Sprinkle some goodness

Biochar is an eco-friendly charcoal that can be dug into your soil to enhance its fertility and water retention. In a 40-acre woodland site in East Sussex, community-owned environmental group Sacred Earth is making it in small, ready-touse batches. Added ingredients include comfrey tea, worm casts and seaweed. The biochar comes in a compostable box and liner and, because it is freshly made, Sacred Earth recommends using it within two weeks of receipt. It costs £9.99 for 3kg (sacredearthland.co.uk).
