Premium Organic Compost Accelerator (Various Sizes)




Introducing the UK's Premium Compost Accelerator

from The Shropshire Seaweed Company


High Quality, Cold Pressed Kelp from British Waters


Carefully refined over a period of ten years, this is a premium organic accelerator for composters. Because when it comes to your compost, we know you don’t want to compromise.


We employ only the finest seaweed from the cleanest Atlantic waters and distil it without heat or chemicals. Then, we wait. Because some things shouldn’t be rushed.


Organic composting does not have to be complicated: if you use quality products, the results will naturally follow. 

  • Pure Ascophyllum nodosum from the north Atlantic coast
  • Accelerates the natural compost cycle to six weeks
  • Stimulates soil bacteria to help achieve higher temperatures sooner
  • Helps retain moisture within the compost pile
  • One litre of Shropshire Seaweed suitable for an average compost bucket (1 cubic metre)
  • Approved by Organic Farmers and Growers: the highest organic standard in the UK
  • Produced in the UK from sustainably harvested seaweed stocks
  • One litre of Shropshire Seaweed is enough to treat one cubic metre of compound, which is a typical household compost bin.
  • Apply the product as evenly as possible in one single application.
  • Keep the pile well hydrated for six weeks.
  • You’ll have a useable, organicall-approved compost ready to use in your borders and containers.
