Ingredients
Modern farming and intensive gardening strip minerals from the soil over time. Plants need more than just N, P, and K — they require dozens of trace elements that determine the quality, flavor, and nutritional density of everything you grow.
Glacial rock dust is finely ground stone — usually granite or basalt — that was pulverized by glacial activity thousands of years ago. This grinding creates an enormous surface area that releases minerals slowly into the soil as microbes break it down.
A quality glacial rock dust contains:
When you remineralize depleted soil, you’re essentially rebuilding the mineral bank that plants draw from. Many gardeners report noticeably improved flavor in vegetables, deeper colors in flowers, and better disease resistance after amending with rock dust.
Glacial rock dust is a key ingredient in both Daley’s Mix and Premium Soil Mix — our two premium growing media. It works synergistically with the mycorrhizal fungi and soil bacteria in our blends, which solubilize the minerals over time, making them available to plant roots in exactly the form they need.
