The Correct Way to Water Green Apple Calathea
This topic elaborates on the correct watering method for Green Apple Calathea and the cultivation method of Double-line Calathea, as follows:
Many calathea enthusiasts lost their plants during last winter because of their poor cold resistance. The safest temperature to survive winter is consistently above 10 degrees Celsius; temperatures below 7 degrees Celsius can cause frostbite or even death, including the common Green Apple Calathea.
The Green Apple Calathea has relatively high aesthetic value, enjoying ample scattered light and higher air humidity. However, it does not like soil that remains consistently moist. If its roots are exposed to damp soil for a long time, it can easily contract root rot, making it even more challenging to cultivate than other calatheas.
The Green Apple Calathea is native to the region of Brazil in South America. It has particularly large leaves, with young leaves being bright green (mature leaves are white-green), and the veins are surrounded by dark green, making it a very attractive ornamental plant.
Flowers of Green Apple Calathea
If provided with a consistently warm and humid environment and ample scattered light, the Green Apple Calathea can bloom. The flowers are white and not very bright, with its leaves being more visually appealing.
1. Sunlight
To grow potted Green Apple Calathea successfully, the most crucial factor is the environment. It is a small plant that does not grow particularly tall. It enjoys ample scattered light and is averse to direct strong sunlight, growing naturally under trees in forests and prefers light filtered through trees and glass, avoiding direct sunlight.
The Correct Way to Water Green Apple Calathea
Too much direct sunlight can burn the leaves, causing sunburn and leaf scorch. Green Apple Calathea can tolerate low light conditions but should avoid overly dark places. It can occasionally be moved indoors for display, with at least 3-5 hours of scattered light daily.
2. Temperature
Green Apple Calathea prefers a warm and humid environment, with the best care temperature being between 20-28 degrees Celsius. The minimum care temperature should be above 10 degrees Celsius, avoiding frost. Watering should be controlled in cold temperatures.
Always place the Green Apple Calathea in a well-ventilated area, away from air vents, especially away from air conditioners and heaters.
3. Watering
Supplying water to the Green Apple Calathea is tricky, as too much water or drought can lead to poor growth. It prefers a cycle of moist and dry soil,不喜欢 soil that remains constantly moist. Generally, water should be added when the top 3-5 centimeters of soil are dry.
Once its root system is robust, many strong, fleshy roots will grow at the bottom. Excess water can lead to root rot. If there is a saucer under the pot, it must not accumulate water, and any water in the saucer should be emptied within half an hour.
Green Apple Calathea with Rotting Roots
If possible, water it with neutral or slightly acidic water (the best is rainwater; tap water can be stored in a container for a couple of days before use). It is sensitive to fluorine and chlorine compounds in tap water. Using tap water containing these compounds can easily lead to poor leaf condition, such as leaf tip burn (the water quality varies by region, and some places can use tap water directly without issues).
4. Humidity
Green Apple Calathea prefers humidity. If the environment is well-ventilated, maintaining more than 50% air humidity is essential. If the air is dry, a humidifier can be used nearby, or water can be sprayed in the form of mist, but avoid leaving water on the leaves, especially at the leaf center, as it can easily lead to rot.
