PRIMO® HG Turf Growth Regulator helps you achieve professional turf quality at home. It promotes a greener, denser, and more resilient lawn while reducing vertical growth and mowing frequency. With fewer clippings and less maintenance, you’ll enjoy a healthier, more manageable lawn that looks great all season long.

Trusted by turf professionals, PRIMO® HG pre-conditions your lawn for stress, enhances colour and surface quality, and maintains consistent growth.

How PRIMO® HG Works

PRIMO® HG is a specialised lawn growth regulator that slows down leaf and stem elongation, resulting in reduced mowing and stronger, thicker turf. Application rates are designed to provide a 20–50% reduction in clippings over a 2–6 week period. Growth regulation begins within 3–5 days after application.

Environmental factors and lawn management practices can affect results, so application rates may need adjusting to suit your local conditions and desired level of growth control.
