Welcome
The Sussex Seaweed Co.
Organic Seaweed Nutrition for Stronger, Healthier Plants
We’re here to help a new generation of gardeners grow more sustainably, bringing the natural and organic products trusted by large-scale organic farms to home gardens. Our organic liquid seaweed plant feed is formulated to deliver consistent, reliable results, providing plants with a rich source of natural bioactive compounds that enhance growth, resilience, and overall vitality.
Our product is produced using high‑quality, certified organic seaweed and a refined extraction process that preserves key nutrients, trace minerals, and growth‑stimulating compounds. This ensures a stable, effective feed that supports root development, improves stress tolerance, and promotes balanced, healthy growth across all plant types.
Our commitment extends beyond the formulation itself. We design our packaging with longevity and practicality in mind — using recyclable materials and developing refill options to help reduce waste and encourage responsible use. Sustainability is built into every stage of our process, from sourcing to bottling.
We work with trusted UK and Irish suppliers to ensure full transparency and traceability throughout our supply chain. This approach supports coastal communities, protects marine environments, and guarantees that every bottle meets the highest standards of quality and integrity.
By choosing seaweed‑based nutrition, growers can help restore soil structure, support beneficial microbial activity, and reduce reliance on synthetic inputs. Seaweed has the potential to strengthen ecosystems, contribute to regenerative growing practices, and reshape how we think about plant care.
Join us in building a healthier, more sustainable future for gardens, growers, and coastal landscapes.

🌿Key Benefits
Boosts Natural Plant Defence
Seaweed contains bioactive compounds that support natural defence pathways, helping plants tolerate environmental stress such as cold, heat, and pest pressure.
Rich in Bioactive Molecules Provides naturally occurring growth‑stimulating compounds that support balanced physiological processes throughout the plant’s lifecycle.
Promotes Strong Root Development
Encourages robust root systems, improving water uptake and helping plants maintain resilience during dry periods.
Enhances Soil Biological Activity
Feeds beneficial soil microbes, contributing to improved soil structure, nutrient cycling, and long‑term soil health.
Certified Organic & Sustainable
Made using high‑quality organic seaweed from trusted UK and Irish suppliers, ensuring traceability and environmental responsibility.
🌿When to Use
Active Growing Season
Apply every 2–4 weeks from March to September to support steady vegetative growth, flowering, and fruiting.
Propagation & Establishment
Use a weaker dilution when sowing seeds, raising seedlings, or transplanting young plants to help reduce transplant stress and encourage early root formation.
Recovery After Stress
Apply after frost, heat stress, drought, or pest damage to support natural recovery processes and help plants regain vitality.
Dormant Season
Outdoor plants typically require no feeding between October and February when growth slows and soil biological activity decreases.
Indoor and Greenhouse
Indoor plants benefit from light, regular feeding throughout the year. Apply a diluted solution every 3–4 weeks to maintain steady growth, support root development, and offset the limitations of indoor or protected environments. Greenhouse crops may require slightly more frequent feeding during active growth, as controlled conditions extend the growing season and promote faster recovery after stress.
🌿How to Use
Shake Well Before Use
Organic extracts can naturally settle. Shake thoroughly to ensure an even distribution of nutrients and bioactive compounds.
Standard Dilution
Mix 50ml of concentrate into 5 litres of water to achieve a standard 1% dilution suitable for general feeding.
Soil Application (Root Drench) Apply directly to the soil around the base of the plant to support root development and soil microbial activity.
Foliar Application
Spray onto leaves in the early morning or evening. Foliar feeding allows rapid absorption of bioactive compounds through leaf tissue.
Suitable for All Plant Types
Safe for indoor and outdoor plants, vegetables, ornamentals, shrubs, and container-grown crops.
