Preparation of fertilizer with onion peels

The essential ingredient is obviously the peels of onions. While cooking, put aside the skins instead of throwing them away. It is always best to use organic onions to avoid taking unwanted pesticides. Once you have accumulated a certain amount of skins, it will be time to macerate them.

Take the harvested onion peels and place them in a blender or food mixer. Add a little water and blend until you get a pasty consistency. Water will help extract nutrients from the skins. Now you will need to further dilute the mixture obtained. The recommended proportion is 1 part onion peel solution and 5 parts water. You can choose to adjust the dilution according to the specific needs of your plants.

Once the solution is diluted, it’s time to use it on plants. You can choose to pour it directly at the base of the plants or use a sprayer to distribute it over the leaves. Be careful not to apply too much to avoid the risk of burns.

When to apply fertilizer

Fertilizer based on onion peels can be applied every 2-3 weeks during the growing season of plants. However, the advice is to carefully observe your plants and adapt the frequency of application according to their specific needs.

The solution can also be made by preparing a decoction of onion peels by boiling them in water for about 20 minutes. After cooling, the decoction can be used as a fertilizer for plants.

Be sure to use only onion peels and not whole bulbs, as the bulbs can damage the roots of plants. It is also advisable not to use onion peel fertilizer on sensitive plants such as orchids or acidophilic plants.

Lush plants

Onion peels represent a treasure often wasted in the kitchen, but they can become a natural and beneficial fertilizer for plants. Rich in essential nutrients and beneficial compounds, they can help for healthy growth, improve soil health and protect plants from diseases and insects.

Try using this homemade fertilizer and you will see the benefits of lush and prosperous plants. Not only will you save money on commercial fertilizers, but you will also help create a healthier and more sustainable environment for both plants and the environment.
