Product description
Worm castings are finished soil, not fertilizer

Earthworms eat organic matter and leave behind a fine, dark material that plant roots can use immediately. Nothing to dilute, no burn window, no schedule to keep. The microbes that came through the worm keep cycling nutrients and holding moisture for months, so your soil improves each season instead of getting depleted. We raise the worms and screen every batch ourselves.

Why ours is different
We raise the worms ourselves and screen every batch by handLiving, not sterilized — the biology is the productWon’t burn at any normal rate, so it’s hard to get wrongSafe around kids, pets and food crops with no waiting periodMade in the USA by a family company in Grandview, Missouri
How To Use Worm Castings:

POTTING & SEED STARTING
Mix 1 part castings to 4 parts soil. Works for houseplants, seed trays and transplants.

TOP-DRESSING
Spread a quarter-inch around the base of established plants every 4 to 6 weeks.

PLANTING OUT
Add half a cup to each hole. Roots find it as they spread, with no transplant shock.

HEAVY CLAY OR TIRED SOIL
Work it into the top few inches. Improves structure and drainage over a season.
