The Royal Botanic Gardens, Kew announced that by the end of 2025, all plants sold in its retail outlets will be potted in peat-free compost as part of its commitment to become climate positive by 2030, and this will include its sister site Wakehurst, in Haywards Heath,
Rachel Purdon, head of sustainability at RBG Kew, said: “Using peat-free growing material across our retail range is a powerful demonstration of Kew’s broader sustainability ambitions, and a demonstration of evidence-based, science-led decisions driving change.
“By removing peat from retail items, we’re putting sustainability at the heart of everything we do and helping to support a horticultural sector that safeguards ecosystems, supports biodiversity and contributes to a more sustainable future.”
The shift supports a wider movement across the horticultural sector to end the use of peat, which has long been a standard growing medium.
Peatlands are considered one of the world’s most valuable ecosystems, acting as carbon sinks, regulating water flows, and providing wildlife habitats.
However, UK peatlands are severely degraded, with only around 6,000 hectares in near-natural condition.
Peat extraction also releases stored carbon, worsening the climate and biodiversity crises.
Kew Gardens have used peat-free media for more than 25 years, except for a small number of rare species.
Since 2021, Kew has worked with growers and suppliers to develop peat-free production for retail plants.
Hannah Oxley, head of retail and ecommerce at RBG Kew, said: “We’re proud to be setting the pace in the retail sector by committing to the sale of plants grown in peat-free material by the end of 2025.
“Our customers expect Kew to set high standards, and this milestone shows what’s possible when retailers work closely with growers to innovate, adapt and champion more sustainable choices.
“By offering high-quality plants grown in alternative materials, we hope to give gardeners confidence in the alternatives, and prove that retail can play a central role in supporting sustainable horticulture.”
The UK government is preparing to phase out the sale of peat products, and Kew hopes its early transition will help show the commercial viability of peat alternatives.
