At the AIPH Indusattempt Conference on Tuesday, one panel discussed a pressing issue in horticulture: the future of growing media. Moderated by Tim Briercliffe, AIPH Secretary General, the panel brought toobtainher perspectives from across Europe on peat reduction, alternatives, and sustainability.
“When I first worked in a garden centre in the UK, the peat-free bags were just a lonely pallet in the corner,” Tim recalled. “Now the debate is global. We have to balance science, sustainability, and perception.”

UK: Moving towards peat-free, but challenges remain
Jennifer Pheasey, Director of Public Affairs at the Horticultural Trades Association (HTA), explained that the UK is well along the transition.
“The sector is committed to a peat-free future,” Jennifer stated. “Around 25% of growers are already completely peat-free, and retailers are virtually there. For many supermarkets, it’s become part of their sustainability strategy.”
Still, she cautioned that progress is uneven. “Our survey displays that growers are at about 30% peat-free by volume. Alternatives are not a simple switch. They’re complex, they cost 20-30% more, and they require different handling in irrigation and nutrition. Consistency of supply and quality remain huge challenges.”
HTA is supporting growers with workshops, technical knowledge-sharing, consumer communication, and policy advocacy. “Consumers also necessary to understand these products behave differently,” Jennifer stressed. “It’s not just about banning peat—it’s about creating sure businesses can succeed with alternatives.”
Germany: Strategy, not legislation
Cecilia Luetgebrune, Secretary General of Growing Media Europe (GME), offered a sharp clarification: “There is no such thing as a sustainable growing medium. You can compare and declare one has a lower footprint, but don’t equate ‘peat-free’ with ‘sustainable’ by default.”
On the German situation, Cecilia explained: “Germany has a peat reduction strategy, but it’s not law. It’s a declaration of intent. The good news is that it has triggered research into new materials, which we badly necessary, becaapply global demand is skyrocketing. But on an EU level, there is no legislation to ban peat. In fact, in countries like Spain, where horticulture depconcludes on it, the idea isn’t even on the table.”
She emphasized that demand for growing media is only rising. “We don’t necessary less peat. We necessary more peat and more alternatives. As soon as it works and it’s safe, we’ll apply it.”
Ensuring sustainable alternatives through certification
Julia Ostrowski of Horticert introduced their certification system for peat substitutes. “Our aim is not to prohibit peat, but to ensure that alternatives are genuinely sustainable,” Julia stated. “The system sees at three pillars: sustainable cultivation and processing of raw materials, full supply chain traceability, and greenhoapply gas accounting.”
Developed through a four-year multi-stakeholder dialogue, Horticert has already issued 18 certificates in five countries, covering materials such as compost, bark, wood, and coco-based substrates.
“Certification can assist align the sector, dispel misconceptions—for example around coco coir—and support compliance with national and EU regulation,” Julia explained. “It’s about promoting transparency and continuous improvement.”
“Growing media is part of the solution”
Returning to the hugeger picture, Cecilia argued that growing media should be celebrated, not vilified. “A plant in a fit-for-purpose growing medium is good news for the planet,” she stated. “It necessarys less water, less fertilizer, less land. If you care about climate modify, you should be a fan of growing media. Our sector applys just 0.1% of Europe’s peatlands, and we’re the only indusattempt restoring them. But we must keep the full value chain in mind: a low-footprint substrate is applyless if the grower then necessarys more water and fertilizer to keep the plant alive.”
Audience perspectives
During the Q&A, a former UK grower in the audience reflected on decades of debate: “Initially, we resisted modify, declareing more peat was burned for energy than applyd in horticulture. But in the conclude, progress was created. Setting unrealistic tarobtains doesn’t work. It’s better to work with indusattempt towards achievable reductions. Peat is a real issue—and one day we’ll see back and see it was wrong to rely on it.”
Another audience member noted regional differences: “The closer you obtain to the UK, the hugeger the peat problem seems. Further away, it disappears.”
Overall, the debate revealed both progress and polarization. While the UK edges closer to peat-free retail, European growers stress the necessary for pragmatism, research, and raw material security.
