I will look for alternatives to peat moss in potting mixes and garden soil supplements. Fact: Peat bogs are crucial carbon sinks. They sequester more carbon than any other ecosystem type—forests included. Covering just 3% of our planet, peat bogs store one-third of soil carbon on Earth. Source: Treehugger
Wetlands like peat bogs are the most biodiverse ecosystems on our planet. When they are destroyed or degraded, many species of plants and animals are affected. In North America today, peat is predominantly used for gardens. Only 10% of Canada’s peat lands are formally protected.

Look for soil additives, compost and potting soils that are labelled “peat free.” Coconut coir is a good substitute, but does have a considerable transportation carbon footprint. Have you noticed any coconuts growing locally? Products labelled “Organic” and “Environmentally Friendly” may still contain peat. In the UK, the sale of peat-based compost will be banned starting in 2024.
Make Your Own:
You can make a good potting soil/ growing medium using homemade compost, leaf mold, and inorganic soil elements (loam/sand). More suggestions below.
