Briefly about soil fatigue

Each crop consumes certain substances from the soil. If you grow one crop in the garden for a long time, this will lead to depletion of the soil. Potatoes and cabbage, for example, consume potassium and nitrogen, and cabbage also consume phosphorus. Tomatoes also love phosphorus. Therefore, even planting a crop for two years in a row in one place, even with fertilization, often leads to a deterioration in the condition of the soil. The soil becomes unsuitable for growing.

In addition, there is an accumulation of pathogenic bacteria in the soil, as well as larvae of pests that specialize in this plant. For example, phytophthora spores, when released into the soil, will be vital for several years. Sowing crops in this place that are susceptible to late blight serves to stimulate soil contamination. It is very important to establish an adequate and correct turnover of crops in your garden.

Cultures also affect each other with their root and leaf secretions, or phytoncides. They can have both positive (stimulate growth) and negative (suppress development) effects. For example, if you plant rye on a garden bed for two years, then you will get rid of such a malicious weed as wheatgrass for a long time. And vice versa, planting celery with cabbage perfectly protects the latter from whites.

The accumulation of plant residues in the soil strongly affects the growth of subsequent plantings during one season, and after winter, of course, this influence is significantly weakened. The same effect is obtained with mixed cultivation of vegetables and herbs.

Alternation of cultures

What to plant after onions? After onions, it is recommended to plant carrots, beets, tomatoes, cucumbers, zucchini. This is when it comes to a full annual crop rotation.

It is advisable to draw up a plan for the garden and keep records of plantings of crops. Crop rotation rules are simple. You can not plant in one place crops of the same species, family, as they are susceptible to the same pests. Crops with early planting should not be planted after crops that require late harvest. This is due to the fact that there was no recovery in the soil in a short period of time. It is not recommended to plant crops with the same mineral composition in one place.

It makes sense to alternate crops not only according to the full annual crop rotation cycle, but also to find crops that have a short development period and can be sown in the same year after harvesting.

So, after harvesting onions, it is good to sow lettuce, spinach, Chinese cabbage in August, and radish in September. Radish just does not like the time of the "long day" and will have time to give a new crop. And lettuce and spinach are very peaceful crops that do not cause soil fatigue.

If the onion bed is large, a lot of harvest has been harvested, and radishes and lettuce are not needed in large quantities, then you still should not leave the bed bare, “without work”. Then sow some siderata or annual flowers. They will perfectly protect the garden from the sun's rays and will structure the soil. You can even throw all the seeds that remain in the storeroom and are unlikely to be in demand.

If next year it is planned to sow cruciferous plants on this bed, then in August sow phacelia, rye, oats. And if you want to set aside a garden for tomatoes or pumpkin crops, then feel free to sow cruciferous ones. Nothing decontaminates the soil from root rot like rapeseed, oil radish and mustard.

You can sow green manures randomly, you can not choose the remnants of onion roots, they will perfectly grind until spring. From above, the seeds of green fertilizers can be sprinkled with a mixture of peat and sand or mature compost.

Planning combined beds

Gardeners always want to get a big return from a small area. And this is good, since the land will be roasted by the sun for a shorter time, and we will have to cultivate a smaller area.

It is noticed that the more variety there is in the garden, the more resistant it is to pests and diseases.

And this is understandable, because in order to find its "bread", the pest will have to sniff for a long time, and there are many smells, and many smells are very frightening. See the fly-repelling benefits of combining onions and carrots here.

Planting beans, parsley, lemon balm, catnip, savory, hyssop, yarrow protect from pests in the garden. You do not need to plant them in a continuous strip, it is enough to stick scattered bushes in different parts. Remember that monoplants are more vulnerable.

Cultures of the same height and fluffiness do not get along together if planted closely. Plants of the same family also do not get along, since they consume the same elements, and they also release identical substances into the soil.

So, planting planning after onions can be not only annual, but also during one season. If you try to combine planting, then less labor will be required to care for the area of ​​the garden, fewer pests will find their "delicacies".
