What is the Difference Between Sphagnum and Peat Moss?

The main difference between sphagnum moss and peat moss lies in their structure and harvesting practices. Sphagnum moss is a living plant that grows on the surface of soil or a swamp, while peat moss is a mixture of decayed organic materials found in cold water bogs. Here are some key differences between the two:

• Structure: Sphagnum moss is made up of long, fibrous strands with a neutral pH and excellent water retention properties. Peat moss, on the other hand, is a compressed, decaying plant matter that is acidic and can contain up to 70% water.
• Harvesting: Sphagnum moss is typically harvested carefully to ensure the regeneration of bogs, with a cycle that takes 5-6 years. Peat moss harvesting is not sustainable, as it requires digging up bogs, destroying the potential for regeneration of the swamp.
• Uses: Sphagnum moss is often used as a seed starter, to line baskets, for growing orchids, and as additional growing material in potting soils. Peat moss is commonly used as a soil amendment to improve the moisture retention and acidity of sandy soils.

In summary, sphagnum moss is a living plant with long, fibrous strands and neutral pH, while peat moss is a decayed, compressed organic material that is acidic. Sphagnum moss is harvested sustainably, whereas peat moss harvesting is not sustainable due to its negative impact on bog ecosystems.

Comparative Table: Sphagnum vs Peat Moss

Sphagnum and peat moss are often confused for the same growing material, but they are actually two different parts of the same plant, with distinct properties and uses. Here is a table comparing the differences between sphagnum and peat moss:

Sphagnum moss is harvested carefully to ensure the regeneration of bogs and is sustainable, while peat moss harvesting is not sustainable as it destroys the potential for regeneration of swamps.
