How often should onions be watered?
One of the most popular vegetables is without a doubt the onion. This is due to the many amazing qualities that this culture possesses. First of all, it must be said about the extremely wide use in cooking - onions are added to many dishes, and both the bulbs themselves and the green part of the plants are eaten. In addition to taste, this vegetable is also valued for its healing properties, since the set of nutrients and trace elements contained in it is really impressive.
For this reason, neat beds with planted onions can be seen in almost any garden or summer cottage. This crop is suitable for growing in open ground or in a greenhouse. Many grow onions on the balcony or just on the windowsill. Despite the fact that this crop is unpretentious, and even not the most experienced gardener can grow it, it is rather difficult to get a large crop of tasty onions that will be stored for a long time. To do this, first of all, you need to understand the intricacies and features of watering this crop.
Why is it necessary to moisten the soil?
Usually, when planting any vegetable, the soil is watered. In some cases, this is done before landing, in others - after. Some agronomists advise planting onions immediately in moist soil, others advise watering the soil after the seed has entered it. In any case, the soil must be moist.So still weak roots of the plant will be able to quickly absorb all the nutrients.
Onion belongs to the genus Liliaceae, since the bulb itself is the main organ. Therefore, the plant needs moisture from the beginning of planting it into the soil until the ripening of the crop. This is especially important for the development of culture. If the soil is dry, the growing season will stop. Onion heads will not fully form, and the arrows will not grow. Even at the end of its "life" during drought, onions can slow down in development or even stop growing.
An unwatered crop will turn out very small. Therefore, experienced gardeners know that if you water the onion correctly, then its fertility will double. Of course, the intensity of watering must be calculated, given the climate in which you grow the crop. Also, do not forget that at different stages of their "life" onions require different amounts of water.
To get a healthy and rich crop of large onions, it is not enough to periodically moisten the soil. You need to know how to properly water the onion so that it does not turn yellow. This also applies to how often to water, and whether to water the plants under the root or irrigate the greens directly. Consider the answers to all important questions in more detail.
Basic Rules
In addition to observing the basic rules of agricultural technology, you need to regularly water the beds with growing onions for eight weeks. The frequency of this procedure is primarily due to the weather, since with a large amount of precipitation it is not at all necessary to water the seedlings. And, accordingly, on the contrary, when the weather is dry, the earth should be moistened often (at least a couple of times a week).Many gardeners are arguing about whether this crop should be watered when planting. There is no definite answer to this question, but there are general recommendations that will help achieve a bountiful harvest.
Planting material for growing this crop is sevok, which is a small annual bulbs. These heads are buried in the soil by about three centimeters. The soil does not need to be watered before this procedure. Moreover, when planting seedlings in dry soil, the likelihood of damage to the root system is significantly reduced. Nevertheless, in most cases, it is still necessary to irrigate after planting the onion, as this will give the planting material the nutrients and trace elements it needs.
Knowing when the onions will need to be watered again is quite simple - the beds should always be at least slightly damp. They should not remain dry even for a single day.
During the period of gaining green mass and the active development of the bulbs themselves, this crop needs large volumes of liquid. Approximately in the middle of summer, the vast majority of onion varieties stop developing heads and begin to actively accumulate sucrose and other useful substances. Thus, at this time, it is necessary to water the beds with onions much less frequently. If you stick to the usual watering schedule, then the grown bulbs will have an unpleasant taste, and you will not be able to store them for a long time.
When moistening the earth with onions growing in it, you should be guided by a number of rules from professional farmers. First of all, never water an onion with a hose pointing at a turnip. This method can severely damage tender bulbs or even knock them out of the soil.The hose can only be used with special nozzles. The water pressure must be small.
It is best to water onions early in the morning or in the evening. It is explained simply. Even though onion arrows have a rough texture, water and intense exposure to sunlight can cause burns.
When the bulbs reach about five centimeters in diameter, intensive root watering can begin. During this period, you can already water without a nozzle, but the water pressure in the hose should be reduced. The grown crop is watered by the method of introducing moisture between the rows with planted onions.
To get a truly rich harvest of tasty, large and high-quality onions, it is recommended to install a special container on the site that will be used to accumulate and store water. Most often, a simple metal tank or other similar object acts as a storage tank in summer cottages and land plots. The container is installed at the highest point of the site. Then it is filled with water from a well, well or other source and left to bask in the sun for several days.
Such water is ideal for onions and any other crops. From such moisture, they will grow better, develop faster and become less susceptible to various pathogenic bacteria and fungi. This is due to the fact that the temperature of the water heated under the sun is approximately equal to the temperature of the environment surrounding the bulbs. Therefore, they will not experience the negative effects of sudden temperature fluctuations.
Onions do not like severe drought. However, these plants just as poorly tolerate excess moisture.Under these conditions, the bulbs will begin to rot very quickly. In addition, at high humidity, various diseases develop more actively, and fungal diseases spread faster.
The most common disease that occurs with excessive watering is powdery mildew. This is a rather unpleasant disease, which entails a significant decrease in the yield. In addition, such a bow cannot be stored for a long time - in a few weeks it will simply rot.
If the land plot where onion crops are planned to be planted is too damp, then beds of sufficient height should be equipped. Also, excess moisture can be dealt with using a drainage system that will drain water from the site.
Process features
The process of watering beds with onions may not seem too complicated, but it has a number of nuances that can only be learned from personal experience or from the advice of farmers. Moreover, depending on the season, the method of cultivation, as well as the variety of the crop, the rules for watering can vary significantly.
For example, in spring, onions planted in open ground are regularly watered with a moderate amount of water. The main thing is to choose the right amount of water for irrigation in the future so that the plants do not suffer from drought or too much humidity.
At this time, it is also watered exclusively between the rows of onions, since the sprinkling method is not suitable for sprouted seedlings. Water that enters the space between the arrows of the plant inevitably leads to the formation of rot.
It is important to choose the right time for watering so that it is not too hot and the sun does not shine very brightly, since under such conditions the moisture evaporates very quickly. In addition, in this case, you can accidentally burn the plants.
Some gardeners often plant onions before winter, that is, in the autumn months. In this case, it is not recommended to water the seedlings immediately after planting, as they can germinate too quickly, which is highly undesirable when cold weather approaches. Sprouted arrows due to frost can be severely affected, to the point that the plants simply die. However, even with the threat of frost, making shelter for the beds is not very rational, because the rains at this time are not too intense. Therefore, they are unlikely to be able to sufficiently saturate the earth. For the first time, onions planted before winter are watered in the spring, when the earth is freed from the moisture accumulated in it during the winter period.
This vegetable will grow normally and develop correctly only if it receives the necessary amount of water at each stage of its development. In this case, onion dislike for excess moisture should be taken into account. Therefore, before watering the beds again, it is necessary not only to study the characteristics of the soil on the site, but also to look at the weather forecast for the next seven days. Such simple measures can prevent many unpleasant consequences (from turnip decay to the attack of various pests and diseases caused by the fungus).
To prevent the onion fly from attacking the plants, even before planting, the prepared beds can be treated with a special solution based on birch tar. To prepare this effective means of prevention, it is necessary to dilute one tablespoon of tar in ten liters of pure water. Such treatment is able to protect onion plantings from pest damage for some time.If a large amount of precipitation is observed during the period of crop growth, then the cultivation of the land with a solution of birch tar is done again.
Consider the features of crop irrigation depending on the stage of plant development. At the beginning of growth, as in other periods, watering onions has its own specifics. After the seedlings sprout, they will need quite large amounts of moisture. The approximate amount of water that the onion needs for normal development during this period is thirty liters per square meter. If the weather is dry, then the beds should be watered at intervals of five days. During the rainy season, watering stops. A good idea would be to install drip irrigation.
When ripe, young onion plants are best watered with a regular garden watering can or a hose with a nozzle. At this time, it is important to maintain a water balance and bring in enough moisture to moisten the ground to a depth of at least 10 centimeters. In the following weeks, this figure should reach twenty or even thirty centimeters. Determining whether the beds need additional watering is simple - just dig a small hole to a depth of 10 centimeters and get a handful of soil. If it falls apart after that, then most likely it's time to water the garden.
Before harvesting, onions are gradually stopped intensively watered. When the leaves begin to lay down, this means that the bulbs are completely filled and have developed completely. Most often this happens two months after planting seedlings.
Ripe bulbs should not be watered, as this negatively affects the quality of the vegetable, so beds with onions are often covered with plastic wrap in case of precipitation.
What can be used besides water?
If the onion in your garden is already mulched, then, of course, it will grow much better. But this is not enough for a good harvest. In addition to water, nutrient mixtures can be used to water onions. It can be both special preparations and organic. It all depends on the desired result and the capabilities of the gardener.
saline solution
More and more summer residents today water onions with salt water. Such watering will save the plants from pests, thereby protecting the arrows from yellowing. It must be remembered that no matter what myths go about watering with saline, it will not affect the taste and the rate of aging.
Water the onion with saline three times. The first watering is carried out when the onion arrows grow in length by five centimeters. The second and third watering - 10 days after the previous one. For such irrigation, you need to use only a watering can or a drip technique. In no case should you just pour salt on the ground and pour water on top of it.
To prepare a saline solution, you need to take a different amount of salt for each watering. For the first time, thirty grams of salt should be dissolved in one liter of water. For the second watering for the same amount of water, you need to take forty grams. And for the third, sixty grams of salt will already be needed.
After watering with saline, you need to additionally moisten the bed with warm water.
soap solution
You can water the onions with soapy water only once or twice per season. Such watering is an excellent prevention of pest invasion. To prepare such a mixture, you need to take fifty grams of laundry soap. It should be crushed and dissolved in ten liters of warm water.
Ammonia
Of course, in most cases pure ammonia is not used. It is diluted with water. Ammonia has several names, so in order to avoid confusion, they should be remembered:
- ammonia water;
- caustic ammonium;
- ammonium hydroxide;
- ammonia hydrate.
Ammonium hydroxide is dissolved with water in such a way as to obtain a twenty-five percent solution. It can be used to water onions. The same solution, but ten percent is known as ammonia. It should not be confused with ammonia, as they are different substances.
The most common ammonia fertilizer is ammonium nitrate. It is able to increase the nitrogen content in the soil, it is easily absorbed by onions. A substance similar in action is ammonia water. To prepare such a solution, you need to dilute three tablespoons of ammonia in one bucket of water.
With this solution, you need to water the onion in the evening, directly under the root, so as not to hurt the green arrows. This mixture will help to significantly reduce the chance of yellowing onion greens. Also, ammonia is a great way to deal with pests such as the onion fly.
As is clear from the above, there are a lot of rules for watering onions, but they are all simple. Their observance should not cause special difficulties.
The main thing is to strictly follow all the recommendations. Then everyone can grow a plentiful crop of onions in the open field, it is enough just to start from the specifics of the land plot and climatic conditions.
