The Ascophyllum nodosum seaweed – with its delicate blend of growth hormones and micronutrients – has been a staple of British agriculture for centuries. The Shropshire Seaweed feed is dried and cold-pressed so none of the goodness of these underwater plants gets wasted. You’ll find no chemical supplements here, which is why the product has been approved by Organic Farmers and Growers – the highest UK standard.

The result is a versatile liquid fertilizer which delivers outstanding results across the board: increasing fruit and vegetable yields; promoting stronger, healthier flowers and plants; and producing picture-perfect lawns.

Shropshire Seaweed is harvested sustainably.


Over 100 miles from the nearest coastline, Shropshire is the last place you’d expect to find a seaweed company. When we tell local people what we do, they often look at us like we’re completely mad! However, here in the heart of rural England, we do think we know a thing or two about organic living and ‘the good life,’ which is what drove us to
develop Shropshire Seaweed.

Of course, there’s no seaweed to be found growing around these parts. We have to go to Ireland for that. The waters there are some of the cleanest in the North Atlantic, which helps to produce the healthiest and best Ascophyllum nodosum around. All the seaweed we use is grown and harvested on a sustainable scale, then it’s dried and brought by sea for processing.
