Diseases of the leaves of Anthurium - how to treat, why they turn black and dry, what to do?

A bright exotic flower came to us from South America. From the ancient Greek language the name Anthurium is translated as “tail” and “flower”. The plant belongs to the Aroid family. The color of flowers can be the most diverse, and flowering lasts all year round and depends on the lighting. Flowers have such an unusual shape and glossy surface that they have become indispensable for florists in creating compositions.

A cut flower can stand in the water for up to a month without losing its qualities. Since it comes from the tropics, that is, certain care requirements that are very important for this species are temperature, lighting, and humidity. Failure to comply with the rules affects the beauty of the sheet plate. In order for the anthurium to please its flowering, as in the photo, it is important to determine the cause of the change in the appearance of the leaves in time, to determine how to properly treat and prevent more serious diseases in time.

Why do anthurium turn black, yellow and dry leaves and flowers

Anthurium can hardly be called a very moody plant. It is shade-tolerant and can adapt to the contents of the apartment. He earned great popularity in home gardening due to his decorative appearance. Bright large green leaves during flowering frame a large glossy flower.

But a fairly common problem when growing is that the leaves and flowers of Male happiness turn black and dry for no apparent reason. The flower quickly loses its decorative effect and may die if help is not provided in time. A flower can become ill both from improper care, and from infection with a fungus, bacteria or pests. Depending on the cause of wilting and treatment is selected.

Leaf disease due to improper care

Blackening and wilting of a plant can be associated with such non-infectious factors:

1. Non-compliance with the temperature regime. In winter, the thermometer should not fall below 16 ° C. During the period of active growth and flowering, the temperature should be maintained within 20-25 ° C. If the flower is cold, then black dots form on the leaf plate, which begin to rapidly increase in size.

   

2. Direct sunlight. Anthurium is photophilous, but prefers diffused light. Under the action of the bright sun, especially in the summer, it can get a burn of leaves, which will appear as dry darkened spots and a general weakening of the plant.

   

3. Watering with hard water. For irrigation, you need to use soft, filtered water at room temperature.

   

4. Drafts. The flow of cold air is heavily tolerated by the heat-loving plant, which immediately appears on the leaf.

   

5. Lack of lighting. It appears yellow leaves or spots of the same color.

   

6. Nutrient deficiency. Fertilizers are necessary during the period of growth and flowering. If they are not enough, then this can interfere with flowering and the color of the leaves will become noticeably paler.

   

7. Violation of the irrigation regime. A lack of moisture is just as harmful as an overabundance. Both extremes will lead to the death of a room culture due to the death of the root system.

   

Pest

Long-term exposure to pests leads to the death of the flower, since the insect eats the juice of the plant and deprives it of the ability to maintain its own nutrition. Such infections are also dangerous because they can be transmitted to another green culture indoors. Regular inspection of all colors will help identify and destroy pests in the first stage of infection.

Common infection with such insects:

1. Aphid. At the initial stage, you can notice that the leaves began to turn yellow and curl. When the damage to the aphids is already strong enough, an adhesive coating and plant appear.

   

2. Thrips. Infection with this parasite can be suspected by small black dots on the back of the leaf, which are also accompanied by light yellow spots of various shapes.
3. Spider mite. Usually, the onset of infection is missed, since it looks like small yellow dots that gradually merge into foci and begin to deform the leaves. A tick is noticeable when it envelops the affected area with a thin cobweb.
4. Shield. At the initial stage of infection, the scabbard is not visible, later it can be determined by the white tubercles on the stem and leaves.

How to treat fungal and bacterial diseases of the leaves of anthurium

Treatment of anthurium depends on the cause of the disease.

5. Treat the roots with fungicides to prevent or treat fungal and bacterial infections.
6. If there are no roots left after trimming, but there are still growth points, then you need to wrap them with wet moss and put in a transparent glass. Air every day for 15-20 minutes. Keep in a greenhouse with good humidity, under a light bulb. When new roots appear, go to step 7. If there are still living roots after trimming, then skip point 6.

   

7. Prepare a new pot that needs to be matched to the size of the roots. It should not be crowded, but too spacious can destroy the plant, since all the forces will go into the growth of the roots.
8. 30% fill the pot with drainage. Next is a layer of soil. Soil should be taken for orchids, it is best suited for a weakened anthurium.
9. Plant a plant and fill the voids with earth.
10. Care during the recovery period should be very thorough, in compliance with all the necessary rules for the maintenance of this species.
