Wicked Organic Greensand

The Mineral That Fixes the Soil Itself — Slow Potassium, Iron, and Better Structure

Old Cobblers Farm Wicked Organics Greensand is a natural mineral amendment — glauconite, a marine mineral from ancient seabeds — that works on the soil as much as on the plant. Its guaranteed 3% potash (K₂O) releases slowly, while its real value is physical: greensand has a remarkable capacity to hold and exchange nutrients and water, so it loosens heavy clay for better drainage and helps sandy soil hold moisture in the root zone. It also carries iron and trace minerals, and because the analysis is so gentle, it will not burn — at any rate, on any plant.

Think of it less as a feed and more as a long-term soil conditioner you build in once and benefit from for years. Worked into beds, planting holes, container mixes, and seedling blends, it improves soil structure and the soil's ability to hold onto the nutrients you add. It's the classic organic answer to two opposite problems — clay that won't drain and sand that won't hold water — and a slow, steady potassium source besides.

Key Benefits

Conditions clay AND sand — Greensand's high holding capacity loosens dense clay for drainage and helps sandy soil retain moisture in the root zone — the same mineral fixes both problems.

Slow-release potassium — The guaranteed 3% potash releases gradually, supporting plant health over the long term without a flush.

More than one nutrient — Supplies iron and trace minerals alongside its potassium — a mineral broadening of the soil's nutrient base.

Will not burn — So gentle it will not burn — apply at any rate, on any plant, in beds, containers, and seedling mixes alike.

 Better nutrient holding — Improves the soil's capacity to hold and exchange the nutrients you add, so other inputs work better.

 Long-term conditioner — Built in once, it keeps conditioning for years — a foundation amendment, not a season's feed.

Where to use it: vegetable and flower gardens, lawns and turf, trees and shrubs, container plants and seedling mixes, clay-soil improvement, and potash-deficient soils confirmed by a soil test.
