Pepper leaves turn yellow: what to do, why they fall in the greenhouse, open ground and windowsill

When pepper leaves turn yellow, you need to know why. Only in this case it is possible to correct the situation and save the crop. There could be many reasons.

The most common are improper care, disease or pest invasion.

Reasons for color change

There are several reasons why the leaves of peppers planted in the garden plot turn yellow.

1. Wrong watering. In bell pepper, the root system is very delicate and vulnerable, so the plant reacts strongly to the lack of moisture or vice versa, excessive watering.Wet soil leads to rotting first of the roots, then of the upper part. Lack of moisture causes the leaves to dry out.
2. Watering with unsettled, cold water stops the development of the plant. If the water for irrigation is regularly cold, real leaf fall is observed.
3. Sharp temperature fluctuations. The leaves turn yellow, both from the cold and from direct sunlight. This is especially true for young seedlings. Therefore, you need to take care of shading on a hot day and covering during frosts.
4. For pepper, you need to choose the right place on the site in the open field. You can not plant where tomatoes, potatoes, eggplants used to grow. Residual roots of these plants begin to secrete substances that harm the development of pepper. In place of nightshade vegetables should be planted no earlier than three years later. Otherwise, the pepper sheds leaves and decreases disease resistance.
5. Nutritional deficiency. First of all, the lack of nitrogen affects the condition.First, the upper leaves lighten, and then begin to turn yellow from the middle. The fruits at the same time have thin walls and are twisted. If the lower leaves turn yellow, there may be a lack of potassium. At the same time, the tips of the leaves dry, the trunk changes color, becomes hard, spots appear on the fruits. With a zinc deficiency, yellow-green spots can be found on greenery. You can correct the situation or prevent problems completely with timely top dressing.
6. Pepper leaves fall off and change color due to insects. All vegetable growers face pests. Most often, pepper is attacked by a spider mite. It feeds on the juice of the foliage, from which yellowing and drying begins. Soon, if no action is taken, the edges of the leaves will begin to dry, and then not only they, but also the fruits may fall off altogether. Any insecticide helps against pests, for example, Fitoverm, Aktara, or a self-made solution based on wood ash, bird droppings, green grass and other components.
7. It happens that pepper leaves turn yellow from diseases and what to do in this case, you must know.If the plant is affected by a virus, the leaves begin to turn yellow and dry, the fruits are bent. To save the entire garden, it is necessary to urgently remove the infected plant, and treat the soil with a disinfectant solution, for example, with potassium permanganate.
8. Yellowing foliage results from lack of sunlight. Often the problem appears when the bushes are planted in a shaded area.

It is important for preventive purposes to treat the plant from pests and diseases, fertilize at least three times during the entire growing season, prevent weeds in the garden and recognize in time why the pepper leaves turned yellow so as not to ruin the entire crop.

Sometimes a yellow leaf at the bottom of the stem appears as a result of the maturation and growth of the vegetable. At the same time, all other parts of the bush look good.

The problem with young seedlings in the greenhouse

It is recommended to grow seedlings of peppers in a greenhouse. First, the soil must be dug up, weeds removed, treated for pests and organic or mineral top dressing applied.

Many vegetable growers are concerned about the problem of why the foliage of sweet peppers turns yellow even in favorable greenhouse conditions? To understand what is happening with the plant, you need to follow its growth and development at each stage.

Pepper seedlings cannot be protected from various misfortunes, even, it would seem, in such a protected place as a greenhouse. There are several reasons why the leaves of the seedlings turn yellow and eventually fall off completely.

• Irregular watering can be the cause of falling leaves in a greenhouse plant. It is not recommended to allow the soil to dry out. During a drought, the seedlings wither, and a yellowish tint appears on the green. Young seedlings are recommended to be watered every five days with settled water.
• Harmful and too frequent soil moisture. With an excess of moisture, the lower leaves fall off the seedlings.
• Lack of nitrogen, potassium or phosphorus in the soil.
• The air temperature in the greenhouse should not fall below 14 degrees. Otherwise, the soil freezes, and the lower leaves of the pepper seedlings turn yellow. If the temperature does not return to normal, then the whole plant dies.
• Peppers react to lower air humidity levels. A humidity level of 70% is considered normal.
• Inadequate light supply causes the leaves to dry and fall off. A month after planting the seeds, seedlings need to be provided with additional lighting.
• Why seedlings have leaves in poor condition also depends on the distance at which the seeds are sown. If the seedlings are nearby, then the roots and leaves begin to interfere with each other, intertwine. As a result, the stems are stretched and the foliage turns yellow.
• The plant can shed its leaves due to the vigorous activity of insect pests. If pests are the cause, they can be easily noticed. The most common are aphids, thrips, spider mites.
• When a pepper turns yellow and even leaves fall, it is often a fungal, viral or bacterial disease.

Proper seedling care begins with the selection of seeds for planting. You need to choose only large and dense grains. Then they must be kept for some time in a solution of potassium permanganate so that no bacteria remain on the shell of the seeds.

The first fertilizer for seedlings should be done when two leaves appear. Then you need to wait for the unfolding of 6 leaves. As an organic top dressing, an infusion of manure or bird droppings is suitable. You can not add fresh manure to the soil, as this can lead to a burn of the root system of the plant. Potash-phosphate elements are needed from mineral fertilizers.

Growing seedlings at home

When seedlings are grown at home, on the windowsill, then here you can not protect yourself from problems. If pepper seedlings turn yellow, you need to deal with the cause in time in order to get a rich harvest in the future.

Why does the color and condition of seedlings change? If the leaves of all pepper seedlings turn yellow, you need to calculate the root cause to help restore the plant.

1. Seedlings turn yellow due to a weak root system. In young shoots, the roots are the weakest part, it is their damage or strong growth that causes yellowness. The roots begin to tangle and intertwine, nutrients are poorly distributed, and the roots die off. The roots can also be damaged during deep loosening. It is recommended to carefully dig the plant out of the container and check the roots. If there are few root branches and they have darkened, the plant dies. If the roots are intertwined, but the whites need to be carefully straightened.
2. When everything is in order with the root system, the reason may be due to a nitrogen deficiency. It is recommended to apply nitrogen-containing fertilizers, you can use urea or ammonium nitrate.But do not overdo it. Since an excess of nitrogen also affects the condition of the plant. Fertilizers should be applied at intervals of two weeks.
3. Sometimes the answer to the question of why the leaves fall and turn yellow is associated with a decrease in the air temperature in the room. Young seedlings do not tolerate temperatures below 14 degrees. The box with seedlings should not be placed in a draft.
4. The cause of leaf fall may be related to improper dosing of water. Newly planted seedlings are watered once every 5 days, as soon as the sprouts gain strength, watering is increased to every three days. Do not neglect these rules, as an excess or lack of moisture can cause the pepper leaves to turn yellow and fall off.
5. Insufficient light can cause leaves to turn white and stems to stretch. Therefore, seedlings are best placed on the windowsill of the south window. On short or cloudy daylight hours, additional lighting should be provided.

Seedlings need to be transplanted to a permanent place in time. If it outgrows, then the roots will be large and in a new free place they will begin to diverge even more to the sides. All nutrients and forces will go to their development, and not to the upper part. As a result, the pepper does not grow, and the leaves dry up.
