How do worm castings work?

As organic matter moves through the digestive system of the red tiger worm (eisenia fetida), a thin layer of oil is deposited on the castings. This layer erodes over a period of 2 months, making plant nutrients more readily available through roots, which is slowly released to sustain growth over longer seasonal periods.

Why should I use worm castings?

Worm castings offer rehabilitation for depleted soil; they’re loaded with healthy microbial life: completely eco-friendly, safe and effective; are a non-toxic pest and ant repellant, turns harmful fungus into a food source; reduces water bills; creates soil composites and root development; and drastically improves the overall health, growth rate, and yield for your lawn, foliage, garden, and crops.

What about nutrient content?

Worm castings are the richest natural soil builder and nutrient provider known to man. As little as a tablespoon of pure worm castings provides enough organic plant nutrients to feed a 6″ potted plant for more than two months.

Will worm castings help my plants grow stronger?

Worm castings build a denser mico-rhizomosphere that enriches plants root system, holds more water, and promotes the development of a healthier immune system in resistance to drought, pests, root rot, and harmful fungi. Premium Red Worm Castings are concentrated nutrient dense soil supplements; a little goes a long way.

What is humus?

Worm castings contain humus, a natural soil, root, and aeration builder for healthy micorhize and the support of soil insects that perform delivery and uptake of micro-soil nutrients into the plants root system.

The Scoop on the Poop

Compost-WormsWe’re the real deal.

With Premium Red Worm Castings you get 100% worm castings, not just lip service. We feed our worms 100 lbs. of manure and we get 20 lbs. of pure castings. The worms are allowed to eat all the food and to process it through their 104 different enzymes digestive system, until there is no manure left. We offer only the pure, nutrient dense, black, organic soil supplement directly from red worms.

Nothing else compares!
