Keep it Poopy!

Super Poop: The good stuff comes out the other end.

Pure earthworm castings for pots, beds, lawns and fields. The bag is out of stock right now. Join the list and we'll tell you when it's back.

How it's made

From worm
to garden.

Six steps, one ingredient. Scroll and the trail fills in.

1

Worms eat.

Worms work through their feed, and what they leave behind is the whole product. No blending, nothing added.

Bronson, KSOne ingredient
2

Castings happen.

What the worms leave behind is castings. It is the only thing that goes in our bags.

100% castingsNothing blended in
3

We bag it.

Filled by volume, 4 quarts to the bag, about 4.7 to 5.2 pounds. Eight bags to a case, thirty-six cases to a pallet, so it ships the same to a porch or a loading dock.

Pick your size.

The 4-quart bag is the one you find in stores. Order it by the bag or the case of 8, or castings by the tote and super sack for farms and landscapers.

You use it.

Top-dress pots and beds, blend it into potting mix, or steep it for tea. The guides walk through each one.

Things grow.

Gardeners have used worm castings for generations. We will put real numbers here the day a new lab analysis is back, and not a day before.
