Why planted onions turn yellow what to do. What to do so that the onion does not turn yellow in the garden

Usually onions turn yellow in spring in such a way that the part that goes below the bulb itself looks quite healthy, but the very tips of the feathers begin to turn yellow. Gradually, this yellowing reaches up to the middle of the pen. This may be caused various reasons. For example, from life onion fly when she lays her larvae. Maybe the onion fly has nothing to do with it, and your onion simply lacks nitrogen, or the soil under it is very acidic. In this case, it is desirable to know the exact cause of the yellowing of the onion. But, if this is a problem for you, then you can apply simple folk remedies, which are complex in nature, and will help you immediately act on all these three causes at the same time.

If the onion feather turns yellow. What folk remedies can be used?

There are several options. Let's start with wood ash. Type a bowl of such ash, heat water in the sun (10 liters), prepare table salt (100 grams in total), and one ampoule of ammonia. We fall asleep (or pour) all these components into the water, stir them well there and water the yellowed onions. Often you do not need to do this, the 1st time in 10 days will be enough. We maintain this watering schedule with this tool until your onion completely comes to its senses and turns green.

You can use a strong solution of potassium permanganate to soak the onion in it just before planting it. When planting such bulbs, the grooves will need to be sprinkled with a little more salt. This method of planting greatly helps to protect the onion from the fly. Treating the beds with salt protects not only onions. This helps to reduce the worminess of the radish.

If the tips of the onion turn yellow, then you can try another processing option. To do this, you need potassium permanganate (2 sachets), in addition to it, a couple of bottles of iodine (5 ml each), half a kilogram of soda. All this is first diluted in water - in 10 liters. And then, the already prepared composition is bred again - 1:10, after which it can already be used for watering onions.

Iodine will help kill harmful fungi on onion feathers, and soda will significantly reduce the acidity of the soil. This will have a positive effect on onions, it will also be useful for carrots.

Powdery mildew on onions

This is another reason why onion leaves turn yellow. In this case, you can process Bordeaux mixture one percent concentration.

There is another folk way solutions to this problem. To do this, a solution is poured under the root, which consists of potassium permanganate and salt (a glass of each component) per 10 liters of water. As a result, you should get a solution of pink in color. Such watering is carried out only 2 times, and the interval between each run should be one week.

Another option is to pour a couple of tablespoons of kerosene into the same 10 liters of water, after which, again, pour the onion under the root. The beds with onions between the rows can also be sprinkled with sand, into which naphthalene is mixed.

Wrong watering

Onions can also turn yellow if you simply do not provide them with the right amount of water. And it should be watered 6 times a month.

If the feather of the bow falls. What can be done?

In this case, the onion can be watered again with a solution of kerosene (only a tablespoon per bucket of water). They do this 3 or 4 times. You can sometimes pour it with potassium permanganate, and sprinkle a little ash. It happens that the feather of the bow falls as if it had been mowed down. It's the owl attacking him. If it just falls, then most likely it's just such a variety.

It is impossible to imagine the hostess' kitchen without onions. Let tears flow from him like a river, but in many dishes a vegetable is necessary. Therefore, in private plots, onions are grown everywhere. It is planted either for the winter or in the spring. Onions are growing well. Rarely enough is capricious and shows discontent. But it signals serious problems. Often - yellowing of the pen.

What to do if the onion turns yellow? Everything depends on the season. If the onion began to turn yellow in June, for example, then this is bad. The plant is not happy. Or someone wound up in the garden. You need to figure out why the onion feather turns yellow, and take action. If this happens at the end of July, then there is no reason for concern. The harvest has begun to ripen. We'll clean up soon.

Provocateurs of yellowness

Why do onion leaves turn yellow? Causes of the problem: a pest has wound up, there is not enough nitrogen in the soil, the plant lacks moisture. Rescue measures will depend on the specific cause.

Pests

As a rule, the plant is damaged by a fly and a secretive proboscis.

onion fly

Symptoms of its presence: feathers turn yellow and wither early, a larva can be found in the bulb, the vegetable rots, and the plant is pulled out of the ground very easily, even accidentally during weeding.

Pest targeting:

1. Size adult- about seven millimeters. The body is yellowish-gray with dark sparse stripes.

2. Larva - white worm with cone-like processes at the end. It can be seen in the bulb or in the soil near the plant.

The pupae of flies hibernate in the soil. In spring, the pupae wake up. Egg laying coincides with the flowering of dandelions. A week later, the larvae appear. They sneak into the bulb and feed on it.

Protective measures:

deep digging of the soil before sowing;
early boarding;
neighborhood with carrots, the smell of which repels flies;
destruction of infected plants;
sprinkling the earth around the onion with ashes mixed with tobacco dust;
cleaning from the garden of all plant residues.

Onion Stalker

A very dangerous pest that eats feathers from the inside. Signs of its invasion: on the leaves - white spots and longitudinal stripes, yellow tips of feathers, twisting and drying of the feather. For young plantings, both adults and larvae are dangerous.

How to recognize a pest?

1. Adult beetle - small insect up to two millimeters long. The body is covered with light scales. The tarsi and elytra are brownish. There is a light stripe at the base of the elytra.

2. The larva is a light worm with a dark head.

Hidden trunks hibernate in the ground, grass, shrubs or unharvested onions. They feed on them in the spring, gradually moving to fresh plantings. The female gnaws the onion feather and lays eggs there. After two weeks, the larvae emerge. They eat the internal contents of the feathers, and then descend into the soil to pupate.

Protective measures:

timely cleaning of plant residues;
sowing on ridges remote from the plantings of the previous year;
regular loosening of row spacing;
cutting off damaged feathers plus loosening.

Lack of nitrogen in the soil

It can be observed both on dry days and on rainy days. Nitrogen is absorbed in dissolved form, so moisture is needed. At the same time, after heavy rainfall, nitrogenous compounds go too deep, from where the roots of the plant cannot absorb them.

To compensate for the deficiency of nitrogen, onions are periodically fertilized with saltpeter, ammonium sulfate, urea or slurry.

lack of moisture

During the period of active growth and gaining strength, onions need regular watering.

the plant is watered before and after weeding;
pour water into the grooves made between the green bushes;
with dense plantings, when you have to water over the feathers, use a watering can so that the water does not wash out the soil near the bulb;
the need for watering is checked with a finger; if the soil is dry at the depth of the nail, then you need to water it;
one and a half months before harvesting, watering is stopped.

Feather Rescue

Consider a few folk methods comprehensive problem solving. That is, such recipes that allow you to immediately eliminate several causes.

1. In ten liters warm water dissolve half a glass table salt and one ampoule of ammonia. Add three zhmenki ash. Water this composition once every ten days. Until the feathers turn green again.

2. planting material soak in strong potassium permanganate and land in rows sprinkled with salt.

3. For half a bucket of water - half a tablespoon of iodine, two bags of potassium permanganate and five hundred grams of soda. This is a concentrated formula. It must also be diluted in water in a ratio of 1:10. And already divorced to water.

4. Sprinkle the aisles with sand mixed with naphthalene.

5. Water the onion with salt water with potassium permanganate.

That's all the subtleties. And finally - a photo interesting ideas serving onions to the table.

Original feather salad bowl:

Straw was used as a support. The bottom of the basket is a piece of black bread. Salad ingredients should be combined to taste with onions.

Onion palms:

Barrel - skewers for barbecue with strung olives. Foliage - green onion feathers.

And this is just onion beauty:

Have a beautiful harvest!

Onion is a non-capricious culture, resistant to temperature extremes, drought, long rains, not very demanding on soil and care. Beneficial features it is difficult to overestimate it - the most sought-after vegetable in any kitchen and the main winter healer. Onions are grown everywhere, ranking among the most popular horticultural crops an honorable third place after potatoes and cabbage. The process of forcing a feather and cultivating beautiful root crops is an exciting and rewarding activity, but only if the plants do not get sick.

Weather problems

The most common problem with onion beds is sudden yellowing and drying of the feather tips. Without finding out the cause of this phenomenon, you should not run around in a panic with a sprayer and bring the entire periodic table into the ground. A simple drought can cause such a reaction. High temperatures within a week, the lack of precipitation and watering leads to a violation of sap flow, but not to a loss of the ability to increase the fruit mass. Of course, green beds look more beautiful than yellowed ones, but the goal of gardening is not only aesthetic pleasure. The final result - large, filled onion heads - is not affected by this drying.

A similar problem may haunt gardeners who know about the frost resistance of the crop and planted the seedlings too early. The frostbitten tips of the seedlings soon turn yellow and dry out, giving the same picture as during a drought, but without affecting a full-fledged crop.

Onions turn yellow from weather conditions - how to feed?

If the cause of drying is return frosts, then the care of the beds does not change in any way. The feather will grow back, the dry tips in the total green mass will be invisible to either the host or the plant. If the weather is dry for a long time, the site should be watered with sprinkling for 2-3 days in a row. To restore the strength of damaged plants, sprinkle the ground between them with ash in the calculation of a half-liter jar for 1 square meter or spill with ash solution. To prepare it, you need to dilute the same amount of ash in a bucket of water and leave for 3-4 days, stirring regularly. The yellowed tips will no longer turn green, but the plant will quickly get out of a state of stress.

Lack of nitrogen

Another reason for yellowing onions - acute shortage nitrogen in the soil. Diagnosing this “disease” is easy - it affects, as a rule, not only onions. All cultures living in the neighborhood also become faded in color with light veins, the fruits become smaller and change shape, sometimes the edges of the leaves are bent and spots similar to lichen are formed. Most often, this ailment is caused by prolonged rains or excessive watering, when nitrogen is simply washed out of the upper nutrient layer to the depth where it becomes inaccessible to the roots.

Onions turn yellow from a lack of nitrogen - how to water?

The only way to cure plants is to apply nitrogen fertilizers. But this must be done smartly and dosed, since active vegetative processes begin from excessive nitrate nutrition - an increase in green mass to the detriment of head formation. Fertilizer is prepared from plant components:

green grass;
hay, straw;
any weeds, it is possible with seeds;
food waste of plant origin - vegetable peelings, sunflower husks, tea and coffee grounds.

Water is poured into the barrel (basin, bucket), preferably rainwater, everything that was collected on the site and in the kitchen is thrown. We also add sweet things here - old candied jam, crystallized honey, sour fortified wine, expired condensed milk, or at least a couple of tablespoons of sugar. Stir this mixture well and let stand until active fermentation, which we learn about bad smell. In hot weather, the solution will be ready in 3-4 days, in cool weather - in 2 weeks. We dilute 1 liter of nitrogen compote in a bucket of water and generously fertilize the beds with onions. It is better to do this after or during rain on damp ground. If the weather is dry, then the garden must first be watered. This top dressing is absorbed easily and quickly, supplying plants not only with nitrogen, but also with a host of other nutrients. useful components. The most significant components of herbal infusions are nettle, plantain and dandelion. This is a real storehouse of trace elements that stimulate growth, increase plant resistance to fungal diseases.

Onion pests

The main enemies of the onion culture are the stem nematode, the onion fly and the secretive trunk. It is extremely difficult to see them on a plant due to their small size and inconspicuous color. They can get into the garden with seed, fly in and crawl from neighbors and spend the winter in the beds in the remains of last year's crop. characteristic distinguishing feature residence of unauthorized persons on the bow - the feather turns yellow not at the tips, but along the entire length.

Yellowing from pests - what to water?

Folk remedies for onion flies and secretive trunks are saline and all the bitter sprays that exist in nature. Tinctures of tobacco, pepper, mustard, garlic are prepared for 3-4 days, the concentration - the more the better. If the onion has already turned yellow and there is little time for cooking, you need to throw all the additives into the water and bring it to a boil. After cooling under the lid, you can immediately start spraying. For a nematode, a bitter soul is not enough and the remaining liquid is poured out between the rows of onions. From a fly, there is another proven remedy - insist the skins of green nuts in water for at least a day and generously shed the area with this solution.

Salt solution can be used both for prevention and for destruction. 10 tablespoons in a bucket of water, mix well and pour over the plants and under the root. If this does not help, you need to resort to heavy artillery - ammonia. The bottle is dissolved in a bucket of water, applied with a sprayer over the feather. As a result of processing, burns remain, but pests disappear. Unfortunately, if a massive raid is made on your garden, folk remedies may be powerless.

Fungal diseases and control methods

Yellow onion feathers can talk about another fungal disease - bottom rot. You can find it by pulling out one plant and examining its spine. In the stage of development of the disease, a light white coating, and if the fungus rampages on the site, the bulbs are softened and covered with gray rot. The reason is thickened plantings, flooding or any waterlogging of the soil. If such a phenomenon has already occurred on the site, in next years onions should be planted as far away from this zone as possible. Do not use seed from an infected crop, but before new fit process the sevok in a weak solution of potassium permanganate or alcohol. Water the bed moderately, arrange drainage or drain excess rainwater.

What to do so that the onion never turns yellow?

There are a number of proven, biologically based methods that will help you grow large, healthy onions without much difficulty.

Every year, change the planting site of all crops, including onions. This will not save you from weather disasters, but this measure is very effective from the lack of nutrients in the soil and from wintering pests.
Apply on site mixed landings. Onions and carrots are proven neighbors that protect each other from pests. Onions planted around currants are also protected from insects by the tart smell of the bush. The plant feels good in strawberries and next to basil, and peas, which are able to draw nitrogen from the deep layers of the soil, abundantly supply growing onion heads with it.
Mulching all free land between the bulbs with dry and green grass, which also has its own smell and confuses pests. In addition, the yellowing of onion feathers sometimes causes the bear to walk near the roots. But this pest does not tolerate shady areas, and vegetable mulch creates a permanent shady and wet effect. When temperatures change, the organic carpet keeps the onion beds from freezing or drying out.

Onions dry in July - what to do?

By mid-July, the onion should lie down and dry completely. It's harvest time. The last two weeks, watering completely stops. If weather forecasters predict rains, it is necessary to have time to collect and dry the crop before the moment of precipitation. Having pulled the heads out of the ground, it is advisable to leave them in the garden for another 2-3 days. At high humidity lay in a well-ventilated area, loosely pressing against each other in one layer. After complete drying, cut off the roots with scissors without damaging the bottom, and leave the top 3-5 cm. In this form, the crop can be stored for storage.

If the calendar is August-September, then the question of why the onion turns yellow in the garden should not bother summer residents. This is a natural process, the crop is ripe and will soon need to be harvested.

But if now is the beginning of summer and the onion is turning yellow, then you need to decide what to water to cope with this problem. After all, such a process is a serious problem that can leave gardeners without a crop.

How to process the onion if it turns yellow due to pests?

First you need to decide who is in it. It could be:

onion fly;
onion secretive proboscis and thrips;
stem nematode;
onion moth.

A general tip to reduce the impact of all pests is that it should not be planted in the same bed every year. The minimum time that it is desirable to withstand a bed without onions is 4 years. Then it is more likely that it will not turn yellow due to pests remaining in the soil.

What to do so that the onion does not turn yellow due to the reproduction of the onion fly? Here are some recommendations:

plant it as early as possible so that by the time it appears, the plants have time to gain strength;
choose a bed close to carrots;
during dandelion flowering, feed the onion with a mixture of wood ash, pepper and tobacco dust.

If this pest is wound up and the onion turns yellow, then there are some folk remedies to the question of what to water. For example, watering saline solution. Salt is required 200 g per 10 liters of water. To improve the effect, you can add a little to this mixture. ammonia(2 tablespoons). With this solution, you need to water the bed so that the water gets only on the bulb. It should not be spent on the free soil of the bed and not fall on the feather. You can also water the beds with a solution of urea.

Careful cleaning of the remnants of the feather will help to rid the garden of the onion secretive trunk and moths. Plus, deep digging of the beds is required before the frost.

From the yellowing of onions due to stem nematodes and thrips, recovery will help before planting in hot water for 6-10 minutes. Only the temperature should be around 45 degrees. Pests will be repelled by calendula and marigolds sown in the aisle of beds with onions.

How to water the onion so that the feather does not turn yellow due to diseases?

One of the reasons is fungal diseases. In order to prevent the onion from turning yellow, the sets must be warmed up before planting. It will be enough for 12 hours under the rays of the hot sun or to create a temperature of 30 degrees C artificially.

Another tip on how to feed onions so that they do not turn yellow is to water with a solution of copper oxychloride. You will need to add a tablespoon of the drug and the same amount of liquid soap to a bucket of water.

To prevent yellowing of the feather due to bottom rot, you will need to choose the right place to plant. It should not be at the bottom.

The tips of the onion in the garden turn yellow from improper care. What to do?

Follow simple rules:

it is worth watering the onion with water, which was collected in advance and managed to warm up to air temperature;
water should flow under the root, if you need to water the plants from above, then use a watering can with a net so as not to expose the bulbs;
during watering, onions are recommended to be fed with mineral supplements;
stop watering 30-45 days before harvest.

Onion feather turns yellow due to weather conditions

If the summer turned out to be hot, then you need to pour the plants as soon as the bed begins to dry out. The soil with growing onions should be moist at a depth of one centimeter. This can be checked by poking the ground with your finger.

And if the climate is such that all the rains are flooded? Only a greenhouse will help. She will cover the bow from rainwater.

The last reason for yellowing onions: lack of nitrogen

There are such situations that there are no pests and diseases, watering regularly, but for some reason the onion turns yellow in the garden. What to do in such a situation? Check nitrogen content. You can save the onion only if you feed it with nitrogen-containing fertilizer. It can be manure or litter, as well as specially designed fertilizer complexes.

Without growing onions, not a single summer season passes for an avid gardener. However, this plant, like all others, is not protected from pest attacks and the occurrence of various problems. One of these is the yellowing of the onion, which signals a deterioration in its condition. To return the bow to natural green color, it is necessary to make an accurate diagnosis of his disease.

Wrong watering

Onion is a very demanding plant in terms of the frequency and degree of watering, so the reason for its yellowing may be hidden in insufficient moisture. Especially the culture needs moisture in the first two months after planting, since this time runs active growth of all important parts. Onions must be moistened before and after weeding. It is best to irrigate in furrows built between the rows, which accelerates its growth and protects it from damage. If watering from above on the plant, then it is worth doing this using a mesh watering can so as not to wash out the ground and prevent the bulb from being exposed.

Determining the degree of soil moisture is quite simple. To do this, you need to pierce the ground with your finger, if the soil is dry to the level of the first phalanx, then you can safely water the plant, if not, then wait a little with watering. Water onions should be plentiful so that the water can moisten the roots well. A couple of months before harvesting, watering should be completely stopped. In an effort to prevent the soil from drying out, it is important not to flood the onion, as excess moisture can cause the spread of fungal diseases and microbes.

bottom rot

Yellowing of onions in the garden can occur due to the appearance of such an unpleasant disease as bottom rot. Infected onions can quickly lose leaves that fall off the top. The main part of the roots deteriorates and rots, and the bulb acquires a painful yellow color.

It is very difficult to cope with such an unpleasant phenomenon and the best remedy combat is prevention. It is not recommended to plant onions in beds where onions also grew before, since diseases in the soil will easily be transmitted to the new generation, and poor soil from the previous planting will weaken the newly planted plants. Onions should be planted on the same bed only after 3-4 years. It is best to choose varieties for planting that are highly resistant to bottom rot. Infected plants should be removed immediately before they have infected all the onion beds. Before planting, seedlings must be immersed in a special disinfectant solution; a fungicide is well suited for this purpose.

onion fly

The source of infection is an insect appearance resembling a fly. It has a gray-yellow color, in the middle of the body there is a dark strip, reaching no more than 7 mm in length. The insect lays whitish eggs, which mature after a week and begin to feed on the plant, worsening its condition and causing yellowing of the leaves. Approximately at the end of May, it begins its vigorous activity, and its eggs are buried under the soil or under the first dry scales. An insect can lay up to 10 larvae near a plant. After some time, a cavity forms in the onion, in which pests hide. Interestingly, several generations of onion flies can change over the summer, so if a disease is detected, urgent measures must be taken.

How to get rid of this dangerous pest Luke? First of all, infected plants should be destroyed quickly and in a timely manner. To avoid laying larvae, onions are recommended to be planted as early as possible. Plowing the soil is best done in the fall. It is useful to sprinkle the earth with onion beds wood ash and peat, ground charcoal is also suitable.

There is one more interesting advice pest control, place a carrot bed next to the onion, the smell of which will become an obstacle to insects. In the phase of active plant growth, it is recommended to apply such products as Mukhoed and Medvetoks to the soil. To save environmental cleanliness onions, agronomists do not recommend using chemicals in pest control.

Onion Stalker

This pest infects only some varieties of onions - onions, chives and batun. Outwardly, the insect looks like a beetle of a bright dark color, on the back of which there are many tiny scales. The beetle is very tiny maximum length 2.5 m. The onion pest eats holes in the leaves of the plant, after a while whitish round-shaped spots form in this place. The secretive trunk poses the greatest danger for the first shoots. The delayed larvae, after maturation, gnaw long and barely noticeable stripes in the stem of the culture. Damage causes drying, yellowing and curling of the leaves.

The pest hibernates in the upper soil layer, feeding on unharvested bulbs in winter, and then moving on to fresh crops. Eggs develop quickly in just a couple of weeks, and in the second half of summer a new generation of secretive proboscis appears.

nitrogen deficiency

Another reason for the yellowing of onion leaves is the low nitrogen content in the soil. This is one of the most common causes of bulbous feather discoloration. The situation can be corrected by adding nitrogen fertilizers. For this, various organic and mineral-organic top dressings are excellent.

fungal diseases

With such diseases, the onion seems to be covered with rust, the feather of the plant is affected by yellow dots, and convex formations appear, which after a while cause the leaves to fall off and die. To combat fungi, you should warm up the onions before planting, do not neglect crop rotation, spray the plant in the active growth phase with a special solution - 1 tbsp per 10 liters of water. copper oxychloride and 1 tbsp. l. soap. Then, a week after the spraying procedure, the onion is treated with Hom according to the instructions.
