Why it is important to process onions before planting
Although onions don't require much care and are suitable for the novice gardener, they are still susceptible to disease and pests.
Fungal infections, bacteria, and insect larvae can significantly reduce or even destroy the crop. Therefore, proper pre-plant treatment has several important functions:
- protects against infections; protects against rot;
- repels pests, especially onion flies;
- strengthens the root system, improving rooting;
- prevents sprouting, which negatively affects head formation;
- accelerates germination and increases resistance to adverse conditions.
What are effective ways to process onions before planting
1. Saline solution — a simple and reliable method
Salt is an inexpensive and effective way to disinfect onions. It not only destroys pathogens, but also repels onion flies, which can spoil future crops.

- Leave for 2-3 hours at room temperature in a ventilated place.
Important: Do not exceed the salt concentration to avoid overdrying the planting material.
