- Calatheas prefer slightly acidic soil that drains well but remains damp between waterings.
- Adding coarse ingredients like perlite or tree bark can boost drainage, while mixing in spongy organic material like coconut coir is a good idea.
- Drainage holes in the container are critical, and any pot with drainage holes will work for Calatheas, but unglazed terra cotta is a good choice for overwaterers.
- Repot every 1-2 years, increasing container size by an inch or two each time, and signs that a Calathea needs repotting include slowed growth, brown leaf tips, and root poking through drainage holes.
Choosing Soil Type
When choosing soil for your Calathea, it’s essential to consider the soil composition. These plants prefer a slightly acidic mix that drains well but retains moisture between waterings.
A standard houseplant potting mix may be too water-retentive for Calatheas, so adding coarse ingredients like perlite or tree bark can boost drainage. Mixing in spongy organic material like coconut coir is also a good idea.
Moisture retention is crucial when it comes to Calathea soil. A blend that drains too quickly can dry out the plant, while a slow-draining mix can lead to waterlogged soil and root system invasion.
Pre-mixed potting soil for African Violets is a good option, or you can create your mix. Coarse elements and spongy organic material should be combined in roughly equal proportions to achieve the perfect balance of drainage and moisture retention.
To properly care for your container, make sure it has drainage holes and select a material that suits your watering habits. Calatheas prefer slightly moist soil, so it’s essential to avoid overwatering by choosing a container with adequate drainage.
Any pot with drainage holes will work for Calatheas, but unglazed terra cotta is a good choice for those who tend to overwater their plants. Terra cotta naturally wicks moisture away from the soil, preventing water from accumulating in the bottom of the pot.
If you’re looking to add some flair to your container decoration, there are alternative options to consider. You can repurpose items like teapots or mugs as long as they have drainage holes. Just be sure to choose a container that is the appropriate size for your plant and has adequate drainage.
Keep in mind that porous materials like unglazed terra cotta and ceramics will require more frequent watering than plastic or glazed containers. Ultimately, the perfect container for your Calathea will depend on your personal style and watering habits.
You can ensure that your Calathea thrives by using soil that’s slightly acidic and drains well but remains moist between waterings. The benefits of using acidic soil include better nutrient uptake, improved root growth, and increased resistance to disease.
To ensure that your soil is slightly acidic, you can test the pH levels using a soil testing kit. If the pH levels are too high, you can lower them by adding organic materials like peat moss, pine needles, or coffee grounds.
It’s important to note that Calatheas prefer soil that’s slightly acidic, not too acidic. A pH level between 5.5 and 6.5 is ideal for these plants. If the pH levels are too low, you can raise them by adding lime, wood ash, or eggshells.
To ensure that your Calathea thrives, it’s crucial to maintain the correct pH levels. By using slightly acidic soil, you can give your plant the best possible chance of growing healthy and strong.
One way to ensure your Calathea’s soil drains well is by adding coarse ingredients like perlite or tree bark. These elements improve aeration and reduce soil compaction, allowing water to flow through the soil more easily. Mixing in spongy organic material like coconut coir is another good idea, as it helps retain moisture while still allowing for drainage.
It’s important to remember that drainage holes in the container are critical for Calatheas. Without them, excess water can build up and lead to root rot. When repotting, consider using a pot with drainage holes and adding a layer of rocks or gravel at the bottom to further improve drainage.
By taking these steps, you can help ensure your Calathea’s soil remains damp but not waterlogged, promoting healthy growth and preventing potential issues.
Adding Organic Material
Incorporating spongy organic material like coconut coir into your potting mix can improve drainage and moisture retention for your Calathea. This material is made from the fibrous husks of coconuts and is a sustainable alternative to peat moss. Coconut coir is highly absorbent and can hold up to 10 times its weight in water, making it an excellent choice for improving moisture retention in your potting mix.
To use coconut coir, simply mix it into your potting mix at a ratio of one part coir to one part potting mix. As an added benefit, coconut coir is also a natural source of potassium and phosphorus, two essential nutrients for plant growth. Using organic materials like coconut coir in your potting mix can benefit your Calathea by promoting healthy root growth and improving overall plant health.
|Benefit||Reason||How to Use|
|Improves Drainage||Reduces risk of waterlogged soil, which can lead to root rot||Mix one part coconut coir to one part potting mix|
|Increases Moisture Retention||Holds up to 10 times its weight in water, providing consistent moisture to Calathea||Incorporate into potting mix for increased moisture retention|
|Natural Source of Nutrients||Contains potassium and phosphorus, essential nutrients for plant growth||Use coconut coir as an organic alternative to chemical fertilizers|

Importance of Drainage Holes
Ensure proper drainage for your Calathea by selecting a container with drainage holes to prevent waterlogged soil and root rot. Without adequate drainage, excess water will accumulate in the bottom of the pot, leading to suffocation of the roots and creating an environment for harmful pathogens to thrive.
Here are some tips to ensure proper drainage for your Calathea:
- Choose a container with multiple drainage holes to ensure water flows out quickly.
- Cover drainage holes with a layer of coarse material, like gravel or broken pottery, to prevent soil from clogging the holes.
- Elevate the pot with a saucer or pot feet to allow for even better drainage.
Proper watering is essential to prevent root rot, which can occur when the roots are constantly in damp soil. To avoid this, ensure that the soil is moist but not waterlogged, and allow the top inch of soil to dry out before watering again.
By selecting a container with drainage holes and following proper watering techniques, you can ensure your Calathea thrives and avoids the damaging effects of root rot.
You should aim to repot your Calathea every 1-2 years to prevent slowed growth, brown leaf tips, and root poking through the drainage holes. This frequency allows the plant to have enough space for its roots to grow and access fresh soil, which will provide the necessary nutrients for healthy growth.
When repotting, it’s recommended to size up by 1-2 inches in diameter from the previous pot, and to use fresh potting mix that’s well-draining yet retains moisture.
To determine if your Calathea needs repotting, look for signs such as a decrease in growth rate, brown leaf tips, or roots poking through the drainage holes. These indicate that the plant has outgrown its current container and requires more space for its roots to spread out.
Repotting can be done during the spring or summer months when the plant is actively growing, and it’s best to avoid disturbing the roots as much as possible. By following these guidelines, you can ensure that your Calathea has a healthy root system and can thrive in its new pot and soil.
To keep your Calathea hydrated, it’s important to monitor the soil moisture levels and adjust your watering schedule accordingly. Here are some tips to prevent overwatering and ensure your Calathea stays healthy and hydrated:
- Water your Calathea when the top inch of soil feels dry to the touch.
- Use room temperature water to avoid shocking the roots.
- Water from the bottom by placing the pot in a dish of water and allowing the soil to absorb the moisture. This will prevent water from collecting on the leaves and causing damage.
- Make sure your pot has adequate drainage to prevent water from sitting in the soil and potentially causing root rot.
- Consider using a moisture meter to accurately measure the moisture level in the soil and avoid overwatering.
By implementing these hydration techniques and preventing overwatering, you can ensure your Calathea stays hydrated and healthy.
Remember to monitor your plant’s soil moisture levels regularly and adjust your watering schedule accordingly to promote optimal growth and prevent damage.
African Violet Soil Mix
When using African violet soil mix for your Calathea, it’s important to mix coarse ingredients and spongy organic material in equal proportions. This will help ensure that the soil drains well while also retaining enough moisture to keep your plant healthy.
Some mixing options to consider include adding perlite or tree bark for drainage, and coconut coir for moisture retention. You may also want to consider using a semi-hydroponic approach using LECA, which can help regulate moisture levels and reduce the risk of disease.
Whatever mixing option you choose, be sure to monitor your plant’s hydration levels closely to make sure it’s getting the right amount of water.
Using a semi-hydroponic approach with LECA can provide a cleaner and more humidity-controlled environment for growing your Calathea. This method involves using a layer of LECA, or Lightweight Expanded Clay Aggregate, at the bottom of your container instead of traditional potting soil.
The LECA acts as a reservoir for water, allowing the plant to draw up moisture as needed. This approach can be particularly helpful for Calatheas, which prefer consistently moist soil.
However, it’s important to note that using a semi-hydroponic approach does require actively regulating pH and nutrient levels in the water. This can be done by using a specialized nutrient solution and monitoring the pH with a meter or test strips.
While this method may require a bit more attention to detail, it can be a great option for those looking for a low-maintenance and effective way to grow their Calatheas.
Advantages of Semi-Hydro
You can enjoy the benefits of a semi-hydroponic approach with your Calathea, such as increased humidity, easier watering, and reduced risk of disease. This method involves growing your plant in a pot filled with LECA (lightweight expanded clay aggregate) instead of soil.
The porous structure of LECA allows for excellent drainage and aeration, preventing water from getting trapped and causing root rot. Additionally, the constant supply of moisture from the water reservoir at the bottom of the pot creates a humid environment that Calatheas thrive in.
Reducing disease is another advantage of semi-hydro. Since there is no soil involved, the risk of soil-borne pathogens, pests, and fungi attacking your plant is significantly reduced. However, it’s important to note that pH and nutrient levels must be actively regulated in semi-hydro, as the plant’s roots are exposed to the water and can absorb too much or too little of certain elements.
Overall, if you’re looking for a low-maintenance and innovative way to grow your Calathea, consider giving semi-hydro a try.
Now that you know the benefits of semi-hydroponic growing for your Calatheas, let’s talk about the pot options available. While any pot with drainage holes will work, some options are more suitable than others. When choosing a pot, consider both decorative options and size considerations.
