Its leaves are large and face upward, as if praying. They have rose colored in the center. Talking about its leaves, they have dark green borders.

Apparently, Calathea roseopicta can grow up to 20 inches or 50 centimeters in height. This variety is known to not grow very tall and it is known to mature slowly. Actually, rather than tall, its leaves are broader. Usually, this plant is put in a 12 inch or 30 cm pot. When it is put in this kind of pot, it can show a wide range of colors. Aside from indoors, it can also be planted outdoors. It is usually planted in a pot and is being kept outdoors.
Calathea roseopicta is usually grown in a container and is placed outdoors, where it gets bright sunlight in the day and indirect light at night.

If you are planning to grow Calathea roseopicta in pots or containers or if you just started growing it, check out the following guide:
The best soil for Calathea roseopicta is the one that is fast draining. Apart from that, it also needs to have an adequate aerating structure. Having this kind of thing is really important to keep the roots supplied with oxygen at all times, even after a complete soaking. Keep in mind that it is a must for the soil to always be moist, similar to its origin in rainforest.
A standard potting soil can be used. Besides, you can also add perlite which is good to promote aeration. To get the best result, you can also add anywhere from a fifth to a third of a cup of perlite. Make sure to make the soil absorb the water quickly. If the water keeps on the surface of the soil, it is possible that the potting mix is too dense and not draining effectively. To fix the issue, you can add a coco coir amendment.
Calathea roseopicta likes damp soil but does not like standing in water. During the growing season, you can try watering a little bit a few times a week. Do it when you see the top of the soil dries off. To check the moisture levels, you can stick a finger into the soil. In the winter, please lessen the frequency of watering. During this time, water it once a week or less. You should read also how to care Calathea in the winter.
It should be noted that Calathea roseopicta is the kind of plant that does not tolerate direct sunlight. It is the reason why it should be placed in a place that has bright but indirect light. Contrary to popular beliefs, it is not good in very dark environments. While it is possible for this plant to survive in low light conditions, there is no way for it to thrive or produce new growth in such conditions.
If you want to place Calathea roseopicta indoor, you can place it on a windowsill. Another great option is close to a window that gets a lot of light during the day. It is said that the darker the leaves, the more light a plant requires to keep its amazing color. The plant can become greenish if it receives a little light. For those who are wondering the best places to put this plant, you can consider inside a bright room without intense light, 16-10 feet from a window facing north, west or east, and outside the reach of direct sunlight. In addition, you can also consider a place that has sufficient artificial illumination. In the winter, you are suggested to move the Calathea roseopicta to a sunny windowsill to compensate for the light as the number of daylight decreases in such a time.
Temperature and Humidity:
As a tropical plant, Calathea roseopicta cannot tolerate cold environments. The best temperature for it is between 64 and 75 degrees Fahrenheit or 18 and 24 degrees Celsius. If the temperature falls below 15 degree Celsius or 60 degree Fahrenheit, it will have a hard time. Try your best to avoid drastic changes for the plant as it is not good with it.
If you are wondering about the room temperature, it is actually fine for Calathea roseopicta. However, you have to avoid drafts, which can be done by keeping the plant away from the cold winter windows and AC. Besides, heaters are also the things that you have to keep them away from the plant.
While fertilizer is not required all year, it is still important for Calathea roseopicta. When generating new leaves, which are in the spring and summer, you can apply these supplements. Outside the times, do not feed the plant. Talking about fertilizer, it is divided into two: organic and inorganic. You can use the synthetic one as it is cheaper but still effective. If you want to use this, use only ¼ to ½ of the recommended amount.
As the Calathea roseopicta keeps growing, it might be needed for you to consider upgrading from the current pot to the new one. You can do it when it is becoming root bound. Usually, it happens every year or two. Make sure to repot it when the root balls of the plant become so dense and there is no room for growth in the soil. To check if it is pot bound, firstly, place two fingers around the base of the plant. Then, flip it over. After that, gently lift it out of the pot. Do not forget to refresh the old soil of the plant with the new one.
