Peat Moss Harvesting

Extra Fine Grade Peat Moss
Extra Fine Grade Peat Moss is designed for seedling beds, plug mediums, hydro seeding and other applications where zero stick/twig contamination is essential.

Fine Grade Peat Moss
Fine Grade Peat Moss is used for hydro seeding, golf green construction, nursery beds, and other applications where an even granular size and low stick content is required.

Medium Grade Peat Moss
Medium Grade Peat Moss is designed for greenhouse nurserymen and other professional horticulturists who require a product with a low amount of sticks and nuggets, while maintaining a good fibre structure to allow for high water absorption.

Coarse Grade Peat Moss
Coarse Grade Peat Moss is ideal for plant propagation. It boasts an excellent air filled porosity (AFP), allowing roots to grow and expand to their maximum capacity. It is also preferred by mushroom growers for its fibre structure and water absorption properties

Extra Coarse Grade Peat Moss
Extra Coarse Grade Peat Moss has the highest air-filled porosity (AFP) for aeration, drainage, and strong root development. It is excellent for maturing plants.
