Calatheas are beautiful indoor plants that have become increasingly popular in recent years. These plants have unique foliage patterns and come in a variety of colors, making them a great addition to any home. However, to keep these plants thriving, they need proper care, including fertilization. In this article, we will cover the basics of Calathea plant fertilizer, including tips and best practices to help your plants flourish.
What is Calathea plant fertilizer?
Calathea plant fertilizer is a type of plant food that provides essential nutrients to Calathea plants. These nutrients include nitrogen, phosphorus, and potassium, which are essential for plant growth and development.
The importance of fertilizing Calathea plants
Fertilizing Calathea plants is important to ensure they receive the nutrients they need to grow and thrive. Without proper fertilization, Calathea plants may become stunted, have weak growth, and produce smaller leaves. Additionally, fertilization helps to maintain the overall health of the plant and promote disease resistance.
When to fertilize Calathea plants
Calathea plants should be fertilized during the growing season, which typically occurs in the spring and summer months. It is not recommended to fertilize Calathea plants during the fall and winter months when growth slows down. Additionally, avoid fertilizing newly transplanted Calathea plants for the first six months.
Types of fertilizer for Calathea plants
There are two main types of fertilizer for Calathea plants: liquid and granular. Liquid fertilizers are water-soluble and can be applied directly to the soil or mixed with water and sprayed onto the leaves. Granular fertilizers are slow-release and are applied to the soil, where they release nutrients over time.
Organic vs. synthetic fertilizer for Calathea plants
Organic fertilizers are made from natural materials, such as compost or manure. Synthetic fertilizers, on the other hand, are made from chemical compounds. While both types of fertilizers can be effective, organic fertilizers are typically more sustainable and environmentally friendly.
How to apply Calathea plant fertilizer
To apply Calathea plant fertilizer, dilute liquid fertilizer with water according to the manufacturer’s instructions and apply it to the soil. For granular fertilizer, sprinkle it on the soil and water the plant afterward to help activate the fertilizer. Be sure to apply fertilizer evenly and avoid getting it on the leaves, as this can cause damage.
Common mistakes to avoid when fertilizing Calathea plants
Some common mistakes to avoid when fertilizing Calathea plants include over-fertilizing, under-fertilizing, and applying fertilizer to dry soil. It is important to follow the manufacturer’s instructions and avoid applying too much fertilizer, as this can cause plant damage.

Signs of over-fertilization in Calathea plants
Over-fertilizing Calathea plants can cause several issues, including leaf burn, stunted growth, and root damage. Some signs of over-fertilization include:
- Leaf discoloration or yellowing
- Burnt leaf edges
- Wilting or drooping leaves
- Stunted growth
- Root rot
If you notice any of these signs, it is essential to adjust your fertilization practices to prevent further damage to the plant.
How to fix over-fertilized Calathea plants
If you have over-fertilized your Calathea plant, it is crucial to act quickly to prevent further damage. The first step is to flush the soil with water to help remove excess fertilizer. You can do this by thoroughly watering the plant and allowing the water to drain through the soil. Repeat this process several times until you no longer see fertilizer runoff.
After flushing the soil, it is best to give the plant some time to recover. You may also want to consider repotting the plant if it is severely over-fertilized, as this can help refresh the soil and prevent further damage.
How to care for Calathea plants in the absence of fertilizers
While fertilization is essential for Calathea plants, they can still survive in the absence of fertilizers. To care for Calathea plants without fertilizers, make sure they are receiving adequate light and water, and avoid placing them in areas with extreme temperatures or drafts.
Additionally, you can improve the soil quality by adding organic matter, such as compost or peat moss, which can help provide some essential nutrients.
