Citrus fruit trees

They are very sensitive to cold and wind, they develop very well in pots, thus being able to grow them sheltered from the cold on terraces or covered, like traditional fruit trees they also suffer from diseases, for example the aphid infestation is very common. The symptom is the somewhat wrinkled leaves, which possibly will be due to the plague of this insect. If when turning the leaf we see the attached bugs, we can eliminate it with a chemical insecticide or an ecological one.
