Sustainable products for our shared future

Are you ready for the seaweed revolution?

Harvesting the ocean's power

Our oceans contain a rich bounty which has for so long been hidden in plain sight. Nutritious, dynamic and sustainable, our marine plants hold the answers to many of of the 21st century's problems.

Excitingly, we are only just beginning to realise the potential of seaweeds and Sea-Chem is in the first wave of companies developing these plants into sustainable products for home, garden, industry and environment.

Introducing the UK's Premium Organic Fertilizer

Organic all-rounder

Carefully refined over a period of ten years, this is a premium organic fertilizer for discerning growers. Because when it comes to your plants, 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 gardening does not have to be complicated: if you use quality products, the results will naturally follow.
