Organic Seaweed is a single-ingredient liquid biofertiliser made from Ascophyllum nodosum hand-harvested on Ireland’s coast, where cold, clean Atlantic water keeps the weed slow-growing and dense in natural plant hormones, alginates and trace elements.

Most liquid seaweed sold in the UK is produced by alkaline hydrolysis, where the seaweed is broken down in potassium hydroxide. Ours is cold-pressed instead. The fresh seaweed is pressed within hours of cutting, with no heat, no alkali and no solvent, so what reaches the bottle stays closer to the living plant.

Diluted at 50:1, it is applied as a foliar spray or soil drench through the growing season. Growers use it for root establishment, recovery after transplanting or drought stress, and to feed soil biology rather than force top growth. Cut by hand on a rotation that allows the beds to regrow.
