As you make plans to prepare your garden for the growing season, you might be wondering if a peat-free compost is the right choice for you. That's why we've searched the internet to collect information about peat-free compost, its effect on the environment, and a list of the best peat-free compost options, and compiled it all right here in this article.
Peat-free compost is preferable as peat is not environmentally friendly, nor does it work any better than more sustainable options.
Peat-free compost can be a little more challenging to find, so to help you out, we've assembled a list of the best peat-free composts available. We'll also answer some of the more specific questions you might have. So, let's get started!
Should You Use Peat-Free Compost?
From an environmental standpoint, peat-free compost is the way to go. Peat moss, also known simply as peat, is ancient, compacted, and decomposed sphagnum moss harvested from bogs that exist primarily in Europe and the U.K. Since peat takes hundreds of years to form and we're using it faster than it is created, it's not considered a renewable resource. Peat bogs also create a delicate ecosystem that is ruined as the peat is harvested. And finally, peat contains climate change-causing carbon, which is released into the atmosphere when the bogs are drained during harvest.
Additionally, peat doesn't make unusually good compost or growing material. Even though it contains many nutrients, it also dries out quickly and blows away instead of decomposing into the soil. Peat is very helpful for aerating the soil, but there are more sustainable alternatives such as coconut coir or worm castings that work just as well. Coconut coir, in particular, has a comparable texture and aerating capabilities. To learn more about when to add compost to your garden, check out our article When to Add Compost to Your Garden?
Is Organic Compost Peat-Free?
Since organic compost tends to be made by companies that are reasonably aware of environmental issues, they typically sell compost that does not contain peat. However, this is not a guarantee. Unless a bag of compost explicitly states that it is peat-free, it's safe to assume that it contains peat.
Is Peat a Good Compost?
Even though peat has been used as compost for years, it's not very good for the environment, as we discussed earlier in this article. It also doesn't make the best compost since it dries out easily and can then blow away in the wind rather than decomposing in the soil. Coconut coir, worm castings, manure, and decomposed plant matter from your kitchen or garden make great substitutes.

Is Peat Moss Good For Clay Soil?
Peat moss is useful for aerating clay soil and making it more suitable for growing plants. However, it is also quite acidic and should be accompanied by lime to offset that tendency. However, it's not the only way you can improve clay soil. Peat-free compost and aged manure work just as well and don't increase the soil's acidity. You can also grow a cover crop such as crimson clover, buckwheat, or soybeans and then work it into the soil when the plants are a few inches tall to reduce the presence of clay.
