Diseases of clematis

Why do clematis leaves turn yellow, what should I do? If the lower leaves of clematis turn yellow and dry, there can be many reasons for this problem. Why does clematis turn yellow:

  • incorrectly selected site for planting;
  • watering is carried out during a period of strong sun activity;
  • there is not enough space for the plant;

Clematis

  • excessive irrigation, stagnant moisture;
  • applying an excessive amount of fertilizer;
  • unprepared soil for planting;
  • the development of fungal diseases;
  • damage by pests.

If the leaves of clematis turn yellow, what should I do? - First of all, you need to find out the reason. After its elimination, the plant will grow and develop fully. Often, despite the care and the right place, the treatment with chemicals, the leaves continue to turn yellow, brown and dry out.

Dried leaves of clematis

In this case, you should think about the correct feeding of the flower. Every year it renews its shoots, spends a lot of resources on long-term flowering. It needs replenishment with mineral elements: magnesium, sulfur, nitrogen, iron, manganese, zinc and copper.

With a lack of magnesium, spots first appear on the leaves, then yellowing and wilting begins. The tips dry out and curl. This happens if you plant a bush in sandy soil. To avoid this problem, you need to add magnesium sulfate.

If young leaves begin to turn red or yellow, brown spots appear, this may indicate a lack of sulfur. To replenish it, you need to feed the plant with calcium sulfate or ammonium sulfate.

Important! Redness and yellowing are noted with a lack of nitrogen. The plant receives it by introducing peat, humus, manure. In spring, you can feed clematis with calcium nitrate, urea.

If the upper part of clematis begins to turn yellow, gradually going down, this indicates a lack of iron or that the soil is calcareous. The fight against this situation is carried out with the help of fertilizers that will acidify the soil - sulfuric acid, iron chelate. When manganese, zinc and copper are deficient, the leaves can also turn yellow and dry out. You need to treat the plant with copper sulfate, humus, zinc sulfate.

Fungal diseases of clematis and their treatment

Verticillium wilting, or wilt

Clematis wilt is a very serious disease.

Wilt on clematis

Wilt tends to spread quickly, as a result of which the plant dies. Most often, wilting begins to appear at a time when abundant flowering and maximum shoot growth begins. At this time, the root system is under increased stress and becomes vulnerable to the development of diseases. Excessive soil irrigation can also provoke the appearance of pathogenic flora. Wilt manifests itself with the following symptoms:

  • wilting of the upper shoots;
  • drying of leaves;
  • brown shoots.

The fight against wilting should be carried out as quickly as possible. The first thing to do is remove the weeds around the bush. Next, treat it with a solution of Fundazole or Previkur. In spring and autumn, water the bush with a solution of wood ash, dolomite flour. If the infestation is too strong, the plant dies. It needs to be dug up and disposed of.

Phomopsis

Very often the plant infects the fungus Phomopsis. It appears as brown spots on large leaves; as it develops, the leaves turn black and fall off. The fungus also spreads to the shoots.

Development of phomopsis

The bush is treated with fungicidal solutions. Fallen leaves and affected shoots must be disposed of. Water stagnation should not be allowed, if necessary, you need to transplant the bush to a sunny area.

Gray rot

With high air humidity, with prolonged rains, clematis can be vulnerable to the development of gray rot. Buds, leaves and stems are covered with gray-brown spots.

Gray rot on clematis

The causative agent of the disease is a fungal microorganism, its spores quickly spread to leaves and stems. The fight against the disease is carried out with the help of fungicides - Fundazol, Previkur.

Fusarium

Clematis undergoes fungal wilting caused by Fusarium. The mycelium of the fungus penetrates into the weakened tissues of the plant, disrupting the conductivity of blood vessels, metabolism. More often, such a disease appears on large-flowered species, on young plants.

Description of symptoms:

  • rolling leaves;
  • the appearance of brown spots on the edges;
  • wilting of shoots and leaves.

Important! The fight is carried out using fungicides. You also need to remove all affected shoots and leaves, dispose of them. Be sure to disinfect the instrument.

Rust

Affects ground parts of the plant.On the deciduous mass, the stems, bright orange spots appear. Gradually, these parts of the bush die off. The cause is fungal spores, weeds are carriers.

Treatment:

  • remove all parts of the bush that have signs of the disease;
  • treat with Fundazol, Previkur, Ridomil;

Powdery mildew (Erysiphales)

Clematis are vulnerable to powdery mildew.

Powdery mildew on clematis

Important! Initially, a white bloom appears on the leaves, underneath the tissues die off. Also, the disease spreads to the shoots. The causative agent is a fungus.

Treatment:

  • spraying with Fundazol, Previkur, Ridomil;
  • treatment with copper chloride.

Ascochitosis

It appears as spots on the leaves in the middle of summer. The causative agent is a scochite mushroom. The result of his vigorous activity is dark brown spots.

Treatment:

  • remove damaged parts of the plant;
  • spray with a copper-containing preparation;
  • treat with a solution of copper sulfate.

Alternaria, septoria, cylindrosporiasis
