Natually, one of our favourite ways to support wildlife is ensuring healthy soil is within and around the garden. A good tell for healthy soil are earthworms.
Earthworms thrive in soil which is rich with organic matter. They breakdown and recycle the organic matter which helps to naturally fertilise the earth. By doing this, Earthworms increase nutrient availbility for plants and crops, help with areation and drainage and create a more stable soil structure.
Alternatively you can start your own compost heap using your garden cuttings, fruit and vegetable waste, and an Earthworms favourite - teabags!
