So, you need to place the plant pot in a place where the medallion plant can get a sufficient amount of filtered light.

For example: Place it near the north-facing window or install a curtain on a sunny window to block direct sunlight.

Temperature Range

The best temperature range for perfect calathea medallion plant care is between 65 to 80 degrees F.

The good news is we have our home temperature in this range which means no worries about the temperature.

Keep your plants away from the direct Air conditioner air and hot air of heating systems.

The lowest possible temperature for calathea medallion is 55 degrees F. Below this temperature, your medallion calathea plant will start dropping its leaves.

This results in permanent damage which cannot be reversed with any method.

If you set your plant pot outside in the spring and summer.

All tropical plants need high humidity to live. But this high humidity is not suitable for humans.

So, we need an air moisture level that is good for both humans and tropical jungle plants.

Keep the room humidity between 50% to 65 % for better health of your calathea medallion plants. In case the room humidity is on the lower side.

Then shift it to another room or follow the below practices to help your plant to increase room humidity.

Misting water

This an old technique in which we use a spray bottle and fill it with clean filtered water. Then spray the water on all the leaves. This technique is good where humidity is slightly lower than the recommended point.

Pebble tray

This technique helps to increase the humidity by 10 %. All you need to do is take a humidity tray, fill it with water and add some small rocks.

Then put the plant pot over it. The hot air will evaporate the water of the tray and this will add moisture to the air.

Keep the adequate water level in the tray to avoid low humidity levels.


This a professional and strong solution to low humidity. Buy any inexpensive plant humidifier and fill the reservoir with filtered water and turn it ON.

Place it next to the plant and it will increase the entire room humidity in a few hours (depending on the size of the humidifier).

There is another method where we put all the plants close to each other. But this method will not work in the case of calathea plants.

Fertilizing calathea medallion plants

Fertilize the medallion plants only in the spring and summer seasons.

These are the seasons when they grow rapidly and need a good amount of nutrients to make their stems, new leaves, etc.

Never mist nutrient water on the plant leaves. This will burn the beautiful leaves.

Note: You cannot speed up the growth of your medallion plant by supplying it with a high amount of nutrients.

Extra watering results in root rot.

When a grower intentionally or unintentionally overwaters a plant. This results in root fungus.

  • Take the plant out of its pot
  • Cut the infected parts of the roots with sharp shears.
  • Change the potting soil

Too much bright light is the second common reason. To save themselves from high bright light. Plants start folding their leaves.

To save your plants, immediately give enough water in case of underwatering.

Move plant pots to a less bright location and protect them from direct sunlight. In 7 to 10 days, you will see improvements in your plant health.
