Did you know that Calathea plants, also known as prayer plants, are not only beautiful but also great for indoor gardening? With their stunning foliage and unique patterns, Calathea plants can add a touch of elegance to any space.
In this comprehensive guide, we will walk you through everything you need to know about growing Clathea plants indoors. From the ideal growing conditions to propagation techniques, we’ve got you covered.
Key Takeaways
- Adjust temperature and humidity levels to 65-75°F and 50-60% respectively
- Place the plant in bright, indirect light and avoid direct sunlight
- Water every 1-2 weeks, keeping the soil evenly moist but not waterlogged
- Use well-draining soil and maintain a pH level between 6 and 6.5
Growing Conditions
These tropical plants thrive in warm, humid environments, so it’s important to provide them with the right conditions. Aim for a temperature between 65-75°F (18-24°C) and a humidity level of 50-60%.
To monitor the humidity, you can use a hygrometer. Additionally, you should choose the right type of soil for your Calathea plants. A well-draining soil mixture that retains moisture is ideal.
You can also consider using a peat-based soil mix, as Calathea plants prefer slightly acidic soil. Lastly, selecting the right pot is essential. Opt for a pot with drainage holes to prevent waterlogging, and ensure it is large enough to accommodate the plant’s root system.
| Temperature | Humidity | Soil Type |
|---|---|---|
| 65-75°F | 50-60% | Well-draining, slightly acidic soil |
Remember to adjust the temperature and humidity levels in the room to create the perfect environment for your Calathea plants to thrive.
Light Requirements
Ensure that your Calathea plants receive adequate light by placing them in a bright, indirect light location. Calathea plants thrive in moderate to bright light conditions, but direct sunlight should be avoided as it can scorch the leaves.
Place your Calathea plant near a window with a sheer curtain to filter the light or in a well-lit room away from direct sunlight. If the leaves start to fade or curl, it’s an indication that the plant isn’t receiving enough light.
Water Requirements
Calathea plants, native to humid jungles, have specific watering requirements to thrive. To ensure their well-being, it’s essential to keep their soil consistently moist but not waterlogged. Check the top 1-2 inches (about 2.5-5 cm) of soil and water when it feels dry at this depth. Overwatering should be avoided as it can lead to root rot. Proper drainage in the pot is crucial for preventing water from accumulating at the bottom.
Ideally, use distilled water, rainwater, or water that has been allowed to sit for 24 hours to dissipate chlorine. Some experts recommend using lukewarm water to mimic the natural warm water these plants encounter in their tropical habitats. Adjust the watering frequency according to the season, watering more often during the growing season (spring and summer) and reducing it in the winter when the plant is less active.
Soil Requirements
Make sure the soil for your Calathea plant is well-draining to prevent waterlogged roots. Calathea plants prefer a loose, well-aerated soil that allows water to drain freely. This is crucial to avoid root rot and other fungal diseases.
To achieve proper drainage, you can mix equal parts of peat moss, perlite, and potting soil. This will create a light and airy soil mix that promotes healthy root growth. Additionally, Calathea plants thrive in slightly acidic soil with a pH level between 6 and 6.5.
It’s also important to note that Calathea plants are sensitive to salts and minerals, so it’s best to use filtered or distilled water for irrigation. By providing well-draining soil, you can ensure the overall health and longevity of your Calathea plant.
Temperature and Humidity Requirements
Maintain the proper temperature and humidity levels in your indoor environment to meet your Calathea plant’s requirements for optimal growth. Calathea plants, such as Calathea Exotica and Calathea Lutea, are tropical plants that thrive in warm and humid conditions. They are sensitive to temperature fluctuations and low humidity levels, which can lead to leaf curling and browning. To ensure their well-being, it is essential to provide them with the right conditions.
Here is a table outlining the temperature and humidity requirements for Calathea plants:
| Temperature | Humidity |
|---|---|
| 65-75°F | 50-70% |
To maintain the ideal temperature, keep your Calathea plants away from drafts and cold windows. You can use a thermometer to monitor the temperature accurately. As for humidity, you can increase it by placing a tray of water near your plants or using a humidifier. Proper temperature and humidity levels will promote healthy growth and vibrant foliage in your Calathea plants.
Fertilizer Requirements
You should consider using organic fertilizers, such as compost or fish emulsion, and regularly feed your Calathea plants to meet their nutrient requirements and promote healthy growth. Calatheas are tropical plants that thrive in nutrient-rich soil, and fertilizing them is essential for their overall well-being.
Organic fertilizers are recommended as they provide a slow-release of nutrients and are less likely to burn the plant’s sensitive roots. When feeding your Calathea, it’s important to follow the instructions on the fertilizer packaging to avoid over-fertilization, which can lead to root damage.
Regular fertilization will help your Calathea plants stay strong and resistant to common pests, such as spider mites and aphids. Additionally, if you’re starting Calathea plants from seeds, it’s important to provide them with a balanced fertilizer to support their initial growth.
Propagation, Pruning, and Seed Starting
When propagating Calathea plants, it’s important to carefully choose healthy stems to ensure successful growth. Here are some key points to consider when propagating, pruning, and starting seeds for Calathea plants:
Propagation
Division: Gently separate the plant into multiple sections, making sure each section has a healthy stem and root system.

Pruning Techniques
Remove any yellow or brown leaves to maintain a healthy appearance and prevent the spread of diseases.
Trim back leggy or overgrown stems to encourage bushier growth.
Pinch off faded flowers to redirect energy into new growth
Seed Starting
Collect ripe seeds from the plant and sow them in a well-draining potting mix.
Cover the seeds lightly with soil and keep them moist until germination occurs.
Provide a warm and humid environment to promote successful sprouting.
Potting, Repotting, and Overwintering
To ensure the health of your Calathea plants, repot them every 1-2 years to refresh the soil and provide them with enough space to grow. Repotting allows you to examine the root system and make sure it’s healthy.
Choose a pot that’s one size larger than the current one, as Calatheas prefer snug spaces. Fill the bottom of the new pot with fresh, well-draining potting mix.
Gently remove the plant from its current pot, being careful not to damage the roots. Loosen the root ball and place it in the new pot, making sure it’s centered. Fill the remaining space with potting mix, firming it gently around the roots.
Water the plant thoroughly, allowing the excess to drain. Place the repotted Calathea in a shady spot for a few days to minimize stress.
With proper repotting, your Calathea plants will thrive and bring beauty to your indoor space.
Common Pests, Blooming, and Common Problems
During the blooming season, regularly inspect your Calathea plants for common pests like spider mites and aphids. These pests can be detrimental to the health and appearance of your plants.
Spider mites are tiny arachnids that feed on the sap of the leaves, causing discoloration and deformities. They’re often found on the undersides of the leaves and can be identified by their fine webbing.
Aphids, on the other hand, are small insects that suck the sap from the plant, leading to stunted growth and yellowing leaves. They can be found on the stems and leaves of the plant.
To control these pests, you can use organic insecticidal soaps or neem oil. It’s important to treat the affected plants as soon as possible to prevent further damage.
Regularly cleaning the leaves with a damp cloth and providing proper airflow and humidity can also help prevent infestations.
