Why the leaves of the eggplant in the greenhouse wither: the main mistakes

Causes of wilting

Growing in a greenhouse, eggplants are practically not exposed to negative external conditions, such as strong winds, hail, rain, scorching sun, birds and most insects. However, it is full of dangers affecting the appearance of the plant and inside the greenhouse.

First of all, the leaves may wither due to too high a temperature in the greenhouse. Despite the fact that eggplant is a heat-loving crop, an increase in temperature above 30 ° C adversely affects the functioning of the plant. Dry hot air causes the leaf plates to first wither and then die off.

The lack of moisture in the soil is another reason for this eggplant behavior. In order for all vegetative processes to work as expected, the vegetable needs regular watering with warm water. Without saturating it with moisture, nutrients and liquid are concentrated in the stems, roots and inflorescences.

An acute shortage of nitrogen fertilizers leads to the fact that eggplant leaves are depleted, do not receive the necessary complex of microelements to maintain a healthy shape. Nitrogen acts as a stimulant and regulator of adequate distribution of nutrients in any plant, so its deficiency disrupts the working pattern of eggplant development.

Do not exclude wilting of the leaves, as a consequence of plant transplantation. Since the conditions for growing in pots at home and in the ground in a greenhouse are different, the plant must go through a period of adaptation and acclimatization. After the eggplant takes root in the new soil, the leaves will again become vigorous and green.

Also, the composition of the soil can be the cause of wilting. Eggplant grows well on crumbly soil with a high content of mineral and organic fertilizers. At the same time, they do not take root very well in the beds, where before that tomatoes, potatoes, and peppers grew.

Eggplant leaves can wither with a disease of Fusarium wilt. It is quite common in greenhouse plants. Fungal microflora parasitizes on the root zones of the eggplant, affecting all parts. It is transmitted through contaminated soil, seeds from diseased plants, and is also stored in plant debris if you did not remove them from the beds.

Troubleshooting methods

What to do, eggplant leaves wither? First of all, try to identify the cause or their complex, which thus harm the plant. At high air temperatures, regular ventilation should be carried out in the greenhouse in order to naturally lower it. To enhance the effect, you can set containers with cold water around the perimeter of the greenhouse. As the water evaporates, the air will cool and also humidify, which will undoubtedly have a positive effect on the growth of eggplant.

Insufficient watering and the use of cold water as a cause of wilting of the leaves requires a complete change in the gardener’s habits. When planting a culture that loves abundant moisture, care should be taken to ensure that the earth does not dry out. As for the temperature of the water, then focus primarily on the temperature of the earth. A significant difference in temperature leads to the development of fungal microflora, which provokes diseases such as powdery mildew, downy mildew, anthracnose, copperhead, root and gray rot. This causes great harm to the root system of the eggplant, it can begin to rot. Remember – the temperature of the water should be equal to or slightly higher than the temperature of the ground in the greenhouse.

Growing absolutely any crops in a greenhouse, monitor the composition of the fertilizers that are in the soil. Since mineral and organic materials make up the lion’s share of healthy eggplant growth, their lack can have dire consequences. In the case of a lack of nitrogen, it is important to carry out foliar or root top dressing. Mix 3 tbsp. spoons of superphosphate, 1 teaspoon of ammonium nitrate and potassium sulfate in 10 liters of water. After watering the plants in the greenhouse, at the rate of no more than 1 liter of liquid fertilizer under one bush.

Be sure to observe crop rotation: do not plant eggplant twice in the same place or after potatoes, tomatoes, peppers. The best predecessors of eggplant are cabbage and cucumbers. If you have lost sight of this moment, then carry out foliar feeding of plants with organic fertilizers: chicken manure extract, boric acid, yeast solution.

With the development of fungal diseases, it is necessary to treat all plants in the greenhouse with fungicidal preparations, for example, Topsin-M, Trichodermin, Fitosporin, etc. Depending on the type of disease, auxiliary methods of treatment differ. So, with fusarium, late blight, it is important to remove all weeds, infected leaves and shoots, and then treat the plant with chemicals and infusion of onion peel. With different types of rot (gray, white, root) – remove the damaged parts of the eggplant, treat the plants with Horus, Antrakol preparations. In any case, it is important to monitor soil moisture, normal access to light and fertilizer.

As folk remedies for the fight against fungal diseases use:

• Infusion of onion peel: 0,5 l of onion peel is infused in 3 liters of hot water for 2-3 days. The resulting infusion is filtered before use.
• Infusion of garlic: 3 heads of garlic are ground into a pulp, poured with 2 liters of hot water, insisted for 8-12 hours. Before use, filter, dilute 1:3.
• Milk whey: 1 liter of sour milk is diluted with 1 liter of water, infused for 12-14 hours. Before use, filter, add 1-2 tablespoons of liquid soap.
• Yeast solution: 10 g of dry yeast is dissolved in 10 liters of warm water, infused for 2 days. Dilute 1:10 before use. You can also use 100 g of live yeast diluted in 10 liters of water, the solution is infused for 1-2 days, then filtered. Suitable for both foliar feeding and spraying plants.
