Onions are most often attacked by the onion fly, which cannot stand one vegetable.
To avoid having to deal with pests, it is better to plan the area in advance.
Experienced gardeners have noticed that the harvest is larger and there are fewer pests if you select a good “neighbor” for your plants.
The fewer pests, the greater the chance of getting an enviable harvest. Some gardeners use chemicals to destroy insects, including onion flies.
But such a step is taken only in extreme cases. First of all, hopes are placed on the successful proximity of onions and carrots.
These crops mainly suffer from carrot and onion flies. But the gardener's benefit is that the insects do not tolerate each other. Therefore, a kind of cross-protection works without a drop of chemicals.
Onions are not so friendly with other plants, so it is worth leaving a little more distance between crops than usual.
