 The leaves on your calathea may be curling for many different reasons. So let's just talk about these reasons and get to the bottom of this so you can fix it for your plant. The first possible reason for curly leaves on your calathea is under watering. Remember, the calathea mosaica likes the soil to be moist at all times. And not that I'm saying moist but not wet. We don't want to overwater our plant. But yes, we want to make sure that the soil is moist at all times. So what I would recommend is that you have a stable watering schedule. I usually check twice a week and generally I water once a week during the growing season. In the winter, when the plant is a little bit more dormant, I don't water as often. But very important, I always check before I water. So I stick my finger in the soil until the second knuckle. And once I feel that the soil is drying out, then I water. Also, the quality of the water is very important for this plant which takes me to the next point. As a calathea, this plant is a little bit more sensitive to tap water. This is because depending on your location, tap water may have some chlorine or some salt or minerals that may be too harsh for your calathea mosaica. And if this is the case and you're using tap water, the leaves will curl and maybe also dry up a little bit on the edges like here. So yeah, it's very important that we use good quality water for this plant. In my case, the water in Berlin is really hard for my plants. So I usually filter it before using it to water them, especially in the case of the calatheas. Another thing that you can do is to leave the tap water in a bucket for about 24 to 48 hours. And during this time, the chemicals or at least some of the chemicals will evaporate, which will make the water less hard for your plant. But of course, you can also use the still water or rainwater just to make sure that it is okay for your plant. Okay, you guys, the third possible reason may be temperature. This plant comes from Brazil, so she likes stable, warm temperatures. This is usually between 18 to 20-something degrees Celsius or 25 or 27 degrees Celsius, but not higher than 30 degrees or lower than 18 degrees. So if you see that your plant has curly leaves and you know that it is actually in a place close to a window, for example, where you open the window and you have many cold drafts coming in, this may be a reason why your plant is not looking the healthiest. In that case, I would recommend that you move your plant to a warmer spot. Very important, don't place your plant close to heating vents. This is because of the next possible reason for curly leaves, which is lack of humidity. The calathea mosaica is a tropical plant, so they will be happy in high humidity levels. In my experience, I have seen that my calatheas will thrive only when they are at 50-60% humidity. So we don't want to place them close to a heating vent because the air there tends to be really dry. If you feel that your calathea is lacking humidity, one way to raise it is to put her on top of a humidity tray or you can put her close to a humidifier. And another way that you can do it is always placing your calatheas all together because these plants will help each other with humidity levels.
