It is no secret that in mixed plantings each plant has its own clearly assigned role.
Some are planted as the main ones, others as accompanying ones (they create favorable conditions for the “main ones”, protect the soil from drying out and weeds).
One of the best accompanying crops is marigolds, which, in addition to the above-mentioned functions, “slow down” the development of diseases, protect against pests, and help disinfect the soil.
Marigolds, as those in the know say, are excellent neighbors for most vegetables, including tomatoes, onions, and tomatoes.
However, do not forget that marigolds should not dominate the garden bed (they only complement the plantings).
Therefore, it is best to plant either along the perimeter of the bed or in separate patches inside it.
Let's not forget that marigolds cannot be used with all plants; they can harm some.
The fact is that the root secretions of marigolds can have a negative impact on the root systems of certain crops, such as legumes and cereals.
Some gardeners say that marigolds also suppress cabbage, radishes and a number of other plants.
