Instead of throwing them away, make them a natural fertilizer!
It was Paul, the gardener in my town, who explained to me how to reuse onion skins.
His recipe is super simple to make a super rich fertilizer for plants.
Since using it, I have seen my green plants grow much faster.
Here is the recipe for natural onion skin fertilizer. Look :

– 1 liter of water at room temperature
How to do
To make 1 liter of fertilizer
1. Collect the skins of 5 onions.
Note : if necessary, keep the peels until you have the right amount.
2. Cut the skins with the scissors into small pieces.
3. Put everything in the bottle.
4. Pour the water over to fill the bottle completely.
5. Leave to infuse in a temperate and bright place for at least 24 hours.

I explain how to dose it now.
How to use onion skin fertilizer?
This fertilizer is very easy to use.
Pure or diluted, it is suitable for most plants: green plants, orchids, vegetable plants, flower boxes…
Just water them normally with this mixture. That is, with the same amount of water as usual.
For my part, I put it 3 times a month in winter to stimulate flowering and growth in spring.
In summer, I reduce the dose a little to go to 2 times a month.
And I stop the contribution in autumn and beginning of winter to let the plants rest.
Note: the mixture will keep for about 15 days in the fridge, no more.
What are the benefits of this homemade onion fertilizer?
Onion skins are rich in nutrients such as potassium, phosphorus and calcium.
And that, whether the onion is yellow or red.
They are therefore beneficial for plant growth and flowering.
In particular phosphorus which stimulates the root system of the plant.
That’s why I use it on my cuttings…and you see the results in a few months!
