Peat-free gardening

Peatlands store over twice as much carbon as all the world’s forests combined, despite being ten times smaller. They are unique ecosystems, with a range of wildlife depending on them. Extracting peat destroys habitats, releases carbon and increases flood risk. Preserving peat bogs is vital in the fight against climate change.

Bogs not bags

Keeping peat in bogs – and not in bags – is a crucial part of the fight against climate change. With a wide range of high-quality peat-free composts now available, here’s why it’s essential to leave peat in the ground

  • Peatlands store twice as much carbon as all the vegetation on the planet put together. This makes them the most efficient carbon sink on land.
  • A hectare of healthy peat just 30cm deep stores more carbon than a hectare of rainforest, including all its plants and soils. Peat bogs are often much more than 30cm deep, further increasing the carbon stored.
  • It takes 100 years to form just 10cm of peat in a peat bog. Extractors can take up to 22 metres of depth at once (=22,000 years to form).
  • As peatland habitat is lost, so are the rare species that depend on it.

  • Unlike in trees, where carbon is cycled relatively quickly, healthy peat bogs can store carbon for thousands of years.
  • Peat bogs act like a sponge, absorbing intense rainfall and releasing it in a regulated way to reduce flooding.
  • The UK is one of the world’s top 10 countries in terms of peatland area, with nearly 5 million acres.
  • At least 80% of our peatlands have been damaged. We have to protect what remains.

Why is stored carbon so important?

When carbon is stored in peat bogs as compounds that remain stable for thousands of years, it is ‘locked up’ long-term and not contributing to climate change. When these compounds are exposed to air or burned, such as through draining and harvesting peat bogs, the carbon forms carbon dioxide; a greenhouse gas that escapes into the atmosphere and contributes to global warming.

What the RHS is doing

RHS Gardens have been ‘no new peat’ since 1 July 2025 and the RHS has been ‘no new peat’ across all operations from 1 January 2026, including RHS Shows, Gardens and Retail. We stopped selling peat-based compost in 2019, and our retail outlets now stock the UK’s biggest range of ‘no new peat’ plants. This means plants that have been grown entirely peat-free, or older plants containing peat that was already in the production cycle before the end of 2025.

The largest peat-free research project globally, the RHS Transition to Peat-Free fellowship is developing solutions to help the horticultural industry sustainably transition away from peat. This collaborative project brings together government, growers and growing media manufacturers to research sustainable alternatives to peat in large-scale commercial settings. Led by dedicated research fellows Dr Raghavendra Prasad from 2022-2025 and Dr Yusra Zireeni from 2026, the project includes events and resources for professional growers.

RHS peat policy

Peatlands are the world’s largest terrestrial carbon store and provide valuable ecosystems for wildlife. We share the concerns about the damage peat extraction does to our natural environment and will continue to push for the end of peat use in horticulture, including through our peat-free petition calling on Government to introduce legislation banning the sale of horticultural peat in the UK.
