While walking around the garden, summer residents notice that the onion feathers have suddenly started to turn yellow and dry out.
They understand without fail that the plant urgently needs help. But it is important to understand what exactly the vegetable lacks.
There are three main reasons why crops suddenly start showing this symptom. You can't ignore the problem, because it can end in crop failure.
If the heat lasts for several days and there is no rain in sight, then you need to grab a watering can or hose.
In this case, you need to water the onions regularly, when the sun is least active, so as not to make the plants even worse.
Sometimes onions look bad because of thrips, weevils or onion flies. Experienced gardeners say that the problem can be avoided if you soak the bulbs before planting.
In order not to soak the harvest with chemicals, gardeners use a folk remedy. Take 1.5-2 kg of wormwood greens and pour 10 liters of water.
Infuse for 2-3 days, then strain. Spray the onions with the resulting liquid every 12-14 days.
One of the common causes of yellowing leaves is a lack of nitrogen. The macronutrient is responsible for the growth of green mass, and the health of the above-ground part of the onion is based on it.
You can feed it with a special fertilizer, including a complex one, which also contains phosphorus and potassium, or with a green infusion of weeds.
