The addition of peat moss to my yard, together with liberal parts of compost, has executed wonders to manage the soil pH and rework the clay to loam. Peat moss can even be the proper pure, long-term soil acidifier for acid-loving crops like blueberries, rhododendrons, strawberries, hydrangeas, and dogwoods. Nonetheless utilizing peat moss is controversial, on account of it’s thought-about a non-renewable useful helpful useful resource: it’s harvested from massive carbon sinks typically referred to as peat bogs, which assist us all through the struggle within the route of native local weather change.
What’s peat moss?
Sphagnum peat moss, aka sphagnum peat, is a soil conditioner utilized by gardeners and farmers to decrease soil pH (make it extra acidic). It furthermore will improve the power of sandy soils to carry water and improves the drainage and fuel alternate performance of clay soils by along with pathways for air and water. Not like completely completely different pure gives like mulch and compost, peat moss doesn’t decay shortly and lasts in soil for a few years.
The place does peat moss come from?
Peat moss is harvested from a kind of wetland typically referred to as a toilet. Inside the bathroom, plant gives submerged underwater, principally sphagnum moss, decay over a complete lot of years, improve layer after layer.

Every bathroom is a pure carbon sink of immense proportions (it absorbs carbon dioxide from the ambiance). When peat is harvested from the remaining room, this carbon is launched as soon as extra into the ambiance, contributing to native local weather change.
In 2016, the U.N. launched the World Peatlands Initiative to guard peatlands, “which comprise nearly 100 instances extra carbon than tropical forests.” Aside from trying to limit peat harvest, the initiative furthermore protects peatlands from spontaneous fires attributable to deforestation, which might take many lives.
In response to The Washington Put up, “the extraction of peat requires the eradicating a WC’s residing floor to realize the partially decomposed layers beneath. It grows at a mere sixteenth of an inch a 12 months, and its mining removes layers that take centuries to develop.” In Good Britain, utilizing peat is now restricted and the federal authorities is phasing out peat moss for passion gardeners and agricultural use. The Royal Horticultural Society, an necessary gardening group on this planet, has decreased peat use by 97 p.c at its 4 main gardens in England and urges its members to do the same. Britain has misplaced 95% of this pure useful helpful useful resource, as quite a lot of the peat was harvested for burning as gasoline over loads of of years.
The Canadian Sphagnum Peat Moss Affiliation pushes as soon as extra on claims of harvesting peat bogs and its environmental outcomes. Canada, which leads the world in producing peat moss, incorporates higher than 280 Million acres of peatlands. Of that huge quantity, solely 73,000 acres have to date been harvested, a fraction of the amount naturally generated in undisturbed bogs. The group’s members take the restoration of every harvested bathroom critically. After harvesting, every bathroom is reflooded and reseeded with shredded moss grafts, which cowl the harvested net web page inside 5 years. The peat bathroom is in reality restored in 10-15 years.
