When growing vegetables, it is important to follow the rules of crop rotation. Only with the knowledge of what can be planted after the onion or after which the onion can be planted can one get rich harvests of vegetables. After all, a plant needs nutritious soil for full development. The impoverished land that is left over from some vegetables will result in weak, small bulbs. And in the place of onion beds for the next year, it is not worth placing crops that are close in requirements to the growth conditions of this vegetable. A high incidence of vegetables, attack by pests of agricultural crops can result from improper plant rotation.
Does the earth need to rest after the bow?
Plants of the same type are not grown in the same place every year. This is due to the fact that there are no nutrients left in the garden after the onion, especially potassium. In the ground, there is an accumulation of pathogenic fungi, pest larvae. Vegetables planted next year, which are similar in nutrition to the plant, will not receive enough microelements. And the larvae of the parasites will kill them faster.
Only a competent alternation of crops after onions, a crop rotation of vegetables, will make it possible to avoid soil fatigue, and will protect against the spread of fungal and bacterial infections.
After a vegetable crop, the soil becomes with a weak alkaline reaction due to the presence of mineral fertilizers in it with a large amount of nitrogen, but a minimum of potassium. Therefore, planting leeks, shallots or nigella seeds again in these beds is not worth it. Only in rare cases is a plot left for a vegetable crop, if there is no other place. But in this case, the beds are fed with manure or compost immediately after harvesting, potash fertilizers are applied.
And the best thing after the onion is to give the soil a rest, planting the area with siderates: mustard, rye. Plants will quickly restore the nutrient balance of the soil. Annual flowers: marigolds, nasturtiums - have an excellent effect on the composition of the soil, protect trees and shrubs growing close to flying pests.
What to plant after onions?
Experienced gardeners know that correct crop rotation helps to increase vegetable yields, reduce the prevalence of fungal and viral diseases among them.
After the onion, it is advised to plant representatives of cruciferous plants: cabbage, radishes, mustard. Immediately after harvesting the heads at the end of July, the beds are sown with radishes or spinach. Peking cabbage, salad is also suitable. These plants do not deplete the soil and fit well into the crop rotation scheme.
Having planted cucumbers the next year after the vegetable, there is no doubt about their successful growth. There will be no fungi in the soil that cause vegetable rot.
Planting beans after onions is recommended. As a result of the accumulation of nitrogen in the soil, the culture feels great, enriching the soil for the following plants with nutrients.
Victoria, a garden strawberry, takes root well after a vegetable. The substances remaining in the soil after the plant disinfect the area, helping the squash and pumpkin grow.
Having removed the early varieties of plants, the summer resident plants spicy herbs - dill, celery, parsley, which have time to give greens for the winter. Therefore, for experienced gardeners, there is no question of what can be planted after the onion.
What shouldn't be grown after onions?
The onion crop leaves areas depleted in potassium after harvest. In addition, there are vegetables that cannot grow in the beds after this plant, even if the soil is saturated with nutrients.
Onions and garlic are called brothers because they are similar in properties and growing conditions. Garlic planted after a "close relative" grows poorly and is sick.
Varieties of vegetable plants also do not tolerate the composition of the soil left after a vegetable crop close to them.
I wonder if it is possible to plant cabbage for another year in place of onions. Vegetable growers consider it advisable, but in the fall they advise to feed the soil with mineral complexes, and it is better to sow the site with siderates: mustard, rapeseed.
Perfect crop rotation
To improve the quality of agricultural technology, soil fertility, and vegetable productivity by virtue of the alternation of crops on the site, or crop rotation.
Plants of the same type cannot be planted in the same place. In addition to soil fatigue, there is also the spread of pests that specialize in representatives of the same family. Therefore, it is better to return the vegetable to the site after 3-4 years.
What to plant after onions for the next year will be shown in the table
If it is not possible to follow the rules of an ideal crop rotation, you need to think about what you can plant in the garden after the onion. The planted plants must receive the trace elements they need for development, they must be protected from pests and diseases. After harvesting the ripened heads, fertilizers are applied to the soil, and in the spring the site is treated with fungicidal preparations, insecticides. Use soil disinfection with a weak solution of potassium permanganate or boiling water.
Planning combined beds
Planting different crops on the same bed improves the condition of the garden, facilitates the work of the summer resident.
But what to put together, can onions and garlic be planted close to each other? They think about it because no one will benefit from the wrong neighborhood. And the plants will wither away, and the summer resident will not receive a full harvest. So, plants with a pungent smell are not planted nearby, especially on the same bed.
You can place white cabbage next to the vegetable. Phytoncides of green feathers will help strawberries, Victoria to get rid of pests. Leek scares away butterflies from the cabbage, laying eggs on the leaves.
Plant phytoncides help potatoes stay healthy. In each vegetable garden, you can plant a seed along the edge of a potato field.
It is best to plan onions and carrots in the same garden, as vegetables help each other scare off pests: onion fly and carrot fly. It goes well with vegetables beets, watercress, radishes, cucumbers. Facing the beds with chamomile, savory will help the vegetable grow better, protect it from pathogenic microorganisms living in the soil.
After which you can plant onions?
Onions need fertile, moist soil to ripen. With relatively strong leaf growth, the vegetable has a weak root system. Therefore, the site for the plant is allocated where there is a lot of fertilizer, there are no weeds. And the acidity of the soil for the vegetable crop is selected close to neutral, when the pH is at the level of 6.5-7.5.
The best precursors for planting onions are those that require large doses of organic fertilizers. These vegetables include cucumbers, pumpkin, zucchini. Nigella grows well where tomatoes, cabbage, potatoes, beans were cultivated on loamy soils, but seasoned with organic and mineral fertilizers. Since the vegetable ripens quickly, it can be planted in areas occupied by early maturing radishes, lettuce, dill, removing the plants in June.
After harvesting the predecessor vegetables, a rotted mullein with a volume of four to six kilograms per square meter is introduced into the beds. It will also be useful to fertilize the soil with wood ash up to 300 grams. But fresh manure will lead to an increase in green mass with damage to the development of bulbs. After this embedding of fertilizers in the soil, the site is dug up.
If the alternation of planting crops was observed, then the vegetable will be protected from pests and pathogenic fungi, and in August it will give large heads.
After which it is better not to plant onions?
To get strong and large plant heads, you need to plant the seed correctly. And you can grow a vegetable only in compliance with the rules of agricultural technology and crop rotation.
Whenever you are going to plant a vegetable plant, in spring or autumn in winter, it is better not to do it in one place. The vegetable will be weak and the bulbs are small. Garlic has the same effect on the culture. Common plant pests will prevent the vegetable from developing fully.
Planting onions in the area after peppers, carrots, physalis will cause a lack of nutrition in the plant. The vegetable will be attacked by pests and will stop developing. Sage is harmful to the plant. But marigolds, nasturtium, calendula, on the contrary, will scare off an onion fly with their phytoncides.
The bulbs will grow quickly and remain strong and healthy if the vegetables are correctly positioned in the garden.
