The leaves of a Chinese rose turn yellow and fall: why is this happening, and also why is a houseplant dropping buds and what to do in this situation?

Each of the gardeners, sooner or later, is faced with various plant diseases. One of these problems is yellowing of the leaves.

In our article we will talk about why the leaves turn yellow, and how to restore the flower to health. And we will not tell you about all the indoor colors, but about one specific one - the Chinese rose.

What kind of flower is it, why does it drop buds and what are the features of caring for this plant, we will talk further.

What is yellowing?

Chinese rose, it is also hibiscus, the plant is quite hardy. She stoically tolerates errors in care, but if they are not permanent. If the plant is constantly filled or not watered at all, then the plant will begin to die. His leaves will begin to turn yellow and fall off, then buds and flowers. And if you do not pay attention to it, he will die.

This is not about natural aging, but about the causes of yellowing in a young plant. When a plant loses its beauty for other reasons. Therefore, yellowing the leaves is a signal that the Chinese rose is not all right.

Why does this happen to a houseplant?

Partial yellowing of the leaves, with spots cause various reasons. Let's consider them in more detail.

Wrong pot

Important! For any flower, it is important to choose the right pot. It depends on how its root system will develop.

Is the correct pot easy to check? Pour the flower in the morning, and in the evening check the condition of the earthen coma in the middle of the pot. If the earth is dry, the dishes for it are small, we urgently transplant. Otherwise, the leaves will start to turn yellow, as the flower will try to reduce the evaporation of moisture, discarding excess leaves.

The new pot should be 1-2 cm in diameter larger than the previous one. Transplantation is carried out by transshipment so as not to injure the roots. The pot should have good drainage. The transplant is carried out in moist soil, watering begins on the third day.

If water constantly accumulates in the pan, the roots will begin to rot, yellow and fall leaves. This suggests that the capacity is large. As in the previous case, a transplant is needed. The plant, along with an earthen lump, is removed from the pot and checked for rot. If the rot has appeared, we remove it, and we dust the places of the slices with crushed charcoal. We transplant into a smaller pot and adjust the watering.

Errors of care

Chinese rose plant is tropical and does not like drafts. It must not be placed in the reach of fans and air conditioners. And while airing the premises, it is recommended to cover with a screen.
Incorrect lighting. This factor leads to the following consequences:
1. With a lack of lighting, a rose discards leaves, guided by the principle: fewer leaves, less light is needed.
2. With a lack of sunlight, the leaves turn yellow on the shaded side.
3. The bright sun also harms - leaflets can get sunburn.
The best option is diffused sunlight. With a lack of natural light, fluorescent lamps will help.
Yellowing of the top leaves of the flowers indicates a lack of nutrients. You can fix it by increasing the dosage of fertilizers or the frequency of feeding. But you need to do this carefully so as not to overfeed. From an excess of fertilizers, problems also arise.
Low ambient temperature. Since hibiscus comes from the tropics, it means heat-loving. The temperature in the room where the rose is kept should be between 18-300 C. Otherwise, the plant begins to drop leaves. During the rest period, the temperature should not be lower than 15 degrees.

Diseases and Pests

Chlorosis

When a Chinese rose is infected with viruses, the leaves not only turn yellow, but also become stained. One of the common viruses is chlorosis. In a plant infected with chlorosis, the leaves turn yellow, and the veins retain their natural color.

Chlorosis indicates improper soil acidity. Sometimes, in an infected plant, leaves turn yellow only where the source of the disease appears. And sometimes the leaves turn yellow and fall off, the tops of plants and underdeveloped roots die off.

You can fix it with a complex mineral fertilizer like "Uniflor-Micro", as well as a transplant to another soil. Iron chelate spraying will also help. To avoid chlorosis, it is not recommended to water the flower with hard tap water, because it oxidizes the soil.

Spider mite

Another reason for yellowing leaves is a spider mite. You can detect it only if you examine the leaves with a magnifier. Without a magnifying glass, you can see a weightless web on leaves and buds.

Insecticides that are sold in flower shops or washing the leaves with soap and water will help save the diseased plant. After bathing, the flower is sent to the shower. The soil in the pot is covered with a film.

Even with the help of insecticides, the plant recovers for a very long time.. In order to prevent the spread of the tick, it is necessary to prophylactically treat it twice a year. The treatment is carried out with Agravertiv, Fufan or Aktlik. Processed three times at intervals of four days.

A spider mite starts up where there is dry air. Therefore, in rooms where dry air must be used humidifiers or put a container of water near the flowers. Regular spraying is beneficial for hibiscus.

Attention! When using pesticides in hot weather or their overdose, lead to yellowing and falling leaves of Chinese roses. Do not use pesticides too often.

Why does hibiscus drop buds?

Chinese rose buds turn yellow and crumble for several reasons:

If during budding the pot with hibiscus is rearranged from place to place. The pot should stand in one place.
If the plant is in a poorly lit place. Move it closer to the light.
If the flower is watered with cold water. Water for irrigation should be used at room temperature and standing. You can use melt water after defrosting the freezer.
When drying the soil in a pot. It is necessary to water regularly, in the morning or evening hours, every two days.
With severe overmoistening of the substrate.
With a lack of fertilizer. During the growing season and flowering, hibiscus needs more nutrients than during dormancy. It must be fed complex fertilizer, in which the minimum amount of phosphorus. From an excess of phosphorus, the leaves turn yellow. Top dressing must be applied in cloudy weather, in well-moistened soil.
If the plant has the wrong soil. The soil should consist of two parts of turf and one part of humus, leafy soil and sand.

After finding out the cause of yellowing of the leaves of the Chinese rose, and after its elimination, the flower will quickly recover. At this time, you can trim the long shoots.

Reference! During dormancy, the flower prepares for a beautiful lush flowering. Accordingly, the conditions of detention should be optimal: the air temperature should not be lower than 150 C.

When is the process natural and when is it not?

Leaflets of old specimens preparing to die naturally turn yellow. Although in this case, you can try to revive him. This can be done by removing yellowed leaves and using pruning. And when caring for such a bush, you must follow all the rules of care
