Hey there, plant lovers! As a supplier of calathea plants, I get asked a ton of questions about these gorgeous green beauties. One question that pops up more often than you'd think is, "What is the ideal temperature for a calathea plant?" Well, let's dive right in and find out!


First off, calathea plants are native to the tropical regions of South and Central America. That means they're used to a warm and humid environment. In the wild, they thrive under the canopy of larger trees, where they're protected from direct sunlight and enjoy a relatively stable temperature.
So, what does that mean for us calathea plant parents? Generally speaking, calathea plants prefer temperatures between 65°F and 80°F (18°C to 27°C). This range mimics their natural habitat and allows them to grow and thrive. If the temperature drops below 60°F (15°C), your calathea might start to show some signs of stress. The leaves could curl up, turn yellow, or even start to drop off. On the other hand, if the temperature gets too hot, above 85°F (29°C), the plant can also struggle. It might wilt, and the leaves could develop brown edges.
Let's talk about why temperature is so important for calathea plants. These plants have a unique way of regulating their water intake. Their leaves have tiny pores called stomata, which open and close to let in carbon dioxide and release oxygen. When the temperature is just right, the stomata function properly, allowing the plant to photosynthesize effectively. But if the temperature is too high or too low, the stomata can malfunction, leading to problems with water balance and overall plant health.
Another reason temperature matters is because it affects the plant's metabolism. Just like us, plants have a metabolic rate that determines how quickly they grow and develop. In the ideal temperature range, the calathea's metabolism is in full swing, allowing it to produce new leaves, roots, and flowers. If the temperature is outside of this range, the metabolism slows down, and the plant might stop growing or even go into a state of dormancy.
Now, let's get a bit more specific. Different varieties of calathea plants might have slightly different temperature preferences. For example, the Calathea Ornata Plant is known for its beautiful striped leaves. This variety tends to do best on the warmer end of the temperature spectrum, around 70°F to 80°F (21°C to 27°C). On the other hand, the Calathea Makoyana, with its delicate, lacy leaves, can tolerate slightly cooler temperatures, as long as they don't drop below 65°F (18°C).
So, how can you make sure your calathea plant is in the right temperature range? Here are a few tips:
- Find the right spot in your home: Place your calathea away from drafty windows, doors, and heating or cooling vents. These areas can cause sudden temperature changes, which are stressful for the plant. A room with consistent temperature and some natural light is ideal.
- Use a thermometer: Keep a thermometer near your calathea to monitor the temperature. This way, you can quickly adjust if it starts to get too hot or cold.
- Adjust the temperature seasonally: In the winter, you might need to move your calathea to a warmer spot or use a space heater to keep it cozy. In the summer, make sure it's not in a room that gets too hot, especially if you don't have air conditioning.
- Consider a humidifier: Since calathea plants love humidity, using a humidifier can help create a more comfortable environment. The added moisture in the air can also help regulate the temperature around the plant.
