Why can garlic in the garden turn yellow? Garlic turns yellow in spring - how to save the harvest? Cervical rot or gray rot

Yellowed tips of garlic in the spring are one of the problems that a summer resident may encounter when growing garlic in beds. There are several reasons why garlic turns yellow and, of course, there are proven recipes that will tell you what to do if the garlic turns yellow in the spring.

1 Reason - severe spring frosts

Yellowing of winter garlic leaves in spring can be caused by severe spring frosts.

You yourself will understand that garlic turns yellow in the spring for this very reason if you wake up in the morning at your dacha and see grass covered in frost and a thin crust of ice on the puddles.

What to do if there was a spring frost? Stimulants HB-101, Epin, Zircon will help you. Dilute the product according to the instructions and water the garden bed or spray the yellowed leaves of garlic.

2 Reason - fungal and other diseases

There are several diseases that cause garlic to turn yellow in the garden in the spring. This:

  • white rot,
  • black mold,
  • bacterial rot,
  • fusarium
  • and stem nematode.

Determining that a plant is sick is easy. Pull the garlic bulb out of the ground and if you see blackened roots on the bottom and mold that has appeared, then you need to fight a fungal disease. Prevention is the best way to prevent diseases of garlic and other vegetables. Before planting, you need to soak the cloves in a solution of potassium permanganate, or special preparations “Maxim” or “Fitosporin” for literally 15 - 25 minutes.

If you have not pre-treated planting material, then there are options for how to pour garlic. For example, a solution of table salt - two tablespoons per 10 liters of water. You can also water the beds with garlic using “Maxim” or “Fitosporin” solutions.

The pest that provokes the development of stem nematode on garlic will be repelled by calendula, marigolds, mint, coriander, hyssop and savory planted nearby; they will repel the pest.

But the most important way to prevent garlic diseases, in which the leaves turn yellow, is to follow the planting rules:

  1. Do not apply fresh manure;
  2. Take into account the rules for alternating planting vegetables in the garden and under no circumstances plant garlic in the place where potatoes were previously grown.

3 Reason - unsuitable soil

Planting in highly acidic soils can also cause garlic leaves to turn yellow in May. This plant should be planted in neutral soil. Helps determine acidity level special devices. And if you determine that your garden plot has an acidic soil composition, then the acidity needs to be reduced. To do this, before digging up the garden in the fall, you need to add lime to the soil.

  • for strongly acidic soils, add 50-70 kg of lime per one hundred square meters,
  • on sour - 35-45 kg
  • and for slightly acidic ones - 35-30 kg.

Then the garden is dug up and beds are prepared for planting vegetables.


4 Reason -lack of nutrients in the soil

A lack of nitrogen, potassium and magnesium in the soil is also the reason why garlic turns yellow in the spring. What to do in this case? Apply fertilizing correctly.

Garlic turns yellow, what to water and feed:

  • Nitrogen is very quickly washed out of the soil, and it is extremely necessary during the period of active plant growth - early spring. Therefore, in the spring you can add any nitrogen-containing mixtures, or you can get by with simple humus or urea.
  • If there is a lack of potassium, potassium sulfate is added at the rate of 15-20 g per 10 liters of water.
  • Magnesium deficiency can be avoided by supplementing foliar feeding magnesium sulfate at the rate of 100-200 g per 10 liters of water and pour

More recipes on what to do and how to feed winter garlic with yellowed leaves:

  • Carefully loosen the rows. Make a furrow 1 - 2 cm deep. Pour granular fertilizer into it. This may be urea (carbamide) or another complex mineral fertilizer. Sprinkle the granules with soil. After this, water the entire bed generously so that the fertilizer dissolves, since any plants absorb nutrients only in dissolved form. After this, you can mulch the wet bed with dry soil or compost to keep the soil moist for as long as possible.
  • Prepare a solution for watering the beds. Dissolve 1 tablespoon of dry mineral fertilizer in 10 liters of water. Urea or Fertik Lux are suitable for feeding. Water the garlic with this solution - 10 liters of solution per 1 square meter. m. This option for feeding garlic with yellow leaves even better, since the liquid fertilizer gets to the plant roots faster.
  • From organic fertilizers you can also cook good feeding for garlic. Prepare an infusion of cut green grass, seedless weeds with the addition of wood ash. A solution of this liquid “green fertilizer” can be used to water the garlic at the root or to do foliar feeding.

5 Reason - ne regular watering

Caring for garlic in the spring, if the leaves turn yellow in May and June, means regular watering and loosening the soil. Then you will avoid the appearance of yellow leaves and collect good harvest garlic

It is frustrating for any gardener when their plants do not grow and develop as they should. In spring and summer, some gardeners are faced with a common problem - garlic turning yellow. To protect your plantings from yellowing and preserve future harvest after winter, you definitely need to find out the reason why this happens and what to do.

Both winter and spring garlic can turn yellow; as a rule, it turns yellow at the beginning from the stem and stem parts. To treat, you need to treat or fertilize with special means.

The main problems with this spicy vegetable fall into three broad categories:

  • Improper care
  • Diseases
  • Pests

The main diseases of garlic include the following:

  • Fusarium
  • Bacterial and neck rot

Diseases and pests are serious problems that need to be diagnosed in time and measures taken to treat plants. Each disease has its own characteristics.

Rust and how to deal with it

The most common garlic disease in Russia is rust. A serious problem that needs to be dealt with immediately.

Externally, the disease manifests itself as follows: it spreads small orange spots over the entire surface of the leaves garlic In appearance, “rust” looks like small, yellowed, rust-colored bumps. If the gardener does not react in time, the plant gradually turns black and dies.

By its nature, rust is fungal disease. Most often, the disease remains in the ground from last year. Therefore, as a preventive measure, it is not recommended to plant plants in the same place every year. In addition, garlic beds should be located away from onion beds.

If rust-affected leaves are found, they must be cut off immediately. If the infection is widespread, it is worth using and treating chemicals. They are used strictly according to the instructions.

Fusarium - how to treat for control

Fungal disease. In common parlance it is called “rot.”

Infection occurs through the soil and if low-quality seed is planted. The development of the disease occurs at temperatures 13-30 degrees and at high humidity . Externally, the disease manifests itself as follows: garlic leaves begin to turn yellow at the tip, dry out and die. In this case, the roots rot, the development of the head stops and the plant dies.

As a preventive measure, it is imperative to monitor the condition of the planting material. You can also additionally disinfect and water the soil with special chemicals.

To combat the emerging disease, you need to use antifungal agents, according to the instructions or method.


The popular name for the disease is downy mildew. The disease is fungal in nature and is widespread in all regions of Russia. Downy mildew is especially active at high humidity.

Externally, the signs of the disease look like focal leaf damage. At the same time, the growth and development of the vegetable slows down, the leaves change color and shape, and the flower stalks turn yellow.

To avoid infection in your garden beds, you need to plant only healthy seed and monitor soil moisture. It is better to place beds with plants in sunny and ventilated places. garden plot. If the disease does affect garlic, you need to use special means.

Bacterial and neck rot


Bacterial diseases affect garlic less often than fungal diseases. Cervical rot affects itself cloves. To avoid this disease, you need plant vegetables annually different places and monitor the health of the seed.

It is also worth using special sprays to control pests. Insects can aggravate the disease and are even sometimes its source.


Popularly this disease is called green mold. The causative agents are fungi. The disease most often occurs during improper storage. The heads deteriorate and are destroyed from the inside.

Reasons why garlic may turn yellow in spring

In summer time Yellowing of the leaves indicates its maturation. However, in the spring yellowness indicates problems.

There are main reasons for this phenomenon:

  • early boarding;
  • frost;
  • acidic soil;
  • lack of watering;
  • pests

Early planting and frosts

More often turns yellow winter garlic, it's happening due to spring frosts. If spring garlic is planted too early, it can also be affected low temperatures. Young garlic sprouts are covered with film - this protects them from hypothermia.


If negative impact frosts still could not be avoided, it is worth watering the plants with special development stimulants. These drugs will help the vegetable develop normally in the future.

Acidic soil

Spicy vegetable grows and develops well in the ground with neutral balance. Excessively acidic soil causes yellowing of leaves. In addition, the soil must be loose and well-permeable to oxygen.

You can reduce acidity by feeding the soil with lime. The proportions of this additive are calculated based on the characteristics of the land.

Insufficient watering

In young plants, yellowing of leaves can be caused by a lack of moisture. In May - June, the formation of the vegetable occurs. At this time it is necessary regularly loosen the soil and carry out timely watering.

To water the vegetable, use settled water that has been warmed in the sun.


Pests

The most common insects that spoil garlic and onions are onion fly, nematode, root mite, tobacco thrips. They can cause irreparable harm to the harvest of this spicy vegetable.

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. Renew planting material every five years.

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 rot of the head 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.
  • At a certain time, water winter garlic in 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 of 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, feed the plant, 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 in the leaf are transferred to the 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 display green, lush and healthy garlic stalks!

And they expect a rich and healthy harvest, but suddenly in the spring the leaves of the plant turn yellow and wither. Is this a familiar situation? Unfortunately, this happens quite often. Then gardeners begin to look for an answer to the question: why did this failure happen in the garden? There may be several reasons: improper planting, processing, fertilizing, etc. What can be done to prevent this from happening?

Reason #1: Planting, care and temperature

Garlic is a vegetable popular in almost all cuisines of the world. This is easily explained by its specific bright taste and composition rich in nutrients. It is eaten raw, seasoned with meat, salads and much more. You can eat not only the bulbs, but also the leaves of garlic. Therefore, it is a pity if they turn yellow, dry out and die. One of the first reasons for this trouble is problems when sowing garlic.

There are 2 ways to sow garlic:

Both methods have both pros and cons. Garlic planted in the fall gives bountiful harvest. But you can’t store it for a long time - only up to six months. Spring garlic will not yield as richly, but it can be stored for about a year.

But why do its leaves turn yellow? In the fall, garlic may be planted too early. Then it will have time to rise before the first frost. That is, he will not have time to leave for the winter. These early shoots will be exposed to frost, which will cause the leaves to turn yellow. A similar problem can happen with spring planting, only there there is a threat of late spring frosts.

Therefore, when planting, you need to carefully monitor temperature conditions, and sow garlic on time. Sometimes, to be on the safe side, winter planting carried out even in early December, and spring - in early May.

Another important indicator is soil acidity. Too high acidity is extremely harmful for garlic. It must be planted in soil with a neutral pH. Reduce acidity with lime, which is added in the fall when digging.

Attention! To cultivate very acidic soil you will have to spend 50-70 kg of lime per hundred square meters, for acidic soil - up to 45 kg, slightly acidic - up to 30 kg.

To keep garlic leaves green, it is very important to organize the plant. proper watering. In dry summers, you need to water the garlic generously, otherwise not only will the stems wither, but the bulbs will not grow as they should. To retain moisture in the soil longer, you can mulch the beds with straw. But too much humidity can damage the plant, creating a positive environment for the development of fungal diseases.

Reason No. 2: Fertilizer and feeding

Lack of garlic leaves may turn yellow nutrients in the ground. Most often we are talking about 2 minerals - potassium and nitrogen. There may also be a lack of magnesium. What to do in this case? It's simple - feed the plant with organic and mineral fertilizers. There are several ways to feed garlic:

Reason #3: Diseases and pests

This may also be the reason why garlic leaves turn yellow. You need to not only know about pests and diseases, but be able to recognize and eliminate them.

  1. Fusarium is a fungal disease that affects seeds and soil. It causes yellow-brown streaks to appear on the leaves of the plant. This fungus loves moist air. Fusarium can be eliminated using a manganese solution that is used to treat planting material. For preventative purposes, 3 days before planting, you need to pour boiling water over the future beds.
  2. Downy mildew is another harmful fungus that multiplies in a humid environment and high temperature. The initial stage of the fungus is pale green spots, over time they acquire a gray coating. Eventually the garlic leaves turn yellow and die. To remove downy mildew, you need to use chemical sprayers.
  3. The stem nematode is a worm from the protocavity. It is very small - only a few micrometers, but does a lot of damage by laying eggs in the garlic bulb. They eat away the cloves, and the leaves quickly turn yellow. To eliminate the nematode, you need to treat the seed with ordinary saline solution. Before planting, the soil should be fertilized with tobacco dust or ash.
  4. Onion fly - in appearance this insect resembles an ordinary fly. Its length is 6-7 mm. The onion fly also lays eggs in the plant itself, causing the garlic to rot and its leaves to turn yellow. To repel this insect, garlic is planted next to carrots. The seedlings can also be treated with ammonium carbonate salt.

Attention! Insects live and reproduce best in contaminated soil that has not been cultivated for a long time.

So, we can briefly list the reasons why garlic leaves may turn yellow in the spring:

  • frosts during early shoots;
  • lack of nitrogen, magnesium and potassium in the soil;
  • early boarding;
  • infected planting material (nematode, pathogenic fungi);
  • onion fly damage;
  • drought and poor watering.

Once the cause is determined, it can be easily eliminated and prevent the problem from recurring in the future.

If you follow all the rules for planting, processing and feeding, you can get a good harvest of garlic. And its leaves will be lush and green - a real decoration for the garden of good owners. In healthy and properly planted garlic, the lower leaves begin to turn yellow by the end of July - this is a sign that the harvest can be harvested.

Why do garlic leaves turn yellow: video

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 acquire 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 with 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 the fertilizer.

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.
