Frequently watering your Calathea with or one that has a poor drainage facility is dangerous.
Overwatering decreases or even cuts off the supply of oxygen to the roots. Roots depend on oxygen to function correctly. Insufficient oxygen level is a threat to its survival.
Moreover, overwatering can lead to root rot. Excess water in the soil will cause waterlogging, which will restrict the airflow between the roots. This condition will suffocate your plant.
The signs of overwatering are:

- New leaves turn yellow or brown before maturing.
- Leaves falling

- Use fertilizers with an NPK (Nitrogen: phosphorus: potassium) ratio of 10:10:10.
- Before using fertilizers, make sure that you are pretty knowledgeable about the method of fertilization and the type of fertilizer to use.
