Since the 1950s peat has been used by gardeners as one of the finest soil amendments for ericaceous plants (including heathers, azaleas and rhododendrons), as a mulch, and as a growing medium.
But peat is collected from wetlands, which harbour many rare and endangered species, and can take centuries to regenerate.
“In the past half century, 94 per cent of Britain’s lowland peat bogs have been lost,” says garden writer and BBC personality Monty Don. Which is what lead him to search out an alternative to peat.
He found it growing wild on his farm. Pteridium aquilinum, or, bracken fern, he says, is an excellent addition to compost for acid-loving plants. Trimming off the top of the plant for mulch and compost can also help bring the competitive weed under control without using chemical herbicides.
When I was a kid, I used to carefully “harvest” bracken, strip the leaves except for a frond or two at the end, and then use the poor fern as a “spear.” Thankfully, I didn’t completely decimate them, so my mom still has bracken growing everywhere. But what if you don’t have access to endless bracken fern? Must you use peat?

Chose your peat-alternative based on its planned use.
Next time you reach for peat, reach for bracken or coir instead; and save the peat bogs!
