Egmont Fish & Seaweed Growth Booster is a concentrated liquid fertiliser that combines fish and seaweed with Trichoderma. Trichoderma is a fungus widely studied as a plant biostimulant, and research links it with improved nutrient uptake and growth. Seaweed extracts are classed as a separate, non-microbial biostimulant. Suitable for a wide range of vegetables, herbs, annuals & perennials, trees & lawns.
