Yellowing of pepper leaves in most cases leads to drying and death of the plant, therefore, emergency measures should be taken to preserve the crop. Timely action will help minimize losses and return plants to a healthy appearance.

General information

Pepper is a heat-loving and light-loving crop, in the conditions of the middle lane it is grown in greenhouses. The plant does not require labor-intensive care, the main agrotechnical measures include:

– regular watering;

– timely and balanced nutritional supplements;

-correct formation of bushes;

– loosening the soil and removing weeds.

Incorrect or untimely fulfillment of these conditions can lead to a change in the color of the leaves and the death of peppers. Other reasons why peppers turn yellow in a greenhouse can be temperature changes and high humidity, watering with cold water, diseases and pests of vegetable crops.

Let’s take a closer look at the most common mistakes when growing peppers.

1. Non-observance of temperature and air humidity

Sharp temperature fluctuations, due to the heat of the day and a strong cold snap at night, lead to yellowing and the gradual death of the green mass. In addition, low temperatures can cause plant death. Unfavorable for plants and excessive humidity in the greenhouse. Exceeding the permissible parameters leads to a decrease in leaf turgor and their gradual yellowing and falling off.

2. Lack of nutrition

Another factor that causes leaves to turn yellow is nutrient imbalances. The lack of fertilizers in the soil does not allow vegetable crops to fully develop, a change in the appearance of plants indicates a nutrient deficiency. Peppers are most often iron deficient, which leads to chlorosis followed by discoloration of the leaves.

3. Development of diseases

Peppers can often be affected by fungal or bacterial infections. To take timely action and reduce crop losses, plantings should be regularly inspected for diseases. The most common diseases are gray rot, late photo blight, blackleg, fusarium wilt, dry or brown spot. In addition to diseases, pepper can also be affected by pests: aphids, bears, slugs, spider mites, tips and slugs.

Yellow pepper in the greenhouse what to do

A few proven recommendations if the pepper turns yellow in the greenhouse what to do.

1. In case of nutrient deficiency, it is imperative to fertilize plants. To do this, you can use the drug “Aelita”, intended for vegetable crops. This modern drug is balanced in composition, contains the whole complex of micro and macro elements.

2. In some cases, the change in leaf color is associated with a nitrogen deficiency in the soil; to correct the situation, plants should be fed with mullein or bird droppings. These fertilizers are rich in nitrogen, after their application, the plants quickly increase their green mass.

3. As a top dressing, you can use the Kemira fertilizer, it stimulates metabolic processes at the cellular level.

4. Systematic ventilation of the greenhouse will help eliminate excess moisture, while it is important to ensure that the plants are not in a draft.

5. To provide peppers with moisture, drip irrigation systems are equipped in greenhouses. The system allows you to supply water to each bush, it can also be used to feed plants.

6. To prevent plants from dying from the cold during spring or autumn frosts, pepper bushes are covered with plastic wrap or lutrasil. Feeding with wood ash, which is carried out when there is a threat of frost, will help increase the resistance of peppers to low temperatures.

Disease prevention

Weakened plants become easy prey for various pests, are affected by bacterial and fungal infections. To prevent these problems, a set of preventive measures should be carried out in a timely manner.

Preventive measures include the following:

– after harvesting, all plant residues are removed from the greenhouse, especially if the previous crop is cucumbers;

– after cleaning, the greenhouse structure is disinfected with a solution of bleach;

– to prevent the appearance of pests and pathogens, pepper bushes are sprayed with herbal solutions or infusions of onions or garlic;

– to combat diseases and pests, modern biological preparations that are harmless to plants and humans should be used;

– loosening the soil improves aeration of the root system, promotes better absorption of moisture. Loosening helps to identify and destroy plant pests in a timely manner, for example, a bear;

-regular inspection of plantings contributes to the early detection of pests and diseases of peppers, which allows you to deal with them much faster and more efficiently, without crop losses;

– for the destruction of harmful insects in greenhouses and hotbeds, it is recommended to install special traps.

Seed processing also plays an important role. When planting, preference should be given to zoned varieties and hybrids that are resistant to diseases and pests.

Gardeners with experience to fight diseases try to use folk and biological methods. Chemical agents are highly effective, but tend to accumulate in different parts of the plant, including fruits. The use of potent drugs is justified only in case of mass infection and the low effectiveness of other means.

In conclusion, I would like to note that if your pepper turns yellow in a greenhouse, the reason may be either in improper care, or in the neglect of preventive measures to protect against diseases and pests. In turn, timely measures taken will help to quickly restore the health of vegetable crops and avoid crop losses.
