Gardeners are being encouraged to try an unusual but popular trick this spring: adding human hair to their soil. While it may sound strange at first, experts say this simple, natural material could offer benefits for plants and help tackle some common gardening frustrations. Human hair is rich in nitrogen, a nutrient that supports healthy plant growth. As it slowly breaks down, it releases nutrients into the soil, acting as a gentle, organic fertiliser. This makes it particularly useful for gardeners looking to avoid chemical products while still giving their plants a boost during the growing season.
But that’s not the only advantage. Hair can also help improve soil structure by increasing aeration and moisture retention. When mixed into the soil or compost, it can help create a better environment for roots to thrive, especially in beds that are prone to drying out.
Another reason gardeners are turning to this unusual method is its potential to deter pests. The scent of human hair is thought to discourage animals such as deer, foxes and even some smaller critters from digging up plants or nibbling on new growth. Sprinkling hair around vulnerable areas of the garden can act as a natural barrier without harming wildlife.
Using hair in the garden is fairly simple. It can be scattered lightly over soil, mixed into compost heaps, or placed around the base of plants. However, experts advise avoiding thick clumps, as these can mat together and prevent water from penetrating the soil effectively.
However, human hair is not an instant fix for struggling gardens. While it can certainly contribute to long-term soil health, gardeners should not expect quick results or a sudden revival of weak plants. Hair breaks down very slowly in its raw form, meaning nutrients are released over time rather than immediately. Unless it is finely chopped, processed, or added to a compost heap, it can take months to decompose properly.
For this reason, it works best when mixed into compost rather than simply scattered in clumps across flowerbeds, where it may sit unused on the surface.
While it may not replace traditional fertilisers entirely, adding human hair is a low-cost, sustainable option that could complement your usual gardening routine.
