Did you know that there are multiple ways to use onion skin instead of just tossing it away?

That’s right, onion skin has numerous benefits – it can be used in the garden to repel pests and enrich the soil with essential nutrients, and also to improve our immune system and overall well-being. 

In this article, we are going to cover onion skin uses. From coloring stuff to crafty projects and health perks, there’s more to onion skins than meets the eye! 

For Garden Uses 

Don’t let your kitchen waste go to waste, but consider using it to improve your garden. Just like you would use eggshells to boost plant growth and improve nutrient availability, onion skins are used in a similar manner. 

1. Natural Mulch

Besides dry leaves, wood chips, grass clippings, and other popular materials used for mulch, you can also try and use dry onion skins. They make an excellent mulch that helps suppress weeds, reduce evaporation, and also regulate the temperature of the soil. 

You can simply spread onion skins around the garden bed – these will make an effective mulch.

3. To Repel Pests

Instead of using pesticides that could harm your plants, consider using onion skins to repel pests. Simply place a layer of skins around the base of your plants and the smell will help deter aphids, slugs, and other pests. 

4. Get Creative 

You can also get in touch with your creative side and make beautiful garden art with onion skins. Using onion skin is a sustainable way to make natural dyes for pots or coloring in the garden. 

5. Soil Enrichment 

Onion skins decompose slowly, which is why they should be used as a soil enrichment. When buried in the soil, they will improve soil structure, provide a favorable environment for microorganisms, and help with moisture retention. 

For Health & Other Benefits

In addition to these helpful garden uses, onion skins can also be used as a source of antioxidants that improve our health and boost our immunity. 

Besides onions making our food more delicious, did you know that the skins can be used for culinary purposes, too?
