Now let’s get to the topic that really interests us: How to make homemade fertilizer for potted plants.

To achieve this, we must follow these points:

  1. Get a small container about a meter deep (a large or medium-sized container will also work, depending on your needs). Once we have it, make holes in the surface.
  2. Put between four and five fingers of land inside. If the container is bigger, we will have to place more.
  3. Add organic waste like the ones we mentioned above. Of course, they must not be made from any animal products except eggshells.
  4. Return to put earth on it, to cover debris.
  5. Remove with a shovel approximately every two weeks. To do well, you have to bring the remains that are lower to the surface and those from the surface to the bottom. In this way we aerate our homemade fertilizer.
