Why do pepper seedlings turn yellow?

Sometimes it happens that all the efforts invested in growing seedlings are not justified. It can turn yellow in just one day. Let's deal with this problem in detail. It's worth noting that sudden yellowing is primarily associated with stress.

Main reasons

Among the main causes of yellowing of seedling leaves pepper the following can be distinguished:

• The yellowing of the leaves from below with the transition to the upper leaves may be due to a lack of nitrogen. In this case, an additional feeding peppers... To do this, under each bush you can add an Azogran granule.
• Another reason is associated with poor root development or their withering away. In particular, this may be due to the fact that during the growth of the seedlings, the roots developed strongly and intertwined. As a result, the process of absorption and nutrition is disrupted, and the root system begins to die off. At the same time, when transplanting, the roots should be straightened so that the plant grows efficiently and quickly. If the plant lacks vitamin B, you can feed it.
• Also, this problem may be associated with gnawing the roots of various pests.

But if only the lower leaves turn yellow, don't worry. This is usually associated with the process of plant growth and maturation.

Soil quality

Why do pepper seedlings turn yellow? This problem is always of concern to gardeners. After all, yellowing of pepper seedlings can negatively affect the future harvest.

The problem may be related to the quality characteristics of the soil and its condition. Lack of nutrient compounds in the soil leads to malnutrition of the plant and yellowing of the leaves. This is the most common cause of seedlings yellowing. Excessive watering can lead to decay of the seedling roots, as well as disruption of the normal development and growth of plants. The low temperature of the water or soil leads to such adaptation of the pepper to the surrounding conditions.

With a lack of trace elements such as phosphorus, nitrogen, potassium, magnesium, the lower leaves suffer more often, and with a lack of iron, manganese, boron, zinc, the upper young leaves suffer.

If there is not enough nitrogen, the leaves on the plants become pale, then turn yellow at the top and die off. If there is not enough potassium, then the tissue turns yellow from the edges, and the leaves curl downward. In this case, you need to apply a complex mineral fertilizer with the addition of trace elements.

It is also necessary to adjust the watering of the seedlings, to select the optimal water temperature. Seedlings should be watered with warm water, making sure that there is no overflow. Also, the seedlings should not be constantly in direct sunlight, they must be protected and sheltered. Periodically, the seedlings need to be ventilated.

Ventilation provides fresh air. The seedlings are gradually accustomed to bright light and cool air, carrying out periodic hardening on the balcony.

Nitrogen deficiency

If a pepper seedlings turns yellow, the main reason is nitrogen deficiency. Plants, like humans, require adequate nutrition. Nitrogen is one of the most important nutrients. It affects all life processes in plants. It is found in proteins and nucleic acids. Plants need a lot of nitrogen as they absorb it intensively from the soil.

If the amount of nitrogen is limited, it begins to move from older parts of the plant to younger ones.This process can be so significant that life processes continue only in the upper part of the plant. Therefore, nitrogen must be constant to ensure the normal development of the pepper seedlings.

It is not difficult to eliminate nitrogen deficiency. To do this, simply feed the seedlings with a solution of one of the nitrogen fertilizers - ammonium nitrate or urea (carbamide). But do this very carefully, as excess nitrogen is detrimental to the seedlings.

Use only a weak solution. It is better to re-feed the plant after a few days than to overfeed it in one go.

Take a 10 liter bucket of water and add one tablespoon of fertilizer to it. This solution will not burn the leaves of the plant. Therefore, you can not only water the plant, but also spray it with this solution. This will allow for foliar feeding.

As a result, the leaves will receive prompt nitrogen delivery. But you should not rely on foliar feeding alone, since this is not enough. The plant uses up all of the supplied nitrogen immediately.

After treating the plant with top dressing, do not expect the plant to turn green immediately. Affected leaves cannot be saved. But the new leaves will grow healthy, and the plant will delight you with a good harvest of pepper.

If the leaves of your seedlings turn yellow, do not expect irreversible consequences. Eliminate the cause of this process promptly. After that, you can safely wait for a good harvest. Take care of your seedlings on time.
