Why does a rose have leaves falling and what to do

Recently I have been growing roses. But lately I have been observing that the leaves began to actively crumble from the plants. Why is this happening? (Konstantin)

Rose is a beautiful flower that will decorate both the apartment and the garden. But with fallen leaves, she is no longer so beautiful.

The reasons why a flower sheds leaves may be as follows:

  • physiological aging. Each flower has its own lifespan. Therefore, upon reaching the final stage of its development, the process of throwing off the obsolete leaf plates and buds begins;
  • seasonality. At the end of the vegetative period after flowering, such a picture is observed quite often. This occurs with the aim of renewing the plant organism and its transition to the dormant stage. Subsidence usually occurs in the fall;
  • improper care. The yellowing of the leaves and their further dropping can signal that the flower is being watered or fed incorrectly. Also, an excess of sunny color or a draft can fall on it;
  • improperly selected soil. A rose in an inappropriate soil begins to wither and wither;
  • parasite attack. Insect pests with abundant settlement can destroy a beauty in a matter of days. Their presence is evidenced by the cobweb, through holes in the leaves / buds, etc.;
  • damage to the flower by pathogenic microflora. In this case, additional symptoms will indicate infection: the appearance of spots, a putrid odor, etc.

As you can see, at first glance it is quite difficult to understand why the leaves of a rose fall.

The situation can be corrected only by finding out the cause and eliminating it. In some cases, additional pet treatment may be required. If this is not done, then the garden beauty may simply die.

The reasons

The Chinese rose is undemanding, it will suffer shortcomings in caring for it, if inattention to the plant does not develop into a constant phenomenon. More often, for objective reasons, the leaves turn yellow and fall off the rose. It is important to understand what is happening and take action to eliminate weaknesses in the care, so as not to let the flower die.

Consider the most common causes of yellowness and leaf fall.


In the Chinese rose, in preparation for the dormant period, the leaves turn yellow and fall. The flower sheds part of the leaves in winter, it needs rest after flowering and to recuperate for the future. A rose gets rid of yellowed old ones when many young leaves appear on the bush.

Old plants that are about to die are also throwing off their leaves. These are natural causes of leaf wilting.


Hibiscus doesn't like being moved from place to place. A simple turn or transfer to another room causes a lot of stress on the plant. The flower sheds yellowed leaves before adapting to new conditions. A difficult test for a rose is transplanting into a new pot. She is sick for a long time, because the roots are often damaged during transshipment. While new roots are recovering and growing, the flower sheds its foliage.

Influence of moisture

Dried soil in a pot of Chinese rose leads to root death and massive foliage flying. The reason is a cramped pot or insufficient moisture. The required amount of nutrition is not delivered to the leaves, they turn yellow and fall off. Find out the exact cause by the dried earth in the center of the flower pot. To do this, the rose is watered in the morning, and closer to night they look to see if the earth in the center of the container has dried up. Dryness suggests that the flower is cramped in this container. In summer, the Chinese rose feels a lack of moisture even with constant watering in the morning and evening.

Excess moisture can adversely affect the flower. The hibiscus withers. The soil in the pot is compacted, air does not enter there. Stagnant water appears, the soil becomes waterlogged, which leads to the emergence of bacteria and fungi. This is due to the large pot. Plant roots rot and die in this environment. Diseased roots do not supply enough nutrition for the normal existence of the hibiscus. The leaves turn yellow and fall off.

Temperature regime

As a native of the tropics, the Chinese rose cannot stand cold and drafts and is kept away from air conditioners. When airing, the rose is closed from the air stream. An indoor flower is kept in an acceptable temperature environment of + 18.30 ° C. In winter, when the rose is dormant, the room temperature is maintained at + 13.15 ° C, provided that there is additional lighting. In the spring and until the beginning of autumn, the room is maintained at + 17.23 ° С. Cooling to + 10 ° C provokes yellowing and leaf fall.


Another reason that the leaves of the Chinese rose turn yellow and fall off is improper lighting. As usual, they turn yellow on the side of the plant that is in the shade. However, hibiscus should not be exposed to direct sunlight. Excess sun will cause burns, which will cause the leaves to turn yellow and they will fall off.

Hibiscus still reacts to lack of light. Diffused lighting has a beneficial effect on the flower. And in winter, the lack of natural light is complemented by the light of fluorescent lamps.


Evidence of chlorosis in Chinese hibiscus is yellowing of the leaf plate, while the veins remain green. In addition, spots appear on the leaves. The reason for these phenomena is called the increased acidity of the soil, which is provoked by tap water. Chlorosis does not affect the entire plant at once. More often young roots and tops of a rose are ill, and yellow leaves fall off.

Lack of minerals

It is important to notice in which part of the Chinese hibiscus the leaves turn yellow. A lack of nutrients is said if the upper leaves of the flower turn yellow. Leaves turn yellow when the content of zinc, manganese, magnesium and iron is insufficient. The increased content of chlorine and calcium in the water causes shedding of the lower leaves, and new ones grow yellow. If there is not enough nitrogen or iron, the phenomenon is repeated.

Fertilizers must be applied carefully, the main thing is not to go over the norm. If there is not enough nitrogen, the veins of the leaf turn yellow, if potassium, the whole plate turns yellow. The increased content of magnesium and potassium does not harm the development of hibiscus.

The content of nitrogen and phosphorus exceeding the norm leads to massive yellowing of the leaves.

Spider mite

The pest activates on the plant when the air is dry in the room. In addition to yellowing of the leaves, cobwebs and whitish bloom form on the flower. Traces of ticks are traced on the back of the leaves in the form of small dots. In order not to provoke the activation of mites, the air next to the plant is moistened, and vessels with water are placed next to it.

Lack of lighting or moisture

The rose loves well-lit places, and when planting a bush in a dark corner of the site, it will lack sunlight not only for normal development, but also for flowering. Therefore, the plant begins to shed its leaves and buds.

At the same time, it is not recommended to plant roses in an area that is under the sun all day, as this will lead to a similar problem. It is better to give preference to a flower bed that is well lit in the morning - this way there will be enough light, and the leaves with buds will not burn in the scorching midday sun.

Drying of buds and leaves can be the first sign of a lack of moisture, especially if you skip the next watering in hot summer. Conversely, if there are signs of rot on the shoots, the cause is rotting of the root system as a result of waterlogging and stagnant moisture.

It is important to choose the right place for planting the rose and water it regularly so that the flower has enough strength to grow leaves and bloom.

Preventive measures

There are several preventive measures that will help prevent premature drying of roses:

  • water properly. For irrigation, you need to use settled and warm water. In winter, it will have to be warmed up to room temperature.
  • preventive spraying. At least twice a season, flowers must be treated with fungicidal and insecticidal agents.
  • regular feeding. So that the tips of the leaves and leaf plates do not turn yellow, you need to add mineral and organic fertilizers to the soil 2-3 times a month.

Only prevention can help grow beautiful flowers

Drying of leaves is a fairly common problem that some growers face when growing roses. Therefore, every person who is going to plant such flowers should figure out why they dry, as well as familiarize themselves with preventive measures to prevent the problem.

Hibiscus pests

Not only violations of the rules of care and illness lead to the fall of the foliage of the plant. Another serious problem is the appearance of pests. If treatment is not started on time, hibiscus will not only grow poorly, but may also wither completely.

Aphids on hibiscus - how to process

One of the most common pests is aphids. Before you find out why the leaves of hibiscus turn yellow, you need to carefully examine it. It is possible that these little green bugs are sucking all the juices from the hibiscus. Aphids can be seen on leaves and buds. It does not exist on the branches.

The reasons for the appearance of aphids in the house:

  • The insect can enter through open windows in summer.
  • On a person's clothes.
  • On pet hair.
  • Through other plants, which are taken out into the street or on the balcony in the summer, and transferred back to the house in the fall.

What to do if aphids appear on hibiscus:

  • The use of biologics Fitoverm and Vertimek is recommended. The bushes are sprayed with these preparations as aphids appear. An interval of 7-10 days must be maintained between treatments.
  • From fungicides with yellow foliage, Bison, Aktara, Insektor are used.
  • The safest remedy is to put fragrant pelargonium next to it, if there is such a plant in the house. Aphids cannot stand the smell of this flower. The disadvantage of this method is that for some varieties of aphids, pelargonium is a fodder plant.
  • From folk methods, you can try soapy water treatment. Dissolve 70 g of laundry soap in 200 ml. Then you need to wipe all the leaves and branches. For greater effect, the bush is then sprayed with the same solution.
  • Infusion of tobacco also repels the pest. To prepare it, you need to take 100 grams of dried tobacco. Pour 1 liter of water and put on low heat. After boiling, cook for 30 minutes. When the broth is ready to strain it, cool it, and then you can use it for spraying.
  • Infusion of marigolds. Dried inflorescences are used to prepare the infusion. Pour 100 grams of flowers into 1 liter of water. Put on fire, bring to a boil and boil for another 30 minutes. Then strain the infusion, cool, and only after that you can start using it.

Attention! An unusual way to combat aphids is with yellow-orange glue traps.

Scabbard on hibiscus

Another dangerous pest, due to which the leaves begin to wither, is the scale insect. The insect's danger lies in the fact that adults and larvae feed on plant sap. Females stick tightly to the leaf surface to protect larvae and eggs. Yellow or brown spots appear in these places. Gradually, all the leaves can fall off if the pest is not removed. Later, the infected plant also sheds buds.

Note! Getting rid of insects is difficult due to their durable shield that protects insects from chemicals.

Determining the appearance of scale insects is quite simple. Small brown bumps appear on the leaves. Most often they are located along the veins.

What to do if leaves begin to fall off because of the scabbard:

  • You need to remove the infected hibiscus to another room where there will be no plants. Then you can start treatment.
  • You can collect insects by hand. To do this, you need to make a soapy solution and wipe each leaf on both sides and all the stems.
  • After mechanical cleaning, you can start treating with insecticides Bankol, Inta-Vir, Aktellik, Mospilan. Insecticides are used according to the instructions on the package.
  • Additionally, you can spray the hibiscus with alcohol.

If a cobweb has appeared on the foliage, then a spider mite has wound up on the hibiscus. Insecticides do not help against ticks. In this case, the hibiscus must be sprayed with acaricidal preparations.

Black aphid on hibiscus

Leaves can turn yellow due to black aphids. Unlike green aphids, this species is much more difficult to breed.

Why do the leaves of a Chinese rose turn yellow and fall, what to do:

  • In the process of vital activity, aphids suck juices from leaves and stems.
  • Often ants appear along with aphids, due to which the foliage can begin to turn yellow and fall off.
  • To destroy the insect, you can use the chemicals Aktara, Fitosporin-M, Insektor, Fitoverm.
  • Folk remedies are also effective.

The foliage is sprayed with soapy water, onion peel decoction or garlic infusion. The number of treatments depends on how badly the plant is affected by the pests. Before processing, it is worth rinsing the Chinese rose under a warm shower.

Hibiscus is a very capricious houseplant native to the subtropics. So that it grows healthy, does not get sick and blooms profusely, you need to provide the indoor flower with all the conditions necessary for this. If the leaves of a Chinese rose began to turn yellow and fall off, it means that an urgent need to look for the cause and eliminate it so that the flower does not die.

Hibiscus recovery

If the reasons why the leaves of indoor hibiscus turn yellow and fall off are determined, it is necessary:

    Transplant the plant with a complete soil replacement. If the pot was very large, it is advisable to replace the container with a smaller one.

Cut off elongated shoots. This will help form a lush bush. Pruning is especially relevant for those plants that have almost completely shed their leaves.

  • Drizzle with soft water without adding nutrients. The first fertilization is carried out 2 months after transplanting.
  • Place the pot in diffused light.
  • During flowering, hibiscus impresses with its bright colors, and at rest - with fresh greenery. With proper care and a little care, a plant can enjoy living beauty for many years.
