Why do the leaves of a rose turn yellow?
The most common reasons why the leaves of a rose turn yellow are several.
Deficiency of mineral elements
Due to the lack of various components, the rose can turn yellow in different ways. If the plant lacks nitrogenous elements, then the bush will turn yellow completely, and this will start from the lower rows of foliage. In the fight against this process, universal complex mineral fertilizers for decorative flowering crops, or a solution on urea, can help. If the plant has a lack of iron, then yellowness will form in specks, and this will happen from the top and crawl to the bottom. To combat this process, any acidifying fertilizers and feeding will be used.
Excess fertilization and fertilization
An overabundance of mineral components can also adversely affect the development of the plant, as well as force the plant to shed its foliage. If the culture becomes weak and you want to feed it, but the initial concentration should be reduced by fifty percent. Otherwise, there is a threat to burn the root system.
Rose leaves turn yellow from diseases and insect pests
The most common disease is called chlorosis. You can fight it with a drug called antichlorosin. It dissolves well in the water mass. You need to use it a couple of times, during the active growing season. It will need to be repeated in ten to fifteen days, if necessary.

Excess moisture
Roses love abundant watering, but its excessive presence can adversely affect the plant. The plant may not only begin to turn yellow, but the root system may also begin to rot. In watering mode, you need to find a moderate dose of moisture. To do this, you need to provide a good drainage layer, as well as watering, only when the top soil layer begins to dry out. Also, spray with warm, clean, settled water.
Rose leaves turn yellow from transplant
The plant may start to turn yellow due to improper transplantation. This procedure needs to be done only once a year, preferably in the last month of the winter period. The diameter of the new pot should be chosen two to three centimeters larger than the diameter of the old container. You need to use the transshipment method, that is, transplant with your own earthen clod in order to minimize the risk of damage to the root system. The pot should be placed in a warm place, without cold drafts and strong wind currents.
Rose leaves turn yellow from lack of nutrients
If the plant is not sick with anything and is not affected by insect pests, then most likely it simply does not have enough micronutrients, macronutrients and nutrients. By the appearance of the foliage, you can understand which elements the culture lacks. Feeding must be done with a suitable composition of the product. The most important period of top dressing is the beginning and flow of flowering. If the plant is not fed, the buds will be smaller in size and frequency. And the foliage, in turn, will turn yellow, dry out and fall off.
Non-compliance with the watering regime
With an incorrectly designed watering regime, the life of the plant can be very ruined. Keep your watering liquid warm at all times. Cold water can lead to the fact that the bush gets sick, slows down in its development and will soon die. The water must be warm, clean, settled and soft. Some flower lovers even recommend boiling to reduce any risks.
The irrigation regime must be made based on the state of the soil. If the topsoil begins to crack, it means that watering the crop is simply necessary. Adult specimens should be watered about two to three times every seven days. During the heat of summer, you need to slightly increase the volume and frequency of watering. And also place a device for humidifying the air in the room with the plant.
For what reasons do the leaves of a rose still turn yellow?
There are several more factors due to which the rose may begin to turn yellow: 1) Too high level of ambient temperature; 2) Lack of lighting; 3) An excess of direct sunlight. Because of this, yellowish or brown spots may appear. They can also appear due to spraying with cold water in the bright sun. In this case, you need to change the habitat of the plant; 4) Cold drafts and strong winds. Because of them, the culture can freeze and naturally weaken. In this case, you need to create a protective layer.
Diseases and insect pests

Probable disease
A rose can get sick with powdery mildew. This disease manifests itself as a loss of color intensity, as well as shedding foliage. If the climate for a rose is not favorable, then various fungal infections can also affect the rose.
Insect pests
Although thorns are present on the rose, it is not poisonous. That is why insect pests love to feed on it. For example, a spider mite - in the fight against this pest, preventive measures are very important. If the foliage begins to fade and lose its color, then this may signal that the larvae of this pest live in the root system. Unfortunately, its reproduction occurs very quickly, which is very dangerous for the plant, because the colony can easily destroy the culture. For the fight, it is recommended to purchase insecticidal preparations and carry out treatment. If a one-time event did not help, then it must be repeated.
Himself a spider mite, very small in size. It lives on the bottom of the leaf. With his presence on the leaves, small light specks appear - these are bite marks through which he uses the nutritious juice of the plant. Further, a very small cobweb will appear in its habitats.
