Garlic turns yellow - how to feed and how to process. What to do if garlic turns yellow in spring and why this happens Feeding garlic in early spring

Garlic is a popular vegetable for planting in gardens and orchards, because it contains a huge amount of useful substances, thanks to which garlic is used as a medicine. Also, garlic gives food an amazing taste and aroma, so it is not surprising that many people like to plant it in vegetable gardens.

Gardeners planting garlic in their area may always be faced with the question: “Why does garlic turn yellow in spring and what to do?”. The yellowing of the garlic starts at the tips, then quickly increases, which leads to a slowdown in the growth and development of the plant, to a not the best harvest.

In this article we will try to help gardeners find the most effective solutions to avoid such problems. Below we will look at the reasons why garlic leaves turn yellow, and describe methods to combat yellowing.

There are two types of garlic: spring, considered spring, and winter or winter. Most of all, the leaves of a winter plant undergo yellowing even during spring frosts.

In general, yellowing of garlic can occur due to various reasons:

If garlic is planted very early before winter, then it can give green shoots by autumn, which will then be seized by frost, from which the leaves will turn yellow by spring. gardeners middle lane countries should plant garlic no earlier than October 15-20, in the south in mid-November.
Due to unfavorable weather conditions, frosts.
Garlic May Be Lacking Health Benefits nutrients.
With insufficient watering or its overabundance. If the air-water balance is disturbed, the culture will be spoiled. Do not forget: it is much easier for a garlic plant to survive a drought than an excess of moisture. Watering a garlic plant should be carried out according to the following scheme: with precipitation in a small amount, the plant is watered once within fourteen days; with constant precipitation, you should not water the garlic at all; in the absence of rain, watering should be increased to once a week.
With a lack of nitrogen in the soil. With constant precipitation, fertilizers begin to wash out of the soil, after which nitrogen starvation begins in the garlic plant. In order to prevent nitrogen starvation in garlic in the fall, ammonium sulfate is used by gardeners, in early spring minerals and organic matter. It can be liquid manure or carbide. It is most effective to mix 20 grams of substances in a bucket of water, then water the plants. Only in this way will the substances quickly flow directly to the garlic.
With a lack of potassium or magnesium in the composition of the soil. If the garlic plant does not have enough potassium, then the roots will be damaged, yellowing, drying and wilting of the leaves will begin, the garlic will stop growing. When fertilized with potassium, the growth of the garlic plant will be stimulated, the resistance of garlic to frost, pests and dry weather will be increased. O not enough potassium is also notified by other signs, such as: uneven growth of leaflets that droop and grow thin, and “marginal burns” begin to appear on the edges of the leaves along the edges of the leaves. With a lack of potassium in the soil, garlic can be fertilized with wood ash, per meter of plot 100 grams of ash. Ash is also considered an excellent phosphate fertilizer.
If the planting depth of the teeth is more than 7 centimeters. It is best to plant garlic at a depth of 5 to 7 centimeters. With a deeper planting, the vegetable freezes and the leaves turn yellow. To avoid yellowing of the leaves, it is necessary to cover the young sprouts with a film of polyethylene. However, if garlic is already affected by spring frosts, then the vegetable must be treated with special stimulating drugs. The sooner gardeners start processing during frosts, the better. "Zircon" and biostimulant "Epin" help to improve root formation and flowering, increase resistance to diseases. 8 drops of "Zircon" per liter of water, then garlic cloves are soaked for 60 minutes. 1 milliliter of "Epin" is dissolved in a bucket with five liters of water.
If the soil where the garlic is planted is acidic. Only neutral soil, which is enriched with oxygen and has a sufficient amount of moisture, will contribute to obtaining good harvest. Worse in acidic soil appearance garlic plant. Reduce the acidity of the soil should be in the fall, preparing limestone, which mixes well with the soil. For soil with strong acidity, from 50 to 70 kilograms of lime are prepared; when working with medium acid soil, from 35 to 45 kilograms of lime is taken; if the soil has a weak acidity, then 30-35 kilograms of lime will suffice.
Planting garlic in frost-bitten soil or in extreme cold.

Diseases and pests

What else to water so that it does not turn yellow?

Garlic plants are watered in the spring with the following solutions:

Dilute humus or nitrogenous fertilizers in water.
During frost, growth stimulants "Epin" (1 milliliter per five-liter bucket) and "Zircon" (8 drops are dissolved in a liter bucket) are diluted in water.
Against pests, water the garlic with a solution of three tablespoons of table salt dissolved in a bucket of water.
A kilogram of wood ash is infused in a bucket of boiled hot water for three days, then mix and begin to water the beds as top dressing.
Potassium permanganate is dissolved in water, water of a slightly pink hue will help destroy harmful organisms.
Water the beds with a solution of urea (30 grams is dissolved in a 10 liter bucket) as a dry fertilizer.
1 teaspoon of potassium sulfate in a liter bucket of water as an anti-yellowing fertilizer.

In the spring, on the site, many summer residents with annoyance find yellowed leaves of garlic planting. And this is not only an unpleasant effect, but also a sign that the agricultural technology of growing winter crops has been violated. Indeed, following the yellowing of the leaves, the plant stops its growth altogether, and the cloves rot. Why does it turn yellow winter spring and what to do, we will consider in this article.

Low temperature in spring

First of all, the foliage of winter garlic turns yellow in spring due to low temperatures. And this is the main reason.

Snow no longer covers the plant, and it becomes vulnerable - the roots weaken, and the energy for development is taken from the leaves.
Basically, deep planting leads to freezing of garlic. Therefore, in order to avoid the appearance of yellow leaves, it is desirable to plant this crop at a depth 5-7 cm. And you can prevent the appearance of yellowness in the spring by covering young seedlings with a film.

If garlic plantings are slightly frost-bitten (there was a frost), they should be immediately treated with solutions of HB-101, and others. They will not only improve root formation, but also make the plant more resistant to various.

Did you know? You can avoid freezing winter garlic by proper fit in autumn - 10-20 days before the onset of frost.

Low acid soil for growing

In order for garlic to please with its harvest, it should be planted in neutral. If the soil in your area is highly acidic, it needs to be lowered. To do this, during autumn digging, add to the soil lime.
At hyperacidity the norm of lime per hundred square meters is 50-70 kg, for sour ones - 35-45 kg, for slightly acid ones - 30-35 kg. After lime has been applied, the area must be carefully dug up.

nitrogen deficiency

Lack of some nutrients, including, is also the cause of yellowing of the foliage and the appearance of a reddish tint.
If you notice that the tips of the leaves turn yellow in winter garlic, the first thing to do is to urgently fertilize the soil with manure or carbamide (). At the same time, urea is recommended to water the plant directly over the leaves.

Important! Fertilizers applied in autumn are washed out of the soil during the winter.

Insufficient watering of the plant

Garlic plantings love moisture, so the soil should be loose and well moistened - so it is enriched with oxygen.

Watering is especially relevant at the beginning.
It would be nice to use highly effective additives that help loosen the earth and structure it, increasing the degree of absorption of moisture and nutrients.

Important! Excess moisture for garlic is more detrimental than its lack.

Potassium deficiency

Potassium deficiency can also harm a young plant. In most cases, yellowing of the leaves for this reason is observed in the cold spring.
The roots in this case do not receive sufficient nutrition from the soil and begin to take potassium from the leaves. Potassium deficiency can also be determined by the uneven growth of the leaves, they droop and become thin.

At such a time, you need to know how to water the garlic if it turns yellow due to a lack of potassium. It can be any , or simple .

Did you know? Well compensates for the lack of potassium ash solution - a glass of wood ash and 2 tablespoons of salt in a bucket of water.

Diseases of winter garlic and yellowing of leaves

The most common diseases accompanied by yellowing of garlic leaves are are:

white rot. The leaves of the plant first turn yellow and wither, the bulbs become moldy and rot. Plants die one after another, and a fluffy whitish coating is visible on their surface. Most often, the disease occurs in the spring, with a nitrogen deficiency.
basal rot. Although this type of fungus is present in almost all soils and does not cause any particular problems if the plants do not experience stress. Manifested by yellowing of the leaves, which moves down. In principle, the symptoms do not differ from white rot, only the plant rots more slowly. You need to deal with this trouble in advance by treating the planting material with a disinfectant solution (for example, Tiram).
Aspergillosis or black mold. The most, perhaps, dangerous disease, which most often affects an immature plant. Symptoms - the bulbs become soft, the leaves turn yellow.
Fusarium. The source of this disease is excess moisture. The leaves begin to turn yellow on top already in the process of ripening. This disease is characterized by brown stripes on the stems. If it turns yellow due to fusarium winter garlic, the first thing to treat the plant is a solution potassium permanganate.
Penicillosis or blue mold . It mainly affects the plant after harvest as a result of inaccurate handling. Garlic gradually turns yellow and dies.
Rust. Loves high humidity. It appears as yellowish spots and specks on the leaves. Over time, the foliage turns orange and brown. Fight method- treatment of cloves before planting.

Garlic often turns yellow from fungal diseases. Of course, fusarium and bacterial rot It's easier to prevent than to treat.

Therefore, before planting, it is advisable to disinfect the cloves of the plant with a weak solution of potassium permanganate or Maxim preparations and pour the planting material with the solution for 15-30 minutes. Even if you did not do this before planting, you can already water the beds with a solution.

For prevention, you can also disinfect the soil by treating it with a solution (copper sulfate) or saline. When the first signs of damage to the plant appear, it is urgently necessary to process the garlic plantings

Garlic is a fairly common agricultural crop among domestic gardeners. It is cultivated in various climatic zones, as the plant is not particularly picky. But the main advantage of growing garlic is the huge benefits that it brings to human health. As part of this home plant contains trace elements, vitamins C, E, essential oil, as well as phytoncides. In general, garlic has strong anti-inflammatory properties, so everyone should include it in their daily diet. How to grow it, and what to do if the garlic turns yellow in spring?

Possible causes of yellowing

Many novice farmers may wonder why the garlic turns yellow in the garden? A similar situation is not uncommon in our time, so you need to know how to fix the situation and what measures to take so that in the future such a problem does not befall you. At first glance, the yellow stalks of garlic are nothing to worry about. However, if you sit idle for a long time, the garlic cloves will begin to actively rot. Why does homemade garlic turn yellow?

There may be several reasons. Among the most likely are:

overdried soil or, conversely, overly moistened. Sometimes gardeners do not pay too much attention to this moment, but meanwhile, controlling the level of humidity in open field is of great importance for the growth and development of garlic. If seedlings this plant do not water at all or do it too often and in large volumes, the stems of the crop may turn yellow;
small amounts of nutrients. Farmers do not always apply fertilizers to the soil in a timely manner and in sufficient quantities. If this factor is not taken seriously, the plant will develop incompletely, and yellowness in this case is no exception to the rule;
illiterately selected type of soil. There are times when gardeners do not think at all about what kind of soil garlic seeds should be determined in. In the meantime, this is important. Experts recommend buying varieties that can take root and develop normally in the earthen substrate in your area;
if winter garlic grows in your garden plot, and for the winter it turned out to be without shelter (the shoots of this plant did not cover the snow, and you did not take care of the presence of some kind of oilcloth), low temperatures in winter period will not have a very beneficial effect on the integrity of agriculture. Hence the yellowness of the stems;
disease or pest infestation. No one is immune from this, however, with regular inspection of garlic seedlings, this problem can be eliminated in the early stages.

What to do if yellowed garlic grows on your suburban area? There are a few key rules to follow. For example, try to introduce into the soil nitrogen fertilizers. With their lack, the soil becomes acidic, which is quite painful for homemade garlic. How else can you reduce the level of acidity? The best option- Feeding the soil with limestone or ash.

Sometimes the reason for the yellowing of garlic is quite commonplace: a hard top layer of soil. The thing is that if the soil is not loosened from time to time, it will lack air-gas exchange. In the end, the plants simply stop breathing, the substrate becomes clogged, and yellowness appears on the stems of the agricultural crop. Make another important attempt to prevent garlic yellowing: keep your plants well watered starting in June. If the soil is too dry, this is fraught with serious consequences.

To prevent homemade garlic from turning yellow, be sure to exclude fresh manure from the entire fertilizer complex. The thing is that due to its presence in the soil, the risk of diseases and pest invasion increases. By adhering to these simple rules, you will forever get rid of yellowness on the plant.

Folk methods of dealing with yellow leaves

How to feed the culture

If the garlic turns yellow, it is quite possible that the reason lies in the lack of nutrients on garden plot. In most cases, the problem of yellowness indicates a deficiency of potassium and nitrogen. Another component that is often present in the soil in small quantities is magnesium. Therefore, every farmer needs to be able to fill this gap. At the same time, it is necessary to distribute the stages of feeding in such a way as to alternate mineral and organic fertilizers. There are several methods of feeding the soil in which spring or winter garlic is cultivated:

nutrient mixtures in granules are scattered into special holes that need to be formed in the aisle. Use carbamide or a complex solution. After top dressing, the holes are covered with earth, and then watered without fail. Thus, the fertilizer will quickly dissolve in the ground. At the end of this procedure, you can also mulch the soil. If you fill the holes with compost, moisture will be retained in the soil longer than usual;
foliar top dressing is another common way. For this purpose, potassium sulfate or mineral components are mainly used. The nutrient mixture must be poured into the sprayer, and then young shoots can be sprayed. Try to follow another key recommendation - spray the solution with fertilizers on the leaves only in dry and calm weather. Only in this case, most of the mixture will fall on the plants, and they will be able to more actively saturate with useful substances.

Sometimes farmers prefer organic mixtures. An infusion of cut grass with the addition of wood ash is considered to be in demand. Provide regular fertilization of garlic seedlings - and the result will exceed all your expectations.

Proper Care

Garlic began to turn yellow, what to do in this case? Many beginner gardeners puzzle over this. However, if you follow the basic recommendations for caring for winter or spring garlic, there should be no problems with the yellowness of the plant stems. If you want your homemade vegetable to become an essential part of any gourmet meal, you'll need to put in some work on your garlic sprouts.

Not only timely top dressing of the soil and watering is important here. It is also necessary to provide full coverage of seedlings of agriculture. This aspect needs to be paid attention to even in the process of planting garlic. If the plants can still do without regular watering, then natural light there should be plenty.

How to eradicate a similar problem at an early stage of infection of agriculture? It is recommended to frequently inspect the seedlings of garlic. If you notice the presence of a small number of insects near the plants, you need to act immediately. Make every effort to ensure proper care for homemade garlic seedlings - and you will provide yourself and your loved ones with vitamins and versatile spices for the whole year.
