Add life back to your soil with Urban Worm Castings, freshly harvested within the past 2 weeks! These castings aren't like the traditional ones you'd buy at a garden center, which are screened to 1/8". Ours are screened at 1/4", so your castings will likely have:

  • More organic matter
  • Worm cocoons
  • The occasional worm or two

We feel this offers more value to you than smaller particle worm castings which are often lower in biological activity.

Worm castings are shown to:

  • Boost plant growth
  • Speed up germination
  • Increase yield by 20-80%
  • Suppress pests and pathogens
  • Improve water retention


How long can I keep worm castings?

They can be kept for months if kept in a cool environment with decent moisture and out of UV light. Adding leaves or other organic matter for long term storage helps too. You're trying to protect the microbiology inside, so if you think of what people need - shelter, food, water - it's pretty much the same.
