What if the leaves of the peppers in the greenhouse fade?
Sweet pepper is a very popular vegetable crop that is universally successfully grown in greenhouse conditions. However, sometimes the wilting of the leaves of this bush can be noted: the causes of this phenomenon should be examined in more detail.
Why pepper leaves in a greenhouse fade: reasons
Withering of peppers cannot occur suddenly, it occurs due to the violation of certain conditions and growing technology.
- stress after changing the growth environment;
- deviations from the norm of the greenhouse microclimate;
- inappropriate soil;
- violation of irrigation conditions;
- the impact of pests and diseases;
- the formation of the bush occurs in violation of the terms or technology of the process;
- there is no tying of the crown of tall varieties.
Important! The plant may fade due to the aging of the bush.
As a rule, the wilting process occurs as follows: water droplets fall on the leaves of the pepper bush and under the influence of sunlight refracted under the conditions of the greenhouse become very hot. Under the influence of high temperature, a section of the sheet dries strongly.
If the cause of wilting lies in the insufficient aeration of the rhizome of the bush, this is due to the fact that the soil is not loose enough and a crust appears on the surface of the soil, which blocks the access of air to the roots. Inadequate breathing of the root system also causes leaves to dry out and fade.
Stress after transplant
Pepper seedlings are transferred to greenhouse soil, when each young bush has 12-14 leaves. The stem of a healthy plant in this period should reach almost 25 cm. A transplant takes place in mid-May, when the soil is sufficiently warm. If you do this earlier, withering of the bush may begin. In addition, a change in soil and growing conditions can cause stress on the plant, and it may begin to fade.
Did you know? Pepper, which in our country is usually called Bulgarian, does not come from this sunny country at all, but from America, from where the ancient sailors brought it first to Portugal, then information about it appeared in Turkey, and then it got to Bulgaria itself, where this vegetable is called simply - bell pepper or paprika.
Climate disturbance in the greenhouse
It is very important to create and control the right microclimate in greenhouse conditions.
This applies to indicators such as:
- temperature. High rates can have a detrimental effect on the plant, and first of all this will be manifested by wilting. There should be no sudden changes;
- humidity. High humidity does not allow the plant to develop well, the optimal level is in the range of 60–65%, and when it comes to seedlings - 75%;
- ventilation. Compulsory ventilation of the greenhouse should be carried out to remove excess moisture and lower the temperature indoors.
Inappropriate soil composition
Planting of pepper can be carried out in soil in which carrots, dill or onions previously grew - this will favorably affect the quality of the soil. If the soil was taken or acquired from the place where the eggplants, potatoes or tomatoes were previously grown, it contains weeds and spores of various fungal diseases - all this can cause the pepper to wither in the greenhouse.
Bell pepper reacts very sensitively to an excess of fertilizers, which can manifest itself in the form of wilting or lack of ovary on the bushes. Also, acidity should be controlled, because a violation of this parameter can be another reason for the deterioration of the appearance of the leaves.
Important! To improve the air exchange and respiration of the root system, it is extremely important to loosen the soil, and this is also facilitated by mulching the soil.
If the pepper in the greenhouse wilted, the reason may lie in the abundant watering of the bushes. Too wet soil can become a medium for the propagation of fungal diseases, as well as provoke rotting of the roots. Violation of the water balance can lead to the fact that sweet pepper will weaken and wither. Watering is recommended in the morning and evening, however, so that by nightfall the leaves of the bushes are already dry.
Diseases and pests
A change in leaf condition may be one of the symptoms of diseases such as:
- Fusarium wilt;
- verticillar wilting;
- white spotting;
- white rot.
Defeat by pests that transmit diseases or harm the plant as a result of their life activity can cause peppers to die in the greenhouse.
Did you know? Bulgarian or bell pepper has much in common with chocolate. The similarity lies in the fact that these products cause an increase in mood and a surge of energy due to the action of endorphins - “hormones of happiness” in the blood.
It can be:
- garden scoops;
What to do and how to fix the problem
In order to stop the withering of pepper, you must perform the following actions:
- First of all, it is necessary to find out the reason for the change in the type of leaves.
- To ensure the normalization of microclimate indicators in the greenhouse, to control the level of temperature and humidity, to produce regular ventilation.
- To control the quantity and quality of fertilizers that are applied under the root and in the trench next to the bush. They must be balanced, integrated and in the required volume.
- Weed the beds, ensuring the flow of air to the roots, which will ensure full plant life.
- Spray the bush from pests. To find out how to spray pepper, you need to carefully inspect the bush and note on it additional signs of certain diseases or pests, for the destruction of which it is necessary to use specific means.

In order to prevent an extremely serious condition of the plant when its leaves have wilted and are ready to crumble, a number of preventive measures should be carried out, which suggest such actions:
- Regular inspection of bushes for damage and changes in the appearance of leaves, stem and fruits. It is also necessary to monitor the condition of the soil and the general microclimate in the greenhouse.
- Peppers should not be grown in the same garden for several years in a row. You can return the landing to its original place after 4 years.
- It is necessary to carry out the complete destruction of weeds and the remains of tops after harvesting - for this they are burned.
- Preventive cultivation of the soil should be carried out regularly.
- The soil must undergo a mandatory decontamination procedure.
- At the planning stage for the purchase of seeds, it is necessary to study the data on what diseases are affected by the variety of peppers that are planned to be grown.
- To increase vitality and resistance to diseases, prophylactic spraying of bushes with Zircon, Epin, and Novosil preparations is possible.
