Therefore, those who are engaged in gardening, want the onion to grow a lot, and it was big. However, it happens that even during the growth of the bulbs begin to rot, as you can guess from the yellowing and drying feathers.
In order not to be left without the necessary vegetables, it is necessary to take urgent measures. First of all, you should pull out one bulb and how to handle it. If it is soft and smells awful, it’s time to act.
Why onions rot and what to do to save the harvest
This happens due to poor quality or contaminated planting material – onion seedlings, which, in addition to spoiling the crop, can infect the soil. It should be planted where it has already been tested, and before planting, the bulbs should be treated with manganese.
The second reason is the planting of seedlings in the place where last year hostile crops grew. Onions will feel great in the ground, where previously lived potatoes, zucchini, cabbage, beets.
It is also important to remember that the onion requires proper watering. In dry summers, this should be done constantly, but only until mid-July. A month and a half before harvest, you need to gradually reduce the frequency of watering, and finally stop altogether.
Onions can also start to spoil if they are attacked by onion fly larvae. These fat short white worms devour not only the feather but also the bulb. You can protect the bulb from such a scourge if you do not plant it from year to year in the same beds, because pests tolerate winter well in the soil.
When these enemies appear, we must fight. It is necessary to mix 1 tbsp. l. tobacco dust with 2-3 liters of hot water and leave for two days. Then add another 7-8 liters of water, 1 tbsp. l. ground red pepper and laundry soap. Stir everything and pour this solution over the onions. Some use “chemistry”, but it is better to do without it.
It also happens that onions are spoiled by disease. This culture can have three diseases. Fusarium wilt is a fungal disease that affects first the feathers and then the roots. It is necessary to treat urgently, and then all the onions will be lost. Bacterial rot occurs almost before harvest if it often rains and high humidity. Cervical rot is manifested at the same time. It is difficult to recognize, so it is better to buy a quality seedling.
