Why do the leaves of a room rose turn yellow and a cobweb appears

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

The nature of yellowing of the leaves of a room rose

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

Room rose

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

Poor grooming as a cause of yellowing and leaf fall in a home rose

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

• Failure to comply with watering norms.
• Incorrectly performed transplant.
• Poor lighting.
• Dry air.
• Deficiency or lack of minerals in the soil.
• Harmful insects.
• Fungal or infectious diseases.

Well-groomed plant

More details about all this will be written below.

Unfavorable indoor climatic conditions

The plant should be exposed to light for 6-7 hours a day. It is recommended to use a western window for cultivation. 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, then it is necessary not only to spray the flower in a timely manner, but also to strive to increase the humidity in the entire room. It is advisable to carry out this procedure twice a day.

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

Stagnant moisture due to over-watering or poor drainage

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

Yellowing of leaves

You can avoid stagnant moisture 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

Indoor rose can get sick with an untimely transplant. It is strictly forbidden to perform this procedure immediately after purchase. The adaptation period should be 10 to 14 days.

Rose transplant

At home, it is recommended to place the plant on the southwest side and carefully observe its condition. The transplant is carried out exclusively in a transhipment way to avoid damage to the weak and very delicate root system.

Drainage must be laid at the bottom of the pot and a room rose must be installed. The voids are filled with special soil for growing roses.

When preparing the substrate yourself, it is important not to forget about the required acidity level - 5-6 pH. Ceramic containers are perfect for this type, they do not heat up in the sun.

Nutrient Deficiency

By external signs, you can understand why the leaves of a room rose turn yellow. With a lack of one or another trace element, the houseplant begins to ache and the leaves turn yellow.

• Nitrogen. In spring, during the active growing season, 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 from the lower leaves and gradually captures the entire plant. Nitrogen deficiency leads to foliage loss. A product containing urea can save a flower.
• Potassium. The substance helps to strengthen this plant. Timely feeding the rose with potassium will help to survive the winter time. With a deficiency of this microelement, buds do not form on the rose, the edges of the foliage not only turn yellow, but also dry out completely. Shoots and stems turn black. The leaves that appear acquire a red tint.

Outward signs of nutritional deficiencies

• Iron. Iron deficiency leads to a very dangerous disease - chlorosis. The leaves of the flower begin to wither and curl. Young leaves are the first to suffer, but due to the fact that the disease develops very quickly, the yellowness spreads to the entire flower. The yellow color of the leaves is not the only sign of iron deficiency. The rose stops growing and the plant sheds its green mass. The most common cause is low pH. To combat chlorosis, it is necessary to increase the acidity of the soil composition. It is recommended to use Fevorit or Ferrilene.
• Manganese. 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 attack the plant. For treatment, manganese sulfate and an urgent lowering of the pH level are used.
• Magnesium. If there is a lack of magnesium, light spots may appear on the green mass. The area between the veins is colored red. If the level of deficiency is critical, then the leaves will begin to dry and fall off. Timely application of magnesium sulfate and wood ash to the soil will help to quickly save the situation.

Too frequent feeding

With an excess of nitrogen in the soil, the plant will begin to "fatten". There is a violent development of shoots and leaves. The rose gives all its strength to maintain the greenery. Because of this, it is unable to form buds and flowers. Also, the increased nitrogen level promotes the development of fungus in the soil.

If you overfeed the plant with phosphorus, then it simply will not be able to assimilate the rest of the necessary elements.

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

Spider mite on a room rose and yellow leaves

When a spider mite appears, the plant is instantly depleted. At 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 saved as quickly as possible.

Spider mite

Why does spider mite appear

Most often, the pest is brought on by pets or it is brought in by a draft. The most attacked 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 is also the reason for the appearance of a spider mite.

The main signs of the appearance of a pest

This harmful parasite is capable of infecting not only indoor roses, but also all neighboring plants. Due to its small size, it is almost impossible to notice with the naked eye. Although, upon close 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 falls off completely.

During a mass 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 number of pests are not capable of much harm to the plant, but at elevated temperatures they can develop with lightning speed. Invasion of mites leads to a rapid depletion of the roots.

Spider web on a rose

How to deal with cobwebs on a room rose? There is a wide range of insect repellents available for the tea rose. The feasibility of using this or that method directly depends on the level of damage to the flower.

Chemicals

Before using chemical pesticides, you should be familiar with their characteristics and methods of application.

Experienced florists recommend using:

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

Folk remedies

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

With the help of a soap solution, you can process all shoots and leaves. To do this, you need to grate the laundry soap and dilute it in warm water.

Garlic tincture

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

Other pests that cause yellowing and foliage

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

• Common thrips. The appearance of this insect occurs when the temperature regime in the room is not observed. When the temperature rises and the humidity level is low, a silvery bloom appears on the leaves, which will make the flower look yellow. In order to get rid of it, it is urgent to treat the entire pot and everything around with an insecticidal agent. It is better to do this with a finely dispersed spray bottle.
• The hot climate is also conducive to the emergence of cicadas. A rosy subspecies of this pest most often lives on a room rose. If white spots appear on the leaves, then it is urgent to make a soapy solution and treat the flower with it.When the foliage began to fall off, the only way to save the rose is 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 over time, all the leaves may fall off. All new leaves are deformed. The flower is capable of completely withering, if you do not carry out systemic processing of the rose. Fitosporin is perfect for these purposes. Spraying and watering should be carried out 2 times a month.

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

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

• White bloom on the leaves appears due to powdery mildew. If you delay with treatment, shoots and even buds may suffer. Most often, infection occurs due to lack of air and irregular feeding. To save the flower, all damaged areas should be removed and treated with any fungicide.
• With overflows, brown or red spots may appear on the plant, which occur when the rose is infected with rust. She is able to literally scorch leaf plates, which will subsequently fall off. As with other infections, fungicidal preparations are excellent.
• The defeat of black spot 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 manganese solution will perfectly protect the flower at the initial stage of infection.

If the flower has suffered from a virus, then it is not possible to save it. You should get rid of it and treat everything around with any disinfectant.

Preventive measures to prevent yellow leaves

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

• watering is carried out only with water at room temperature;
• protection of the rose from drafts;
• compliance with the optimum soil moisture;
• taking out a flower to the balcony in the summer;
• regular and correct feeding;
• correctly performed transplant;
• preventive treatment of a room rose with pest control agents.

Indoor rose in the interior

It must be understood that adherence to preventive measures will help avoid diseases in the future.

Before purchasing a room rose, you need to carefully study the rules for caring for the plant. After all, compliance with elementary standards will allow you to get a wonderful decoration for any home. But improper care will not only lead to a painful appearance of the plant, but also to its possible death.
