How and how to water green onions so that the feathers do not turn yellow
How to water the onion so that it does not turn yellow? The answer to this question must be sought in the conditions of planting and caring for the plant, in the root cause of the disease of green arrows.
How to pour onions so that they do not turn yellow
No vegetable garden is complete without bulbs and green succulent onion arrows. Caring for the plant is simple, and even a novice gardener knows about what to water the culture. Onions are rarely exposed to diseases and do not need constant watering, but sometimes even with an unpretentious culture, trouble happens.
Onions turn yellow, what should I do?
A popular and healthy vegetable - an integral "inhabitant" of any vegetable garden. On the garden bed of a skilled housewife, several varieties grow at once, which do not have to be watered every day. Easy maintenance and consistent yields are two main reasons why onions are planted in large and small areas. A root vegetable and a succulent feather are valuable. Watering is carried out together with neighboring crops. You can feed the onion with the simplest homemade fertilizer. Good nutrition will protect the crop from various pests and diseases. Fertilizer is prepared from humus and peat (sometimes fertile soil is added). It is best to water the fertilized soil out of turn, so that the nutrients quickly penetrate the root crop. Proper care and homemade folk remedies will ensure a healthy harvest for every gardener.
If the root crop turns yellow right away in the garden, you should find out what the reason is. The feather dries up quickly and loses juices. It is almost impossible to save a wilting plant. Even if you water a dry feather, at best, new arrows will grow in its place, or the bulb will rot and never recover. It is very difficult to feed a crop with pests, so it is necessary to get rid of the parasites before they infect neighboring plants. It is not enough just to water the root crop, it must be mulched. For these purposes, folk remedies are suitable that eliminate the cause of the disease and save the entire yellowed crop.
The reason for the yellowing of onions
After planting in open ground, it is better to water the bulbs once a week, but up to five times a month. The culture does not need abundant watering, and an excessive amount of moisture can harm both stems and root crops. If the bulbous stem did not turn yellow immediately, but gradually, problems arose in the root system. Environmental problems lead to rapid drying of arrows.
Watering the onion so that its green growth does not turn yellow should be done according to a previously created scheme. The plants themselves are unpretentious and can withstand even low temperatures. The culture is planted in early spring in open ground or in a greenhouse in winter. Onions are a source of nutrients and vitamins, as well as a natural antioxidant. People say: "If the onion turned yellow immediately after planting, there is no need to wait for the harvest." Watering such bulbs is simply pointless.
Folk remedies are still used to treat greenery from pests.In those cases when only the bulbous stem turned yellow, and the rest of the seasonal vegetables and fruits remained healthy, the cause was looked for in pests.
You can make special trenches on the garden bed if there are heavy torrential rains, because rot is the second most common reason that the onion turned yellow sharply. Additional watering of such plants is not worth it. Reasons why the disease spreads to sevok, bulbs and feathers:
- onion fly;
- excessive watering;
- small pests;
- lack of nutrients and nitrogen;
- decay of the root crop, which depletes the feather;
- constant bad weather in summer.
It is not enough to water the plants, they should be properly taken care of. Watering that is not organized will harm the onion rather than help. Succulent feathers and bulbs will grow in the garden only if the gardener has shown skill and perseverance in caring for all crops.
Onion fly
If the onion shoot has begun to wilt slowly, you can check the green feathers for onion fly larvae. In a garden bed where a green and tasty crop is densely planted, breeding pests are quite common. The yellowing effect appears due to the large accumulation of larvae. Timely prevention helps to prevent the reproduction of pests that lead to the death of the plant.
The leaves are an ideal environment for fly larvae, and the nutritious stems keep the eggs alive while they are growing. You can plant any kind of bulbs next to carrots, then no flies will be a problem. The smell of carrot tops in the garden drives away all onion pests.
The actions to save from the eggs, which cover all the leaves of the onion, are as follows:
- do not plant the culture twice in one place;
- do not isolate the garden bed from other plants;
- a solution of hydrochloric acid (metronidazole or spraying with water with ammonia) helps against yellowing;
- from yellowing, you can wipe the leaves with an ordinary concentrated saline solution, if other substances are not at hand.
Other types of pests include onion nematodes, flies, and lurkers. First of all, leaves and stems suffer from insects. A green onion becomes infected from just one larva or a healthy individual. Flies are brought from the environment or remain overwintering at the site of the former onion planting. From such pests, a yellow tint appears on the central part of the feather, and not on the tip. Sevok does not become infected with fly larvae at all.
It is also recommended to salt a healthy crop, the leaves of which have not yet infected the insect larvae.
The green arrow suffers from yellowing in the first weeks after planting. At this time, dormant insects appear. Pests begin to multiply actively from the first days of awakening. The water and salt makes the plants unsuitable for the onion fly. It will be possible to obtain the desired solution if the proportion is observed: two parts of water and one salt.
Lurker - a pest of greenery
The yellowing pest, the Lurker, appears on green arrows in early summer. Adults or larvae harm root crops and feathers. Insects eat bulbs and arrows piece by piece. Over time, damaged plants begin to fade, acquiring a characteristic yellowish tint. A color that indicates a pest attack is an alarm for the gardener. The constant loosening of the soil will help the culture. It is especially important to fluff the soil after heavy rains. Fertilization of the land occurs once a month, with the help of ash or peat. Dilute the fertilizer with mustard, salt and pepper. From the yellowing of the leaves to the complete destruction of the root crop, it takes no longer than 2-3 weeks. Delay on the part of a person leads to the death of the entire crop.
Folk remedies will be able to get rid of pests in a matter of days. So how to pour the onion so that it does not turn yellow if you do not want to use chemicals?
Mustard and ammonia solution
For processing plants, tinctures of tobacco, mustard and garlic are used. A small amount of ammonia is added to the prepared mixture. Such solutions are infused for 4 days. If the arrows have already turned yellow and dry (a process that could not be prevented) each day of delay can cost the gardener a harvest. The prepared mixture is brought to a boil and then cooled. This solution is used to treat feathers from nematodes or other pests.
Lack of nitrogenous substances
The lack of nitrogenous substances in the soil (in an area with a lot of groundwater) leads to rapid drying of the stems. Different cultures suffer from the disease, all nearby greenery also dries out slowly and loses color. Pale white streaks appear on the succulent leaves, the appearance of which becomes the first alarm signal for the gardener. In sprawling leaves, the edges shrink, the fruits change shape. The last stage of the disease from a lack of nitrogen is the appearance of spots on the leaves and stems, more like lichens. Such symptoms are caused by torrential rains, which wash away nutrients from the soil.
Yellowing of onions is difficult to get rid of on your own. To do this, you need to fertilize the land with nitrogenous substances. Additionally, watering the culture is not worth it.
It is also impossible to overdo it in such a matter. It will not be possible to remove the amount of nitrogen back from the soil. Once the onion arrow turns yellow, the soil around all affected plants is treated with a mixture prepared from:
- greens (any succulent grass);
- straw or any dried hay;
- weed seeds;
- waste from vegetables and fruits.
All components are thoroughly mixed into a homogeneous mixture. All soil is fertilized with a margin of several meters. The mixture is diluted with water. Even rainwater collected during heavy rains is suitable for these purposes. It is not worth diluting the prepared mixtures with salt; it is better to add more waste from vegetables, fruits or cereals to them.
Rot and torrential rains
A worm that eats root vegetables appears during periods of heavy torrential rains. Watering is temporarily stopped, and the land is constantly loosened. The upper layers of the soil serve as drainage. It is much easier to get rid of excess moisture through loosened soil. After rainstorms, the soil around the onions is fertilized, restoring the amount of nitrogen in the soil. Otherwise, the bulbs will stop growing, and the growth of feathers will slow down significantly. Rotting of root crops occurs in a few days, and after that the crop cannot be saved. It is important for the gardener not to lose fertilizer over time, otherwise all the time spent will go down the drain.
Plants rot from the rhizome, especially if watered too abundantly and too often. The stems turn yellow when the root crop is completely spoiled. Dry stems indicate spoilage of the future harvest. There is no point in saving such bulbs, so it is better to immediately dig up all the spoiled material.
Unfavorable environmental conditions
It is difficult to guess the weather, because dry summer days are replaced by torrential rains. Moisture levels can rise sharply depending on the region. Even an experienced gardener is unable to predict changes in the external environment.
Protects the bulbs with fertilizers, timely irrigation and leaf processing. The stems of the culture are washed at the beginning and at the end of the season. Before planting seedlings in the spring, the soil is pre-fertilized and saturated with moisture, nutrients and minerals.
Prevention in the garden
Preventive measures can help you anticipate the hazard and eliminate it before the entire crop is ruined. Fertilizing the soil should be done before planting nigella or other varieties of onions. As it grows, the top layers of the soil are fertilized with humus, dry hay and nitrogenous substances.
It is not difficult to buy fertilizer, but a self-made substance will save time and money. The gardener will be 100% sure of its quality and safety.
Conclusion
Watering onions is only part of caring for a plant that is not only easy to grow, but also useful for food. Diseases from which the root crop also suffers are less common, but one should prepare for them. Pests, insect parasites destroy the vegetable, it is difficult, if not impossible, to get rid of their attack. During torrential rains, the bulbs suffer and the entire rhizome slowly decays.
Washing out the nitrogenous layer occurs quite often, and it is in the interests of the gardener to worry about the problem with the soil in advance. The prepared fertilizers will help to strengthen the roots and allow you to harvest a good harvest at the end of summer. Onion crops are useful and unpretentious to care for, and planting them should not cause difficulties for humans. Any possible problems are solved without much money.
