Dr. Russell Sharp of Eutrema Ltd introduces biostimulants = substances that improve plant growth, root development, stress resistance and photosynthesis without acting as fertilizers or pesticides. He explains how they give turf an extra performance edge when nutrition and growing media are already optimal.

Common types include seaweed extracts, amino acids, beneficial microbes, humic/fulvic acids, yucca and chitosan. Practical tips: low-dose “on/off” effects, avoid storing diluted mixes that can ferment, consider compost teas, and watch for changing regulations that may affect product availability.
