Greetings! I've mulched onion peels in my rosemary pot. Is it fine? I'm thinking about mulching onion peels in wisteria pot in March.

And yes if I mulch onion peels in my aloe Vera pot, would it be good?

Umm anyone please help me

I would say it can't hurt. are you using just the papery skin or the flesh of the onion itself? I would look into this first but I can't see how it would be bad.

yes use them. they're good for your plants-they will provide calcium and potassium to the soil as they break down. yay! never heard of using them but why not? it's a good way to recycle food and beneficial.

It's papery skin, I break it into small pieces

The onions peels, no matter how much you break them up, won't add anything to your plants until they decompose. I don't think I would want to compost in a potted plant. But I'm not sure the papery skin will do anything except float away in the slightest breeze anyway.

If I put layer of soil on them?

I'll bet you got this idea from an Internet site proclaiming "the miraculous benefits of onion skins" or something similar...right? Good for treating athlete's foot, premature baldness and flu symptoms; excellent hair thickener, skin treatment...but wait, there's more! Good for plants!

Until composted, they are kitchen waste sitting in your flower pots. They probably won't hurt unless you pile in so many they start using up nitrogen, and aren't nearly as messy as the other Internet wonder, banana peels. Given how insubstantial onion skins are, I can't imagine that even when composted they'd amount to much of anything, useful or otherwise, but hey, no harm trying!

My mother used onion skins to dye her hand-spun wool yarn during her textiles stage. Produced a pale brown hue. Another "miraculous" use if you're interested.

Thanks ☺

The micro-environment of a pot can't sustain the microbes and other organisms that turn organic matter into "compost." The most likely result if the onion stays moist enough is that you will develop a fungus gnat farm.

Some form of fertilizer is the best and only realistic way to provide nutrients to potted plants. If you are using ground soil for the pots, you can use soil from under a compost pile, or from a part of your garden where the soil has improved over the years from adding compost to the surface. And change it as often as you want. I do a lot of this because I've never found a bagged potting soil that I really liked, and it's expensive.
