Why is my Calathea turning yellow?
There are several reasons why your calathea may be turning yellow. It could be due to too much or too little light, overwatering, or pests.

If the soil is too dense or wet, the roots will not be able to get the oxygen they need, and the leaves will begin to yellow.
How to Fix: Improving the quality of the soil is often the best solution for this problem. However, if the yellowing leaves are accompanied by wilting or brown spots, it could also be a sign of root rot. In this case, it is best to consult with a professional before taking any action.
