Why do eggplant flowers fall in a greenhouse

Growing in a greenhouse, many plants receive a safe environment, a stable climate, and all the necessary nutrients for a stable and healthy development. Some crops do not require special care, others, on the contrary, are quite picky and react to any change quite sharply - these include eggplant. Why flowers fall and eggplant leaves wither in a greenhouse, as well as how to deal with it, you will learn in this article.

Causes

When looking for the source of this strange plant behavior, you should pay attention to its basic needs. Eggplants require a lot of light, and if in a glass greenhouse, access to the sun's rays is not limited by anything, then with a film or polycarbonate coating, everything is a little more difficult due to their reduced light transmittance. Plant leaves can also create unfavorable shading, especially if you do not pinch and pinch.

Last but not least, eggplant flowers fall due to watering. It would seem, what can be difficult in watering the beds in a greenhouse? However, there are a lot of pitfalls here too.

Firstly, many gardeners do not monitor the temperature of the water with which they water the bush. The soil and air in the greenhouse have a stable temperature, which fluctuates slightly during the day and is in the range of + 25-35 ° С. In this case, the water temperature should not be lower than +20 ° C, so as not to cause inconvenience to the plant.

Eggplant roots are very sensitive to temperature extremes, so try to keep the water warm.

Moreover, watering with cold water often leads to the fact that a weakened plant becomes extremely vulnerable to fungal diseases, which are quite difficult to treat.

Secondly, when asking why eggplants shed their inflorescences, rarely does anyone think about the watering scheme. On the one hand, gardeners often water the beds too often, so that the bush simply cannot absorb any more moisture, which means it “floats” in the water and begins to rot. On the other hand, watering can be haphazard, alternately leaving the plant without water for a long time, then watering almost every day. Both options lead to the same answer to the question of why leaves and flowers wither - lack and excess of moisture disrupt the vegetative processes of eggplants.

Sometimes flowers fall off due to high humidity. During the flowering and pollination period, the vegetable needs an extremely dry external environment (with the exception of moist soil) so that pollen does not settle inside the bud. Under the weight of wet and swollen pollen, the inflorescences leave the bush. To avoid this development of events during the flowering period, equip the ventilation in the greenhouse. This will have a positive effect not only on the inflorescences, but also on the eggplant leaves.

If you follow the watering conditions, monitor the air humidity and lighting in the greenhouse, but the inflorescences continue to decorate the ground, and not the bush, carefully examine the leaves of the plant. If discolored dots appear on them, then a spider mite has settled in the greenhouse - one of the most annoying enemies of eggplant. The longer the insect lives on the plant, the more seriously the leaves change - they become covered with a marble pattern and cobwebs along the lower part of the leaf. To combat spider mites, the bush and walls in the greenhouse must be treated with Fitoverm.

What eggplants need

So, having designated a few "why", it is worth taking a closer look at what else the blue ones may want for the normal formation and pollination of inflorescences.First of all, it is, of course, good lighting, regular watering with warm water and the absence of weeds in the garden. Then the leaves, and inflorescences, and ovaries will remain in place until the due date. Also keep track of the temperature inside. For comfortable growth, blue ones need +25 ° C during the day and at least +15 ° C at night. Low temperatures are another reason why the plant can shed the inflorescences.

Do not overlook the presence or absence of minerals in the soil. No plant can independently develop enough mineral compounds to support growth, flowering and fruiting. Three key elements for any plant: phosphorus, nitrogen and potassium.

For the first weeks of life, seedlings need phosphorus to develop a strong root system, release leaves and form a firm stem. Moreover, phosphorus fertilizers help the little blue to maintain a normal metabolism and distribute the resulting trace elements throughout the body.

Nitrogen contributes to a set of green mass. It is when this element is saturated with large leaves that can absorb more solar energy. Its presence is especially important in the first half of the growth of the vegetable, while during the flowering period it is better to stop nitrogen fertilization.

Potassium is essential for the formation of large buds and large fruits. Its lack is one of the reasons why the inflorescences wither and crumble. Boron is also needed to accelerate growth, iron and manganese to saturate the fruit with useful trace elements.

After planting seedlings in a greenhouse, feed them with liquid mullein or chicken manure extract, you can also use a yeast solution. Be sure to add a tablespoon of phosphorus, potassium and nitrogen to the mixture. On the eve of the appearance of inflorescences, add phosphorus and potassium, mixed with an extract of chicken manure and wood ash. Finally, the last dressing is carried out during the fruiting period, using the same mixture.

By following these simple rules, you can grow a crop without problems.

When eggplants are kept indoors, due to the absence of insects, pollination may not occur and the flowers will fall off. What to do in this case, watch this video.
