Beyond their undeniable visual appeal, Calathea plants have become increasingly popular among indoor gardeners for a reason. They offer a touch of the tropics to any space, and with proper care, these leafy wonders can thrive for years to come.
In this blog post, we’ll delve into everything you need to know about bringing Calatheas into your home. By the end, you’ll be equipped with the knowledge to confidently care for your Calathea and witness its vibrant foliage flourish indoors.
What Is Calathea?
As a gardening enthusiast, I’m often drawn to plants that spark conversation. Calatheas are one such genus, guaranteed to turn heads with their captivating foliage. These tropical perennials, native to the rainforests of South America, boast a remarkable characteristic – stunning leaves adorned with intricate patterns, stripes, and splashes of color. Imagine velvety greens splashed with pinks like the Calathea Roseopicta, or the zebra-like stripes of the Calathea Zebrina. It’s no wonder they’ve earned nicknames like “Peacock Plants” and “Prayer Plants.”
There are over 60 Calathea varieties, each with unique leaf shapes and color combinations. Some varieties, like the Calathea Lancifolia, have elongated, lance-shaped leaves, while others, like the Calathea Orbifolia, boast round, almost circular foliage. Finding your perfect Calathea is part of the fun!
While their beauty is undeniable, Calatheas also thrive in moderately moist environments, mimicking their native rainforest habitat. This makes them ideal for terrariums or bathrooms with good air circulation. Keep in mind that these leafy wonders prefer filtered light as opposed to harsh, direct sun. So, when it comes to choosing a spot for your Calathea, think of dappled sunlight filtering through a lush canopy.
How to Plant Your Calathea
Now that you’re captivated by the allure of Calathea, let’s get down to the practical side of bringing one into your home. The good news is that planting Calathea isn’t complicated, but choosing the right environment sets the stage for future success.
Finding the Perfect Pot
Drainage is key for Calathea, as they dislike soggy roots. Select a pot with drainage holes at the bottom. While plastic pots are lightweight and affordable, terracotta pots offer better breathability, allowing excess moisture to evaporate.
When choosing a pot size, opt for one that’s just 1-2 inches wider than the root ball of your Calathea. This allows for growth while preventing excessive soil that can stay wet for too long.
The Ideal Soil Mix
Mimic the rainforest floor by using a well-draining, airy potting mix. A good option is a mixture of equal parts potting soil, perlite, and orchid bark. Perlite improves drainage, while orchid bark provides aeration and helps retain moisture without becoming waterlogged.
Planting with Care
- Prepping the Pot: If using a new pot, consider soaking it in water for a few minutes to enhance drainage. Place a well-fitting drainage tray underneath the pot.
- Transplanting or Repotting: Carefully remove your Calathea from its current pot. If it’s rootbound (roots circling tightly around the pot), gently loosen them with your fingers. Place the plant in the new pot, ensuring the top of the root ball sits slightly below the pot rim.
- Watering Wisely: Fill the pot with your chosen potting mix, gently tamping it around the root ball to eliminate air pockets. Water thoroughly until water runs out of the drainage holes. Discard any excess water that accumulates in the tray. Remember, it’s better to be underwater than overwater your Calathea.
Top Tip: Consider using filtered or rainwater when watering your Calathea, as they are sensitive to minerals often found in tap water.
How to Grow Your Calathea
With your Calathea planted and settled in its new home, let’s explore how to nurture its captivating beauty. While these plants aren’t overly fussy, understanding their preferences will ensure they flourish indoors.
Light Matters
Remember those stunning rainforest origins? Calatheas prefer dappled, indirect sunlight. Direct sun can scorch their delicate leaves, while overly low light can hinder growth. A bright spot near an east-facing window is ideal.
Alternatively, you can mimic dappled light by placing your Calathea a few feet back from a south or west-facing window. Observe your plant – if the leaves start to curl or lose their vibrant colors, it’s likely receiving too much or too little light.

Tropical Temperament
Think warm and steamy when it comes to temperature. Calatheas thrive in temperatures between 70 and 85 degrees Fahrenheit. Avoid placing them near cold drafts or air conditioners, as sudden temperature fluctuations can stress the plant.
Humidity is Key
Here’s where those rainforest vibes come into play again. Calatheas crave humidity levels between 50% and 80%. Dry indoor air can cause the leaves to crisp or curl. Grouping your Calathea with other humidity-loving plants can help create a mini-humid microclimate. Alternatively, you can use a pebble tray (fill a tray with pebbles and water, placing the pot on top, ensuring the bottom of the pot doesn’t touch the water) or invest in a humidifier.
Fertilizing (Not Really)
Calatheas are not heavy feeders. During the growing season (spring and summer), a balanced, diluted liquid fertilizer applied once a month is sufficient. Always follow the manufacturer’s instructions and avoid overfertilizing, which can damage the roots. During fall and winter, when growth slows, you can hold off on fertilizing altogether.
Pest Patrol
While relatively pest-resistant, Calatheas can occasionally attract spider mites or mealybugs. Regularly inspect your plant, and if you notice pests, address them promptly using organic methods like insecticidal soap or neem oil spray.
Care Tips for Your Calathea
Now that we’ve established the foundational care for your Calathea, let’s delve into some techniques to keep it looking its best year-round.
Watering
Remember, underwatering is preferable to overwatering with Calathea. The key is to find a watering routine that keeps the soil consistently moist, but not soggy. Sticking your finger into the soil about an inch deep is a good way to check moisture levels.
If the top inch feels dry, it’s time to water. Thoroughly drench the soil until water runs out the drainage holes, then discard any excess water that accumulates in the tray.
Pruning for Perfection
Calatheas don’t require extensive pruning, but you can trim away any brown, damaged, or discolored leaves to maintain a neat appearance. Use sharp, sterilized pruning shears to make clean cuts just above a node (the bump where a leaf or stem joins the main plant body). This will encourage bushier growth.
Propagation
Feeling adventurous? Calatheas can be propagated by division when repotting. Simply divide the root ball carefully, ensuring each new section has healthy roots and leaves. Pot them up in appropriately sized containers with fresh potting mix and care for them like your mature Calathea.
Seasonal Shifts
While Calatheas aren’t too fussy, there are slight adjustments you can make throughout the year to optimize their care. During spring and summer, the active growing season, maintains consistent moisture, fertilize monthly, and provide bright, indirect light.
As fall approaches, reduce watering frequency and ease off on fertilizing as growth slows. Keep in mind that dry winter air can be especially challenging for Calatheas. Increase humidity levels using the methods mentioned earlier, and be mindful of keeping them away from heating vents.
Common Calathea Issues
Yellowing Leaves: This can be a sign of both overwatering and underwatering. Overwatering leads to root rot, which disrupts the plant’s ability to absorb nutrients. Underwatering simply deprives the plant of moisture. Check the soil moisture – if soggy, ease off on watering and repot if necessary. If dry, give your Calathea a good drink.
Leaf Curling: This can be caused by a few factors. Inconsistent watering, with periods of both underwatering and overwatering, can lead to curling leaves. Incorrect light can also be a culprit – too much direct sun can scorch the leaves, while insufficient light can cause them to curl inwards. Ensure your Calathea receives bright, indirect light and maintains consistent moisture levels.
Browning Leaf Edges: Dry indoor air is the most common reason for brown leaf edges on Calathea. Increase humidity levels around your plant using a pebble tray, or humidifier, or grouping it with other humidity-loving plants. In some cases, mineral build-up from tap water can also cause browning. Consider using filtered or rainwater when watering.
Drooping or Wilting: This is a general sign of stress and can be caused by various factors. Overwatering is a frequent culprit, as it weakens the root system. Check the soil moisture and adjust your watering routine accordingly. Underwatering, excessive heat, or very dry air can also lead to wilting. Ensure proper light and temperature, and address humidity levels if necessary.
Calathea FAQs
Q1. How often should I water my Calathea?
There’s no one-size-fits-all answer, as watering frequency depends on factors like pot size, light conditions, and even the season. However, the key is to avoid extremes. Stick your finger into the top inch of soil – if it feels dry, it’s watering time. Thoroughly drench the soil until water runs out of the drainage holes, then discard any excess water. Remember, underwatering is generally better than overwatering for Calathea.
Q2. Can Calathea plants tolerate low light?
While Calatheas aren’t light-hungry, they do prefer bright, indirect light. Think of dappled sunlight filtering through a tree canopy. Very low light levels can hinder growth and cause the leaves to lose their vibrancy. However, unlike some plants, Calatheas won’t necessarily die in low light. They might just appear a little less enthusiastic.
Q3. How do I increase humidity for my Calathea?
Those rainforest roots crave moisture! Here are a few ways to boost humidity around your Calathea:
- Pebble tray: Fill a shallow tray with pebbles and water. Place your Calathea pot on top, ensuring the bottom of the pot doesn’t touch the water directly. As the water evaporates, it increases humidity levels around the plant.
- Grouping: Placing your Calathea close to other humidity-loving plants creates a mini-humid microclimate.
- Humidifier: This is a great option, especially during dry winter months. Just be sure to use clean, distilled water to avoid mineral build-up.
Q4. Is Calathea toxic to pets?
The good news for pet owners is that Calatheas are generally considered non-toxic to both cats and dogs according to the American Society for the Prevention of Cruelty to Animals (ASPCA). However, it’s always best to keep houseplants out of reach of curious pets to avoid any potential stomach upset from nibbling on leaves.
