In the woods and meadows they are spontaneous associations of plants and herbs who live well together. For the associations in the garden instead you need the hand of man. There are vegetables that grow better if they are close together and others that cannot be tolerated: the right assortment offers the advantages of a supportive and harmonious community, as happens in nature, especially in defense from parasites.
Vegetables can be divided into good neighbors and bad neighbors depending on what they are associations in the garden are favorable or unfavorable. The main combinations, as well as those to avoid, are the following:
Associations in the garden: good neighbors
- Tomato and parsley;
- tomato and celery;
- tomato and cabbage;
- potato and cabbage;
- potato and spinach;
- salad, radish, kohlrabi and watercress;
- carrot and leek;
- carrot and onion;
- pea and cucumber;
- pea and salad;
- strawberry and onion;
- strawberry and garlic.

The consociations they also work very well with ornamental plants, but it is above all with garden vegetables that knowledge on good neighborly relations are put into practice.
In a vegetable garden, the different types of vegetables grown should integrate both above the surface of the soil and below the ground. Without coming into conflict with either the leaves or the roots, but rather protecting each other from parasites.
It is precisely in the protection from parasites that one can see the greatest positive effects of associations in the garden. This is because some plants emit substances that have a repulsive action against insects harmful to other species.
An example is the association between carrot and onion. The carrot fly, whose larva devours the roots, is repelled by the smell of onions and no longer lays its eggs on the carrot's collar. Similarly, the onion fly, whose larvae enter the pulp of this vegetable and quickly turn it into a rotten, foul-smelling mass, avoids the a the flower beds in which carrots grow.
A phenomenon similar to that between carrot and onion occurs in association between leek and carrot. Here are some associations that perform a repellent action against certain parasites and insects ..
- Flax, kidney beans and petunia protect the potato from Colorado beetle;
- tomato and clover protect the cabbage from the fly;
- celery and carrot protect the onion from the fly;
- hemp protected the potato from the grillotalpa;
- leek and cauliflower protect celery from septoria;
- oats, tomatoes and wheat protect the asparagus from the fly;
- spinach and lettuce protect chard from the altica;
- the marigold protects the bean from weevil.
