What Causes the Leaves of a Kalanchoe to Turn Yellow
This article introduces the reasons for the yellowing of Kalanchoe leaves and the causes of yellow leaves and solutions for this problem in the field of green plants and flowers. Next, the editor will introduce to the netizens.
Kalanchoe is one of the species of the daffodil genus, with tall plants and bright green leaves. The petals and corona are both golden yellow. There are many reasons for the yellowing of Kalanchoe leaves. If it is caused by root rot, the plant needs to be removed from the potting soil, the rotting roots cut off, and then replanted. If it is caused by excessive fertilization, a large amount of water can be added to the pot to dilute the fertilizer in the soil. If it is caused by diseases and pests, the yellow leaves need to be cut off promptly, and then the plant should be sprayed with a special medicine. Next, I will tell you about the reasons for the yellowing of Kalanchoe leaves and the specific solutions.
1. Root Rot
If the Kalanchoe has not been repotted for a long time, excessive watering or overly compacted soil can cause waterlogging in the potting soil, leading to root rot. If yellow leaves appear on the plant, check if the plant's roots have rotted. If rot has already started, the plant needs to be removed from the original potting soil, the attached old soil removed, the rotting roots cut off, and then planted in fertile and loose growing soil for care.
2. Over-fertilization
Kalanchoe is not tolerant of fertilizer. If excessive fertilization or too concentrated fertilizer is used, it can lead to fertilizer damage and cause yellowing of the leaves. If the fertilizer damage is severe, new potting soil needs to be used. If it is not very serious, the fertilizer can be diluted by watering heavily.
3. Disease Infection
If the plant is in a high humidity and poorly ventilated environment for a long time, it is prone to disease infection, which can cause yellowing of the leaves. The yellowed branches and leaves need to be cut off first, and then disinfected with diluted disinfectant. Spray once every 7-10 days until the plant recovers.
4. Excessive Sunlight
Although Kalanchoe enjoys sunlight, prolonged exposure to strong sunlight can cause leaf burn, leading to yellowing and withering of the leaves. The plant needs to be moved to a shady and well-ventilated area for care, during which time, water should be poured moderately, and it will recover slowly.
5. Normal Phenomenon
In the process of raising Kalanchoe, if the bottom leaves turn yellow while the top leaves show no abnormalities, this is a normal metabolic process and requires no further treatment.
The above is the full content of why the leaves of Kalanchoe turn yellow, the causes of yellow leaves, and the solutions. I hope it can help you and also hope that everyone will come to see more experience and common sense of green plants and flowers!
