Begonia is considered a popular flower, both in the dacha and for room cultivation. Everything is beautiful and surprising in it: the leaves, the flowers, and the shape of the bush. But when growing it, practically every florist periodically faces various difficulties. The most pressing problem in the cultivation of a flower is falling and drying leaves. To prevent death, it is necessary to find out why leaves are drying off in begonias and what factors influence their falling off.
Similar problems most often occur with plant care errors. Begonias dry and fall leaves for the following reasons:
- improper conditions of detention;
- micronutrient deficiencies;
- disease.
We select growing conditions for
One of the characteristic features of improper care is a dramatic change in conditions. Strong stress indoor flower can experience if you put it on the balcony. Since certain types of begonias are intended for growing only indoors, and even in suitable weather conditions, begonias dry leaves and flowers. What to do in this case?

If begonias have dry leaves in winter, then the cause of this problem is its innate high sensitivity to dry air. Therefore, in winter, it is better to place pots with plants away from heating devices. But if this is not possible, then to increase the humidity next to the begonia, you can put water containers and spray the bush daily.
This problem is also characteristic of the outdoor plant variety. The reason why begonias on the street dry leaves, often turns out to be insufficient soil moisture and too dry weather. The lack of irrigation can be seen on the dried tips of the leaves, after which they turn brown. The solution to the problem will be sufficient watering and moistening with a sprinkler in the evening or early morning leaves. However, it should be remembered that the roots of the plant do not like stagnant water, so watering should be moderate, otherwise the leaves of the begonia will begin to fall.

Also suitable potassium nitrate, which is made under the plant no more than once every two weeks. To maintain the leaves in extreme heat, you can use spraying humate, epitome, zircon.
Getting rid of diseases
Drying and falling off the leaves of begonias can result from diseases and pests resulting from improper care and adverse weather conditions.
Mealy dew .For this disease is characterized by the appearance of spots with a white patina. As the pathogenic bacteria spread, the spots merge and cover the entire surface of the leaf. Gradually affected leaves turn brown and dry. In this case, spraying with basezol( 0.05–0.1%) or seastan( 0.05%) will be effective countermeasures. During the growing season, the leaves of the plant can be slightly sprayed with powdered sulfur or sprayed with colloidal sulfur solution( 0.3 - 0.5%).As a proven tool used soap-copper liquid, which is prepared from 1 liter of liquid, 2 grams.copper sulphate and 20 grams.tar( green) soap.
Gray rot .Leaves of begonia may also dry and fall off due to the defeat of gray rot. The most favorable factors for the development of the disease may be warm and humid weather, during which many dusty spores are formed. Its beginning is easy to see on the watery spots with a gray bloom that occurs on the tops of the shoots and leaves. With further spread of the disease affects the stems of plants that begin to rot and break. Foliage, flowers and buds are twisted and twisted and fall. An effective way to combat gray rot is spraying Bordeaux liquid( 1%) or soap-copper mixture, the preparation of which is described above.
In conclusion, I would like to note. You should not be alarmed when there are several dried, lower leaves in begonias. Most likely, there is a normal process of plant development, during which the old leaves die. Observe him for some time and take action if necessary.
