Why pepper drops ovaries
Pepper is an extremely demanding culture to environmental conditions. If at least something does not suit him, the plant may slow down its growth, its ovaries fall off, the fruits will ripen slowly or completely stop developing. Consider the main factors that are necessary for the favorable cultivation of this vegetable.
Peppers ovaries fall: reasons what to do
Gardeners can often face the fact that the ovary on the pepper crumbles. But this can lead to the fact that the crop will be lost, and all the efforts to grow this crop will be wasted. Under any adverse conditions, the plant begins the struggle for survival and first of all, to save energy, it discards flowers and ovaries. We will understand the reasons why pepper inflorescences fall off.

Pepper is a light-loving plant, so you need to provide lighting for this culture for about 10-12 hours. If pepper grows in a greenhouse, then you can put fluorescent lamps. If the bushes grow on the garden, then the place should be sunny, and you need to provide plants with light from the time of their emergence until the harvest. Seedlings on the windowsill require no less light than an adult plant. In addition, if we neglect this condition at the stage of growing seedlings, in the future this will greatly affect the yield.
Did you know? During the popularity of pepper, it was so highly appreciated that in the case of trade in fake pepper in some countries, merchants with their fake goods could be buried alive.
Non-compliance with the irrigation regime
Excessive or insufficient watering can also affect the ovaries. It is necessary to water constantly, but not to flood. Approximately 3-4 liters of water per square meter of area should be spent, and a little more when fruiting. The earth needs to be loosened to provide air access and to protect the soil from drying out. But it is better to mulch the soil, since loosening can damage the superficial root system.
Overly thickened landings
Too thickly planted plants will not only obscure each other, but also deplete the soil, so you need to adhere to the planting scheme. For low and medium-sized plants, a distance between plants of 20–25 cm and 30–35 cm, respectively, and between rows - 50–60 cm is suitable. For tall plants, 70 cm in row spacing and 40–45 cm between bushes will be required. Important! Too thickened plantings worsen aeration, which can cause some diseases, for example, black legs, late blight.
A sharp jump in night and day temperatures
Fluctuations of even 5 degrees can cause flowers to fall. The optimum temperature for seedlings ranges from + 20 ° C to + 22 ° C, for older plants and during pollination - up to + 25 ° C. If the temperature rises above + 30 ° C, this adversely affects pollen - it becomes barren, so the greenhouses must be ventilated to prevent overheating, and closed at night to avoid cooling. For ground peppers, you can use mulching, that is, cover the ground with various natural materials for added protection.
Pepper requires light soil with nutrients. The green parts of plants require nitrogen, the roots require phosphorus, which is also needed to accelerate the ripening of fruits, and potassium is needed throughout the growing season, so it is advisable to add rotted manure, wood ash and superphosphate to the soil in the fall. Every 2 weeks you need to make organic and mineral, as well as complex feeding. To do this, you can use ammonium nitrate, potassium sulfate, superphosphate, slurry.

Pollination does not occur
If the weather is unfavorable and there are not enough pollinating insects, the flowers can also begin to fall, so you can pollinate the plants yourself: you need to shake them a little. Pepper is a self-pollinating culture, and these actions should be enough. In greenhouses, you need to plant flowers that will attract pollinators, as well as perform regular ventilation.
Excess Nitrogen Fertilizer
With an excess of nitrogen in the soil, the tops of bushes actively develop, but this has a bad effect on fruiting. The ovaries can become frail and fall off, which is why in the fall it is recommended to make rotted, not fresh manure.
As a prophylaxis of falling of flowers, foliar feeding, i.e. spraying, with a solution of calcium nitrate is performed. This tool also helps with vertex rot. The same solution can also be applied under the root (2 g of the substance per liter of water and 1–2 liters per bush). Instead of calcium nitrate, you can use calcium chloride (3-4 g / l) and chalk suspension (1-2 tablespoons per liter in a glass per bush).
One of the most important factors for the development of pepper is the level of humidity. This is especially true in greenhouses. It should be in the range of 60 to 80%. If you go beyond the flowers will fall. At low humidity, it is possible to provide additional spraying of the bushes; at high humidity, carry out ventilation. On open ground, you can water the aisle. High humidity is dangerous by the appearance of fungi and pathogens.
Did you know? Some canaries are fed cayenne pepper. This is done in order to give the feathers a more intense red color.
Sometimes gardeners feed the crops so carefully that it also begins to drop flowers. If there is a suspicion of an excess of fertilizers, you should stop feeding, and after a couple of weeks you will see the difference. Another reason for dropping flowers is their excess on the bush. In this case, this is normal. Pepper bushes require formation, therefore, if you have not taken care of cutting off the excess, the plant gets rid of the flowers on its own. Usually the first crown buds are removed, then the plant will be strong and branch well.
In greenhouses, pepper is susceptible to the effects of greenhouse whiteflies. These insects secrete substances that cause fungus and stem damage. In addition, if a thin cobweb is noticed on the leaves - this is a spider mite. On open ground, there are even more pests: Colorado potato beetle, nematode, ants and so on. If detected, immediately treat the bushes with specialized products to kill harmful insects. With high humidity, apical and gray rot, late blight, and black leg may appear.
Important! Seeds are recommended to be decontaminated before germination in potassium permanganate. And the place where the peppers will grow should be well cleaned of the remnants of the roots and stems. They may have pathogens.
Preventive measures for this - reduction of humidity, ventilation. Other diseases that this vegetable is susceptible to include: tobacco mosaic, black bacterial spotting, pepper cancer, downy mildew. If a diseased plant is found, it must be torn out. For the prevention of diseases, it is recommended to follow the rules of crop rotation. Good predecessors for pepper are cucumbers, onions, cabbage, root crops. There should not be solanaceous. Yes, and pepper is better to plant again only after a few years.
- lighting . There should be a long daylight hours up to 12 hours. Bushes should not be obscured and overexposed in the most active solar period;
- humidity should be at the level of 60–80% . If necessary, the plants are additionally sprayed. In case of excess moisture - regular ventilation will be required;
- lack of temperature differences . Maintaining optimal air temperature +22 ... + 25 ° С. Planting only in warm soil;
- moderate regular watering without overabundance and lack . Mulching the soil;
- maintaining the distance between the bushes . Plants should not interfere with each other;
- regular fertilizer application . Moderate use of nitrogen top dressing;
- monitor pollination . In the absence of insects, pollinate on their own;
- the formation of a bush, which consists in breaking off excess buds and shoots;
- monitor the appearance of insect pests and plant diseases and take measures to eliminate these problems.
