When arrow-shaped onion leaves acquire a yellowish tint, this is a bad sign.
The feathers of the garden crop must be green. Otherwise, the gardener must take immediate action.
Yellowing of the above-ground part of the plant usually indicates a deficiency of one of the important microelements - nitrogen.
One well-known pharmaceutical product will help to replenish the deficiency of this component. We are talking about ammonia.
How to Turn Ammonia into Fertilizer
You need to take a standard bucket and fill it with clean water.
Three tablespoons of ammonia should be added to the same container.
After thorough mixing you will get a good nitrogen fertilizer.
The liquid should be used for watering the garden crop at the root. It is advisable to carry out the procedure in the evening hours.
This product will not only help restore the correct color of onion feathers (by replenishing the nitrogen deficiency), but will also make the plant much less vulnerable to such a common pest as the onion fly.
As a result, there will again be a high chance of harvesting a bountiful and high-quality crop.
