A super effective fertilizer for plants and flowers: find out how to make it from waste!

But also:

Vegetables, algae, ashes

We usually throw away vegetable water, but in reality, even the latter can become an excellent method to promote the growth of your plants. In fact, it is rich in nutrients for plants. Seaweed, for example, is used in some recipes to add flavor to dishes, and is then thrown away. But if you chop it up and add it to the water used to water your plants, they will then become more flowery.

Ash, even from your fireplace, so wood, is just as effective. Just scatter it on the surface of the soil so that it brings useful minerals to the soil so that the plants can feed themselves properly.
