The Kalanchoe is getting smaller and smaller. Why doesn't it grow new leaves? What should I do?

Kalanchoe is very common in life. Because of its fragrant flowers and good meaning, many people will keep one or two pots at home. However, some Kalanchoe are getting smaller and smaller. Why is it that Kalanchoe is getting smaller and smaller? What should I do if Kalanchoe never grows new leaves? The following editor will explain them one by one, hoping to help you.

Why does the longevity flower get smaller as it grows?

The Kalanchoe at home is getting smaller and smaller, which is due to lack of fertilizer, lack of sunlight, and malnutrition. In the hands of seedling merchants, Kalanchoe is grown with large amounts of fertilizer and water. The fertilizer used by merchants naturally has large leaves, and the leaves are also large after being exposed to the sun in the summer.

What should I do if the Kalanchoe never grows new leaves?

1. Still in dormancy

If the local weather is still relatively hot, the old leaves of the Kalanchoe are dull and lack luster, which means that it is still in the dormant period and has not awakened. It is normal that the metabolism is slow and it does not grow new leaves. Take good care of it and wait for the weather to cool down. When the dormant period ends, the Kalanchoe will start to grow new leaves and new buds.

2. Lack of fertilizer

It takes power for Kalanchoe to grow new leaves. When there are sufficient nutrients and the temperature is suitable, it will naturally grow new leaves and sprout new buds. If you do not repot the Kalanchoe for a long time or do not fertilize it for a long time, it will stop growing due to insufficient nutrients. Another symptom of Kalanchoe not growing due to lack of fertilizer is that the old leaves below will become thinner and yellower. In this case, fertilize in time, mainly with nitrogen fertilizer, once every half a month, and fertilize twice in a row, and the Kalanchoe will enter a growth state.

3. A small amount of root rot

If the Kalanchoe is not properly maintained in summer, resulting in root damage or a small amount of root rot, it will be difficult for the Kalanchoe to grow even if the temperature is right and there is no lack of fertilizer. A small amount of root damage will not temporarily cause the leaves of the Kalanchoe to turn yellow and rot. The manifestation is slow growth, dull leaves, soft or wrinkled leaves. If the Kalanchoe is well maintained and new roots grow, new leaves will also sprout.

How to cultivate the palace lantern Kalanchoe

First of all, we need to pay attention to the temperature. The most suitable growth temperature is 15~25℃. If it exceeds 30℃, it will grow slowly or even stop growing. Therefore, in order to promote its growth in summer, certain shading measures can be taken. Of course, if you don't want the plant to be too tall, you can also not take shading measures and prevent it from growing in summer. When entering winter, make sure the temperature is above 10℃, otherwise the growth will stagnate; below 8℃, the leaves will turn red, and below 0℃, it will freeze to death.

Secondly, it is the management of fertilizer and water. Fertilization is different in different growth stages. During the planting period, nitrogen fertilizer is mainly used, and fertilizer is applied 2 to 3 times a month. After the flowers fade, fertilizer is also needed. At first, liquid fertilizer mainly composed of nitrogen is applied to promote its rejuvenation. After that, 0.2% potassium dihydrogen phosphate solution can be applied every month.

Finally, we have to mention the diseases that the palace lantern kalanchoe will face, such as powdery mildew and leaf blight. For these two diseases, mancozeb wettable powder can be sprayed.
