Sustainable gardening is becoming increasingly popular among gardeners in the UK and US. As climate change continues to impact the planet, gardeners are seeking ways to reduce their carbon footprint and protect valuable ecosystems. One way to do this is by using peat-free compost, which is now widely available in both countries.

But why is peat no longer used in compost? Peatlands are important ecosystems that act as flood inhibitors and carbon sinks. However, their use in compost has severely depleted these valuable resources. In response, the UK has banned the sale of peat-based compost, and many gardeners are choosing to switch to peat-free alternatives.

Why Use Peat-Free Compost?

Peat-free compost is a sustainable option that has gained popularity in recent years due to the negative impact of peat extraction on the environment. Peatlands are important carbon sinks, sequestering 42% of all land carbon and mitigating the effects of climate change. However, overharvesting for peat products has severely damaged more than 80% of all peatlands in the UK, releasing carbon into the atmosphere and contributing to climate change.

Using peat-free compost is a simple way to reduce one’s carbon footprint and support sustainable gardening practices. Peat-free composts are made from organic materials such as green waste and sphagnum moss, which are renewable resources. They also help to preserve peat bogs and the ecosystems they support, including natural habitats for wildlife and sources of drinking water.

In addition to its environmental benefits, peat-free compost has practical advantages for gardening. It retains moisture and nutrients, and can be tailored to suit the specific needs of different plants. While peat-based compost may have a low pH suitable for acid-loving plants, peat-free alternatives can also provide long-term benefits for container plants and seedlings.

Overall, using peat-free compost is a sustainable choice that supports the environment and promotes healthy plant growth. By choosing peat-free options, gardeners can contribute to biodiversity and water management, while reducing greenhouse gas emissions and preserving carbon stores in peatlands.

How We Chose The Best Peat Alternatives

When choosing the best peat alternatives, there are a variety of factors to consider. The team looked at the materials used in the compost, their sustainability, effectiveness, and cost. After careful consideration, the team identified the following five materials as the best peat-free potting soil:


Coir, made from coconut husks, is a natural byproduct of the coconut industry. It has an open structure, is biodegradable, and is lightweight. Coir is ideal for young seedlings and root cuttings. While coir loses an eco point for its shipping, it repurposes waste products to balance it as a sustainable alternative to peat.


Wool is an ethical byproduct of the wool industry that is natural, biodegradable, and renewable. It locks in moisture and provides a slow release of nitrogen fertilizer. Wool also contains useful trace elements like potassium, sodium, iron, and phosphorus.


Composted bark, sawdust, wood, or paper waste are all good options for peat alternatives. They have a low pH and drain well, making them ideal for gardening. Wood chips also make good mulch and are oftentimes free from forestry management.


Biochar is a form of charcoal that is perfect for climate-conscious gardeners. It stimulates plant growth effectively and works as a carbon sink, making it an excellent alternative to peat.

Home Compost

Making your own compost is an excellent way to ensure that your gardening practices are sustainable. By striking a balance between wet greens and dry browns, you can keep food waste out of landfills while feeding your beautiful garden for free.

When choosing a peat-free compost brand, it is important to look for certifications such as Organic Materials Review Institute (OMRI), Forest Stewardship Council (FSC), Soil Association, International Organization for Standardization (ISO 9001), and ISO 14001. These certifications ensure that the compost is sustainable and meets environmental standards.

Final Thoughts On Peat Compost Vs. Peat-Free Compost Brands

In conclusion, there are a variety of peat alternatives available that can be just as effective as peat-based compost. Using peat-free compost is important for reducing carbon emissions and protecting the environment. The team recommends using one of the five materials listed above or making your own compost for a sustainable and eco-friendly gardening experience.
