From coast to garden

Cold pressed, made in the UK

Our seaweed is harvested from the Irish Sea off Northern Ireland and cold pressed, keeping the natural goodness cold-pressed seaweed is known for, before we blend it into a concentrated liquid feed designed for gardeners. Cold-pressed Ascophyllum nodosum seaweed extract is combined with potassium humate and fulvate.
