For example, if new plants appear in the garden, they must be carefully examined for aphids.

Aphids are very afraid of birds, because they will be happy to enjoy harmful insects, and to attract birds to the garden, you can simply make feeders for them, but if there are already birds in the garden, do not climb into their nests and destroy them, as birds very quickly leave the garden in this case.

Do not use too many chemicals to kill insects, because if aphids are eliminated with chemicals, more beneficial insects will die along with them, which also help eliminate harmful insects. If the plant is sufficiently fed, then the aphids are unlikely to attack it, since with a lack of nutrients, the plants become weaker and pests attack them, completely destroying the shoots and crops. If you constantly dig the soil, you can also get rid of unnecessary pests, because this will help improve the air permeability of the soil, and the plant will receive more oxygen, so the leaves will become stronger and aphids will be too tough.
