Never fertilize onions with this: what can ruin the harvest
Onions are among the vegetables whose entire parts are consumed. Therefore, it is crucial that the entire plant remains healthy and nutrient-dense. However, an incorrect approach to fertilizing onions can spoil at least one of its parts - the greens or the bulb itself, or even the entire crop.
OBOZREVATEL has figured out how not to make a mistake when choosing fertilizers for onions and discusses bad and good options.
Bad and dangerous fertilizers
Various herbal decoctions and infusions will not benefit the vegetable. Nettle is a particularly bad choice, as it enhances the growth of greens too much and will not be useful for the bulbs.
An excess of nitrogen fertilizer spoils the entire plant at once. It makes green onions brittle and less juicy, and the underground part loses its flavor.
Humus is a bad choice when planting onions in the ground. It is not able to provide the vegetable with enough potassium, phosphorus, and other nutrients. As a result, the bulbs will grow small and will not store well. Therefore, it is recommended to apply humus to the soil in advance - 1-2 months before planting.
Ammonia is another unsuccessful substance for treating onions. It burns the entire underground part of the plant, which can irreversibly damage the crop.
What fertilizers will benefit onions
You can obtain good mineral fertilizers for the vegetable by mixing urea (10 grams), superphosphate (30 grams), and potassium chloride (5 grams) in a bucket of water. This amount should be sufficient for a square meter of the garden. It is good to apply this fertilizer at an early stage of plant development, as well as at the end of June.
Two weeks after the first application of the fertilizer described in the previous paragraph, it is beneficial to feed the onions with nitrophoska. For 10 liters of water, you will need 2 tablespoons of the substance.
You can also create dry fertilizers based on ash. For two cups of dry mass, add one teaspoon of red pepper and 1 teaspoon of tobacco dust. This mixture is evenly distributed over the onion bed.
