Why Kalanchoe leaves turn yellow. What to do? Such a request is often introduced into the search engines by people who are too actively caring for their indoor flowers. Let's see why this happens.
Wrong watering
Most gardeners do not realize that Kalanchoe is a succulent. Water is poured with a generous hand, from the heart and often. They do not even give the soil in the pot a good dry. But the plant is quite able to do without watering for a long time. And the overflow leads to the strongest rotting of the roots. And if it is very simple to save the Kalanchoe from drought, the yellowing from overflow practically never recovers.
Signs. Leaves turn yellow throughout the plant, soft, watery. Kalanchoe itself looks depressed, often shoots bend under the weight of water inside the leaf plates.
What to do. Urgent save! The usual termination of watering, as recommended by some sources, will give nothing. The root system has already begun to rot. It is necessary to immediately stop this process, otherwise the plant will die.
To do this, Kalanchoe is pulled out of the pot, then the roots are thoroughly washed under a stream of warm water. Now you need to carefully trim all rotten, foul-smelling and dark in color. The slices are powdered with crushed activated charcoal, left to dry in the open air for at least an hour.
After that, Kalanchoe is transplanted into another soil and a new pot. In the old there may be many pathogenic bacteria.
In the future, strictly monitor the moderation of irrigation. Recommended procedure: the top layer of soil in the pot has dried, plus another 5 days. By the way, do not particularly zealous. The soil is only slightly moisturized. No need to wait until water flows from the drainage holes. Kalanchoe does not like this. Otherwise, the root system, like a pump, will absorb absolutely all the moisture. And unknowing owners will start watering the plant again when they see the dry earth in the pot. The circle closes, the leaves begin to turn yellow again.
Wrong lighting
Signs of lack of light.The leaves turn yellow, shrink. Shoots become thin and long as matches.
What to do. Kalanchoe is very fond of bright light. But not more than 10 hours a day. Therefore, the output of only 2:
- Artificially create a short light day, covering the Kalanchoe with an opaque material.
- Choose a place of detention where the duration of the lighting will be normal. For example, an oriental window sill.
By the way, if the Kalanchoe is already stretched out and turned yellow, then it will not be possible to save the shoots. They will not become a lush compact bush. They will have to be cut. Just do not throw away. These shoots are well rooted, so why not get a few new plants? Of these, then it will be possible to easily form a beautiful crown with proper care.
Dry air
The second most common cause of yellowing of leaves is in Kalanchoe, especially during the heating season. Few people think about how hot radiators affect the plant.
Signs. The tips of the leaves turn yellow on the whole plant, then they begin to dry out completely.
What to do.Humidify the air around Kalanchoe as often as possible. This can be done in several ways:

- Place a pallet with expanded clay, peat or sphagnum nearby. Constantly water them.
If you do not have the opportunity to provide Kalanchoe with normal moist air, then it is better to artificially enter it into a state of rest. Put in a cool place (+ 14-16 ° С), reduce watering. In this position, the plant can be no more than 2 months, well, then you have to come up with something with an increase in humidity. Otherwise, the tips of the leaves will turn yellow.

And it is better to rearrange the pot for the curtain. For example, on a table or a bedside table near the window. Then do not have to fence every day shading.
