Primo HG Turf Growth Regulator helps homeowners achieve greener, denser, and more resilient lawns, while reducing mowing frequency and maintenance time. 

Formulated to reduce vertical leaf growth and encourage stronger root development, Primo HG optimises turf density, colour, and stress tolerance. By limiting excessive top growth, more energy is directed to the roots, improving nutrient uptake, water efficiency, and overall plant health.

Product Highlights

• First turf growth regulator approved for home use in Australia: Professional results, now available for home lawns.
• Greener, denser, and healthier turf: Promotes finer leaf texture and enhanced turf quality and colour with finer, denser growth
• Reduces mowing and clippings: Slows leaf growth for up to 4 weeks, meaning less mowing and cleaner lawn surfaces. It also means reduced clipping removal and less potential for scalping
• Pre-conditions turf for stress: Helps lawns withstand heat, drought, and wear during summer. Better heat stress tolerance, less wear and tear, and reduced watering needs
• Enhances root growth: Redirects plant energy below ground, promoting stronger, deeper, more efficient root systems. This improves the ability of your turf to utilise available water and nutrients
• Convenient and easy to use: twin-chamber pack for precise application.

Application

Recommended applications rates are designed to give approximately a 20 to 50% reduction in clipping yield over a 2 to 6 week period. Growth regulation begins 3 to 5 days after application. The amount of growth regulation achieved will vary between situations due to environmental conditions and lawn management practices. Therefore, application rates will need to be adjusted to match growing conditions, management practices and the amount of growth regulation required in each individual situation.
