Primo HG 500ml Plant Growth Regulator

PRIMO® HG Turf Growth Regulator helps you achieve a greener, denser, and more resilient lawn with less mowing and less maintenance. By reducing leaf growth and clipping volume, it keeps your lawn looking professionally maintained while saving you time and effort.

Trusted by turf professionals, PRIMO® HG works by regulating leaf and stem elongation to improve surface quality, colour, and overall turf performance. It also helps pre-condition your lawn to better withstand stress.

Applied at recommended rates, PRIMO® HG can reduce clipping yield by approximately 20–50% over a 2–6 week period. Growth regulation typically begins within 3–5 days of application. Results will vary depending on environmental conditions and lawn management practices, so application rates may need to be adjusted to suit your specific growing conditions and desired level of growth control.

Enjoy professional-quality turf at home — with less work.
