Peat 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!
