The Lambert Peat Moss Company, founded in 1928, is one of the true pioneers in developing the peat moss industry in North America.

With the fourth generation of Lamberts, still operating from the original location in Rivière-Ouelle, Québec, along the south shore of the St-Lawrence River, we have expanded to several bogs along the North shore and near Lac St-Jean. Starting with the original product line of screened and bagged peat moss, we now offer numerous lines of professional growing mixes and retail potting mixes as well as select types of premium peat moss.

Quality First… A priority at Lambert Peat Moss.
That’s why we’re at the root of your success since 1928.

Today, Lambert supplies both the amateur horticulturalist and professional growers alike. A nationally based distribution network and strong individual product representation is always bringing new products to the trade. Lambert is able to supply the market at competitive prices to distributors and commercial users throughout Canada, United States, and Mexico via ground transportation. In order to optimize our transportation system, Lambert is able to ship directly from the production plants, and from our distribution center in Beloeil, near Montreal, Québec. We also export product via container shipments around the world to South America, the Caribbean, Asia, Middle East, and Europe. Based on our strong quality control, technical support and industry knowledge, Lambert gives their customers confidence that our product will serve their needs: service with the ability to supply products on time.


One of the secrets to Lambert’s success is our ability to quickly adapt to the customer’s requests. This devotion to meeting the customer’s needs comes from the Lambert family and their staff and has been rewarded with 90 years of success and respect from the industry.

Hand in hand the product and the service bring you the very best peat moss, grower mixes, retail peat and potting mixes…
