The main reasons why begonias dry leaves

Begonia is a houseplant. Her leaves are bright, and the flowering is very lush. There are several varieties of this flower. Subject to the rules of begonia breeding, the flower will delight with a beautiful appearance. However, he may have problems. The article considers the question of why begonia leaves dry, and other difficulties that may arise during its cultivation.

Why do begonias dry leaves at the edges

The main reasons why the leaves dry at room begonia:

• the plant is subject to drafts from open windows;
• the sun's rays fall on the foliage. They burn a flower when it is on a window or loggia;
• very dry air due to battery operation;

For what reason do begonia leaves dry

• fertilizers are incorrectly applied;
• pests hit the plant;
• conditions of growth have changed dramatically;
• improper care, including poor water quality.

Diseases and pests

Various diseases and pests are one of the reasons why begonia fades. Usually a flower begins to hurt when it has too wet soil. The most common begonia diseases (leaves fade around the edges):

• powdery mildew. First there is a white coating. This disease often occurs with excessively humid air and poorly ventilated areas. Then the foliage dries and falls. To combat the disease, copper sulfate and laundry soap are used;
• gray rot. Grayish spots appear, which blacken and become rotten, and the leaves curl and dry. It is also possible to combat the disease in the manner described above;
• bacterial diseases. The most common problem is bacterial spotting. First, vitreous spots appear, which eventually acquire a brown color. The flower gradually fades. It is necessary to carry out the treatment with copper chloride.

Powdery mildew

Improper care

Improper care of begonias is another reason for the appearance of dry ends on the leaves. The main ones include:

• a sharp change in growing conditions. Many make the big mistake of putting a flower on the balcony. Some species do not tolerate such a change. Begonia is a sensitive plant, and a change in conditions affects its foliage. The flower does not tolerate when direct sunlight falls on it or when it is standing in a draft;
• too dry air. Begonia is a tropical flower, so the ideal conditions for it are high temperature and humid air. Dry air will adversely affect the leaves. Often in apartments this happens when the heating is turned on in winter or when the summer is too hot;
• insufficient nutrients. The plant must be fed when active vegetation occurs. It happens 2-3 times a month. Before purchasing fertilizer, it is important to consider the type of flower. For decorative deciduous fertilizers with a high nitrogen content are more suitable. It is better to fertilize decorative blooming with potash and phosphorus fertilizers;
• very dense earth. If the soil does not conduct air well, this leads to stagnation of water, which begonia does not tolerate. The leaves may dry out and the plant begins to wither and perish.

Leaves turn yellow

There are two main factors why begonia leaves turn yellow: improper care and illness.

Why begonia leaves turn yellow

Disease

The following diseases and parasites can cause yellowing of the leaves:

• excess water in the pot. This causes root decay. These violations gradually spread throughout the flower, which causes yellowing and decay;
• yellowing can be caused by pests such as aphids, whiteflies, spider mites. Insecticides are used to combat them.

Mistakes in leaving

The leaves may turn yellow for the following reasons that are associated with caring for the plant:

• change of place;
• the flower remained in the draft for a long time;
• sudden changes in temperature or humidity;
• after the purchase, the flower was immediately transplanted, which is why begonia received severe stress;
• pot of the wrong size. Most likely it is too big;
• when a flower was planted, inappropriate land was used. She could be acidic or heavy;
• water fell on the leaves.

Leaves fall: diseases and pests

Begonia leaves may fall off due to the appearance of downy mildew or persporosis - a fungal disease. Pathogens are contained in the earth. They become more when the humidity of the soil and air increases. The disease spreads very quickly and leads to the fall of greenery.

Begonia pests are small in size. However, they can lead to the death of the plant. Here are the parasites that lead to fallen foliage:

• greenhouse whitefly. This is a very small butterfly 1.5 mm long. She settles on the leaves and actively begins to multiply on them, eating their juices. It is possible to eliminate the insect using a normal soap solution. Larvae need to be cleaned with hands;
• leaf and gall nematodes. Leaf species settle on the stems, leaves and buds, gall species - on the roots and at the bottom of the stem. Nematodes are worms that are microscopic in size. As a result of their activities, the plant dies. First, light green spots appear, which eventually turn brown and swell. A nematode is better to prevent than to fight them. The ground into which begonia is planted must be steamed;

What does a greenhouse whitefly look like?

• false scale. This pest is hidden inside the plant. The flower ceases to grow, the leaves turn yellow and dry. To combat the pest, you need to clean it with a brush that is dipped in the infusion of garlic. Only those parts of the plant that are affected by pests are treated;
• red spider mite. If the flower is wrapped in a thin web, then a spider mite has appeared on it. It breeds in hot and humid conditions. First, the leaves become marble in color, and then turn yellow and fall off;
• greenhouse aphid. This pest breeds very actively. Each week, the female produces up to 100 insects. They suck juices. To overcome aphids, it is necessary to spray the plant with tobacco infusion;
• greenhouse thrips. They are quite large in size. The leaves lose their color, and the plant begins to fade. Thrips breed in conditions of high humidity and temperature.

Begonia withers and dries: what to do, preventive measures

When the flower begins to die, the question arises of what to do if the begonia withers and dries. First you need to do the following:

• avoid drafts;
• when the sun is actively shining on the street, it is necessary to create a shadow or partial shade for the plant. It is best to rearrange to the west or east side;
• humidify the air. This is best done by placing a container of water next to the pot. Also, expanded clay can be placed in the pallet;
• the plant must be fed every 10 days with liquid fertilizers;
• watering the flower must be defended with water. It should stand for at least a day, preferably several days.

What if the begonia leaves fall? It is necessary to understand the causes of this problem. Perhaps the plant is infected with pests, or it is sick. The most common parasites and diseases, as well as measures to combat them, are described above.

Begonia is a plant beloved by many gardeners. Caring for him is quite difficult. Various problems associated with yellowing and falling of leaves may appear. The reason for this may be improper care or the appearance of pests and flower diseases.
