Why do onions turn yellow?

Onions are an irreplaceable crop that no garden can do without. In spring, green feathers become the basis of aromatic salads. People stock up on white bulbs for the whole winter. This is an excellent addition to any dish, and even a medicine that kills harmful infections. But sometimes there are problems with growing onions. For example, yellowing.

If this happens in August-September, then no one is worried, of course. This is just a sign of ripe bulbs that are time to be pulled out of the ground. But why do onions turn yellow when they still have time to grow? There may be several reasons. Perhaps the culprit is pests, or rather the onion fly. Its larvae settle in the bulb and liquefy it. As a result, the feather turns yellow and withers. It is not difficult to detect this parasite. To escape flies, gardeners alternate planting onions, place the beds near carrot beds, and water the plants with a solution of table salt (half a glass per 10 liters of water). There are also special preparations that repel this insect.

Another reason is nitrogen deficiency in the soil. This happens if there is not enough moisture or after heavy rains, when nitrogen along with water goes deeper into the ground. In this case, you should resort to fertilizers containing this microelement. For example, urea or infusion of manure or another complex remedy.

Onions also love loose soil, rare and abundant watering. Excess moisture is fraught with phytoepidemic. It’s better not to rush, 4-6 times a month is enough. This popular crop may also have other diseases, fungi, rot, etc.Almost all disorders of normal growth are accompanied by yellowing of the feathers.
