Calathea ornata, also known as purple prayer plant or purple-leaf calathea, is a common indoor foliage plant. Its leaves are colorful and unique, making it a favorite among plant enthusiasts. Many plant enthusiasts encounter the problem of curled leaves when caring for Calathea ornata. This article will reveal the reasons for curled leaves on Calathea ornata and provide corresponding care tips to help you grow a healthy and beautiful plant.
Reasons for Curled Leaves on Calathea Ornata1. Insufficient Water
Calathea ornata thrives in a humid environment. If not watered in time, its leaves are prone to curling. This is because water deficiency causes the leaf cells to lose water, which in turn leads to leaf curling.
2. Overwatering
Conversely to insufficient water, overwatering can also cause the leaves of Calathea ornata to curl. This is because overly moist soil prevents the roots from breathing properly, leading to root rot, which in turn affects leaf growth.
3. Insufficient Light
Calathea ornata prefers indirect light. If it is kept in a dark environment for a long time, its leaves are likely to curl. This is because insufficient light slows down plant growth, causing the leaf color to fade and the shape to become unattractive.
4. Low Air Humidity
Calathea ornata thrives in a humid environment. If the air humidity is low, the leaves are prone to curling. This is because dry air causes the leaves to lose water, leading to curling.
5. Pests and Diseases
Calathea ornata is susceptible to pests and diseases, such as leaf spot disease and aphids. These issues can cause leaves to curl and turn yellow, and in severe cases, may even lead to leaf drop.
Care Tips for Curled Leaves on Calathea Ornata1. Control Watering
Keep the soil slightly moist, avoiding both overwatering and underwatering. Generally, water once or twice a week, adjusting the frequency based on the season and climate.
2. Increase Light
Place Calathea ornata in a location with plenty of indirect light, avoiding direct sunlight. In winter, you can slightly increase the light duration to promote plant growth.
3. Increase Air Humidity
Use a humidifier or mister to increase indoor air humidity. You can also place the Calathea ornata on a plant stand or a saucer with pebbles to increase moisture evaporation from the soil and raise the humidity around the plant.
4. Prevent Pests and Diseases
Regularly inspect the plant and promptly address any pests or diseases. You can use pesticides or biological control methods, such as introducing predatory insects.
5. Prune Leaves
Timely prune diseased and weak leaves to keep the plant tidy. Pruning branches appropriately can also promote new growth.
The reasons for curled leaves on Calathea ornata are varied. During the care process, it is important to pay attention to factors such as water, light, and air humidity. By mastering the correct care techniques, you are sure to grow a healthy and beautiful Calathea ornata. I hope this article is helpful to you.
