About Us

Peat bogs were formed from melting glaciers.

Plants grew and died, creating decomposed organic residue.

Sphagnum peat moss holds nutrients in the soil.

Canada is the source of Sun Gro’s peat moss, home to 270 million acres of bog in northern wetlands. This is 25% of the world total.

The peatland is harrowed inches deep and vacuumed up.

There are only 40-50 suitable harvest days per year.

A typical harvest delivers 75% professional grade (closer to the surface) material and 25% consumer retail grade material. 

We specialize in identifying peat bogs with exceptional horticultural potential. When a suitable site is recognized, we create a comprehensive end-of-life reclamation plan.
