Topsoil & RainTopsoil & Rain — home

A worm farm you can actually see.

I started this farm with 2,000 red wigglers in the backyard.The bins multiplied the way worm bins do, and at some point "my compost hobby" quietly became "a small farm with a bagging table."

Here's the thing about bagged castings: you usually have no idea what you're getting. A photo of a worm on a plastic bag, shipped from who-knows-where, tested by no one. I couldn't change the category, but I could run one farm you don't have to take on faith.

Why "Topsoil & Rain"

“Despite all our accomplishments, we owe our existence to a six-inch layer of topsoil and the fact that it rains.”
— an old saying among farmers

The rain is up to the sky. Our whole job is the six inches of topsoil — that thin, living layer everything else depends on. That's why every batch goes to an independent lab, and every result getspublished where you can read it. If we're asking you to feed your soil with our castings, you should get to see exactly what's in them.
