Why do garlic leaves turn yellow? spring and what to do to grow it properly. This phenomenon affects many summer residents and, as a rule, garlic leaves turn yellow from the tips. After a while, the yellowing increases and plant development begins to slow down, with the bulbs eventually growing smaller.

The main causes of yellowing of garlic leaves in spring

Usually the leaves of winter garlic begin to turn yellow in early spring. At this time, the garlic falls under severe frosts, and the leaves may turn yellow.

Also, the bulb can become infected with various diseases. You can determine the cause of the phenomenon yourself - pull out the bulb and look at the roots, they have turned black or if mold has appeared on them.

The reason for the yellowing of the leaves may be acidic soil or a lack of nitrogen, magnesium and potassium in it. In addition, garlic needs regular watering, so keep that in mind.

Diseases and pests of garlic

Fusarium, white rot, bacterial rot and black mold - disease data may cause yellowing of the leaves. To prevent these diseases, it is recommended to water the beds with a solution of table salt (use 2 tablespoons per 10 liters of water) or soak the cloves in a solution of manganese before planting.

There is also a stem nematode, and in order to get rid of it, many gardeners advise sowing plants such as mint, calendula, marigolds, hyssop, coriander, savory in the aisles, all of which will help you scare away the pest.

Soil influence

If your soil in the area is too acidic, then you need to lower its acidity. To do this, add lime of any kind, before the autumn digging. After lime is applied, the soil is dug up and the beds are prepared for planting.

With a lack of potassium, potassium sulfate should be used at the rate of 15-20 g per 10 liters of water, and with a lack of magnesium, foliar fertilizing with magnesium sulfate at the rate of 120-180 g per 10 liters of water can be used.

With a lack of nitrogen in the soil, apply nitrogenous fertilizers to the soil during the period of active growth - in early spring. You can use ordinary humus or urea, as well as other nitrogen-containing mixtures.

Often the feathers of garlic that have gone into growth turn yellow. If measures are not taken in time, there will be no good harvest.

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

Causes

Usually yellowing - chlorosis - begins at the tips. 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;
  • wrong water regime;
  • cold weather.

There are many ways to determine what caused yellowing.

Garlic planted last season turns yellow

When winter garlic turns yellow in early spring, this means that the plants have come under frost.

Yellow garlic in warm weather

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

Yellowing is caused by two diseases that lilies are susceptible to: 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 quickly, starting from the end. A pinkish coating appears in the sinuses, then the aerial part is covered with brown stripes. If you dig an onion, it is immediately noticeable that its roots have almost disappeared, and the bottom has become soft and watery.

The disease is common in the southern climate, but gardeners in the middle zone also encounter it in hot years. Yield losses in Fusarium can reach 70%.

bacterial rot

Bacterial rot affects bulbous crops. The disease is manifested by brown dots on the surface of the teeth. Subsequently, the heads acquire a "frozen" appearance and smell unpleasant. The feathers of garlic turn yellow, then the leaves and arrows dry up and die off, starting from the ends.

Sources of the disease are bacteria that live in the soil. Microorganisms enter the plant through damage caused by onion flies, mites, nematodes and thrips.

Nematode

The 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, 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 is Garlic Missing?

Sometimes garlic in the garden turns yellow due to lack of nutrition. More often, the vegetable is deficient in nitrogen and potassium. You can correct the situation by feeding.

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

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

Those who prefer to fertilize the garden with mineral water can use urea and potassium sulfate as a prevention of yellowing garlic leaves. The last fertilizer still contains sulfur that is useful for garlic.

The chemical industry produces specialized fertilizers for garlic: Agricola 2, Kemiru Fertika. Top dressing is dissolved in water and planted plants are watered or scattered on the surface of the soil before digging.

You can carry out foliar top dressing. The procedure is useful if the leaves of young plants turn yellow. Urea or potassium sulfate is diluted at a concentration of a teaspoon per liter of water. The leaves are sprayed from a spray bottle with a fine spray. Droplets of the working solution that have fallen on the leaf blades will be absorbed, and the yellowness will disappear.

All onions adore top dressing with ashes, as it contains a lot of potassium, which promotes the growth of bulbs and increases resistance to pests. 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.

Ashes are applied when digging the beds or prepare an aqueous concentrate 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 of sticky liquid soap.

A common cause of yellowing garlic feathers is a lack of water. Not only lack, but also excess moisture leads to chlorosis, as plant roots suffocate due to lack of oxygen.

In case of violation of the water regime, the lower leaves dry out first. Mulching with humus or peat will help solve the problem with a lack of irrigation water.

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

What to do if the garlic turns yellow

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

Ready funds

Diseases of garlic are easier to prevent. To do this, before planting, soak the teeth in potassium permanganate diluted to pink or Maxim preparation. Phytosporin is suitable, in which the teeth can be kept for 15-25 minutes. It is possible to disinfect not the planting material, but the soil by spilling the bed with a solution of one of the preparations.

Spray the leaves stuck by frost with growth stimulants: Silk, Epin, Succinic acid. Stimulants increase plant immunity and promote the emergence of new leaves.

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

Epin enjoys the well-deserved love of experienced gardeners. The composition of the drug includes an adaptogen, which has a pronounced anti-stress effect. Epin turns on the immunity of the plant at full power. As a result, garlic reacts less to frost, drought, and temperature changes.

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

For spraying, take rainwater, not hard tap water.

Epin contains the phytohormone Epibrassinolide, which was synthesized by domestic scientists. Abroad, the drug is almost never used, but in Russia it is used to treat most crops.

Succinic acid is a product of amber processing. Universal medicine for onions and garlic. It not only stimulates growth and improves immunity, but also serves as a source of trace elements. Stimulant-treated plant:

  • becomes immune to major diseases;
  • quickly recovers after being damaged by pests;
  • tolerates cold and drought.

It is important that it is impossible to overdose the stimulant. Plants take from the solution only the required amount of the substance.

First, a concentrated solution is prepared by diluting a gram of acid in a small volume of heated water. The concentrate is poured into a 10 liter bucket filled with clean water, and a working solution is obtained suitable for foliar spraying and watering.

YAK can be purchased not only in gardening stores, but also in a regular pharmacy, as the product is an adaptogen and an immune stimulant not only for plants, but also for humans.

Insecticides are used against harmful insects: Fufanon, Karbofos, Aktellik.

Folk methods

If small worms can be seen at the base of the yellowed leaves, this means that an onion fly has laid eggs on the garlic. Getting rid of the pest is easy. A glass of table salt is dissolved in a bucket of water and the tops are sprayed. After the worms disappear.

For each plant spend 1 glass of saline. The next day, the bed is shed with plain water and the garlic is fed with ashes.

But it is useless to fight the nematode with folk methods and even "chemistry". Crop rotation also does not help, since the worms can be in the garden without food for many years. But it is known that the pest lives only in acidic soils. If the bed is infected with a nematode, you need to add lime or dolomite flour before planting garlic.

Tagetis and calendula sown between the rows will help protect the garlic. Pests do not like plants, as their juice is poisonous.

To repel onion flies, use shag mixed with lime 1: 1. The beds are covered with powder during the first and second departure of pests.

Prevention of yellow garlic

Prevention of garlic diseases is a properly designed crop rotation. The culture is planted in the old place no earlier than after 3 years. During this time, the spores of bacteria and fungi in the soil lose their harmfulness.

Another prevention of chlorosis is the correct agricultural technology, because serious violations can become the cause of yellowing:

  • Shallow landing, leading to freezing. Feathers do not turn yellow from the ends, but grow back chlorotic.
  • Premature landing. Early planted spring garlic falls under spring frosts. Winter varieties in the middle lane are planted no earlier than October, trying to guess the planting time so that the clove has time to take root in the soil, but does not throw out the leaves.
  • Soil acidification. Alliums prefer a neutral PH. In too acidic soils, it is necessary to add deoxidizers - lime, ash, dolomite, chalk, eggshells, cement.

To protect garlic from diseases caused by microorganisms, you need to ensure that the planting material is healthy. Do not plant cloves with rot spots and traces of mold or use fresh manure when planting garlic, as it contains pathogen spores.

So, garlic can turn yellow for many reasons. Before starting treatment, be sure to diagnose and identify the cause of the problem. Only then take measures to eliminate the pathology.

And they are waiting for a rich and healthy harvest, but suddenly in the spring the leaves of the plant turn yellow and wither. Familiar situation? Unfortunately, this happens quite often. Then the gardeners begin to look for the answer to the question: why did this failure occur in the garden? There can be several reasons: improper planting, processing, feeding, 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 useful substances. It is eaten raw, seasoned with meat, salads and more. You can eat not only onions, but also garlic leaves. 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 autumn gives a generous harvest. But you can’t store it for a long time - only up to six months. Spring garlic will not give birth so richly, but it can be stored for about a year.

But why do its leaves turn yellow? In autumn, garlic can be planted too early. Then he will have time to ascend before the first frost. That is, they will not have time to leave for the winter. These early shoots will fall under frost, which will lead to yellow leaves. A similar problem can happen with spring planting, only late spring frosts threaten there.

Therefore, when planting, you need to carefully monitor the temperature regime, and sow garlic on time. Sometimes, in order to insure, winter planting is carried out even in early December, and spring planting - in early May.

Another important indicator is the acidity of the soil. Too high acidity for garlic is extremely harmful. It needs to be planted in soil with a neutral pH. Reduce acidity with lime, which is applied in autumn when digging.

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

To keep the leaves of garlic green, it is very important to properly water the plant. In a dry summer, you need to generously water the garlic, otherwise not only will the stems wilt, but the bulbs will not grow as they should. To keep 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 number 2: Fertilizer and top dressing

The lack of nutrients in the soil can lead to the yellowness of garlic leaves. Most often we are talking about 2 minerals - potassium and nitrogen. You may also be deficient in 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 can also be the cause of the yellowing of garlic leaves. It is necessary not only to know about pests and diseases, but to be able to recognize and eliminate them.

  1. Fusarium is a fungal disease that affects seeds and soil. It leads to the appearance of yellow-brown stripes on the leaves of the plant. This fungus loves moist air. Fusarium can be eliminated with the help of a manganese solution, which is used to treat planting material. For prevention, 3 days before planting, you need to pour boiling water over the future beds.
  2. Peronosporosis is another harmful fungus that breeds in a humid environment and high temperatures. 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 peronosporosis, you need to use chemical sprays.
  3. The stem nematode is a worm from the primary cavity. It is very small - only a few micrometers - but does a lot of harm by laying eggs in a garlic bulb. They corrode the cloves, and the leaves quickly turn yellow from this. To eliminate the nematode, you need to treat the seed with ordinary saline. And the soil before planting should be flavored 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 its eggs in the plant itself, causing the garlic to rot and its leaves to turn yellow. To scare away this insect, garlic is planted next to carrots. Also, seedlings can be treated with carbon ammonium salt.

Attention! Insects live and breed 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 spring:

  • frost 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 identified, it can be easily eliminated and prevent the problem from reoccurring in the future.

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

Why garlic leaves turn yellow: video

Yellowed tips of garlic in the spring is one of the problems that a summer resident may encounter when growing garlic in the 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 - strong spring frosts

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

You yourself will understand that garlic turns yellow in the spring precisely for this reason, if you wake up in the morning in the country, you will see grass in hoarfrost 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 bed with plantings or spray yellowed garlic leaves.

2 Cause - fungal and other diseases

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

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

Determining that the 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 the fungal disease. From diseases of garlic, and other vegetables, prevention is best. 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 previously processed the planting material, then there are options for how to water the 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.

A pest that provokes the development of a stem nematode on garlic will be scared off by calendula planted nearby, marigolds, mint, coriander, hyssop and savory, they will scare away the pest.

But the most important thing, how 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 in no case 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 soils. Special instruments help to determine the level of acidity. And if you determine that your garden plot has an acidic soil composition, then the acidity must be reduced. To do this, before the autumn digging of the garden, it is necessary to add lime to the soil.

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

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


4 reason -lack of nutrients in the soil

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

Garlic turns yellow than water and feed:

  • Nitrogen - is very quickly washed out of the soil, and it is extremely necessary during the period of active plant growth - in early spring. Therefore, in the spring, you can make any nitrogen-containing mixtures, or you can get by with simple humus or urea.
  • With 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 foliar fertilizing with magnesium sulfate at the rate of 100-200 g per 10 liters of water and water

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

  • Loosen the row spacing carefully. Make a groove 1 - 2 cm deep. Pour fertilizer in granules into it. It can be urea (carbamide) or other complex mineral fertilizer. Sprinkle the granules with earth. After that, water the entire garden abundantly so that the fertilizer dissolves, since any plants absorb nutrients only in dissolved form. After that, you can mulch the wet bed with dry earth or compost so that the soil remains moist as long as possible.
  • Prepare a solution for watering the beds. Dissolve 1 tablespoon of dry mineral fertilizer in 10 liters of water. For top dressing, urea or Fertik Lux is suitable. Garlic is poured with this solution - 10 liters of solution per 1 sq. m. This option for feeding garlic with yellow leaves is even better, since liquid fertilizer gets to the roots of plants faster.
  • From organic fertilizers, you can also make good dressings for garlic. Prepare an infusion of cut green grass, weeds without seeds, with the addition of wood ash. With a solution of this liquid "green manure" you can water the garlic under the root or make foliar top dressing.

5 reason - ne regular watering

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