OMRI Certified organic worm castings are nature’s best fertilizer!

Earthworms are some of the cleanest, most helpful creatures in the world. They form their waste in tiny, ball-shaped black pellets called castings. Worm humus is the end product of their breakdown of organic matter. This manure is also known as vermicasting.

This product carries the Organic Materials Review Institute (OMRI) label. According to the U.S. Department of Agriculture's National Organic Program regulations, you can use it in certified organic production or food processing and handling with no restrictions. These American worm castings are organically made in Tennessee.

Organic worm castings are perfect for your vegetables, fruits, trees, shrubs, flowers, potted houseplants, and more! These castings act as a repellent to whiteflies, aphids, spider mites, and other pests that feed on plant juices.

The castings are odor-free and contain no added chemicals, perfumes, or scents. Use them directly from the bag on all plants indoors and out, in the house or garden. With castings, you can grow pesticide-free food!

Nontoxic and safe for exposure to children and pets, the castings won’t burn plants in any concentration. They provide the soil with essential enzymes, trace minerals, and helpful nutrients without alteration. Adding an abundance of nutrients (including nitrogen, calcium, magnesium, potash, and phosphates), they naturally improve soil quality by acting as sustained-release plant food.

Plants use castings to fight off fungal diseases. The castings’ high concentration of beneficial bacteria and microbes work with elements of the soil to resist plant decay.

As long as this product is stored in a dry place and does not come in contact with moisture, the worm castings have an unlimited shelf life.

The castings aid soil aeration like little blocks of wood in a bucket: They create open space for oxygen, so a plant’s root system can thrive and expand. Allowing the soil to drain unnecessary water easily, the castings ensure plant roots do not become waterlogged or develop root rot. Moreover, because the castings contain absorbent organic matter that stores moisture the roots need, their presence improves the soil’s water retention capacity.

Worm castings are the best multipurpose, all-in-one soil amendment anywhere!
