There can be several reasons why clematis turns yellow and dry. It is important to install them as soon as possible in order to eliminate the problem and quickly revive the plant. So, for example, dangerous fungal and viral diseases that cause yellowing of leaves can lead not only to the death of clematis itself, but also to the infection of neighboring plants.

Clematis dries and turns yellow: how to quickly revive and save the plant

Why clematis turn yellow and dry leaves

Many factors can cause clematis leaves to dry out and turn yellow. These include the presence of various diseases, pest damage, improper planting and care of plants. In order for the treatment to be effective, first of all you need to find out the reason why the clematis turns yellow.

Improper fit and maintenance

Improper care, especially failure to follow watering recommendations, can cause clematis to turn yellow. With a lack of water, the leaves do not receive enough nutrients and wither, and with its excess, the root system suffers, the shoots become weak and susceptible to various diseases.

Important! Irrigation rate for clematis – from 10 to 40 liters of water per 1 bush, the exact volume is determined depending on the age and size of the plant. The recommended frequency of watering is 1 time per week, during periods of drought – 2-3 times per week.

Proper planting of clematis is equally important. Climbing plants should not be placed in areas with high groundwater levels: this can cause root rot and yellowing of leaves.

The optimal time for planting seedlings in the ground is spring or autumn; when planting, it is recommended to avoid open windy areas and shady places. The soil should not be too heavy or acidic.

Nutrient deficiency

Sometimes clematis turn yellow due to nutrient deficiencies. Top dressing is an integral part of plant care. Clematis need a whole complex of mineral fertilizers, consisting of:

  • nitrogen;
  • gland;
  • the copper;
  • zinc;
  • manganese;
  • magnesium;
  • sulfur.

Plants use zinc in the process of photosynthesis: this is why, in the absence of this substance, clematis turns yellow. To prevent this from happening, the bush is supplied with zinc sulfate. With a lack of nitrogen, the foliage acquires a reddish-yellow tint; humus, manure or peat are usually used to replenish it.

Iron deficiency causes the development of chlorosis, in which the vine turns yellow from top to bottom. To correct the situation, an iron chelate is usually added. At the same time, all clematis leaves turn yellow with manganese deficiency, which is replenished by the introduction of manganese sulfate (potassium permanganate). Due to an excess of organic fertilizers, a shortage of copper may occur, in which copper sulfate is introduced into the soil.

If gradually growing small yellow spots begin to appear on the leaf blades, and the tips of the clematis leaves dry up and curl, they lack magnesium. You can save the plant with the help of adding the sulfate of the same name.

The appearance of yellow spots only on the edges of the plates of young leaves indicates a lack of sulfur. In this case, the vine is fertilized with calcium or ammonium sulfate.

pest attack

The reason clematis turns yellow may be due to pest damage. The most dangerous for the vine are:

  • slugs and snails eating leaves in the spring;
  • beet aphid, living on the underside of leaves and sucking juice;
  • various types of caterpillars that damage the ground parts of the plant;
  • nematodes that damage the underground and aerial parts.

Large pests are harvested by hand. In addition, clematis must be treated with specialized insecticides, such as, for example, Agrovertin. You can also use folk remedies, the most effective of which are:

  • soapy solution;
  • garlic infusion;
  • ash.

fungal diseases

Another reason clematis leaves dry and turn yellow is often due to fungal microorganisms that cause wilt, leaf spots, rust and necrosis. Despite all the variety of fungal diseases, the result is the same, with full compliance with the requirements of care, clematis turns yellow and withers.

Introduction (wilting)

Wilting is manifested by the wilting of young shoots, leaves and flowers. Under favorable conditions, such as high humidity, pathogenic fungi of the genus Phomopsis living in the soil penetrate the stems. Fungal spores develop in shoots, thereby impairing the permeability of conductive tissues, which disrupts metabolic processes, causes moisture and nutrient deficiency, and clematis turns yellow.

First, the disease affects the roots, then it moves to the aerial parts. If you look closely, you can find small black spots on the clematis, which are the fruiting bodies of the fungus. The causative agent of wilt can also be a fungus such as Fusarium, which also penetrates the roots and spreads throughout the plant through conductive tissues.

Important! To prevent the development of infections and infections of other plants, diseased shoots are cut at the base and burned. After that, the soil and surviving shoots (if any) are treated with special means, such as fundazol, potassium permanganate, copper sulfate with soapy water.

Wilt is considered the most dangerous fungal disease for clematis. It begins to appear during the flowering of the vine. It is almost impossible to save a sick plant, since the focus of infection is in the lower internode, located directly above the ground or inside.

Rust

The appearance of orange-yellow spots on the leaves of clematis in early spring indicates that the flower is affected by rust. Clematis does not immediately die of rust: the damaged foliage gradually dries up and turns yellow, the new one grows, but soon repeats the sad fate of its predecessors.

If the disease was noticed in time, there is a high probability of saving the vine. To prevent the clematis from drying out, when the first spots appear, all affected parts are removed and the clematis is treated with a 2% solution of Bordeaux liquid or oxychome.

If the disease has spread and was discovered too late to save clematis, then its shoots should be cut off at the root. This will lead to a lack of flowering next year, but it will save the plant. Then you need to eliminate the weeds growing nearby, as they can also be infected. All collected coins are burned.

leaf spots

If the process of leaf wilting begins with the formation of small spots that spread throughout the plant in a short time and the clematis turns yellow, fungal organisms are to blame. There are several species of fungal diseases characterized by the appearance of spots on the leaves:

  • septoria – spots of grayish tint, have a red border;
  • cylindrosporium – ocher staining of the spots;
  • ascochites – dark brown spots.

These diseases are treated with drugs with a high copper content. It is important to remove the affected parts in time to prevent the spread of fungal spores to healthy shoots. In spring and autumn, a preventive treatment with copper sulphate is obligatory.

Necrosis

A disease such as necrosis is caused by a fungus of the genus Alternaria, which is a harmless saprotroph and usually feeds on old and dying parts of the plant. But sometimes, in a favorable environment, this fungus is activated, and then the clematis begins to dry out prematurely and turn yellow.

When the first signs appear, diseased shoots are removed, not forgetting to burn. The liana is treated with copper sulphate.

viral disease

Among viral diseases, clematis can be threatened by the yellow mosaic virus, with the defeat of which the leaves begin to discolor and turn yellow, losing the green pigment in them, which is responsible for the processes of photosynthesis. As a result, organic nutrition processes are disrupted and the plant dies. Carriers of yellow mosaic virus are insects such as aphids, mites and caterpillars.

Curing clematis infected with yellow mosaic will not work. As a preventive measure, they are treated with insecticides from sucking insects that spread the virus.

The most effective way:

  • potassium soap;
  • colloidal sulfur;
  • Carbophos.

How to protect clematis from diseases

The main prevention of clematis diseases is the correct choice of a place for planting, compliance with maintenance recommendations, moderate and regular watering.

Advice! Experienced gardeners have long noticed the benefits of planting marigolds, phloxes and peonies next to clematis. These plants help prevent overheating of the root system of the vine.

Mulching helps to retain moisture in the soil: for this, rotten manure is usually used mixed with peat in proportions of 10: 1, but other components can be used, such as sand and ash , taken in the same proportions.

When a hard crust forms on the surface of the soil, the earth is loosened. This procedure improves the access of moisture and air to the roots.

It is extremely important to take preventative measures, including:

  • check and treat seedlings with disinfectants before planting;
  • regular inspection of shoots for the presence of pests and disease outbreaks;
  • removal of diseased parts;
  • tillage in spring and autumn with a solution of Fundazol (2 g per 1 liter of water).

Conclusion

If the clematis turns yellow and dries, first of all it is necessary to understand the reasons for these changes. It is likely that the vine can still be saved, especially if this is due to improper care or the disease was detected at an early stage. The key to plant health is regular preventative treatments.
