Have questions about worm castings? We can help!

Worm castings are the manure created by a worm. Worms consume dirt and organic matter and then
produce tiny round balls called worm castings. They are a natural soil supplement found in nature that
has a number of benefits to plants and the soil they're planted in.

Worm Castings are produced naturally simply by worms “using the bathroom.” In much of the soil found in nature,
you'll find worm castings mixed in. At Simple Grow, we produce them in 100% pure concentrations in
our temperature-controlled facility. Our proprietary process ensures that only the highest-quality
castings are produced and only castings are left in the product.

Simple Grow Soil Builder worm castings are organic. The worms are fed a controlled diet of organic
matter and there are no pesticides or GMO's used in the production of the castings.  Not all worm castings are organic, it is important to check with the manufacturer about the specific soil and diet the worms are fed to insure truly organic castings.

Our worms are African nightcrawlers. The worms live in temperatures of 70 to 90 degrees comfortably
and are perfect for making castings. They also happen to make fantastic fishing bait!

No. It really doesn't smell. I know it's hard to believe, but worm castings don't smell bad like regular manure. If smell is a concern for your manure or fertilizer needs, worm castings win, hands down.
