Earthworm castings are a 100% natural soil amendment from materials that earthworms have predigested. This provides nitrogen and millions of soil microbes.

A 100% organic soil amendment made by earthworms

Minerals help plants grow, but they have to be available in a way plants can absorb them. Earthworm castings are the digested excretions of worms and contain vitamins, nutrients and microbes that enrich soil and keep plants growing strong.

Earthworm castings are a valuable garden supplement that:

  • Are 100% natural containing no chemical additives
  • Safe, clean and odorless so it can be used anywhere
  • Vitamin rich containing magnesium, phosphates, calcium, potassium and potash
  • Non burning and gentle enough for use with delicate flowers and seedlings
  • Full of beneficial bacteria promoting increased soil health
  • An organic dirt “adhesive” that keeps soil particles together providing better water retention and a stronger, firmer root bed
  • A great way to transfer nutrients directly to your plants fast

Earthworm castings are a great addition to any soil and can revitalize depleted or worn out gardening beds by putting back essential nutrients plants need.

How Earthworm Castings help soil regenerate

Putting earthworm castings into your garden soil adds more than just minerals and nutrients. Microbacteria are abundant in the worm castings and when applied into the soil they begin to feed on any organic materials they find. These helpful bacteria breakdown organic materials, such as leaves and clippings, into nutritious and readily available minerals and nutrients that the plants use. Earthworm castings are an excellent way to give your soil a boost before, during, or after the growing season.

The benefits of Earthworms

When you think of earthworms, most people connect with them as either bait or the "prize" for early risers. Some may even remember science lessons about earthworms having five hearts or the ability to be cut into pieces and create new individuals. What you may not know is that earthworms actually play a very vital role in maintaining the ecosystem under the soil.

These castings are small, granule shaped pieces that resemble dirt, and can be found in piles across the surface of the ground. And though these piles are considered by some to be eyesores, smart gardeners know that a good sign of healthy soil can be judged by worm activity displayed with numerous casting piles.

Worms are busy tunnelers, aerating the soil and increasing soil drainage. Earthworm castings also cement soil particles together into water stable aggregates, which retain moisture for longer periods of time within the soil. The result is that plants not only have more water available to them, they also have it for longer durations of time.

Worms also filtrate topsoil materials downward, making surface applications of fertilizers or other soil conditioners much more effective. Their tunnels can be used by plant roots, allowing for deeper growth and easier root expansion. Even when worms die, their bodies provide easily absorbed nitrogen back into the soil that plants can use to grow bigger and stronger. Worms and earthworm castings are vital to good soil health.

Studies have shown that pasture crops and animals feeding off of them have higher yields, as much as 25% greater in areas with increased worm counts and activity. Farmers are beginning to understand that worms can actually help their bottom line substantially…no small feat for something that was only considered useful for catching fish.
