After what crops can you plant onions?

Onions - this is the culture, without which no cost, perhaps, no vegetable garden in Russia. It is used in salads, in soups, and in hot dishes, and just like that in fresh form with boiled potatoes.Naturally, it is important that the harvest of this vegetable was at the highest level. In addition to seed preparation, proper planting, regular maintenance and periodic fertilizing, you need to carefully pick a place for the beds, which is usually done on the basis of crop rotation.

Onion is a very popular and demanded product. Although onions are considered not particularly capricious plants, for a successful harvest you will still have to follow some rules regarding planting and care. For example, the culture loves loamy soil, the acidity level of which ranges from 6.5 to 7.9, but is afraid of places where water is collected that can cause rotting of the plant. Land should also be properly loosened. When planning to plant a turnip on the open ground, it is important to ensure that the beds are sufficiently lit. In the spring, while the primary growth of the culture occurs, it should be irrigated abundantly, but when the heads begin to form, significantly reduce the volume of liquid and water the beds only during drought and too hot days. Onions are quite resistant to temperature fluctuations culture. He is not afraid of frosts, but the temperature of the soil for planting should still reach +10 degrees.

It should be recalled that onions belong to the subfamily Onion families of Amaryllis. It is grown everywhere, as a rule, for the sake of vitamin green, which strengthens the immune system. Sowing onions in the fall, the crop can be harvested in the spring, but the spring planting will also pass quickly. In Russia, most often grown variety, which has the name of the bulb. It is rich in protein, sugar, vitamin D, potassium, sodium and other useful elements.

Essential oils containing sulfur are responsible not only for the unpleasant smell, but also for antimicrobial abilities. This vegetable is very healthy. It has a beneficial effect on the digestive system, works as a diuretic and even soothes the nerves. The kidneys are also affected, as well as the intestines and oral cavity. It is not surprising that such a product is actively used in medicine. Of course, do not forget about cosmetology, and about cooking, where onions can be found in every second dish.

All gardeners should be aware of one important rule - it is impossible to plant the same crop in the same place year after year. The fact is that vegetables have a tendency to take nutrients out of the soil, so next year it may turn out to be poor and unsaturated. This will result in a decrease in the amount of the crop and the quality of the fruit of the followers, or, in general, the inability to plant any plant. To avoid such a situation, it is necessary to follow the crop rotation. Even top dressing in this case will not work - the devastated soil is restored within two or three years.

In addition, when planting the same crops on the same bed in the ground, spores of characteristic diseases and insect larvae begin to accumulate. Some of them can survive the winter without any problems, which means they can infect newcomers. The gradual accumulation of pests and diseases eventually leads to the immediate destruction of both the root system and the fruit. If after the onions in the garden there is a plant suffering from the same problems, it will be immediately infected or susceptible to attack. It turns out that you can plant only those cultures that are not afraid of them. Finally, the third argument is the possibility of allelopathy. The bottom line is that the root system of one plant will start releasing chemicals into the ground that will negatively affect the root systems of other plants - the “neighbors on the garden” or the followers.

In short, crop rotation is based on the following rules:

• Plants that are attacked by the same insects and prone to the same diseases should not be planted on the same bed;
• if the plant has ripened late, the soil will “recover” for a sufficient time. As a result, the next year you should not plant early-ripening crops;
• inefficient alternation of plants that consume similar elements from the soil;
• it is important to take into account the chemicals secreted by the root system;
• if the harvest was early harvested, in the same year one can plant a green manure on the bed, since they improve the condition of the soil.

The forerunners of the onion should be on a bed that is well lit and not hidden by a shadow. In addition, the soil should be rich in potassium and phosphorus. Then the herb itself will remain satisfied. Usually these are the same fast-growing and early-ripening plants, like the onion itself, among the most successful predecessors are peas, pumpkin, tomatoes, cabbage and green manure. The latter include phacelia, rye and mustard, cucumbers, zucchini and squash work well. Although the rules of onion turnips are planted at the end of spring, gardeners believe that planting will be extremely productive in July after picking early potatoes.

As for the plants, after which the onion can not be planted, they include garlic, cucumber, carrots and, of course, onions. Regarding garlic, it is necessary to clarify separately: it is a bad predecessor, but there is no consensus on the neighborhood issue. Some growers planted it next to the onion, so that the smell frightened off the weevils and the onion fly. Others do not run the risk of doing so, bearing in mind that both vegetables feed on the same nutrients, which can cause competition and impoverishment of the soil. If the fertilizer is not enough, the feathers will begin to turn yellow, and the fruits will become smaller. The same should be said about carrots - its neighborhood is able to protect against the appearance of onion flies.

Strawberries, cabbage, carrots, lettuce and radishes will be good neighbors. The same can be said about the planting of beets and spinach. On the contrary, beans, beans and peas will negatively affect the development of onion turnips. Surprisingly, sage and chamomile will play a similar role. Onions are advised to be planted next to coriander, beets, tomatoes, and calendula.

On the features of planting a number of onions and carrots, you will learn from the video below.

If onions are grown only in order to eat feathers, you can first sow radishes, dill or spinach, and then, after harvesting, immediately plant another crop, not waiting for the next year. After the green onions, it is recommended to plant the legumes, and onions - alternate with cucumbers and carrots. By itself, onions cannot be sent to the same bed more than three times in a row. And changing the "place of residence", it is better to send to those areas, the culture of which must be fed, and as a result the stock of nutrients remains in the soil. After onions, you can plant almost anything, as it acts as a natural disinfector of the soil. If you properly fertilize the soil, then, in fact, you can plant a crop next to any "neighbors."

As mentioned above, the future bed should be placed on a well-lit, and most importantly - aerated surface. This choice will contribute to a better development of the plant, and the prevention of fungi, and protection against rot. Ideally, the soil should have a slightly acidic or neutral environment, but in the case when the figures are not normal, the soil is fertilized with dolomite flour, lime, ash or chalk powder.

In the spring, the plot is cleaned, fed with mineral fertilizers and, if necessary, dug again. A mixture of superphosphate, potassium chloride and urea is used as feedings. The bed must be disinfected using a solution of copper sulphate. As a rule, one tablespoon is diluted in a bucket of water; with this solution, the ground will need to be watered about a week before the sowing works. Preliminary preparation deserves and sevke - this is a small onion grown from seeds. It is usually aged in a solution of potassium permanganate or copper sulfate, then dried for 20 days in a warm room, after which the heads are sent to a forty-degree temperature for strengthening. In addition, it is useful to process seeds with growth promoters.
