Great Soil Doesn't Stay Great On Its Own.

A productive garden is a hungry one. Every season your heavy feeders draw nutrition up out of the bed, and you carry it off at harvest, which is exactly what's supposed to happen. Rain and watering move a little more of it down past the roots. By the second or third season, the bed has given most of what it had.

Liquid feed is a good meal. It gets taken up fast and it does what it says. What it doesn't do is put anything back into the soil itself, so your bed comes into next spring in the same shape it finished in.

Worm castings build the bed back. Feed the soil biology and it releases nutrients at the pace your plants actually draw them, with no salt load and nothing to burn. Do that a few seasons running and the soil does more of the work every year, while you do less.

What Our Worms Eat Is Why This Works

Our worms live in leaf compost aged eight to ten years, long enough to have broken down into true humus. On top of that base they're fed a controlled diet of enzyme-rich grains, minerals and cultured proteins.

Castings carry whatever the worm ate. The diet is the product. That's why ours come out dense, dark, and still alive when they reach you.

Everything is screened and cured in small batches on our farm in Newington, then packed in a breathable pouch so the biology stays active the whole way. Nothing added, nothing diluted.

3 Ways to Feed Your Garden

Seedlings & Transplants
Add a generous handful of Pure Castings directly into the hole before dropping in your seeds or transplanting to prevent root shock and trigger explosive early growth.
Top Dressing
For established vegetable beds and flower gardens, spread a 1/2-inch layer around the base of your plants and gently water it in to provide a slow-release nutrient boost.
Revitalize Old Soil
Don't throw away last year's raised bed soil! Mix 1 part Pure Castings to 4 parts depleted dirt to instantly recharge the microbial life for the new season.
