PGR – The Lawn Hack Professionals Swear By
Sick of mowing every weekend? NZLA PGR is the secret weapon golf courses and stadiums use to keep grass under control. It doesn’t just slow growth, it forces your lawn to grow smarter, building deeper roots, denser turf, and stronger colour.
What is a plant growth regulator?
A Plant Growth Regulator for lawns is a product that changes how your grass uses energy. The active ingredient in NZLA PGR is trinexapac-ethyl, the same technology used in the professional product Primo Maxx. It doesn’t stop growth, it simply slows the upward push of the canopy and encourages your lawn to invest more in its roots and lateral spread.
The result is a lawn that stays greener, denser, and easier to maintain.
Why professionals use PGR
In the ProTurf industry, the main purpose of PGRs isn’t just cutting back mowing, it’s about building stronger roots and turf resilience. Deeper roots give golf greens and sports fields better drought resistance, faster recovery from wear, and a tighter, more uniform playing surface.
The benefit of reduced mowing is a positive side effect, but the real value is in turf that can handle heat, stress, and heavy use. Homeowners using NZLA PGR get the same advantage, just on a smaller scale.
Best time to apply NZLA PGR in New Zealand
For cool-season grasses like ryegrass, tall fescue, and fine fescue, start applications in spring (August–September) and reapply every 4–6 weeks through to autumn (March–April).
For warm-season lawns such as kikuyu or couch, begin in late spring and continue through summer, when these grasses are actively growing.
A handy tip: spray PGR before heading away on holiday and you’ll return to a lawn that hasn’t exploded with growth.
How to apply NZLA PGR
Apply NZLA PGR at 15–30 mL per 100 m², diluted in 4–5 litres of water. Spray evenly across a dry lawn, and try to apply in the morning or evening when it’s cooler. Leave at least six hours either side of mowing for best results.
The effect lasts for 4–6 weeks, so reapply regularly during the growing season to maintain consistency. Many homeowners also mix PGR with liquid fertilisers or fungicides to save time, though it’s always smart to test a small patch first.
Benefits of NZLA PGR
Cut mowing time in half
With growth slowed by up to 50%, most lawns only need mowing every two weeks instead of every weekend. It’s less time behind the mower and more time enjoying your lawn.
Develop stronger roots
This is the main reason professionals use PGR. Trinexapac-ethyl encourages deeper, stronger roots, which makes your lawn more resilient to heat, drought, and heavy use.
Keep a greener colour for longer
NZLA PGR helps lawns hold onto their rich green colour, even through summer stress. A darker, more uniform appearance gives that professional “stadium turf” look.
Build denser, thicker turf
By redirecting growth energy sideways, PGR thickens the lawn canopy. This creates a carpet-like finish and helps crowd out weeds before they can establish.
Control aggressive runners
On kikuyu and couch lawns, PGR also slows the creeping stolons that invade garden beds, driveways, and paths. It keeps edges neat and easier to maintain.
Common questions about NZLA PGR
Does PGR stop my lawn from growing?
No, growth is slowed, not stopped. Your lawn still grows, just at a more manageable pace.
Will my grass turn yellow?
Sometimes you may see slight yellowing after the first application, but it quickly fades. A light feed of fertiliser or tank mix NZLA Iron+ when spraying helps.
Is it safe for pets and kids?
Yes. As with any lawn product, allow it to dry before letting pets or children onto the lawn.
How long does it last?
Each application typically holds for 4–6 weeks, depending on weather and growth conditions.
Which grasses can I use it on?
NZLA PGR is safe for Ryegrass, Tall Fescue, Fine Fescue, Kikuyu, and Couch lawns.
Where do I buy PGR?
NZLA PGR uses the same active ingredient as Primo Maxx, trusted worldwide on professional turf. The difference? It’s available in smaller, homeowner-friendly pack sizes. You get the same pro-level results without the bulk order.
If you’re ready to reduce mowing, strengthen your lawn, and get that dense, green look, NZLA PGR is the solution.
