Calatheas are fascinating plants that come in a wide range of colours and patterns. They are also rather expressive, closing their leaves up at night and unfolding them again in the daytime.
As Calatheas like to be kept on the damp side a soil that holds some moisture without becoming soggy is ideal.
Calatheas can tolerate lower light than a lot of houseplants making them an attractive option. Somewhere with low to bright light will work but avoid direct sun as it can bleach the leaves.
Calathea prefers moist soil, when the top one to two inches of soil has dried out it is time to water. Calatheas also prefer higher humidity, you can try pebble trays filled with water to increase humidity.
Calatheas don't require any pruning but do remove yellowing or dead leaves.
