America’s Original Organic Fertilizer

Rooted in History

Our company traces its roots back nearly a century, stretching back to the days of the Great Depression when Herbert Hoover was President. Since our early beginnings, we have been dedicated to the craft of transforming natural ingredients into the highest quality organic fertilizers. This proud tradition began with our founder H.G. Sanders in 1929 and continues today through his great grandchildren. His knowledge and expertise have been handed down from generation to generation and helped define the organic garden for over 95 years.

A Family Tradition

If you’re an Espoma Organic gardener, you’re in good company. Maybe your mom, aunt or grandfather was an Espoma gardener too. Espoma is a tradition that many families share, and for good reason – our products have over nine decades of proven results and have claimed their rightful places among the best-selling organic fertilizers of all time. Refined and developed for nearly a century, they are classic, timeless, and built on a heritage of passion, dedication, and innovation. 

We’re Still Growing

Today we are proud to be the original and largest manufacturer of organic fertilizers in the lawn and garden industry. We have provided nearly a century of gardening joy to our customers and we’re still growing strong. We remain committed to championing organic gardening, educating people about the power growing a garden can have to uplift others, and inspiring people to express themselves through the beauty of gardening.

Manufacturing and Headquarters since 1929

Espoma began its manufacturing in 1929, made manually, in a small wooden building with a blend of nearby natural materials in Millville, NJ. When that plant burned down in 1946, it was replaced when the community rallied to save the company and a new building was erected  for manufacturing.

Since then six new warehouses have been manufactured for finished goods storage, two for raw goods storage and a state-of-the-art manufacturing plant that is capable of fill 8 bags per minute to meet demand.
