Most people throw it away, even though onion skins are worth their weight in gold.

A cheap trick from the kitchen that also works in the garden

Peeling onions is a daily routine in most kitchens. The dry peel often ends up in the trash without a second thought. However, what we see as waste could actually be used in many ways.

In recent years, more and more people have been trying to be more conscious about their kitchen scraps. Not out of fashion, but out of simple common sense. Onion peels are such a small but interesting example of how to live with less waste.

Nutrients for plants

Onion peels contain small amounts of minerals and antioxidant compounds. Some gardeners use them soaked in water and watered houseplants or garden seedlings. The solution is not a strong fertilizer, but rather a supplementary support.

The preparation is simple. A handful of peels are soaked in water, then the liquid is filtered after a day. The cooled, clear solution can be used to water. You shouldn’t expect miracles from it, but it can support the soil’s microlife and be part of a more natural care routine.

Natural dye with ancient traditions

Onion peel decoction is a long-known natural dye. Many families still use it to dye eggs at Easter because it gives a beautiful, golden brown hue. No artificial substances are added to the water during the dyeing process, yet the result is spectacular.

It can also be used to dye textiles, although this requires more patience and experimentation. The color depends on the cooking time and the material used. The method is more of a craft experience than a quick fix, but that’s what makes it so valuable.
