Why can eggplant leaves turn yellow in a greenhouse

Eggplant is considered one of the most unpretentious plants. However, it can be exposed to a large number of diseases, quickly responds to changes in soil, temperature drops. Most often, culture dissatisfaction is expressed by a change in the color of the foliage - it turns yellow and curls. And even if you were able to create the necessary conditions for growing eggplant in a greenhouse, minor mistakes in care can lead to very disastrous consequences. In this article, we will learn why the lower and upper leaves of eggplant can turn white and what to do about it.

The reasons why the lower leaves of eggplant turn yellow and fall

The eggplant plant is somewhat weaker than the tomato bush. From this and the difficulties with him are much more. The problem with yellowing of foliage is often found not only in open beds, but also in greenhouse conditions, and even on a windowsill. The situation can be aggravated by the fact that the yellowed leaves begin to fall off. And in order to correctly determine the cause of the problem, it is recommended to carefully examine the culture. The reasons why leaves turn yellow can be very different. The easiest one is to adapt to a new transplant site. The vegetable may turn slightly yellow after planting. But after the seedling takes root, the eggplant turns green again.

Often, gardeners, growing seedlings, are faced with the fact that they turn yellow. This happens for the reason that a young sprout needs a lot of macronutrients and nutrients.

If there are not enough of them, the upper leaves pull all the necessary substances from the ones below. Those, naturally, turn pale, turn yellow, disappear.

Improper care of seedlings

White or yellow spots may appear in the following cases:

  • yellowing of foliage can be caused by peat soils on which eggplant is grown;
  • lack of ventilation;
  • sun or lighting burns;
  • watering and spraying in sunny weather, using cold water for irrigation;
  • low levels of potassium, macronutrients and other nutrients;
  • drought;
  • lack of nitrogen, which the eggplant needs for normal development. Only this component helps to fight yellowness on foliage.

Diseases or pests

If you notice that the leaves of a vegetable crop turn yellow, the reasons may be as follows:

  • mosaic of leaves. Light spots are formed on their surface. Ripe fruits harden. Most often, this problem occurs when growing a vegetable in a greenhouse. This is due to insufficient lighting or a drop in temperature;
  • fusarium wilting. The eggplant signals this with yellow leaves. The disease is dangerous, it can destroy the entire bush. Leaves lose color, turn yellow, fall off, twigs wither;
  • fungus. It can get into the plant from the soil not only in the beds, but also in the greenhouse. The twigs curl, dry and fall off;
  • seed of poor quality. It can be harvested from diseased plants or purchased from unscrupulous manufacturers.

Quite often, the problematic issue is related to the eggplant variety. There is a possibility that it is not suitable for the climate of your area, the composition of the soil does not meet the necessary requirements. Another problem is violation of the rules of crop rotation. Eggplants are planted on the same bed for a couple of years in a row, or tomatoes or peppers turned out to be the predecessors of the culture.

Why white dry spots may appear on the leaves

The causative agent of white spot is a fungus. The root part of the culture is affected. On the affected areas of the stem, the disease manifests itself as a whitish bloom, sclerotia (hard inclusions) accumulate inside. After a while, they soften, which disrupts the nutrition from the root system, the bush dries and withers.

As a rule, such a problem of nature for seedlings that have just been transplanted to a permanent place, and the air is still quite cool. The seedlings may even shed yellow leaves.

The affected fruit becomes soft and watery, with patches of white bloom. The disease is focal in nature, its pathogens can accumulate in the soil.

What to do with yellowed leaves

It's no secret that any problem can be eliminated if you understand the reasons for its occurrence. First of all, the plant is examined to identify the presence of white and dry spots on it. It is recommended to use a magnifying glass at such a moment. If necessary, the necessary measures can be taken to get rid of the problem.

Top dressing of the soil

  • be sure to feed the soil. Complex formulations are introduced that contain the necessary macronutrients and minerals;
  • fertilizers containing nitrogen are used;
  • many people use yeast or milk solutions as additional agents;

Eliminating watering errors

  • when watering, the right amount of moisture is supplied;
  • sometimes watering should not be done for several days to allow the soil to dry out;

Pest control

  • one of the preventive measures is fungicide treatment;
  • spraying with milk whey, infusion of onion or garlic husks, soapy water is carried out.

The solutions are applied to the surface of the affected leaves so that each area is treated. When the disease recedes, the eggplant regains strength and continues to develop.

If it is not possible to perform timely processing, protect healthy bushes from such an undesirable neighborhood. For this purpose, the affected plants are simply removed.

Greenhouse and outdoor white spot control methods

To avoid such a problem, you should properly process the soil, constantly clean the bushes from affected branches, leaves and stems, dusting problem areas with ash or chalk. Only warm water is used for irrigation.

It must be remembered that if timely measures are not taken, and the pallor of the eggplant leaves will be replaced by a pronounced yellowness, the plant may not even be saved. It will lose foliage and wither completely. Therefore, when deciding to grow eggplants, do not forget to provide them with the necessary nutrients. Remember that eggplant can reduce its yield several times from such problems.

If the eggplant leaves turn yellow in the greenhouse, the negative influence of factors such as wind and rainfall are excluded. However, overheating of the seedlings and their drying out can occur from excessive ultraviolet radiation and poor ventilation of the room. In such cases, the leaves of the plant acquire a yellowish color and curl. In addition, gardeners themselves can overdo it with watering eggplant and cause acidification of the soil, which is harmful to plants. When this happens, even at a distance, an unpleasant odor is felt from the soil and whitish salt streaks appear on it.

It also happens that eggplants turn yellow in the greenhouse due to the temperature difference in it. Above, the seedlings are intensely warmed by the sun, and below, along the floor, cool air is drawn from the street. The blue ones are very sensitive to cold, they love light and warmth, so such a deficiency can affect the production of chlorophyll in the leaves and cause them to turn yellow.

Often, a lack of oxygen for the roots of plants, due to their close location to each other, can cause discoloration of leaves, lethargy or shrinkage of shoots.

Why do the lower leaves of eggplant begin to turn yellow

Most often, eggplant leaves turn yellow from the bottom row. This is because the root system is the main site for nutrient absorption. And first of all, all their reserves necessary for full growth and fruiting are transferred to the root. Accordingly, the lower leaves lose power and eventually begin to fall off.

Most pests are found on the soil layer. When a plant begins to damage a spider mite or other intruder, eating begins from the bottom row. Therefore, it is important to look at the plant constantly and notice the disease in time in order to take the necessary measures.

Why do eggplant leaves turn yellow and wither in the greenhouse?

All the time eggplants turn yellow in the greenhouse, I don’t know what to do.

Eggplants are very delicate and capricious to grow. Much more capricious than tomatoes. Typically, the leaves can turn yellow and wither from the heat. For example, I had such a careless experience when eggplants were planted in a greenhouse, but they began to hurt a lot - turn yellow, lose leaves. It turned out that that greenhouse filler (last year's grass, cow dung) began to burn. This made the roots of the plants very uncomfortable, watering did not help. Transplanted into open ground, the poor plants recovered for a long time, the harvest was very frail - one or two eggplants from a bush.

Therefore, see if the soil under the eggplants is also on fire.

Perhaps it is too hot in the greenhouse itself - you need to arrange ventilation.

If the lower leaves turn yellow, this indicates that there is not enough nutrition for the roots. This means that you immediately feed your plants with microelements - you can buy top dressing at any specialized store.

But the leaves still wither from insufficient watering. Check the watering regime, do not allow the soil to dry out.

There can also be such an unpleasant disease as verticillosis. At the same time, the leaves also wither and turn yellow.

If there is a bear in your area, maybe it is eating up the roots? This version can also be checked.

Eggplant is a whimsical vegetable culture. They are demanding in moderate watering, clean weeding. And, if the foliage began to turn yellow in the culture, one of the first reasons is the appearance of pests in wet peat soil, and the culture begins to die. In this case, temporarily delay watering and

Mistakes happen with novice summer residents. Unknowingly to care for a vegetable crop, they are watered in a closed ground with cool water, thereby harming the plants and the leaves turn yellow and dry out.

Of course, without seeing photographs of yellowing eggplants, one can assume various reasons for this phenomenon. But for some reason it seems to me that this is not a matter of fusarium, because with it yellowing is accompanied by necrosis of the leaf tissue, and such a moment would definitely be mentioned.

But since the leaves just turn yellow and wither, and it happens in the greenhouse, then the most likely reason may be too high a temperature or lack of watering. Eggplant, as other respondents have already noted, is an unusually capricious culture that requires a very careful attitude. It is worth missing a moment and now they get sick, weaken, turn yellow and fall off. By the way, about yellowing and falling of the lower leaves - such a coincidence may indicate that the eggplants do not have enough nitrogen for growth. That is, the nitrogen missing in the ground is taken by the growing plant from its own lower leaves. Feeding with nitrogen fertilizers will help here.

There may be several reasons for the yellowing of eggplant leaves when grown in a greenhouse. The culture is capricious, especially in the conditions of Central Russia, where they lack warmth and light. Personally, I gave up growing it long ago. Eggplants are relatively cheap in summer and they were brought from the southern regions, so they ripened well.

But if you definitely want to grow eggplants in your shrubbery, then they need to create optimal conditions for growth and fruiting. And this:

  • enough light
  • optimal distances between plants, there should be no thickening
  • correct and regular watering, neither waterlogging nor drying out should be
  • sufficient nutrition for the roots - nitrogen, phosphorus, potassium plus trace elements
  • pest and disease control
  • the optimal growing temperature is 22-25 degrees. FROM
  • good ventilation in the greenhouse.

If at least one of these conditions is violated, the leaves may begin to turn yellow. Most likely, if you exclude fungal diseases, your greenhouse conditions are not entirely favorable for the growth of eggplants (not enough light, nutrition, temperature conditions, excessive humidity, close planting, etc. Try to change the conditions in the greenhouse.

External factors

The soil where the eggplant will be planted must have a high level of fertility and be saturated with minerals. As the plant grows, the addition of certain minerals will be required, especially nitrogen, which is responsible for the correct distribution of nutrients to the leaves, stem and ovary.

Leaves may turn yellow due to lack of nitrogen. The plant predominantly begins to turn yellow from the lowest leaves, but over time, the yellowness rises higher, the leaves fall off. If such changes are noticed, it is necessary to urgently take measures to prevent the death of the plant. For this, nitrogen-containing feeding is carried out. As a preventive measure against yellowing of the leaves, it is recommended to add nitrogen during growth or a few weeks after planting.

Yellowing of leaves on seedlings is sometimes observed. It can appear when climatic conditions change, for example, yellowing occurs when home unhardened seedlings are planted in a greenhouse. In order to avoid yellowing, it is worth adhering to the basic care recommendations, and the leaves will gradually acquire a natural green color.

Leaves may turn yellow when infected with Fusarium wilt, which is predominantly seed borne. Therefore, before planting seeds, it is necessary to process them with potassium permanganate. In the process of transplanting, the roots are carefully buried and the soil around is loosened to provide air access after watering.

Useful Tips

When the reason is determined why the leaves of eggplants turn yellow and wither, you need to start the fight without delay.

Experienced gardeners give some tips on how to minimize physical and material costs in this process.

  • First of all, they recommend planting eggplants correctly. It is necessary to disinfect the seeds in advance, choose a soil that is suitable for this particular crop, and also decide on an area where there will be enough sunlight. To get rid of the fungus, when planting in the holes, add "Trichomerdin".
  • Timely feeding will help provide the seedlings with the necessary beneficial components, which will affect their growth and general condition. In this case, the main thing is to adhere to the instructions that manufacturers place on packages with fertilizers.
  • Only warm water should be used for irrigation. The procedure should be carried out in the morning or in the evening, but not during the hot time of the day and under the scorching sun.
  • If signs of disease appear on individual specimens, they must be removed in time in order to prevent the infection from spreading to other sprouts. And you also need to periodically inspect eggplants in order to exclude the visual manifestation of diseases.
  • The earth should be loosened from time to time. This will help saturate the soil with air and moisture, which will have a beneficial effect on plant health.

Why the prevention of diseases that affect the leaves and stems of plants is important is understandable. Surely does not raise the question "Why?" following the rules "do not water with cold water", "regularly pinch", "loosen the ground", "remove weeds", "give enough sunlight".These are natural things that fit into the concept “It is easier to prevent than to cure”.

As a preventive measure, try to ventilate the greenhouse as often as possible. Musty air negatively affects the appearance of plant leaves, in addition to everything else, condensation is removed from the walls of the greenhouse, which has a positive effect on the growth of eggplant, but negatively on the growth of fungal microflora.

Maintain a stable air temperature, do not allow sudden changes in it, as this causes significant harm to eggplants. Watch out for watering, do not be afraid to add organic elements, water with infusions and broths. Thus, you will always maintain a growth-friendly amount of nutrients in the soil.

Be sure to remove weeds, as well as the tops of dead plants to avoid the invasion of harmful insects or fungus. Plus, it saves more micronutrients for the growing eggplant.
