Why do Chinese roses fall off their leaves and bloom buds fall off, and what if the plant drops them?

The Chinese rose (hibiscus) has won the hearts of many gardeners with its beauty. Bright colors and lush flowering are complemented by another important quality - unpretentiousness in cultivation.

Chinese rose is one of the many species of hibiscus. In total there are about 250 pcs. The birthplace of the Chinese rose is Southeast Asia.

From the article you will learn why leaves and unblown buds fall off from hibiscus, and also read what to do if the plant drops them.

What is leaf fall?

Leaves that are chlorophyll-free usually fall.. They are withered or completely dried. It should be borne in mind that falling can be both natural and caused by any negative factors. Not only leaves, but also buds can fall from plants.

Appearance

Very often, the leaves of a Chinese rose begin to turn yellow. Appearance becomes not aesthetic, the plant looks unhealthy. And after that a real leaf fall can even begin. In some cases, all leaves fall.

Why is this happening?

There can be many reasons why hibiscus leaves have fallen. Consider the most common of them.

Natural causes. The leaves of a Chinese rose may turn yellow and fall for no apparent reason. If the flower is kept in favorable conditions and provided with proper care, do not panic if a couple of leaves turn yellow and opal on it. It is natural. So the plant gets rid of old leaves.
Lighting. The Chinese rose grows well both in good light and in shaded conditions. However, it is worth knowing that it does not tolerate sudden changes in the lighting mode. Moving a plant to the street, or, conversely, from the street to the room, can cause him stress. The consequences of a stressful condition are yellowing and loss of foliage.
Wrong watering. An excess of moisture in the soil, as well as its lack, adversely affects the condition of the rose. It is necessary to keep the soil moist, but not to allow excess. Stagnation of water leads to decay of the root system, and, in turn, to falling leaves. Lack of moisture can also cause leaf falling.
A Chinese rose, which is more than 4 years old, needs daily watering. Younger plants need less water.
Temperature violation. Chinese rose loves warmth. The optimum temperature for it is from +20 to 30 degrees. Going beyond this range, as well as sudden temperature changes can provoke yellowing and falling of leaves. It is necessary to protect the rose from cold drafts.
Incorrect feeding. An excess of some and a lack of other substances can adversely affect hibiscus. So, magnesium and potassium are the necessary elements for it, which should be contained in large quantities. But an excess of nitrogen and phosphorus can cause yellowing of the leaves.
Diseases. The most common disease for a Chinese rose is chlorosis. The reason for its appearance, as a rule, is hard water, as well as alkaline soil and iron deficiency. Chlorosis can cause a flower to die in a short time.
Pests. The spider mite is the pest that most often infects the Chinese rose. It leads to yellowing and wilting of leaves, which subsequently fall profusely.

Unblown flowers

If a Chinese rose loses unbroken buds, there is most likely a violation in its content.

The most common cause of bud dropping is the drying out of the soil. However, there may be others. In principle, they do not differ from the above reasons for falling leaves:

problems with lighting;
improper watering;
adverse temperature conditions;
lack or excess of fertilizers;
diseases and pests.

IMPORTANTA: For a Chinese rose, you need the "right" pot. It should be of optimal size and with a good drainage system.

When to worry

Hibiscus leaves are not always a cause for concern. If one or a couple of leaves turn yellow and fall, do not worry. Any plant is characterized by these “renewal” processes when old leaves fall and new ones appear.

However, if the leaves quickly began to turn yellow and fall, it is worth the alarm. First of all, you need to find the cause of the negative impact and eliminate it. In the initial stages, you can always revive the plant.

If partial falling of leaves can be attributed to natural causes that do not require action, then falling of unopened buds is an immediate signal to action to find and eliminate negative factors.

Effects

Massive and transient falling of leaves and buds can lead to the death of the whole plant. It must be remembered that almost any cause of subsidence in the early stages can be eliminated without consequences. And if delay is allowed, you can lose the plant.

What to do if hibiscus sheds vegetative organs?

If the rose was recently transferred from a darker room to the light, then perhaps it received stress. It is necessary to gradually accustom the plant to light, protecting it from sunlight. If the rose was moved from a place with good lighting to a darker one - it costs her the first time to arrange highlighting.
Review the watering regime. It is necessary to water the Chinese rose as necessary, not allowing the soil to completely dry out. If stagnation of water is observed, most likely for this reason root decay has begun. In this case, you need to carefully remove the plant from the pot and rinse the roots. Rotten and blackened should be cut off, sprinkling the places of slices "Kornevin." Having planted a rose in a new substrate, it is recommended to treat its crown with Epina solution.ATTENTION: Insufficient watering can be judged by dry soil. This condition should not be allowed.
If the room temperature is below +18 or above +30 degrees, urgent need to take measures. If the room is cool, you can turn on the heater. In hot conditions, it is necessary to humidify the air and spray the leaves with water.
Review the composition of fertilizers. Chinese rose is important magnesium and potassium. An excess of nitrogen and phosphorus fertilizers is harmful. In floriculture, there is even such a thing as a “nitrogen burn”, in which the leaves turn yellow and fall off.
Inspect the flower for damage by disease and pests. Most often, the Chinese rose is chlorosis. In this case, first of all the leaves die, and then the shoots and the whole plant. It is important to transplant the rose into a new soil and make fertilizer with iron content.
Often a Chinese rose is hit by a spider mite. It can be detected by the presence of small black dots and cobwebs. It is recommended to treat the plant with a soapy solution. With its inefficiency, it is worth resorting to chemical processing, for example, Aktara, Aktellik or Fitoverm.

Buds

In cases when unopened buds fall, the above instructions should be followed, since the reasons for falling leaves and buds are usually the same. However, it is important to pay attention to the pot that contains the Chinese rose. A tight pot can cause weak buds to form..

It is best to change the pots as the plant grows and develops, or you can immediately plant the hibiscus in a larger pot. It must have a good drainage system.

Prevention

In order to prevent the receding of leaves and buds, favorable conditions and proper care for the Chinese rose should be provided.

Aftercare

Leaving after plant restoration is no different from caring for a normal healthy plant. It consists in providing optimal lighting, temperature conditions, organizing proper watering, fertilizing and protecting the plant from diseases and pests.

By following the basic recommendations for caring for a Chinese rose, you can eliminate the causes of falling leaves and buds, preventing their reappearance. Indoor beauty will delight the eye with its rich green leaves and bright, large flowers of red, yellow, pink and lilac color for a long time.
