You’ve spotted the HORTICERT Seal? Click here & learn what’s behind it!
The HORTICERT Seal makes it easy to see at a glance whether a growing media product contains certified, sustainable peat substitutes. Since early 2025, you can find the Seal on selected products, such as at toom Baumarkt DIY stores.
The HORTICERT Seal…
- confirms that the used peat substitutes are produced in a socially, environmentally, and economically sustainable way
- confirms that the product contains at least 25% HORTICERT certified peat alternatives
- provides a transparent disclosure of the exact percentage of certified peat alternatives in the final product (coming soon)
- provides optional information from the manufacturer on how much greenhouse gas emissions were saved by using peat substitutes compared to a 100% peat-based reference mix
Make a conscious choice: Look for the HORTICERT Seal next time you buy potting soil – and actively contribute to a more sustainable future with your purchase.

Peatland Protection is Climate Protection
Globally, peat is still the most widely used raw material for potting soils and growing media. However, peat extraction in drained peatlands is associated with high greenhouse gas emissions.
Peat is created by the accumulation non- or barely decomposed organic material in the absence of oxygen. This process occurs in intact, water-saturated peatlands. Intact peatlands bind six times more carbon in the soil than forests in the same area. Therefore, they are crucial for climate protection.
The certification system is developed and implemented by Meo Carbon Solutions GmbH on behalf of the Federal Ministry of Agriculture, Food and Regional Identity (BMLEH), represented by the Agency for Renewable Resources (FNR).
