Yarrow Fertiliser

Question

Has anyone used yarrow as a fertiliser, and which is the best part of the plant to use–just the leaves and stalk or the whole plant, including the roots?

Answer 1

In addition to its use as an herbal tea remedy for fighting off colds and flu, or its appearance in fresh or dry flower arrangements, yarrow can indeed be used as both a fertilizer and compost activator. Adding yarrow leaves to your compost pile will speed up the decomposition process, even in small amounts (It's believed that just one finely chopped yarrow leaf can produce the same results as a wheelbarrow full of compost). As fertilizer, the essential oils from its chopped leaves can boost the quality of your garden soil.
