  • Green manures

Natural fertilizers from fast-growing plants (alfalfa, clover, phacelia) that are buried in the garden at the end of their life cycle. Their decomposition contributes effectively to enrich and fertilize the soil.

  • Organic fertilizers

These fertilizers of animal origin (manure, bones, horns or milled edges, dried blood...) or vegetable (stubble, algae, ash...) act in the long term and favor the mineral balance of the soil.

  • Mineral fertilizers

These chemical fertilizers are concentrated in nutrients and are quickly assimilated by plants. But if they are practical to use, they are nonetheless polluting.

In any case, choose your fertilizer according to the needs of your plants and the nature of the soil. An excess of fertilizer will weaken your garden.
