Real Human Hair ~ today’s donation from my hairdresser friend ~ is really useful in vegetable beds and gardens, I kid you not.
I sun dry them, snip them up to lengths that I can scatter without too much entanglement, and then just spread them all over. It becomes a barrier/repellent to those slimy slugs and snails and provides nitrogen to the plants. (Some gardeners say it repels rodents but that I can’t vouch for.)
If you are into organic gardening, try it. Hey, is this recycling or what?!
