The best fertilizer for Calatheas
Want your Calathea to grow healthy, lush, and full of beautifully colorful leaves? The right fertilizer can help, but you don't need anything complicated.
The best fertilizer for Calathea is a balanced, diluted liquid houseplant fertilizer. A gentle formula like this one is ideal because Calatheas can be sensitive to excess fertilizer.
How often should you fertilize a Calathea?
Fertilize your Calathea about once a month during spring and summer, when it's actively growing.
In fall and winter, when growth slows down, stop or reduce fertilizing.
Always follow the instructions on the fertilizer bottle. And remember: more fertilizer isn't better! Too much can cause brown leaf edges and damage the roots.

Does Calathea need special fertilizer?
No. You don't need a fertilizer specifically made for Calatheas.
A balanced liquid fertilizer for houseplants works well. If you're concerned about overfertilizing, use it at a weaker concentration than the maximum recommended on the label.
Note that fertilizer isn't the most important part of Calathea care. Bright, indirect light, consistent moisture, and good humidity are much more important.
