Calathea plants are known for their vibrant foliage and their ability to purify the air. However, in order to keep these plants thriving, it’s important to use the right fertilizer. The best calathea fertilizer will provide the necessary nutrients for growth and vibrant color while also avoiding any harmful chemicals that could harm the plant or the environment.
When choosing a calathea fertilizer, it’s important to consider the plant’s specific needs. Calathea plants prefer a slightly acidic soil with good drainage. Therefore, a fertilizer with a balanced NPK ratio, such as 10-10-10, is ideal. Additionally, organic fertilizers are a great option as they provide a slow release of nutrients and help to improve soil health.
Another important factor to consider is the frequency of fertilization. Calathea plants should be fertilized every 2-3 months during the growing season, which is typically from spring to fall. Over-fertilizing can lead to burnt leaves and other issues, so it’s important to follow the manufacturer’s instructions and avoid applying too much fertilizer.
After researching and testing various calathea fertilizers, I have identified the top options that will help your plants thrive.

How to Choose the Best Fertilizer for Calathea
As a plant enthusiast, I know how important it is to choose the right fertilizer for your Calathea. In this section, I will guide you through the factors to consider when choosing the best fertilizer for your Calathea.
Understanding the N-P-K Ratio for Calathea Fertilizers
The N-P-K ratio is a crucial factor to consider when choosing the best fertilizer for your Calathea. N-P-K stands for Nitrogen, Phosphorus, and Potassium, which are the three essential macronutrients that plants need to grow.
For Calathea, a balanced N-P-K ratio of 3-1-2 is ideal. This means that the fertilizer should contain three parts nitrogen, one part phosphorus, and two parts potassium. A balanced N-P-K ratio will promote healthy foliage growth and vibrant colors.
Soil pH Requirements for Calathea Fertilizers
Calathea plants prefer slightly acidic soil with a pH range of 6.0 to 6.5. Therefore, it is crucial to choose a fertilizer that matches the pH requirements of your Calathea.
Before choosing a fertilizer, test your soil pH using a soil pH tester. If the pH is too high or too low, adjust it accordingly using soil amendments before applying the fertilizer.
Liquid vs Granular Fertilizers for Calathea
When it comes to fertilizers, you have two options: liquid or granular. Liquid fertilizers are fast-acting and are quickly absorbed by the plant’s roots. On the other hand, granular fertilizers are slow-release and provide a steady supply of nutrients over time.
For Calathea, I recommend using a liquid fertilizer during the growing season and a slow-release granular fertilizer during the dormant season.
Synthetic vs Organic Fertilizers for Calathea
Finally, you need to choose between synthetic and organic fertilizers. Synthetic fertilizers are chemical-based and provide a quick boost of nutrients to your plants. Organic fertilizers, on the other hand, are made from natural ingredients and provide a slow-release of nutrients.
For Calathea, I recommend using organic fertilizers as they are gentle on the plant and provide a long-lasting supply of nutrients. However, if your plant is showing signs of nutrient deficiency, a synthetic fertilizer may be necessary.
In conclusion, choosing the right fertilizer for your Calathea is crucial for its growth and overall health. Consider the N-P-K ratio, soil pH, liquid vs granular, and synthetic vs organic options when selecting the best fertilizer for your Calathea.

Applying the right fertilizer in the right way can help your Calathea plant thrive. In this section, I will share some tips on how to apply fertilizer to your Calathea plant.
Applying Liquid Fertilizer to Calathea
Liquid fertilizer is a popular choice among plant owners because it is easy to apply and quickly absorbed by plants. When applying liquid fertilizer to your Calathea plant, follow these steps:
- Dilute the fertilizer according to the manufacturer’s instructions.
- Water your Calathea plant thoroughly before applying the fertilizer.
- Pour the diluted fertilizer into the soil around the plant, making sure not to get any on the leaves.
- Water the plant again to help the fertilizer soak into the soil.
Applying Granular Fertilizer to Calathea
Granular fertilizer is another option for feeding your Calathea plant. It is slow-release, meaning it will provide nutrients to your plant over an extended period. Here’s how to apply granular fertilizer to your Calathea plant:
- Sprinkle the granular fertilizer on the soil around your Calathea plant, following the manufacturer’s instructions for the correct amount.
- Gently work the fertilizer into the soil with a garden fork or trowel.
- Water the plant thoroughly to help the fertilizer soak into the soil.

Tips for Avoiding Fertilizer Burn on Calathea Plants
As a plant enthusiast, I know how important it is to keep your calathea plants healthy and thriving. Fertilizing your plants is a great way to give them the nutrients they need, but it’s important to do it correctly. Here are some tips to avoid fertilizer burn on your calathea plants:
- Dilute the Fertilizer: When fertilizing your calathea plants, it’s important to dilute the fertilizer according to the instructions on the package. Using too much fertilizer can cause fertilizer burn, which can damage your plants.
- Water Before Fertilizing: Before applying fertilizer, make sure to water your calathea plants thoroughly. This will help prevent the fertilizer from burning the roots of your plants.
- Use a Balanced Fertilizer: Calathea plants require a balanced fertilizer that contains equal amounts of nitrogen, phosphorus, and potassium. Using a fertilizer that is high in nitrogen can cause fertilizer burn.
- Apply Fertilizer Sparingly: It’s important to apply fertilizer sparingly to your calathea plants. Over-fertilizing can cause fertilizer burn, which can be harmful to your plants.
- Don’t Fertilize in Hot Weather: Avoid fertilizing your calathea plants during hot weather, as this can increase the risk of fertilizer burn.
By following these tips, you can avoid fertilizer burn on your calathea plants and keep them healthy and thriving.
When and How Often to Fertilize Calathea Plants
As a professional, I recommend fertilizing Calathea plants during the growing season, which is from spring to summer. During this time, the plant is actively growing and requires more nutrients to support its growth.
It’s essential to use a balanced fertilizer that contains equal amounts of nitrogen, phosphorus, and potassium. You can use a liquid, granular or slow-release fertilizer, depending on your preference.
When applying fertilizer, make sure to dilute it to half strength to avoid burning the plant’s roots. You can apply the fertilizer every two weeks during the growing season.
It’s important to note that Calathea plants do not require fertilization during the dormant season, which is from fall to winter. During this time, the plant is not actively growing, and fertilizing it can cause more harm than good.
In summary, fertilize your Calathea plants during the growing season, using a balanced fertilizer that contains equal amounts of nitrogen, phosphorus, and potassium. Dilute the fertilizer to half strength and apply it every two weeks. Avoid fertilizing during the dormant season to prevent damage to the plant.
The Verdict: Fertilizing Calathea Plants
After researching and testing various fertilizers, I have come to the conclusion that the best fertilizer for calathea plants is one that is balanced and specifically formulated for indoor plants.
When choosing a fertilizer, it’s important to consider the specific needs of your calathea plant. Calathea plants require a fertilizer that is high in nitrogen, as well as other essential nutrients such as phosphorus and potassium.
I recommend using a liquid fertilizer that is diluted in water and applied every two weeks during the growing season. This will ensure that your calathea plant receives the necessary nutrients for healthy growth.
It’s important to note that over-fertilizing can be harmful to your calathea plant. Be sure to follow the instructions on the fertilizer package and never exceed the recommended dosage.
In conclusion, the best fertilizer for calathea plants is a balanced, indoor plant-specific liquid fertilizer that is applied every two weeks during the growing season. Remember to always follow the instructions on the package and avoid over-fertilizing.
