Indoor rose or, as it is also called, tea is a rather capricious plant. Falling and yellowing of foliage can occur for several reasons. It is important to correctly determine the factors that caused this nuisance.

The nature of the yellowing of leaves at a room rose

Yellowing foliage may look different depending on the cause. Solid yellowing occurs with iron deficiency, partial with a lack of magnesium or manganese.

Rose room

In some cases, the edges of the sheet plate turn yellow first, and only then the entire sheet. With a lack of nitrogen, the spots are painted black with yellow spots.

Important! Before starting treatment of the species, you should carefully examine the rose and understand the nature of the disease or the cause of the appearance of the uncharacteristic color of the leaves.

Poor care as a cause of yellowing and falling leaves of a home rose

Why do the leaves of a Chinese rose or hibiscus disease turn yellow

Failure to comply with the main rules of care can lead to a change in the appearance of the flower. There are several reasons:

  • Non-compliance with watering standards.
  • Incorrect transplant.
  • Poor lighting.
  • Dry air.
  • Deficiency or lack of minerals in the soil.
  • Malicious insects.
  • Fungal or infectious diseases.

Well-groomed plant

More details about all this will be written below.

Unfavorable indoor climate

The plant should be exposed to light for 6-7 hours a day. For cultivation, it is recommended to use the western window. Lack of light will instantly affect the appearance of the rose. Yellowing primarily begins with the shaded side.

If the air in the building where the rose is located is too dry, it is necessary not only to spray the flower in a timely manner, but also strive to increase the humidity throughout the room. It is advisable to carry out this procedure twice a day.

For reference! A comfortable indoor air temperature in the summer should be kept in the range +20 - +22 degrees. During hibernation - +15 degrees.

Indoor rose is great for fresh air, but does not tolerate drafts. It can be placed on the loggia or near an open window.

Stagnant moisture due to excessive watering or poor drainage

The flower may lose part of the foliage due to excess moisture. If the soil of the rose is constantly wet, then this can lead first to yellowing, and then to rotting of the plant.

Yellowing leaves

You can avoid moisture stagnation with good drainage. The bottom of the pot must be equipped with drainage holes. It is important when transplanting to use new material for this and systematically water the plant.

Incorrect transplant

A room rose can get sick with an untimely transplant. It is strictly forbidden to perform this procedure immediately after purchase. The adaptation period should take place from 10 to 14 days.

Rose transplant

At home, it is recommended that the plant be placed on the southwestern side and carefully monitor its condition. The transplantation is carried out exclusively by transshipment in order to avoid damage to a weak and very delicate root system.

Important! The destruction of an earthen coma should not be allowed during the transplantation of a room rose.

At the bottom of the pot you need to lay the drainage and install a room rose. The voids are filled with special soil intended for breeding roses.

With self-preparation of the substrate, it is important not to forget about the required level of acidity - 5-6 pH. Ceramic containers are perfectly suitable for this type; they do not heat up in the sun.

Attention! After transplanting, wait at least 24 hours in the shade.

Nutrient deficiency

By external signs, you can understand why the leaves of a room rose turn yellow. With a lack of one or another microelement, the home plant begins to hurt and yellowing of leaves occurs.

  • Nitrogen. In spring, during the period of active vegetation, the rose needs nitrogen in the soil. With a lack of this element, the leaf plates turn very pale and yellow. First of all, yellowing begins with the lower leaves and gradually captures the entire plant. Nitrogen deficiency leads to leaf fall. A flower containing urea can save the flower.
  • Potassium. The substance strengthens this plant. Timely dressing of roses with potassium will help survive the winter time. With a deficiency of this trace element, buds do not form on the rose, the edges of the foliage not only turn yellow, but also completely dry. Shoots and stems turn black. The appeared leaves acquire a red tint.

External Signs of Nutrient Lack

  • Iron. Iron deficiency leads to a very dangerous disease - chlorosis. The leaves of the flower begin to fade and curl. Young leaves are the first to suffer, but due to the fact that the disease develops very quickly, yellowness passes to the whole flower. The yellow color of the leaves is not the only sign of iron deficiency. Rose stops growing and the plant sheds green mass. Most often, the reason is a low pH. To combat chlorosis, it is necessary to increase the acidity of the soil composition. It is recommended to use Fevorit or Ferrilen.
  • Manganese. A lack of manganese in the soil is a condition under which yellowing begins inside the leaf, between the veins. This happens when using the wrong soil. An excess of lime or an alkaline substrate can affect the plant. For treatment, manganese sulfate and an urgent decrease in pH are used.
  • Magnesium. With a lack of magnesium, light spots may appear on the green mass. The area between the veins is colored red. If the deficiency level is critical, then the leaves will begin to dry and fall off. The timely introduction of magnesium sulfate and wood ash into the soil will help to quickly save the situation.

Feeding too private

With an excess of nitrogen in the soil, the plant will begin to "fatten". There is a violent development of shoots and leaves. Rosa gives all her strength to maintaining greenery. Because of this, it is not able to form buds and flowers. Also, increased levels of nitrogen contribute to the development of fungus in the soil.

If you overfeed the plant with phosphorus, then it simply can not absorb the remaining necessary elements.

Important! It must be remembered that only balanced application of fertilizing will allow you to get a healthy and beautiful plant.

Untimely application of potassium or calcium to the soil will lead to inhibition of growth and wilting of the stems and shoots of the rose.

Spider mite on a room rose and yellow leaves

Why does cyclamen turn yellow when it blooms

When a spider mite appears, an instant depletion of the plant occurs. First, the leaves turn yellow, then they dry up and fall off. Due to the fact that this insect multiplies very quickly, the plant should be rescued as quickly as possible.

Spider mite

Why does a spider mite appear

Most often, the pest is brought on itself by pets or it is brought in by draft. The most exposed species are in dry and warm climates.

If the plant has been in the sun for a long time and it simply does not have enough air, then this also causes the appearance of a spider mite.

The main signs of the pest

This harmful parasite is able to affect not only the indoor rose, but also all neighboring plants. Due to its small size, it is almost impossible to notice with the naked eye. Although, upon careful examination, it is possible to detect the primary signs of its appearance:

  • Light spots on the leaves, which gradually increase.
  • Cobweb at the junction of the stem and leaf.
  • The green mass turns yellow and completely falls.

With a massive invasion, the flower is literally covered with small red dots - ticks.

What to do if a cobweb appears on a rose and the leaves turn yellow

A small amount of pests is not able to greatly harm the plant, but at elevated temperatures they can develop at lightning speed. The invasion of ticks leads to the rapid depletion of the roots.

Spider web

How to deal with a web on a room rose? There is a wide range of tools to save tea roses from insects. The feasibility of using one or another method directly depends on the level of damage to the flower.

Chemicals

Before using chemical pesticides, it is necessary to familiarize themselves with their characteristics and methods of use.

Experienced flower growers to combat spider mites recommend using:

  • Actellik. Able to protect the plant for 10-20 days. Processing should be carried out with a temporary break. It is strictly forbidden to use indoors. The drug is toxic. For processing, 1 ampoule is diluted in a liter of water. Spraying is carried out in a respirator.
  • Fitoverm. Absolutely safe tool that can kill a parasitic species in 2-3 hours. 2 treatments are required. 5 ml of the drug is diluted in 2.5 liters of water.

On a note! There is still a mass of various preparations that can save the plant from damage. Before using any product, it is very important to carefully read the instructions and act in accordance with it.

Folk remedies

A favorite remedy that can save from any insects is the infusion of garlic. To do this, 500 g of spice is mixed with 3 liters of water. It is necessary to insist it at a temperature of + 20 ... +25 degrees for 5-7 days. For processing, the concentrate must be diluted: 20 ml of tinctures are diluted with 3 liters of water. They can spray not only the rose, but also the earth around.

Using a soap solution, you can process all the shoots and leaves. To do this, laundry soap should be grated and diluted in warm water.

Garlic tincture

Also, the use of alcohol or vodka to wipe the leaves helps not only to protect against ticks, but also is an excellent disinfectant procedure.

Other pests that cause yellowing and leaf fall

Why do geraniums turn yellow leaves at home - causes and treatment

There are other pests that contribute to the fact that the leaves turn yellow in this species:

  • Common thrips. The appearance of this insect occurs when the temperature regime in the room is not observed. With an increase in temperature and a lowered level of humidity, a silver coating appears on the leaves, due to which the flower will look yellowed. In order to get rid of it, it is necessary to urgently treat the entire pot and everything around with an insecticidal agent. It is better to do this with a finely divided spray gun.
  • A hot climate also contributes to the emergence of cicadas. The rose subspecies of this pest most often lives on a room rose. If white spots appear on the leaves, it is urgent to make a soap solution and treat it with a flower. When the foliage began to fall off, it is possible to save the rose only with the help of insecticides.
  • Many insects are capable of eating the root system of a room rose. If the roots are damaged, they begin to dry out, and eventually all leaves may fall. All new leaflets are deformed. The flower is able to completely wither, if you do not systematically process the rose. Fitosporin is perfect for these purposes. Spraying and watering should be carried out 2 times a month.

On a note! Falling leaves can be caused by the natural diligence of the rose. If the flower discards the lower leaves, then it is possible to worry and not worth it. But if the fall is massive, it is urgent to start treatment.

Viral and fungal diseases, due to which mini-roses turn yellow and fade

Most often, the plant is damaged by the following diseases:

  • White plaque on the leaves appears due to powdery mildew. If tightened with treatment, shoots and even buds may suffer. Most often, infection occurs due to a lack of air and abnormal feeding. To save the flower, all damaged areas should be removed and treated with any fungicide.
  • When overflowing, brown or red spots may appear on the plant, which occur when the rose is infected with rust. She is able to literally scorch sheet plates, which subsequently fall off. As with other infections, fungicidal drugs are great.
  • The defeat of black spotting is manifested by yellowing of the foliage and the appearance of dark gray spots on it. A rose can be saved if treated with folk remedies or chemicals. For example, the use of a solution of manganese will perfectly protect the flower at the initial stage of infection.

If the flower was damaged by the virus, then it is not possible to save it. You should get rid of it and treat everything around with any disinfectant.

Advice! Before proceeding with the treatment of a particular disease, it is necessary to clearly determine the nature of its appearance.

Yellow leaf preventative measures

For a healthy plant, it is extremely important to follow the rules of prevention. They consist in the following conditions:

  • watering is carried out only at room temperature;
  • protection of roses from drafts;
  • compliance with optimal soil moisture;
  • taking out a flower in the summer to the balcony;
  • regular and proper feeding;
  • correctly performed transplant;
  • preventive treatment of indoor roses with pest protection.
