Begonia has been a favorite of all gardeners for many years. But flowering can only be achieved by observing the rules of care and cultivation. Failure to comply with agricultural standards most often leads to disease. Begonia diseases can have a very different nature of origin.
Home begonia - how often sick
Indoor begonia diseases often occur when pests are invaded or due to non-compliance with the growing conditions. Begonia can also be sick due to varietal characteristics or failure to comply with the rules of reproduction.
Flowering healthy plant
Leaves turn yellow, dry and curl
Due to lack of moisture, begonia leaves curl. Its deficiency can be observed both in soil and in air. At the initial stage of the disease, the leaves begin to turn yellow, and then twist. To save the flower, you need to quickly remove it from the sun. Timely sprinkling of begonias will also help control the level of humidity.
Low humidity
Buds fall
The main reason why begonias flower buds fall is the lack of necessary elements for the plant. Transplanting a flower into new soil will help save the situation. To restore the required level of nutrients, weekly top dressing is used.
Other reasons why the buds of tuberous begonia fall off:
- Water got on the plant during the flowering period.
- Indoor air dryness.
- The soil is waterlogged or, conversely, watering is not enough.
- The plant is often moved from one place to another.
- The presence of pests is another reason why begonia drops buds.
Stains on the leaves
The main causes of spots on the leaves of the flower:
- If there are brown spots on the begonia on the leaves - this is the first sign of non-compliance with the ventilation regime. This is usually caused by improper placement of the flower.
- Increased humidity in the room may cause gray spots.
- The brown tips of begonia leaves are a consequence of the low humidity in the room. With untimely treatment, the leaf plates completely turn red, and then twist and fall off.
Diseases of Blooming Begonia
During the period of active formation of begonia inflorescences, an increased amount of micronutrients and substances is required.
A common cause of wilting flowers and unblown buds is improper growing conditions.
Proper placement of begonias
Begonia is demanding on high humidity. To maintain the required level, it is recommended to arrange sprinkling of the flower from time to time. The "dew effect" is a great way to moisten not only the air around, but also the substrate.
Rotting leaves, stalk, roots
Most often, rotting branches is the next stage of damage to the root system. Why does begonia rot? The reason is most often hidden in an excess of moisture.
Urgent resuscitation in the form of a transplant into a new pot will help save the flower. The plant must be completely cleaned of earthen coma and treated before transplantation with fungicides.
On a note! If the infection stage has already reached a critical level, and the flower has begun to fade, you can try to grow a new plant from its leaves or part of the stem.
Other diseases
The presence of small bright spots on the leaves is a sign of powdery mildew. For treatment, it is necessary to make a solution of 2 g of copper sulfate, 20 g of laundry soap and 1 liter of water. Timely spraying begonias with such a composition will save it from falling leaves. From powdery mildew fungicides also help.
Infection with gray rot appears on the plant with white spots. Over time, they begin to darken and become brown.
Important! With a running illness, the flower can even dump all the greens.
You can help the plant with a mixture of 20 ml of 1% Bordeaux liquid, 2 g of copper sulfate and 20 g of tar soap, dissolved in 1 liter of water. She needs to spray a flower. The solution can be replaced with any fungicides.
Untreatable diseases
When signs of certain diseases appear, it is urgent to destroy the entire infected flower. There are several reasons why begonia is killed.
If bright yellow spots and dead edges of the leaves appear on the leaf plate, it will not be possible to save the flower. Ring spotting not only destroys the flower, but also affects neighboring plants.
Ring spotting
The appearance of watery spots on the leaves is caused by a disease that is incurable. Bacterial spotting affects not only leaves, but also inflorescences.
Bacterial spotting
Brown spots appearing on the leaves of begonia are usually caused by the leaf nematode. At the initial stage of the disease, partial falling of leaves occurs. The disease occurs due to contamination of the soil and non-compliance with the temperature regime. The flower is subject to immediate destruction.
Pest diseases and their destruction
The most common pests that infect begonia are spider mites and common aphids.
When a spider web appears on the bottom of the leaf, it is urgent to conduct treatment of the plant. A solution of onions has proven itself as a pest protection. To obtain it in one liter of water, 20-30 grams of finely chopped onion are soaked. The solution must be infused for 7-10 days. Before processing, the mixture is filtered. Spraying is carried out until all pests have disappeared. The course of treatment is 7-14 days. Of the pesticides, Decis is best used. The drug also helps against other pests.
Spider mite
One of the most dangerous pests is aphids. The insect multiplies very quickly and damages not only the stems, but also the leaves of the plant. Aphids most often appear in the spring due to increased humidity and low temperatures. For preventive purposes, it is recommended to spray the plant with a solution of nettle or parsley. The fight against a harmful parasite consists in the constant treatment of begonias with a soap solution.
When wrong care is to blame
Begonia is considered a moody plant. A flower requires constant attention and care. In their absence, he begins to hurt. Timely changes in the conditions of detention will help save the plant from death.
Appearance of the plant with proper care
The main problems caused by errors in care:
- Sharp stretching of shoots - occurs due to improper lighting, when transplanting into a tight container or lack of trace elements.
- Sticky coating on the leaves - appears at the initial stage of flower decay. The main reasons are waterlogging of the soil, an increased level of humidity in the room. You can cure the flower by removing the affected parts and adjusting the irrigation and lighting mode. Also, recovery is facilitated by treatment with a solution of Euparen, Fundazole or Topsin.
- Begonia stops growing - this is caused by waterlogging of the soil. Soil change and a significant reduction in watering will help restore development.
- Redness of the leaf plate in the spring - most often due to an excess of light.
- Powdery mildew infection is also caused by errors in care. Save the situation will help reduce watering, reduce humidity in the room, increase the temperature and the complete absence of drafts.
- The appearance of a false shield in a flower is caused by a draft or the presence of an infected plant near a begonia. The insect lives inside the stems and ultimately leads to the death of the entire bush. When the first signs of infection appear, it is necessary to manually treat the affected areas with infusion of garlic or onion. The operation is carried out until then, until you can completely get rid of insects.
- The appearance of whiteflies, which multiplies very quickly, is the result of improper care and non-compliance with the rules of elementary agricultural technology. You can save a flower if you process it with a strong soapy solution. Each damaged leaflet must be urgently destroyed. Sprinkling with a soap solution is carried out until all pests disappear.
On a note! Stopping the growth of begonia is sometimes caused by a period of rest. In the spring, flower development will resume.
Alternative methods of treating certain diseases
Begonia can be saved from pests with the help of folk remedies. The most effective solutions:
- Tobacco infusion. For cooking, you need to dilute 30 g of tobacco dust in 5 liters of warm water. The concentrate should be infused for 7 days. Watering is carried out under the root.
- Concentrate of green soap. 30 g of laundry soap is dissolved in 2 liters of warm water. Any plant residues are added to the resulting solution. Tincture is prepared within 10-12 days. For treatment, begonia is sprayed with the resulting composition.
- Infusion of onions or garlic. Finely chopped onion or garlic (200 g) for 7-10 days is infused in 5 liters of warm water. The resulting preparation is diluted with water in proportions of 1:10 and filtered. For sprinkling, a fine atomizer is used.
