More Details

Sustainably produced by blending bracken with farmyard manure that's then composted and allowed to cure over time, this humus rich soil conditioner will benefit heavy, clay soils by aiding drainage and improving structure.

The lignin contained in the bracken breaks up the clay and releases the nutrients held within.

  • 40L.

The order was delivered very promptly. The soil improver was well packed and easy to spread on to my solid clay flower bed. Now I need some rain to get it working! Will be ordering more. A very happy customer.
