What Are Worm Castings?

Worm castings are the manure created by a worm. Worms consume large scale food wastes, organic matter and then produce tiny worm castings. They are a natural soil supplement found in nature that has many benefits to plants and the soil they’re planted in.

How Are Worm Castings Produced?

Worms eat organic materials and produce worm castings (worm excrement). At ANNELIDA, by diverting organic material from landfills we are able to create our Premium Earthworm Castings in both granular and extract forms. Our product is biologically diverse and 100% chemical-free earthworm casting with the highest functionality available in an organic plant food. Annelida Premium Earthworm Castings are OMRI listed and third-party tested to ensure consistency and quality.

Are Worm Castings Organic?

ANNELIDA Premium Earthworm Castings are 100% chemical-free, organic and is OMRI-listed for organic production use. 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.

What Type of Worms Does Simple Grow Use?

Our worms are red wriggler earthworms (Eisenia fetida). With our patented, automated technology and smart systems, these worms allow us to produce 5000-6000 lbs of castings per day in a relatively small space with less staff.

Do ANNELIDA Premium Earthworm Castings Smell?

No. It really doesn’t smell. Even if you have the most sensitive nose in the planet, at most you can only smell the nice, natural earthy odour coming from our chemical-free, OMRI-Listed worm castings

Can I Use Too Much Worm Castings On My Plants?

Luckily, it’s really not possible to use too much worm castings. Castings are not considered a “hot” type of soil supplement. That means they will never burn the roots of a plant like chicken manure and other products. You don’t have to use much to make a big difference, but even if you planted something in 100% worm castings, it would still grow.

Are Worm Castings Dangerous?

Not at all. The product is completely 100% chemical-free, all organic, and it’s safe to touch. It physically can’t catch on fire. Our OMRI-Listed Premium Earthworm Casting is the safest soil supplement on the market.
