Florists growing Kalanchoe often encounter a problem such as yellowing of foliage in a flower. There can be many reasons for this. Why does the leaf doctor turn yellow at the home doctor, how to cure the plant, and is it possible to prevent the appearance of a similar problem - in this review.
Features of Kalanchoe Care
Compliance with all the rules of care allows the plant to grow normally, have succulent, bright green leaves and bloom. Kalanchoe is not finicky in this regard. He needs very little attention:
- Reasonable watering. Excess moisture damages the plant. It’s more correct to add a little water than to wet excessively. The flower is able to store moisture for 3 days. In the cold season, watering is reduced.
- Favorable temperature. For Kalanchoe, this is + 18 ... + 20 ° C. The flower does not tolerate heat, but a small coolness is normal.
- Adequate lighting. It is better to place it in a bright place, but priteniv from direct sunlight. Additional lighting will be required only during the flowering period.
- Low humidity. Like waterlogging of the soil, high humidity leads to the appearance of fungal diseases and mold.
- Suitable soil. A home doctor needs infertile soil with sand and peat.
- Moderate top dressing. In the flowering phase, fertilize the flower once a week with minerals.
Propagate the flower by scion, rooting them in separate containers with wet sand.Did you know? Kalanchoe is a unique plant that can purify the air of pathogenic microbes, influenza virus and other harmful microorganisms.
Why do Kalanchoe leaves turn yellow and dry
This flower belongs to fairly persistent succulents, but it can also cause problems. Basically, this trouble happens due to a violation of the rules of maintenance or care.
Incorrect landing technology
Lifeless and yellowed leaves may indicate a violation of planting technology. Like every plant, Kalanchoe does not tolerate when the integrity of an earthen coma is violated during transplantation. Then the smallest roots that are actively involved in the process of moisture absorption suffer.With global soil replacement, small roots easily break off and are difficult to regenerate, so replanting with a complete replacement of the substrate is called a hard transplant and is rarely used. Basically, the plant is transferred to a new place by transshipment or simply limited to replacing the topsoil.
Also, when transplanting, the size of the new capacity is often taken too large. In this situation, the leaves also dry out and turn yellow. The explanation is simple: the free substrate is not occupied by the roots, and excess moisture accumulates in it. Between humidifications, the soil does not have time to dry out, which entails rotting of the roots.Did you know? If you grow Kalanchoe in a shaded place, it accumulates more healing and nutrients.
If, as a result of a transplant, the leaves turn yellow, the following actions should be performed:
- Normalize watering. Zircon can be added to the water (every 2 irrigation). In this case, the rule is observed: the lower the temperature, the less moisten the soil.
- Increase air humidity.
- Provide bright light. In winter, the flower has enough artificial lighting, and in summer it is better to place it in the western or eastern directions, protecting from direct exposure to the sun.
Inappropriate location
Excessive illumination or, conversely, a lack of light negatively affects the state of Kalanchoe. Due to improper placement, the foliage turns yellow and curls. The flower should be grown in shaded places.
If the bush turns yellow above, it does not have enough light. Then it is better to place the plant in a more illuminated area, while protecting it from exposure to sunlight.Important! Not all varieties of Kalanchoe can withstand direct sunlight.
If the leaf blade turns yellow along its entire length, this indicates an excess of light. Accordingly, the pot is placed in a shaded place.
Non-compliance with the conditions of detention
Inconsistency of the external environment also leads to yellowing of the foliage. So, one of these reasons is overdried air. Most often this happens when the flower is placed close to the heating appliances. High temperatures can also cause yellowing of foliage. Although the flower looks healthy, its leaves turn yellow, but do not dry. In addition, yellowing of the leaves may occur as a result of infection of the plant or attack of harmful insects. Many diseases initially appear precisely in the change of the leaf plate: yellowing, twisting, wilting and falling.
But minor flaws on the leaves or sticky spots can indicate an attack of pests. Feeding on the juice of the flower, parasites reduce the immunity of the plant and cause its death.
Stagnant air is also not very well reflected in the appearance of Kalanchoe. This flower loves fresh air, so in warm times it is recommended to take it to a balcony or a veranda.Important! Many pests are carriers of infections.
Irrigation
This mistake is the most common and can provoke not only yellowing of the foliage, but also lead to the death of the plant.
By its nature, Kalanchoe belongs to succulents, therefore it should receive a little moisture and quite rarely. If the soil is moistened often and abundantly, the roots will rot and the leaves turn yellow and become sluggish.In order to escape from yellowing, it is recommended to transplant a flower, while removing all the roots in which the process of decay is noticed. In the future, this watering regime is recommended: the top layer dries up, and only after 5 days you can water the flower. At the same time, the soil is moistened only slightly, without zeal.
Feeding mistakes
Excess nutrients are just as dangerous as their deficiency. Some in anticipation of flowering Kalanchoe begin to generously sprinkle fertilizer. The flower, in turn, dutifully absorbs everything. That's just the leaves react negatively to such an abundance.
The main sign of an excess of fertilizers is yellow foliage, which later becomes brown. A red border and brown wet spots appear on the sheet plate. The flower has an unhealthy appearance and ceases to bloom. Around formed a lot of painful shoots, the tops rot. Output: urgently stop applying fertilizer.
It is better for the plant to give top dressing once a month, reducing by 2 times the rate indicated on the package. Such an amount will always be beneficial, and surplus will only do harm.Important! Kalanchoe, like all succulents, adapted to live in harsh environmental conditions.
In order not to miss, you can use the so-called "long-playing" feeding. They are simply placed in a pot, and the flower itself takes as much as it needs.
Do not forget that plants are living organisms, so they are characterized by the aging process. Kalanchoe leaf plate may turn yellow from old age. On this occasion, do not worry.

Preventative measures
So that Kalanchoe does not hurt and has a healthy appearance, it is necessary to adhere to tips for caring for it and observe the conditions of detention, avoiding drafts, sudden changes in temperature, air drying or waterlogging of the soil.Basically, the prevention of yellowing of the leaves is as follows:
- Avoid exposure to sunlight. On sunny days, it is advisable to close the window with a curtain.
