Characteristics of horticultural peat

Why is horticultural peat so important for horticulturalists? Because its unique characteristics give unique results!

Technical fact sheet

The following qualities are what makes peat moss a unique and sought-after product in horticulture and agriculture, whether as a principal component in growing media or as a soil amendment:

  • It improves soil structure, increases water retention in light sandy soils and helps to reduce the leaching of nutrients. Peat moss can retain up to 20 times its weight in water.
  • It aerates and improves drainage of heavy clay soils, allowing roots to breathe, grow and better absorb nutrients.
  • It improves soil buffering capacity because peat moss is highly tolerant to pH variations.
  • It improves the cation exchange capacity (CEC) that helps to retain minerals, releasing them over time and preventing the leaching of fertilizers.
  • It is a natural resource free of weeds and pollutants.

Peat moss allows plants to grow in an aerated and well-structured soil, guaranteeing healthy and vigorous plants. It is also an approved component in the production of organically certified produce.

Environmental aspect: breaking the myth


Peat moss harvesting in Canada is strictly and closely regulated. Producers work in partnership with internationally recognized research bodies to establish responsible management practices.

The careful use of Canadian peatlands, and the investment in peatland management are clear indicators of the industry’s social and environmental commitment.
