Organic Seaweed Biostimulant 1L – Concentrated Liquid Plant Feed

A concentrated litre of pure Cornish seaweed, made to go a long way.

This 1L biostimulant is the same hand-collected, cold-pressed seaweed extract trusted by regenerative farms across the South West, sized for gardeners and serious plant keepers. It works with soil biology rather than overriding it, supporting root elongation, microbial activity and plant resilience during establishment and stress. This is not a synthetic fertiliser: it enhances the soil’s ability to supply the nutrients already present.

Diluted at 30ml per litre of water for routine feeding, or 35 to 40ml per litre for plants under stress or in high demand. Suitable for soil or foliar application, and compatible with most existing feeding routines. One litre makes up to 600 litres of diluted feed.

Made from seaweed hand-collected after natural tidal casts on Cornish beaches, then mechanically pressed and filtered with no solvents, no chemical extraction and no synthetic additives. The residual solids are retained for soil products, making the whole process fully circular and zero waste.

How To Use

Dilute 1–2ml (about 2 dropper squirts) per 1 litre of water. Use during your normal watering cycle every 2–4 weeks.
