The need for plant nutrition in the city
In nature, plants constantly receive nutrition from the soil. This is due to the plant's life cycle: the leaves fall to the ground and are converted into nutrients for the plant. In urban areas, where there is limited buffer and medium capacity due to hard surfaces, this does not happen or happens very little. At some point, the plant has absorbed all the nutrition from the medium present. That is why it is necessary to give the plant nutrition.
