Often yellow onions from the fact that it encroached pests. Among the leaders of the damage:

Therefore, the cultivation of green onions require preventive measures for the prevention and timely treatment.

Why yellow onions?

There are two other reasons why the feather bow may turn yellow:

1. Lack of nitrogen. This substance is "responsible" for the build-up of green plant mass. In our case - onion pen. The plant is starving, and because of this changes the color. Recognize nitrogen starvation can on the following grounds:

• yellowing begins with the tip of the pen;
• color fades gradually;
• the tips of the feathers twist;
• spots may appear;

• often suffer from a bulb in the earth shrinks and changes shape.

Fortunately, you can solve the problem very quickly: need only 2 fertilization, and after 10 days the situation is normalized.

2. Drought. If you set the hot weather with occasional rainfall, the onions can respond to this urgent yellowing. As a rule, it goes hand in hand with desiccation. Feathers are like narrow cloth, in advanced cases - stalk weakens and bends to the ground. This problem is also easily solved: a sufficient watering.
