Why does winter garlic turn yellow in spring: what to do? When to plant garlic on a head in the spring and how to feed garlic planted before winter? Is the garlic turning yellow? Causes and methods of control Garlic turns yellow, how to save it - folk methods and more

Why does garlic turn yellow in the spring, what to do about this problem?

This question plagues many gardeners who are faced with yellowing of the leaf blades of winter garlic with the onset of the spring season.

And this is not surprising, because garlic is an indispensable part of the diet of many people.

This is due to what it contains large number useful microelements, vitamins C and E, as well as phytoncides that have an antimicrobial effect.

Is folk remedy against various diseases. In addition, it helps to activate metabolic processes and prevents the development of diseases such as atherosclerosis and other equally serious pathologies.

Therefore, lovers of garlic spices try to grow it on their land plots, especially since it does not require special care.

But even such a resistant plant can get sick, begin to dry out, turn yellow and even die. Let's take a closer look at the reasons for the yellowing of young shoots of garlic and ways to solve the problem.

Reasons

If in April-May the feathers of garlic begin to acquire a yellow color, this may indicate violations of agrotechnical rules.

The result of this may be the cessation of growth activity and the beginning of the processes of rotting of the planted cloves.

The main reasons for spring yellowing of leaves are:

  • insufficient or, conversely, excessive level of soil moisture;
  • nutritional deficiencies;
  • acidic soil structures;
  • consequences of prolonged winter low temperatures;
  • consequences of late spring frosts;
  • pests and diseases.

In order to promptly protect the garlic crop from the effects of the above factors, it is necessary to follow the basic agrotechnical rules for growing winter crops.

This means that the solution to the problem, and in some cases prevention, is the following:

Please note: It is recommended to start watering the beds where garlic grows in June. The most important thing is to not allow the soil where the garlic is planted to dry out, and watering should be moderately abundant.

To receive good harvest, you need to create everything favorable conditions so that the plant grows well and does not begin to turn yellow with the arrival of the spring season.

What to do

You can save the harvest by doing the following:

  1. Apply complex fertilizer.
  2. Enrich soil structures with potassium sulfate. A solution of potassium sulfate is suitable for spraying the stems.
  3. Water all beds with garlic with diluted table salt, special pest control agents, or a pale pink solution of potassium permanganate (potassium permanganate).
  4. Compacted soil crusts on the beds must be loosened.

Such integrated approach will help you cope with the problem that has arisen.

To prevent this problem from occurring next year, it is recommended to properly prepare the material for planting, as well as add the necessary fertilizers to the soil.

Gardener's advice: Do not use fresh mullein or manure as fertilizer, as it is the main cause of various pathologies.

Pests and diseases

As already mentioned, garlic is also exposed to the pathogenic effects of various pests and diseases, among which the most common are:

This disease is mainly localized on the leaf blades of garlic or onion. It is characterized by the appearance of pale spots of a light green shade of a vague nature on the leaf blades. As a result of the development of the disease, a gray coating forms, which is the reason why garlic turns yellow. From the affected leaf, infectious cells penetrate into the head, where they remain until the next spring season.

Please note: In order to preserve the heads of garlic affected by downy mildew and to eliminate the infectious cells of peronosporosis, it is necessary to warm up all the heads before storing them.

This is a dangerous fungal disease that occurs as a result of sudden temperature changes. Basically, the disease affects all types of garlic, as well as the most popular varieties of onions - sets and selections. Mold forms on the surface of the upper layers of scales, which leads to softening of the bulbs and further penetration of mold.

Please note: The most susceptible to the formation of black mold are unripe and undried heads of garlic.

This disease occurs due to excess moisture and nutrient deficiency. The first signs of the development of this disease are early yellowing of the tips of leaf blades and their rapid death. In the bottom region of the head of garlic, the presence of pink, yellow and white coating. This disease has the character of rapid infection of healthy fruit crops.

  1. Emergence onion fly.

This insect, when settling on leaf blades, begins to actively eat them, which is a consequence of yellowing of the leaves. In order to secure vegetable crop from flies, it is necessary to disinfect the garlic cloves before planting by placing them in hot water(40 degrees) for a couple of hours.

  1. There may also be the development of penicillosis, white rot, green mold and yellow dwarfism.

Preventive measures

In order to protect vegetable crops from diseases and various pests, it is necessary to annually comply with agrotechnical rules for the preparation of soil and seeds, as well as the principles of organizing proper crop rotation.

Annual fertilization of soil structures will contribute to optimal saturation of plants with nutrients and a good healthy harvest. You can fertilize before planting and after germination, in the form of fertilizing during watering.

Yellowing of leaf blades is an unpleasant factor, but the problem can be solved in a timely manner measures taken will not keep you waiting.

Garlic turns yellow in the spring, what to do - how to quickly save the future harvest?

Gardeners often encounter this problem: garlic turns yellow in the spring. What to do in such cases, how to save the plants. It’s a shame when you grow, take care, and then in an instant the entire crop dies. To protect garlic plantings from yellowing and restore a healthy appearance, you first need to find out the reasons, only then begin to eliminate them.

Let's find out the reasons why the feather turns yellow

Let's figure out what the true reason for the yellowing of garlic is, because this is the only way to take action to eliminate it. Experienced agronomists identify several sources why the tips turn yellow:

  • too early planting before winter. It is necessary to plant no earlier than October 15, so that winter garlic does not have time to hatch;
  • With the onset of spring days, including May, frosts cannot be ruled out. Therefore, a slight frost could well have left the yellowness;
  • shortage nutrients may cause the tops to turn yellow;
  • putrefactive diseases accompanied by yellowing of foliage;
  • The culprit may also be, causing great damage to the crop.

How can you accurately determine what caused the yellowing? If you are not sure that frost is the problem, the solution would be to pull out one diseased plant from the garden and inspect it. Putrefactive diseases can be noticed immediately by the presence brown spots, darkening, even slight mold.

An example of how garlic turns yellow in spring - in the photo

If an onion fly has infested and laid larvae, go to the bed and move your hand over the feathers. The insects will immediately begin to circle. When no pests are found, no diseases are present, all that remains is to think that there are not enough nutrients. Indeed, this happens: with the melting of snow, many nutrients are washed away, most go deep into the soil, where the roots cannot reach them.

In addition, when low temperatures the plant's ability to absorb necessary nutrition from the soil is greatly slowed down. Therefore, when it is cold spring, many summer residents observe a yellow picture in the beds.

Garlic turns yellow, how to save it - folk methods and more

Depending on the identified factors, yellowing will be eliminated. Early spring As soon as green feathers appear, cover the bed with film, spunbond or other material. Be sure to apply growth-stimulating drugs (, etc.). When the threat of frost passes, remove the protective cover, you will see that the vegetable is green and feels great. Now you can feed it.

If the feathers are quite grown and have a yellow color, apply fertilizer. carried out in accordance with the schedule and condition of the plants. Now at this stage it is necessary to take urgent measures and do the following:

  • it is necessary to feed the crop. Dry fertilizer can be distributed into the furrows between the rows, then covered with soil and poured well so that all the granules dissolve. But it is better to prepare a urea solution (25-30 g/10 l);
  • after freezing, spray the plantings to remove yellowed leaves (1 ml/10 l). The drug is a powerful antidepressant for crops, which will help them recover faster and begin to grow actively. You should spray every 5-7 days until the feathers are restored to green;
  • if the vegetable is green and appearance quite satisfied with the owners, in order to avoid yellowing, it is recommended to carry out foliar spraying with potassium sulfate (1 tsp/1 l) in dry, windless weather in the evening. This fertilizer can be replaced with any complex fertilizer, the main thing is to dilute it according to the instructions on the package.

The onion fly really doesn't like carrots planted nearby, the smell repels them. If you don’t know, in the garden, the first rule is to observe crop rotation, plant savior plants nearby.

As a drastic measure, some summer residents and gardeners use salt against onion flies. Make a solution (200 g/10 l) and water the bed, then be sure to water it with regular water. clean water. Salty water is not to the taste of the onion fly or its larvae. One procedure will be enough for the season.

In June, ash and tobacco dust will come to the rescue. Just sprinkle the row spaces with a mixture of ash and tobacco dust, and you will soon notice how the pest will disappear from the beds. Ammonia will repel the onion fly and will nitrogen fertilizer, you just need to dilute it correctly (55-60ml/10l). In addition, it will save plantings.

If you find rotten spots on the bulbs, then you need to take care of healthy planting material, do not forget to disinfect the soil by spilling the garden bed with a pink solution of potassium permanganate. Immediately before planting, the cloves must be disinfected using the same manganese or saline solution, the drug Maxim. Now, dear readers, you know what to do when the garlic in the garden turns yellow.

Diseases and pests of garlic. Garlic turns yellow - video

Garlic is one of the most favorite crops among gardeners. Already in early March, its shoots delight the eye and become a harbinger of spring. However, the summer resident’s joy may give way to anxiety. Very often, when you go out into the garden, you can observe how the juicy, green leaves of garlic have turned into a yellowing feather. What to do if this problem occurs to a vegetable?

Why does garlic turn yellow in the garden? What should I do to get a high yield?

Lack of nutrition is one of the reasons for yellowing of garlic leaves

Causes of yellowing of garlic. Troubleshooting this issue

In many areas, in the spring, yellowing of garlic leaves can be observed. To combat this problem, you need to know the causes of yellowness. And only after this carry out agrotechnical measures. So why does garlic turn yellow in the spring?

Yellowing of the crop may be due to early boarding. Vegetables should be planted at a certain time; this factor is very important for plant growth. Gardeners living in the middle zone of the country should plant garlic no earlier than the twentieth of October, but for the south the optimal time will be mid-November.

Early planting can result in green shoots as early as fall. As a result, the leaves will be caught by frost, which will lead to yellow feathers in the spring.

Mulching the beds after planting in the fall is mandatory.

To prevent severe frosts from damaging the crop, it must be covered with a thick layer of mulch at the time of planting. If, however, mulching has not been done, then treat the plant with any biological preparations.

Lack of moisture causes yellowing and curling of leaves

The second reason for yellow garlic leaves may be a lack or excess of moisture. Violation of the air-water balance leads to damage to the crop. What to do in this situation? If there is little precipitation in the spring, the plant is watered once every fourteen days. If spring is hot and dry, then water the vegetable once every seven days. During rainy seasons, you should forget about watering the plant.

Every summer resident should remember important rule: Garlic tolerates drought more easily than moisture.

Yellowing of the crop can be caused by various diseases or pests. Despite the fact that garlic very often repels pests from other plants, it still has its own ailments. Damage to a vegetable may be associated with false scourge powdery mildew, rot, rust, mold, onion fly or mite. What to do?

Onion fly larvae attack the stem from the inside

Determining the presence of a pest or disease is not difficult. It is necessary to dig up a head of garlic with yellow tips and look for the presence of rot, mold, rotting of the root system, larvae in the area of ​​the bulb, or a pinkish coating.

Garlic pest - rattle beetle

What to do to prevent the defeat of culture?

Never plant garlic in the same area for several years. Before planting, make a weak solution of manganese, where the crop cloves should remain for at least twelve hours. Update every five years planting material.

Plant mint or calendula next to the garlic. The roots of these plants contain a small percentage of toxic substances and can protect the crop from a host of diseases.

White head rot causes death of roots and leaves

If the above reasons are not identified, and the garlic is susceptible to yellowing, then it lacks nutrients. In this situation, additional feeding will be needed. Garlic is not a demanding crop, so one feeding in the spring will be enough. It is produced when the ground has completely thawed from snow. How to treat a plant?

  • Place 20 liters of ordinary water in a container, add 12 grams of ammonium nitrate, 20 grams of superphosphate, 12 grams of potassium.
  • Water at a certain time winter garlic from the proportion of 20 liters of liquid per 2 square meters. meters.
  • If there is a need for secondary processing, perform it after 30 days.

Many summer residents are opponents mineral fertilizers. What to do in this situation? Solving the problem is not difficult. The plant can be watered with herbal infusion.

Root rot - the plant dies completely

What to do if yellowness has already affected the crop? Initially, fertilize, then water the plant with complex fertilizer, and after seven days feed the roots of the vegetable.

Watering with herbal infusion will give plants nutrients

It is important to know: yellow leaves of a feather do not always indicate illness. Sometimes this may be due to the onion beginning to form. During this period, all the nutrients of the leaf are transferred to future cloves.

Traditional methods of dealing with yellow garlic leaves

To combat pests and diseases that cause yellow garlic feathers, many gardeners use traditional methods protection:

Plant nearby plants that have a strong, spicy aroma (thyme, coriander).

The question arises: what vegetable should I plant next to garlic? The answer is clear - carrots! In spring, these plants will be able to protect each other from all misfortunes.

Fungal infection under the husk is the cause of yellowing leaves

Insects will not be terrible for the crop if everyone square meter fertilize the land with one matchbox urea or saltpeter. After completing the procedure, water the soil generously.

Have you noticed the offspring of the onion fly? Use carbon-ammonium salt! When you carry out preventive maintenance on the beds, treat the soil with boiling water (three days before planting the crop).

Is the garlic turning yellow? Use the information provided above and this problem will disappear!

Having learned and determined possible reasons yellowing of garlic, each gardener will be able to choose methods of processing and feeding the plant independently. It is very important to use watering and fertilizing in combination and in a timely manner. Then your garden beds will be adorned with green, lush and healthy garlic stalks!

Often the feathers of garlic that has begun to grow turn yellow. If measures are not taken in time, there will not be a good harvest.

The leaves can turn yellow on any garlic, no matter whether it is spring or winter. It’s bad when garlic turns yellow in the spring or at the height of summer, but by the time of harvesting, yellowing and drying out of the tops is normal. What to do if the garlic begins to turn yellow at the wrong time and how to treat it will be discussed below.

Reasons

Typically, yellowing - chlorosis - begins at the ends. Gradually the yellow color spreads and development is delayed. As a result, the heads will grow small.

There are several reasons for this phenomenon:

  • damage by diseases and pests;
  • lack of macro- or microelements;
  • improper water regime;
  • cold weather.

You can determine what caused the yellowing in different ways.

Garlic planted last season turns yellow

When winter garlic turns yellow in early spring, it means that the plants have been frozen.

Garlic turns yellow in warm weather

Remove a few heads and look at the roots. If they are nibbled or the bottom is covered with mold, then the reasons for the poor condition of the plantings are diseases and pests.

Yellowing is caused by two diseases to which lilies are susceptible: fusarium and bacterial rot.

Fusarium

Fusarium or bottom rot manifests itself in that the tips of the garlic turn yellow, the leaves and stem dry out quickly, starting from the end. A pinkish coating appears in the sinuses, then the aerial part becomes covered with brown stripes. If you dig up an onion, you will immediately notice that its roots have almost disappeared, and the bottom has become soft and watery.

The disease is common in southern climates, but gardeners also middle zone in hot years they encounter it. Crop losses due to fusarium can reach 70%.

Bacterial rot

Bacterial rot affects bulb crops. The disease manifests itself as brown dots on the surface of the teeth. Subsequently, the heads take on a “frozen” appearance and smell unpleasant. The garlic feathers turn yellow, then the leaves and arrows dry out and die, starting from the ends.

The sources of the disease are bacteria living in the soil. Microorganisms penetrate the plant through damage caused by mites, nematodes, etc.

Nematode

Stem nematode is a microscopic pest that lives in the soil. The plant affected by the nematode brightens, the garlic leaves turn yellow, then the feathers curl and the bulb rots.

How to recognize a nematode: looking at the roots through a magnifying glass, you can see small worms no more than a millimeter long. Without a magnifying glass, they look like a pinkish coating on the surface of the bottom.

What's wrong with garlic?

Sometimes garlic in the garden turns yellow due to lack of nutrition. More often, the vegetable experiences a deficiency of nitrogen and potassium. The situation can be corrected by feeding.

Garlic responds well to mulching with humus. You can even use chicken droppings, but it must sit in a pile for at least 2 years.

Mulching with organic matter is an excellent way to feed. If garlic turns yellow in beds filled with humus, then the cause of chlorosis is not a nutritional deficiency, but something else.

Those who prefer to fertilize their garden with mineral water can use urea and potassium sulfate to prevent yellowing of garlic leaves. The latter fertilizer also contains sulfur, which is useful for garlic.

You can carry out foliar feeding. The procedure is useful if the leaves of young plants have turned yellow. Urea or potassium sulfate is diluted in a concentration of a teaspoon per liter of water. The leaves are sprayed with a fine spray. Droplets of the working solution that fall on the leaf blades will be absorbed and the yellowness will disappear.

All onions love fertilizing, as it contains a lot of potassium, which promotes the growth of bulbs and increases resistance to pests. The powder can be sprinkled on top of the bed if it is not mulched with organic matter. Mixing ash and humus is not recommended, as this leads to the disappearance of nutrients from fertilizers.

Ash is added when digging the beds or a water concentrate is prepared for foliar feeding according to the following recipe:

  1. Sift 300 g of ash.
  2. Pour boiling water over and heat for 20 minutes.
  3. Strain the broth and dilute with 10 liters of water.
  4. Add a tablespoon liquid soap for sticking.

A common cause of yellowing of garlic feathers is lack of water. Chlorosis is caused not only by a lack of moisture, but also by an excess of moisture, as plant roots suffocate due to lack of oxygen.

When the water regime is disturbed, the lower leaves dry out first. Mulching with humus or peat will help solve the problem of a lack of irrigation water.

It is more difficult to help if the garlic is flooded. To prevent this from happening, in regions with high rainfall, vegetables are planted on raised beds. So that the roots can breathe, the surface of the soil is loosened after each watering, preventing the formation of a crust.

Depending on what is the cause of the pathology, chemical, folk or agrotechnical measures will come to the rescue.

Ready-made products

Garlic diseases are easier to prevent. To do this, before planting, soak the teeth in diluted water. pink color potassium permanganate or the drug Maxim. Fitosporin is suitable, in which the cloves should be soaked for 15-25 minutes. You can disinfect not the planting material, but the soil, by spilling the bed with a solution of one of the preparations.

Spray leaves caught by frost with growth stimulants: Silkom, Epin, Succinic acid. Stimulants increase plant immunity and promote the appearance of new leaves.

Silk contains triterpene acids produced coniferous trees. It is a natural regulator of plant growth and development that has a fungicidal effect.

Epin enjoys well-deserved love experienced gardeners. The drug contains an adaptogen, which has a pronounced anti-stress effect. Epin activates the plant's immunity at full capacity. As a result, garlic reacts less to frost, drought, and temperature changes.

The drug stimulates shoot formation, so young leaves quickly grow in place of dried leaves. Garlic damaged by frost or heat is sprayed with Epin once a week. Treatments are repeated until the plant recovers.

For spraying, use rainwater, not hard tap water.

Epin contains the phytohormone Epibrassinolide, which domestic scientists managed to synthesize. The drug is almost never used abroad, but in Russia most agricultural crops are treated with it.

In the spring, many summer residents are disappointed to find yellowed leaves of their garlic planting. And this is not only an unpleasant effect, but also a sign that the agricultural technology for growing winter crops has been violated. After all, following the yellowing of the leaves, the plant stops growing altogether, and the cloves rot. Why does it turn yellow? winter in 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 the 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 energy for development is taken from the leaves.
Basically, deep planting causes garlic to freeze. Therefore, to avoid the appearance of yellow leaves, it is advisable to plant this crop at a depth 5-7 cm. You can prevent the appearance of yellowness in the spring by covering the young seedlings with film.

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

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

Low acidity of soil for growing

In order for garlic to please you with its harvest, it should be planted in a neutral climate. If the soil on your site is highly acidic, it needs to be lowered. To do this, during autumn digging, add to the soil lime.
At increased acidity The rate of lime per hundred square meters is 50-70 kg, for acidic ones - 35-45 kg, for slightly acidic ones - 30-35 kg. After applying lime, the area must be thoroughly dug up.

Nitrogen deficiency

A lack of certain nutrients, including, also causes yellowing of the foliage and the appearance of a reddish tint.
If you notice that the tips of the leaves of winter garlic are turning yellow, the first thing to do is to urgently fertilize the soil with manure or urea (). In this case, it is recommended to water the plant directly over the leaves with urea.

Important! Fertilizers applied in the fall are washed out of the soil over 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 important at the beginning.
It would be a good idea to use highly effective additives that help loosen the soil and structure it, increasing the degree of absorption of moisture and nutrients.

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

Potassium deficiency

Potassium deficiency can also harm a young plant. In most cases, yellowing of leaves for this reason is observed in cold spring.
In this case, the roots 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 leaves, they droop and become thin.

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

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

Diseases of winter garlic and yellowing of leaves

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

  1. White rot. The leaves of the plant first turn yellow and wither, the bulbs become moldy and rot. The plants die one after another, and a fluffy whitish coating is visible on their surface. Most often, the disease occurs in the spring, with nitrogen deficiency.
  2. Basal rot. Although this type of fungus is present in almost all soils and does not cause any special problems if the plants do not experience stress. It manifests itself as yellowing of the leaves, which moves downwards. In principle, the symptoms are no different from white rot, only the plant rots more slowly. You need to combat this problem in advance by treating the planting material with a disinfectant solution (for example, “Tiram”).
  3. Aspergillosis or black mold. Most probably dangerous disease, which most often affects immature plants. Symptoms - the bulbs become soft, the leaves turn yellow.
  4. 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 winter garlic turns yellow due to fusarium, the first thing to treat the plant with is a solution potassium permanganate.
  5. Penicillosis or blue mold. It mainly affects the plant after harvest as a result of careless handling. The garlic gradually turns yellow and dies.
  6. Rust. Loves high humidity. It appears as yellowish spots and specks on the leaves. Over time, the foliage turns orange and brown. Fighting method- treatment of cloves before planting.

Garlic often turns yellow due to 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 plant’s cloves with a weak solution of potassium permanganate or “Maxim” and preparations, pouring the solution over the planting material for 15-30 minutes. Even if you did not do this before planting, you can already water the beds with the solution.

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