Rules for watering onion sets after planting in open ground

For its special taste, content of nutrients, onions are widely used in cooking and folk medicine. Gardeners strive to harvest this valuable vegetable on their plots. However, growing onions from sets is not as easy as it seems. A good crop yield is facilitated by the correct watering of onions grown in the open field.

What water to water onions

The main component of an onion is its head, a bulb that requires a sufficient amount of moisture to develop. If it is not enough, the process of bulb formation will stop, which will lead to a crop failure. Therefore, periodically the onion needs watering.

It should be used with warm water with a temperature in the range of 16-18 ° C. Water of this temperature can be obtained if a storage tank (barrel) is installed on the territory of the site. Liquid can be poured into it with a hose from a water supply system or a bucket from a well. The water is left in a barrel for 1-2 days to warm up in the sun, then it can be used for watering.

The water in the barrel is heated by the sun and used for irrigation

The temperature of the water in the barrel will be about the same as the ambient temperature near the bulbs, and they will not experience the stress of sudden changes in temperature. Cold liquid causes damage to the vegetable crop by various fungi and bacteria, for example, downy mildew.

Onion watering mode

Onion sets are usually planted in early May. During the period of growth of the green mass of the onion after planting it in open ground, it is necessary to ensure that the soil on the ridge is always moist and does not dry out.

Onions need moist soil due to their shallow root system.

Lack of moisture leads to the fact that onions, like wild ones, grow bitter and small. Abundant watering will cause the vegetable to rot.

The moisture content of the soil can be checked using a thin wooden stick, a torch. For this purpose, it is stuck into the ground to a depth of about 10 cm, then the stick is pulled out. If there are soil particles on it, then the earth is wet, but when there is not enough moisture, the stick will remain dry.

Undoubtedly, the intensity of irrigation is influenced by the climate in which the crop is grown. In addition, you should be aware that at different stages of growth, onion requirements for soil moisture are not the same.

At different stages of development, onions need different degrees of moisture.

The plant needs moisture very much:

  • the first 2 weeks after planting;
  • when shoots appear, for 2-3 weeks after that, since during this period the root system begins to actively grow and develop.

However, it must be remembered that moderate watering is needed at both stages.

Table: watering onions during the growing season

When the weather is rainy after planting onions, natural precipitation may be sufficient. He will not need additional watering. The color of its feathers, which, instead of green, will acquire a pale green color, will become watery, can indicate oversaturation with moisture. The lack of moisture can be judged by the appearance of the feathers: they will turn yellow, become flatter, and the tips will dry out.

Feather tips that turn yellow and dry indicate a lack of moisture

To avoid burns from the bright sun, water the onion in the morning or evening.

In dry weather, watering is increased up to 2 times instead of one, as indicated in the table.

When to stop watering

Watering the vegetable crop is stopped 2-3 weeks before harvesting. At the time when the onion feathers begin to fall on the ground, it can be concluded that the heads have developed and matured completely. Usually, this moment comes 2 months after planting the set. Watering at this time will negatively affect the quality of the vegetable.

Watering is stopped 2-3 weeks before the onion finally lies on the ground.

We had to grow onions from both yellow and red onions for a long time. Knowing that onions do not like excessive moisture and lack of it, we almost always got a good harvest of this vegetable crop. Watering was done about once a week. When the onion lay down, it was not watered at all. Water for irrigation was taken from a barrel.

Proper planting and care of onion sets in the open field

It is quite easy to grow high-quality onion heads from sets, especially since the technology has many advantages. High productivity is noted, rapid maturation of root crops, the release of arrows happens less often than when growing with a turnip. With proper care, outdoor planting is straightforward.

It is also possible to sow seedlings in the country in the northern regions, Siberian regions and Novosibirsk. It is important to follow the sowing rules, take care of it properly and protect it from frost.

How to properly water onions in the open field: schemes, norms, how often

The most important thing when watering onions outdoors is to follow the flow chart. Let's figure out how and how often to water the onions in the garden!

The irrigation scheme depends on the stage of the plant's growing season (and it can be broken down into 3 key stages):

  • Watering after planting the bulbs... In the first month after planting onion sets, plants need a lot of moisture for normal rooting, so you need to water them often. In dry weather, the frequency of watering is once every 7 days. In hot and dry weather - even once every 5 days, and in rainy weather, you can skip the procedure. The soil is soaked to a depth of 10 centimeters. However, in no case should you abuse and fill the garden bed, otherwise the bulbs will simply rot. Maintain moderate soil moisture.

  • Watering during the period of active growth, bulb formation and weight gain... Once the bulbs are rooted and grow actively, they require slightly less moisture than when they are planted. The optimal frequency is once every 10 days, while the soil is soaked to a depth of 20-25 centimeters. More frequent watering is possible in dry weather. During this period, the soil should not dry out in the root layer.

  • Watering onions before harvesting... Shortly before harvesting onions, watering is reduced, and then stops completely:
    • Closer to the end of the growing season the frequency and rate of irrigation are gradually reducedwhile maintaining light, moderate humidity.
    • At the end of the growing season, in 2-3 weeks of harvestme, when a constriction appears on the neck of the bow (that is, it will thin out, soften), the feather will begin to lie down, then watering must be completely stopped.

Note! 2-3 weeks before harvesting, it is important not only to stop any watering, but also to protect the onions from rain (which will negatively affect the keeping quality of the bulbs or lead to decay). For example, you can cover the bed with plastic wrap.

How to water onions

For watering onions, you can use:

  • watering cans with sieve necks
  • special irrigation devices - "fountains"
  • drip irrigation system.

With artificial irrigation, it is important to carefully moisturize the soil, avoiding damage to the green mass. This will protect plants from diseases and pests, and will not inhibit the course of photosynthesis.

The planted seed plant needs moderate irrigation and timely feeding. With weak plant growth, top dressing is carried out with water with a mullein solution, mixing one part of organic matter with twelve - liquid. It is advisable to let the resulting solution brew for several hours and only after that watering. Feeding is done in cloudy weather or in the evening.

Sometimes the mullein solution is additionally enriched with ammonium nitrate, adding no more than 30 g of mineral fertilizer to the bucket. Top dressing is carried out at least once every two weeks and is done in late May and early June.

It is recommended to stop watering before harvesting for 20 days, otherwise the harvested crop will be in cracks and quickly rot.

In dry summers, the frequency of watering is at least three times a week. Onions need a lot of moisture for the growth and development of the root system. Artificial irrigation of the soil should be abundant so that the liquid penetrates to a depth of at least 15 cm.

To avoid the appearance of burns on the green mass, watering is carried out in the evenings. On average, you need 1 sq. meter ten liters of warm water. On some types of soils, after irrigation, a crust forms, which interferes with the oxygen supply of the roots. To eliminate it, the top layer of the earth is loosened.

At the beginning of growth

When growing onion crops, artificial irrigation is especially important at the beginning of summer. This should be done with warm water, since low temperatures inhibit the growth of the root system. Dry weather conditions serve as a signal for abundant watering of plants - at least 10 liters per square meter.

It is recommended to avoid the penetration of moisture into the intra-leaf space, as this leads to decay of the aerial parts of the plant. After planting, you can water the onions using a hose, filling the aisles with water. It is undesirable to make a strong pressure, as this can erode the soil and expose the bulbs. After such watering, the culture will begin to rot or be affected by pests.

Watering onion sets can be done with drip irrigation. A sufficient amount of moisture in the soil contributes to the active recruitment of green mass by plants, since it is often planted on a feather. It is allowed to water the crop with the addition of a small amount of mineral fertilizers: nitrogen, potash, phosphorus (no more than one gram per liter of water).

When growing special varieties of onions for green mass, it is recommended to monitor the height of the feathers - above 40 cm they require cutting.

When ripe

Three weeks before harvesting, you should stop watering the plants planted to obtain mature underground parts. Excessive moisture in the bulb heads will impair the taste and shorten the shelf life. Ripe bulbs can be identified by recumbent, yellowed aerial feathers.

In the open field, you can water onions planted on a feather until the very harvest. Sprinkler systems are excellent attachments for the job. They allow you to achieve the required dosage of water. If the watering pipe is placed at the top, moisture will flow down the feathers, improving the metabolic processes in the plant. Irrigation should be stopped five days before digging so that the green mass does not become covered with dirt. Excessive air humidity serves as a signal to stop irrigation.

Before harvest

The approach of harvesting onions serves as a signal to stop any watering. If, at the same time, the sky is cloudy and rain is predicted, the collection work should be completed or taken after the rain.

The crop should be removed from dry soil, otherwise drying will be significantly delayed and the risk of infection of vegetables by putrefactive bacteria increases.

Not all of the dug out bulbs can be mature, so it is recommended to subject the harvested crop to mandatory sorting. It is advisable not to store the bulbs that are not fully ripe, but to use them for cooking. Remove rotten and damaged heads from healthy products, as they can infect onions.

Watering the onion correctly is a whole science that allows you not only to increase its yield, but also to cope with many crop pests. For example, using a salt solution for watering helps protect plants from onion flies, which cause yellowing of the leaves. The salty solution does not affect the taste and ripening rate of the bulbs. It is prepared by mixing 200 g of sodium chloride (table salt) with ten liters of water.

Combining onion watering with feeding

Often, many gardeners combine watering with liquid fertilizing.

Important! However, even before liquid top dressing, it is first recommended to water (about a day or a couple of hours), and in the case of sprinkling, after top dressing, sprinkle the onion feathers with clean water.

Very often at the beginning of the growing season, onions watered with salt water (1-2 tablespoons per 10 liters of water) in order to prevent the appearance of onion flour (due to its activity, the tip of the feather turns yellow and then dries up) and scaring away other insect pests, so as not to let them lay eggs, of which then the larvae will hatch.

Many gardeners are afraid to do salt treatment for fear of salting the soil and spoiling the taste of the turnips. However, if the plants are watered with a solution of the specified concentration, then you will not cause any harm.

Note! Contrary to popular misconception, the ripening rate of onions does not increase from watering with salt.

As you can see, watering the onions is not that difficult. The main thing to remember is after landing and to a slightly lesser extent during growth and development, the soil in the garden should be barely wetand when the bulbs start to ripen and during the last 2-3 weeks before harvest - dry.
