Bioboost Natural Fertiliser 20kg

Bioboost® is an organic slow-release fertiliser suitable for lawns, trees, shrubs, flowers and vegetable gardens. It provides a steady supply of nitrogen and essential nutrients over 12–16 weeks, with up to 70% organic matter to support microbial activity, healthy growth, and strong roots. Heat-treated above 80˚C, it’s weed and pathogen free and safe for plants — it won’t burn. Bioboost’s dry pellets are easy to apply and ideal for use with a spreader. Environmentally friendly, it recycles nutrients back into the soil, reduces nitrogen leaching, and includes organically complex iron for deep, vibrant lawn colour without staining. Application Rate: For established lawns apply three times per year in Spring, Summer and Autumn at 5kg per 100m². For new lawns, mix Bioboost into the top 50mm of soil at 13kg per 100m² before seeding or laying instant lawn. After the third mow, apply 7kg per 100m².
