Why do peppers turn yellow leaves and what to do?
Pepper is valued by children and adults for its rich taste and richness in vitamins and microelements.However, this demanding culture can create many difficulties in the process of growing. For example, it happens that the leaves of the plant may turn yellow, and then fall. Various reasons may contribute to this. What exactly and how to help the bush - let's talk in this article.
The reasons
If the bell pepper leaves turn yellow, it can happen quickly enough. A day is enough for this process, called chlorosis by scientists, to hit the plants in the garden. The danger lies in the fact that the vegetable grows poorly, sheds leaves and as a result may simply die. A number of factors can contribute to problems: lack of either excess moisture, nitrogen deficiency, exposure to toxins, or entanglement of roots. The reasons may be different in certain periods of the cultivation of sweet pepper, and also depend on the place of its landing.
At the seedling
In our country, the first stage of planting peppers is breeding seedlings. It is possible to plant a vegetable where it will grow in the future, no earlier than 1-2 months after the emergence of shoots, the exact dates depend on the variety. If the seedlings turn yellow, this becomes a problem for gardeners, who have invested a lot of time and energy in the plants. We will understand the main causes of this trouble.
Strangely enough, but in case the seedlings turned yellow before the transfer to the main site, the wrong water regime is often to blame. Despite the fact that Bulgarian pepper favorably refers to humidity, overflow can threaten the development of pathogenic bacteria in the earth, which often causes root decay. First of all, chlorosis affects the lower parts of the plant. Gentle leaves begin to brighten, soften, and eventually turn yellow. This can happen literally within 3-4 days.
In case of rapid yellowing of the seedlings, when the temperature in the room was above 15 degrees, attention should be paid to the roots. Most often this indicates damage to them. Such a problem may occur if the soil is loosely sloped.
If the soil for seedlings is purchased in the store, it is usually saturated with nutrients, which are enough to feed the plants for the entire period of being in it. If the leaves quickly strengthened and gained strength, and then began to turn yellow, this means that the supply of nitrogen in the ground is over. Also, the yellowness that comes from the bottom leaves, for those peppers that are almost ready for planting, can speak about their aging. It is not dangerous in a situation where the rest of the green has a rich color and fresh look.
When seedlings grow in a common box or in small containers, when transplanting it into open ground, yellowing of leaves from below is a common thing. Since the roots, feeling freedom, tend to grow more and more, nutrients are spent on ensuring this process. In this case, the greens for some time loses some of the nutrients and can not grow as fast. It should also be borne in mind that the conditions of the open ground are quite harsh, so the adaptation may take some time.
In the greenhouse
In a greenhouse or greenhouse, Bulgarian pepper is recommended to grow in areas with a difficult climate and capricious weather. In such conditions, if the leaves turn yellow and curl, it can talk about problems with the plant, which threatens to get a good harvest. One of the main problems is insufficiently fertilized soil. If several different crops are grown in the greenhouse, for example, tomatoes, peppers, and eggplants, and all of them have yellowing leaves, this indicates a nutrient deficiency, in particular, potassium and nitrogen.
With a lack of potassium, only the lower plates turn yellow, but near the veins their color does not change. The shoots cease to grow, and the fruits are covered with spots of yellow color. If the bottom leaves become yellow, then there is not enough nitrogen in the soil.Deficiency of phosphorus is expressed in changing the color of the leaves to violet-purple, and later - to black.
Greenhouses and greenhouses create ideal conditions for the spread of pests, for example, such as spider mites. It has a small size, and at the same time is able to thoroughly spoil the life of gardeners. Insect sucks the juice from the leaves, which leads to chlorosis. The front side is covered with small bright spots, which soon dry out, and on the back there is a layer of cobweb, which serves as a shelter for ticks.
If the greenhouse is made of glass, sunlight can be dangerous for plants. With a lack of moisture and under the scorching sun, the leaves quickly grow dull and dry.
In the open ground
The causes of chlorosis, characteristic of greenhouses and greenhouses, can be applied to seedlings planted in open ground. However, there are other factors that cause this process, even if the plants are outdoors. One of them can be called a lack of moisture. Since peppers are very fond of water, watering should be systematic and abundant. If the weather is hot and dry, the vegetable should be watered daily. However, there is another side to the coin. Overflow, although it is quite rare, also does not benefit the crops. If the weather is inclement, accompanied by frequent rains and thunderstorms, which does not allow the earth to dry out, there is a risk of rotting of the roots of this culture. It can also occur in cases where watering is done correctly, but at night the temperature drops sharply.
The love for heat of these plants does not allow them to grow and develop properly in cold weather. If the temperature drops below 12 degrees, the peppers freeze, the roots stop working, and the supply of useful elements stops, which leads to yellowing of the leaves. Iron deficiency is another cause of chlorosis in peppers in open ground. In this case, the leaves turn yellow gradually, starting from the center. If the spots are large, randomly located on the green, this means the plant lacks manganese. Yellow specks can also indicate a lack of calcium, this is a problem of many soil types, since a sufficient amount of this nutrient is only in black soil. When it is deficient, plant growth stops and leaves begin to fall.
Also a problem when landing in open ground may be the invasion of pests, for example, aphids, spider mites, wireworms or caterpillars. It can also lead to yellowing and death of the bushes.
Treatment
For each specific problem there is a solution. What to do if the leaves begin to turn yellow? The main thing - to determine how to deal with the disease.
As for seedlings, first of all you need to monitor the proper water regime. Crops are watered once every few days, the earth must have time to dry. Water should be warm, it is best to use distilled liquid that does not contain chlorine. Rain or melt water is ideal to water the peppers.
Ensuring good drainage in tanks used for seedlings is imperative. When the liquid is collected in trays, it must be drained. If the roots began to rot, you need to add special drugs, for example, "Fitosporin" or "Trichodermin." Suitable solution of potassium permanganate, diluted to a bright pink color.
The absence of rot and the presence of yellow leaves means that the plants need to be fed with nitrogen. However, the main thing here is not to overdo it, otherwise it may lead to drying out of the crops. Complex fertilizer is perfect in such cases. To improve immunity in peppers, they should be sprayed with "Epinom". This is done no earlier than one day before transplanting in a greenhouse or open ground, so the seedlings will cope better with the adaptation period.
If, in a greenhouse or in the open field, the plant was attacked by a spider mite, it is possible to use both store preparations and folk methods.If the leaves are not too strongly affected, it may be sufficient to treat with medical alcohol. They need to gently wipe the leaves. A large number of insects can be removed using a decoction of tobacco. To do this, half a kilogram of tobacco dust should be poured with 10 liters of water and left for a day, then boiled, drained, mixed with household soap, grated, and diluted with water 1: 1, and then spray the bushes with the resulting mixture.
If the peppers are sunburned while in the greenhouse, they need to be treated with Epin. With a shortage of nutrients, Agrovita addition to the soil will save the situation. This is a complex mineral fertilizer, it is produced in granules, which are buried in the garden.
As for the open ground, the water regime in this situation is also important. If the roots began to rot, you must use "Trichodermin" or "Fitosporin", the deficiency of trace elements will replenish fertilizer such as nitroammofoski, as well as the infusion of chicken manure and mullein. In cold nighttime, plants can be closed with a special material stretched over the arc. With a lack of calcium, shredded eggshells will help; she just needs to sprinkle the earth. Iron and manganese deficiency will be covered by copper sulfate and Agrovit.
Prevention
Wanting to grow a large, tasty and juicy Bulgarian pepper, you need to bear in mind that it does not adapt well during transplantation. Therefore, after leaflets have appeared on the seedlings, they are recommended to be transplanted from the common box into separate containers. So you can avoid intertwining the roots.
If the root system starts to rot, you need to consider that some plants will not be able to save. This is a very unpleasant moment, for its prevention it is necessary to avoid overflow of plants, and for irrigation only use warm water. Drip irrigation can be an excellent option. In addition, you need to monitor the maintenance of the temperature in the room. The best seedlings grow with indications on thermometers at 22-23 degrees. Cold temperature, below 12 degrees, leads to the death of crops.
To protect greenhouses and greenhouses from pests, you need to regularly monitor their condition, timely remove plant residues, which are an excellent place for breeding and wintering insects. Spraying insecticides before planting will also be superfluous. Since the ideal breeding ground for pests is dry air, it is worth maintaining a certain level of humidity, which should not be less than 60 percent. You also need to provide water for the plants themselves.
Do not water the plants with a scorching bright sun, it can cause burns. The best time for watering is morning and evening hours. Sharp temperature fluctuations are dangerous for pepper, in cold weather it should be additionally provided with complex feeding.
Gardeners tips
Yellowing the leaves of the peppers is a problem that gardeners often face. To cope with it, there are a number of recommendations.
First of all, they relate to the proper transplanting of seedlings. If the sprout is removed incorrectly, there is a risk of spoiling the root system. To eliminate this nuance, you need to get the plant out of the cup along with the soil and very carefully, after wetting the ground. In the process of planting, you need to try to straighten the roots so that they do not get tangled, and the central should go down.
It is also very important to choose the right place for the bed. Direct sunlight can damage the pepper, so it’s better if the light is slightly diffused, but it should be enough. The water used for irrigation can be heated by placing containers with it in the sun.
Due consideration should be given to airing. Stagnant humid air can cause some diseases, for example, a black leg. This unpleasant disease is fungal and can greatly harm the pepper, until its death.If the air is too dry, it is recommended to use an ozonizer, it will give a flow of oxygen.
Cotyledon leaves - the highest point to which you can drop sprouts into the ground. For additional root growth, you can pick it up.
With a shortage of nitrogen should be watered and sprayed bushes with a solution of urea or ammonium nitrate. In order not to get a chemical burn, it is necessary to prepare a fairly weak solution, at the rate of 5 liters of water per 10 grams of fertilizer. For a good potassium concentration, preference should be given to silt soil. In addition, it is useful to use boric fertilizers, which require only 20 grams per 10 liters. If the soil is highly acidic, adding humus, slaked lime, chalk and wood ash will help.
Place for planting peppers each year should be selected new. This is due to the fact that healthy trace elements are constantly drawn out by one type of culture, and they may simply not remain.
And the last. In order to harden the seedlings before planting in the ground, gardeners recommend gradually lowering the temperature in the room to 17-18 degrees. This will help strengthen the plant and shorten the time of its adaptation.
