1. Banana peel


Rich in potassium, banana peel helps with flowering and fruiting. It can be cut into small pieces and mixed directly into the soil, or blended with water to be used for watering.

2. Coffee grounds


With a high nitrogen content, coffee grounds are ideal for plants that require more vigor, such as foliage. Once dried, it can be mixed into the substrate or applied in composting. Avoid excessive use to not acidify the soil.

3. Eggshells


A source of calcium and minerals, crushed eggshells improve soil structure and prevent pest proliferation. When dried and crushed, they can be incorporated into the garden or pots.

4. Vegetable cooking water


Rich in nutrients released during cooking, this water should be used cold and without salt. It's a practical way to reuse what would be discarded and nourish plants in a balanced way.

5. Wood ashes


The ashes from fireplaces, barbecues, or campfires made from pure wood are rich in potassium and phosphorus. They work well to balance the soil's pH, as long as used in small amounts.

6. Home composting


Transforming organic waste into fertilizer is a comprehensive practice of natural fertilization. Peels, leaves, stems, and even untreated paper can comprise a home composter, generating humus and plant leachate for direct application.

How to use natural fertilizers in daily life


Incorporating natural fertilizers into the routine requires observation and respect for the plants' timing. Each species has specific nutrient needs and cycles and more is not always a sign of care! Generally, application can be made directly into the soil or diluted in watering, depending on the type of fertilizer and the plant in question.

The ideal is to start slowly, experimenting with combinations and observing the plant's response over the days. Firm leaves, vibrant color, and well-developed roots are positive signs. Yellowing leaves, compacted soil, or strong odors may indicate excess or imbalance.
