Onions, at first glance, do not require a special approach to care. But when it comes to feeding, not all popular folk recipes are suitable for it. Some of them, it would seem, help other plants, but onions will definitely not be delighted with them. Let's figure out why some fertilizers should not be used for onions, but are better left for other crops.
Yeast is often praised for its ability to saturate the soil with microorganisms, but it is not a universal fertilizer. For onions, yeast does not provide any benefit. On the contrary, they need nutrition, so this process is more like a “closed circle”, where the onion receives too little, and for its root system, yeast is an additional load.
Nettle is another very popular but completely unnecessary fertilizer for onions. It is often used as a growth stimulant, and while it can be beneficial for greens, onions, which are intended to produce bulbs, not feathers, will not appreciate such care.
Even experienced gardeners still make the mistake of overusing nitrogen. It is an essential element for many plants, but you need to be very careful with onions. If you overdo it with nitrogen, the taste of the onion will deteriorate significantly, and its feathers will become brittle and weak.
Finally, many gardeners believe that onions can be fed with ammonia, but this is not true. Ammonia is essentially ammonia, and while it may be beneficial for some plants, it is not suitable for onions. Fertilizing with ammonia can simply burn the roots and the plant will begin to rot. This is definitely not the approach to take if you want to get a healthy crop.
Onions will grow big and juicy if you give preference to fertilizers such as ammonium nitrate, ash, chicken manure, and potassium salt. Apply fertilizers on time and in the right amount, then the onions will thank you with a generous harvest. We wish you success!
