Onion is probably the most popular of the cultures, because no one can do without it. garden plot. And this is understandable, because in addition to their taste, onions have a huge number of useful properties.
But even with such a seemingly simple culture, problems often arise. One of the most common situations is when green onion turns yellow. If you do not pay attention to this in time and do not start a fight, then the harvest can be lost. This problem is especially relevant for gardeners growing onions for sale.

Causes of yellowing green onions
To deal with the problem of yellowing onion feather need to find out why this is happening. And there are plenty of reasons.
Reason one: natural phenomenon. In August, the onions are already completely ready for harvest, so the green feathers begin to fade, signaling that the bulbs themselves are already ripe and it's time to remove them from the garden. This is the only reason you shouldn't worry about.
Reason two: pests. There are several. Absolutely for all types of onions: both for ordinary onions and for its more noble counterparts (leek, chives, shallots ...) the larvae do the most harm onion fly. At the end of May, females lay their eggs either in the ground near the plant, or between green feathers. After a week, the hatched larvae make their way inside the bulb. Feeding on its pulp, they lead to the fact that at first the feathers turn yellow, and then the plant dies altogether.


In order to prevent yellowing, you can use a few tricks.
1. If you plant the bow as early as possible, then even before the flies appear, it will gain the necessary strength.
2. There should not be a permanent place for planting onions.
3. Since the onion fly cannot stand the smell of carrots, you can make beds with these crops next to each other or alternate them.
4. Since mid-May, you need to start using repellents. For example, dust each square meter of planting with the following mixture: mix a teaspoon of ground pepper and tobacco dust with 200 grams of ash. Then the soil needs to be loosened.

5. When flies appear, onions can be treated with one of the drugs: Confidor, Leptocid, Mospilan, Nurell-D.

If preventive measures were not carried out and the larvae had already damaged the bulb, as a result of which the plantings began to disappear, it was necessary to start the fight. To get rid of this pest, you need to take 30 g of Baduzin, mix it with 500 g of sand and add this mixture to the soil (a calculation is given for 15 square meters).
You can also use the drug Creocid PRO, which needs to be sprayed on the affected plants.
But you can solve the problem with folk remedies: dilute 200 g of salt in a bucket of water and pour the onion with this solution. You should not do this if the feather has not yet grown to 8 cm and should not be allowed to fall on the green part of the plant. It is also not necessary to abuse this method, as this can cause soil salinity, and due to excess sodium and chlorine, plants will grow poorly and disappear.
Onion leaves feed on the beetle secretive proboscis and its faces, which eat out longitudinal passages in feathers. Therefore, green onions begin to turn yellow.

To prevent the appearance of this pest, it is necessary to completely clean the beds after harvesting, because the beetle hibernates in the remains of onions; before frost, dig deep into the soil; loosen the ground between the beds, adding repellents to it (mustard powder is suitable for this, ground pepper or wood ash).
Karbofos is suitable for fighting the bug. One package of the drug, diluted in a bucket of water, is enough to process 10 square meters of planting.
Another fan of eating onions is the onion nematode. This small worm, similar to a thread, feeds on the sap of the plant, which is why the green onion begins to turn yellow and dry out, and the bulb itself, as it were, “turns out” outward. This is due to the fact that the rudiments begin to grow through the cracks formed. If you do not fight these pests, then the earth will be infected for decades.

As a preventive measure, you can use the following tips:
1. Onions can be planted in the same place at least after four years.
2. Before sowing onions, sevok should be dipped in water for 5 minutes at a temperature of 45 degrees or for 25 minutes in a saline solution (a tablespoon per liter of water).
3. Plant marigolds or calendula between the rows of onions. A tincture of marigolds can be watered directly to the plants.

Onion (tobacco) thrips suck the juice from the plant, so the leaves turn yellow and dry out. As a preventive measure, sevok should be dipped in water at a temperature of 45 degrees for 10 minutes and then immersed in cold water. Planting material can be sprayed with Confidor (1 ml of solution per bucket of water) or Spark (one tablet per bucket of water). This is enough to process one hundred acres of land.

It is worth noting that these pests can get along with each other and infect the plant at the same time, so it is better to carry out comprehensive prevention.

Reason three: illness. For example, rust, which causes the appearance of raised dots of yellow. The leaves eventually turn black and begin to fall off. To prevent the development of this disease, the seedlings need to be “warmed up” at 40 degrees for 12 hours; spray mature plant copper oxychloride solution (add a tablespoon of the drug to a bucket of water and liquid soap), and a week later with a solution of "Homa".

The next disease bacterial rot that affects the bulbs. Brown streaks appear between the scales, which is why the feathers turn yellow. For prevention, the land is treated with Hom before planting (a bucket of water with 40 g of the drug is enough for 20 square meters).

Almost all types of onions are susceptible to bottom rot. The cause of the disease is Fusarium fungi that infect the bulb during the growing season. To avoid infection, it is necessary to plant onions on small hills in order to avoid stagnant water, to carry out preventive measures (everything is suitable as for preventing the appearance of an onion fly).

Reason four: lack of nitrogen. This is the most common reason why green onions turn yellow. What to do? Nitrogen-containing fertilizers must be regularly applied to the soil.

Reason five: improper care, in particular - improper watering. Drip irrigation is the ideal method of irrigation. Each onion variety has its own requirements for watering, but the universal rules are: when the onion begins to take root and grows, it must be watered abundantly, in the morning and at least 2 times a week (except for mulched soils). Water should not be cold (18-25 degrees) and soft (hard water can be softened with special equipment).

Reason six:weather. Drought, as well as excessive humidity, negatively affects green onions, so building a greenhouse is ideal.

How to store green onions

Growing green onions is only half the battle. After all, it must also be preserved, especially if it is a source of income.


The first rule: sort out the feathers, removing all the spoiled ones.
The second rule: do not wash the feathers before storage or dry them thoroughly after washing paper towel.
The third rule: put dry feathers in a bag, tie it up and make a few holes for ventilation. If the onion has been uprooted, then they must be wrapped in a cloth moistened with water and dry paper.
If you follow these rules, then cut onion feathers will remain juicy green for about 3 weeks.

You can not plant turnips and turnips, parsnips and turnips, scorzonera and radishes, but there are onion plantings in every garden. Onions are added to great amount dishes, preparations for the winter, soups, roasts and salads are inconceivable without it. However, when growing onions, gardeners often face such a problem as yellowing of the tips of the onions.

Such a phenomenon may occur different reasons. As a rule, only the tips turn yellow at first, then the yellowness spreads to the entire feather, good harvest you can’t get from such a bow.

It is important to know the reasons in order to take action in time, and even better - to prevent yellowing of onion greens.

For planting onions, the soil must be prepared thoroughly, the vegetable is demanding on its composition:

• Before planting, half a bucket of ash is added to any soil per garden bed, and on acid soils, a whole bucket is added. Acidic soil can affect the yellowish color of the feather;
• The beds should be fertile, make two buckets of compost or humus per bed. On poor soils, the onion feather will begin to turn yellow soon after the sprouts appear;
• Add a glass of bone meal and ¼ cup of complex mineral fertilizer to the ground.

Onion yellowing can also be caused by pests. As a rule, this is a sudden yellowing, when only a few days pass from the appearance of the first signs of yellowness to the complete withering of the tops.

Causes disease and onion rot. For its prevention, water the beds with phytosporin and make river sand. Monitor watering, do not allow excessive moisture.

To identify the cause of the yellowing of the tips, dig a few pieces of onion into different places beds and carefully inspect.

Prevention of yellowing of the feather in onions

To prevent yellowing of the onion feather, cook fertile soil with the addition of ash, its composition should be neutral, not acidic.

! Carefully inspect planting material before boarding. Remove rotten, soft, or moldy onions.

At autumn planting onions are kept for 2-3 weeks in the warmest place, this is called warming up. In the conditions of an apartment, the onions are laid out in a single layer in a box and placed on a battery; in the country, the box is placed next to the stove.

At spring planting also keep the onion warm, and then carry out the mandatory processing, namely:

• Dip the onions for half an hour in a solution of any complex fertilizer;
• The material is washed and dipped in a dark solution of potassium permanganate for 20 minutes;
• Onions are pulled out of the solution and begin to plant. After potassium permanganate, it is not washed.

Plant onions according to garden classics, alternating several rows of onions with a row of carrots. There will be a double benefit from such a combination, neither onion nor carrot flies will be without any effort on your part, and spraying from these pests will not be needed.

To avoid damage to the onion feather, it is important to carry out the first nitrogen fertilization in a timely manner. After the snow melts, urea granules are scattered on the beds with onions.

The onion feather turns yellow: we fight pests

Underground pests damage the roots of the onion, as a result, the feather also turns yellow. To reduce the amount of wireworm, before planting the onion, the bed is sown with green manure. The wireworm especially does not like mustard. Before flowering, it is embedded in the soil, green manure is sown both in the spring and after picking onions.

To scare away the wireworm and other pests, naphthalene or tobacco is added when planting in the garden.

If pests are found on onion greens, they are sprayed with karbofos, actara or actellik no later than a couple of weeks before harvesting.

Even the most experienced onion grower is faced with the problem when the tips of the onion turn yellow and subsequently dry. Sometimes these are point phenomena, on square meter one or two bulbs, means that rotten bulbs or weak ones, with insufficient nutrition, got into the onion planting material. Such bulbs are usually removed and discarded. But it is much worse when you enter the greenhouse and watch how the onion feather gradually turns yellow in the beds. And then panic immediately seizes, by the way, not only a beginner but also an experienced onion grower, since it will no longer be possible to get rid of this onion disease, and the time and labor spent are reduced to minimal earnings from this batch of onions. It's a shame indeed. But it’s better to figure out why the feathers on the bow turn yellow and what to do in such a situation.

The tips of the onion turn yellow and why this happens

I am not writing this post by hearsay. I had a situation when the tips of the onion turn yellow and, and panic also seized me and I could not understand why the onion feathers turn yellow and what to do. Therefore, I perfectly understand the people who are faced with this misfortune. There is one “trick” here, in the descriptions of growing onions in the winter in a greenhouse. All resources claim that onions are cold-resistant crops and are not afraid of short-term frosts. Yes, I agree with this, but where are the clarifications that onions and onion feathers are the same thing? That's right - no. So here Dear friends, I propose to forget about the onion turnip and perceive the forcing of the feather as a separate culture. Onion turnip for us onion growers exists only at the stage of choosing high-quality planting material. Further, it has no interest for us. She doesn't even need feeding. Everything we work on over the next month is a pen. If there are those who disagree, please do not scold me strictly, these are my personal observations and in no case do I want to convince anyone and persuade them to do something.
Now in order.

Onion feather turns yellow

It happens that my onion feather turns yellow. As I already wrote in the article “about the blog”, I have air heating, and where it is installed there is always firewood and constant temperature control. It is necessary to heat the stove in winter from the evening until almost noon next day. End of November, ideal weather for our region +15-18. I plant two tons of onions in the hope of driving out the feather by the new year and making good money on my favorite pastime. The process is going well, the green onion grows strong, dark green handsome, the onion feather does not turn yellow. By mid-December (I don’t drown), it reaches a height of 25 cm. 10 days before the new year, the weather begins to deteriorate and the cold is abnormal for our climate at this time of the year. Well, nothing, onions are frost-resistant culture, I’ll drown a little and everything will be fine - I think. And this despite the fact that there was only one layer of film in the greenhouse, you can probably imagine already and smile. But I was inexperienced and did not pay attention to it. And then the morning frosts began to -16, in the greenhouse it’s good, comfortable, the temperature is +25, what else is needed for happiness. I checked the stove, there is a draft, I will heat it at night. And so he did. In the morning I go into the greenhouse, and there -2, on the thermometer that lies on the garden bed, a confident 0 (zero). Yeah, it is necessary to cover the second layer of the film - a thought flew through my mind - fortunately, the onion is not afraid of frost. Another day, again warm, the second layer of the film is stretched, everything is gorgeous. Night, -15, I drown, until the new year a week, the calculator in my head counts the income. The next morning I go in and see that onion feathers turn yellow on some of the bulbs. Yellowness two or three centimeters. Immediately the thought powdery mildew visited me. I run to the Internet to look for up-to-date information on why the tips of the onion turn yellow.

Photo: Yellow onion tips

And here everything is just “super”, on each site there are articles written off from each other and redone in their own way about what to do and how to pour onions if the tips turn yellow. I understand this now, at the same time I took seriously the articles about the onion fly and recommendations for combating it. Terrified and panicked, I swabbed the saline solution as described in the recommendations, poured onions and calmed down. I think she (the onion fly) will not have time to destroy everything in the remaining days. By the way, according to all Internet data, only the onion fly and various insects are to blame for the drying of the tips of the onion, more reasons and cannot be. Funny.

And again morning, and again horror, the onion feathers turn completely yellow all over the garden. And at yellowed yesterday, the tips began to dry.

Further, you already understand that I did not receive income, with grief I recaptured the finances invested in planting material in half, and I even had to throw green onions on a compost heap. It was my first experience and the first winter, after disappointment and wasted time and effort, not only my own but also those close to me who helped plant onions, I wanted to quit this occupation. But then I decided to analyze the situation, work on the mistakes, find out why the onion feathers turn yellow and continue growing green onions "resting their horns on the idea." Many beginners give up after the first defeat because they do not understand what to do next. Don't do it, everything will work out, just believe and work.

As it is already clear, the reason was not in, but the tips of the onion feather simply froze and the tissues began to die off - turn yellow. If I were smarter at that time, I knew that the onion fly sleeps in winter and it only works in summer.

The onion feather turns yellow and what to do

After that incident, I constantly take measures and forgot about such a misfortune - when the tips of the onion turn yellow. How I did it: more vigilant control of the weather forecast, for the week ahead, with the threat of a sharp drop in temperature in the greenhouse, I immediately stretch the second layer of film. I sheathe the northern wall of the greenhouse to the ceiling with 1 cm foil insulation. Along the entire perimeter, one meter from the ground in the walls between the layers of the film, I insert a 5 cm thick foam. oven all night with full temperature control. When everything works out, I calmly continue to work. Nothing complicated, just take action in a timely manner. Whatever extreme situations you have not happened, remember, you do not have the right to lower the temperature in the greenhouse below +3. In support of my arguments, I conducted an experiment, after cutting the onion in the cold, I left one square and stopped heating. The temperature on the first day in the morning was +5, the onion was excellent, on the second day in the morning it was already +3 (the greenhouse was cooling down) the onion grew further, on the third day it was 0 (zero) degrees and the onion did it again, on the fourth day -2 and almost instantly , within a day and a half, the feathers on the onion began to turn yellow. I really hope that this sore will bypass you, chop it off at the root.

It was I who described the problem of why the tips of the onion turn yellow in winter time and what to do for prevention if the onion feather turns yellow. But I also encountered it in the summer - this is another problem that requires great efforts to prevent.
