea, add one part of the Perlite, and one part of Coco coir to one part of the Pine Barks.

The preparation of a potting mix for Calathea is easy and cost-efficient. Succulent, cactus soil is quite opposite to garden or potting soil. Succulent soil loves to have very good porous drainage but having that for this plant might be a wrong idea. Adding potting mix directly for calathea makes the root of the plant rot.
