(Free shipping)

Give your garden long-lasting, natural nourishment with our 25L Seaweed Fertiliser Pellets — a premium, organic slow-release feed designed to enrich soil, strengthen plants and support healthy growth all year round. Made from seaweed-rich material that has been blended with concentrated liquid seaweed extract, sun-dried and pelleted, these nutrient-packed pellets deliver continuous nutrition as they gently break down into the soil.

Each 25L bag begins with 40 litres of raw seaweed material enhanced with 3 litres of concentrated seaweed fertiliser, creating a powerful soil-enriching supplement ideal for vegetables, fruit trees, flowers, borders, lawns and container plants. Simply scatter the pellets around the base of your plants or mix into compost to boost soil life, improve structure and enhance overall plant performance.

These seaweed pellets are rich in natural minerals, complex carbohydrates, trace elements and bioactive compounds that are essential for vigorous root development, stronger stems, healthier foliage and improved resilience against pests and environmental stress. Suitable for use all year round, they are perfect for revitalising tired soils, enriching compost mixes and supporting healthy growth cycles.

Seaweed contains no transferable plant diseases, making it one of the safest and most effective natural fertilisers available. With its naturally high iodine content — often lacking in soils — this product is especially beneficial for fruit and vegetable growers. Whether you’re improving soil structure, boosting root systems or feeding heavy-duty crops, these seaweed pellets offer a powerful, organic solution for long-term garden health.
