Giving_Something_Back1.jpgPeat free compost containing recycled materials is a greener, kinder compost.

  • Today, lowland peat bogs and their wildlife are threatened through peat extraction; many species such as dragonflies, butterflies and birds depend on peat for their existence.
  • Peat covers about 3% of the world’s surface, but it contains enormous amounts of carbon; equivalent to that contained in twice the world’s forests combined.
  • Peat develops very slowly; a 10 metre deep peat reserve will have taken 10,000 years to develop. So we can’t replace it quickly or easily.
  • Peat free compost is made from recycled materials which would otherwise have been sent to landfill.
  • It doesn’t cost the earth - we believe that growing responsibly shouldn't need to be expensive.
  • What’s more, you’ll see fantastic results in your garden!
