Vegetable fertilization: when and how


Fertilizing the garden is not always necessary; ancient beliefs have always made us believe that fertilization is useful for our vegetables but it is not so!


Excessive fertilization can be harmful: fertilizers are fixed in the soil in the form of salts and if they are not absorbed they become harmful to the roots of plants. In this regard, let's see how and when to fertilize the vegetables from our garden.

Vegetable fertilization, useful information

  • Before fertilizing, make sure that the environmental and climatic conditions allow the vegetables to be absorbed and used. An example? You never have to fertilize during periods of drought if you are unable to irrigate the garden sufficiently: without the right amount of humidity, vegetables cannot take advantage of the nutrients
  • Even if it is very cold it is not advisable to fertilize vegetables: the cold slows down the development of plants, consequently the need for nutrients drops drastically. That said, it is obvious that you will have to wait for temperatures to rise again if you do not want to throw away energy and fertilizers.
  • Another aspect to consider are the different nutritional needs of the various cultivated vegetables: vegetables with very long cultivation times, such as tomatoes and aubergines, or those most in need of nourishment, such as corn, usually have greater benefit from periodic fertilization. While short-cycle vegetables, such as salads, or capable of fixing nitrogen in the soil on their own, such as legumes (beans, peas, broad beans ...), need it less or do not need it at all. In short, what matters is to make a good fertilization of the soil before starting the cultivation of vegetables!
