Long before man existed the land was in fact regularly ploughed and still continues to be ploughed by earthworms. It may be doubted whether there are many other animals which have played so important a part in the history of the world as have these lowly organized creatures.

Where We Are From

When he retired, airline captain Jack Chambers bought a worm farm in Northern California dreaming of spending his newfound time as a gentleman farmer. In his own backyard, Jack quickly realized organic worm matter was giving his plants a superior growing edge—no chemical fertilizers, pesticides or fungicides needed.

His soil was rich, dark and crumbly. Fruits and vegetables were the biggest, brightest, and tastiest he’d ever grown.  Potatoes grew year after year with little effort and no disease. Big, bright, beautiful flowers with strong, sturdy stalks flourished.

Knowing the worms were responsible for this bounty, Jack dedicated the next twenty-five years to researching, developing, and testing a proprietary production process designed to bring the same superior soil health, fertility, and growing outcomes to farmers, growers, and home gardeners. Today, this process serves as the foundation for all of our organic worm-based soil amendments and conditioners, producing the consistently finest quality inputs available.
