If you’re looking for a houseplant that stops guests in their tracks, look no further than the calathea medallion. With its vibrant and patterned foliage, this plant is a living work of art for your home.
Its large, round leaves feature a stunning contrast of dark and light green, painted with a feather-like pattern that seems to glow. The undersides are a rich, reddish-purple, adding to its dramatic flair. But its beauty comes with a reputation for being fussy. Don’t worry, though—with a few simple tips, you can keep your calathea medallion thriving.
Calathea Medallion
This plant is part of the Marantaceae family, often called “prayer plants” because their leaves move. At night, the leaves rise up as if in prayer, and they lower during the day. This natural rhythm is fascinating to watch. The calathea medallion is native to the tropical rainforests of Brazil, which gives us all the clues we need for its care.
Ideal Light Conditions
Getting the light right is the most important step. In the wild, calathea medallions grow on the forest floor under the canopy of taller trees. This means they get dappled, indirect sunlight.
- Perfect Spot: A north or east-facing window is ideal. A few feet back from a west or south window with a sheer curtain also works well.
- Avoid Direct Sun: Direct sunlight will scorch the leaves, causing faded colors, brown spots, or crispy edges.
- Too Little Light: If the plant gets to little light, its growth will slow and those vibrant patterns will start to fade.
Watering: The Balancing Act
Watering is where most people stumble. This plant likes consistent moisture but absolutely hates soggy feet. Its roots can rot quickly in waterlogged soil.
- The Finger Test: Always check the soil before watering. Stick your finger about an inch deep. If it feels dry, it’s time to water. If it’s still damp, wait a day or two.
- Water Thoroughly: When you water, do so thoroughly until water runs out of the drainage holes. Let the pot drain completely—never let it sit in a saucer of water.
- Water Quality: Calatheas are sensitive to chemicals in tap water, like fluoride and chlorine. This can cause brown leaf tips. Use filtered, distilled, or rainwater for best results. You can also fill your watering can and let it sit out overnight so some chemicals evaporate.
Humidity: The Secret to Happy Leaves
This is the non-negotiable for vibrant and patterned foliage. Low humidity leads to crispy brown edges and unhappy plants.
- Target Humidity: Aim for 60% or higher.
- Easy Solutions: Group it with other plants, place it on a pebble tray with water, or use a humidifier nearby. A humidifier is often the most effective solution, especially in winter.
- Misting: Light misting can help, but it’s not a substitute for true ambient humidity. Avoid misting to much, as constantly wet leaves can invite fungal issues.
Soil and Fertilizer Needs
A well-draining, airy potting mix is essential. A standard houseplant soil is to dense on its own.
You can make a perfect mix by combining:
- 2 parts regular potting soil
- 1 part perlite or pumice
- 1 part orchid bark or coconut coir
This ensures moisture is retained but excess water drains away quickly.
For fertilizer, less is more. Feed your calathea medallion monthly during the growing season (spring and summer) with a balanced, water-soluble fertilizer diluted to half strength. Do not fertilize in fall and winter when growth slows.
Common Problems and Simple Fixes
Even with great care, you might see an issue. Here’s how to troubleshoot.
Brown Leaf Edges or Tips
This is the most common complaint. It’s usually caused by one of three things:
- Low humidity: Increase moisture in the air.
- Tap water: Switch to filtered or distilled water.
- Underwatering: Check your soil moisture routine more consistently.
You can trim the brown edges off with clean scissors, following the natural shape of the leaf.
Yellowing Leaves
Yellow leaves often point to overwatering. Check the soil! If it’s constantly wet, you need to adjust your watering schedule and ensure the pot drains well. Older leaves sometimes yellow and die off naturally; just pluck them off.
Curling or Drooping Leaves
This is typically a sign of thirst. Check the soil—if it’s dry, give it a good drink. The plant should perk up within a few hours. If the soil is wet and leaves are curling, root rot could be setting in.
Fading Leaf Patterns
If those stunning patterns start to dissapear, the plant is likely getting too much direct light. Move it to a shadier spot.
Repotting and Propagation
Calathea medallions don’t mind being slightly root-bound. Repot every 2-3 years, or when you see roots growing out of the drainage holes.
- Choose a pot only 1-2 inches larger in diameter than the old one. A pot that’s to big holds too much soil and can stay wet for to long.
- Gently remove the plant and shake off old soil.
- Place it in the new pot with fresh potting mix, filling in around the sides.
- Water thoroughly and return it to its usual spot.
The best time to repot is in spring or early summer. While repotting, you can propagate by division. Carefully separate a clump of stems and roots, ensuring each division has several leaves. Pot them up separately and keep them in a warm, humid spot as they establish.
FAQ About Calathea Medallion Care
Why are the leaves on my calathea medallion moving?
That’s completely normal! It’s called nyctinasty. The leaves rise at night and lower during the day, following light cycles.
Is the calathea medallion pet-friendly?
Yes! This plant is non-toxic to cats and dogs, making it a safe choice for pet owners.
How often should I water my calathea medallion plant?
There’s no set schedule. Always use the finger test to check soil moisture. It might be once a week in summer and every 10-14 days in winter.
Can I put my calathea medallion outside?
Only in warm, shady, and humid conditions (like a covered patio in summer). Never put it in direct sun, and bring it inside well before temperatures drop below 60°F.
What’s the best way to clean the leaves?
Gently wipe the leaves with a damp, soft cloth to remove dust. This helps the plant breathe and shows off its vibrant and patterned foliage. Avoid leaf shine products.
With it’s stunning looks, the calathea medallion is a rewarding plant to grow. Pay attention to its light, water, and humidity needs, and it will reward you with a spectacular display of color and pattern for years to come. Remember, consistency is key—once you find the right spot and routine, this tropical beauty will thrive.
