Peatlands in Europe contain five times more carbon than forests and disturbing peat for agriculture or harvesting it for compost releases CO₂ to the atmosphere, accelerating climate change. Extracted from bogs, fens and marshes, peat is the partially decomposed remains of ancient plants and animals. This makes peat the perfect environment for seeds to germinate and establish strong roots.īut few realise that the peat compost people buy each spring for their gardens took thousands of years to form. The reason why this spongy turf is coveted by gardeners is that it can hold onto both water and air and it’s generally free of pests and diseases. Peat has been a staple ingredient of composts sold in British garden centres since the 1960s, even though it’s not actually that nutritious for plants.
