A professionally installed artificial putting green is designed to provide years of enjoyable, low-maintenance performance.
Unlike natural grass, there’s no mowing, fertilising or irrigation to worry about. However, like any outdoor surface, a little routine care will help keep your putting green looking its best and performing consistently for years to come.
This guide explains the simple maintenance steps that will help protect your investment and maintain a smooth, consistent putting surface.
Why Maintenance Matters
An artificial putting green requires a fraction of the upkeep of natural grass—no mowing, watering, fertilising, or rolling required. Because Unreal Lawns builds every green using TrueRoll Hybrid PE/PP dual-yarn turf over a free-draining compacted aggregate metal base, routine maintenance is fast and straightforward. A brief tidy to clear organic debris and an occasional brush are all it takes to maintain tour-speed stimp readings year-round.
Simple Care for Tour-Level Performance
-
1. Debris & Leaf Removal: Use a leaf blower, soft broom, or plastic rake to clear leaves and organic matter. Clearing debris prevents organic decay from settling into the turf matrix and stops moss from seeding in shaded corners.
-
2. Occasional Cross-Brushing: Brushing against the pile using a soft-bristled broom lifts fibers and evenly distributes the kiln-dried silica sand infill. Because TrueRoll Hybrid utilizes upright Polypropylene fibers interwoven with soft Polyethylene, light brushing restores upright fiber tension and maintains a true, grain-free ball roll.
-
3. Free-Draining Heavy Rain Care: Our sub-surface aggregate metal base shifts heavy Kiwi rainfall instantly. After severe storms, inspect the surface and brush away any stray organic silt to keep the drainage pores open and free-flowing.
-
4. Silica Sand Top-Ups: The rounded silica sand infill stabilizes the turf backing and regulates ball speed. Depending on usage, sand levels should be inspected every 2 to 3 years and lightly topped up if required to preserve consistent stimp speed.
Weed & Moss Management in New Zealand Conditions
Weeds cannot grow through our compacted aggregate base and heavy geotextile membrane. Any stray weed seeds carried by the wind into the fringe turf can be quickly plucked out by hand or treated with a mild, water-based weedkiller. If your green is situated in a heavily shaded or damp area, applying an eco-friendly, turf-safe moss treatment once a year during winter will keep the surface clean without damaging the dual-yarn PE/PP fibers.
Looking After the Surrounding Landscape
Your putting green is only one part of your outdoor space. Keeping nearby garden beds tidy, trimming overhanging plants, and reducing leaf build-up will keep your green cleaner and minimise routine maintenance. A well-maintained landscape also enhances the overall appearance of your backyard.
Enjoy Your Putting Green All Year
One of the biggest advantages of an artificial putting green is spending more time enjoying it and less time maintaining it. With simple routine care, your putting green will continue providing an enjoyable practice area for years to come.

Frequently Asked Questions
How much maintenance does an artificial putting green actually require?
Next to none. A quick 5-minute sweep or blow to clear off leaves and occasional cross-brushing to settle the sand infill is pretty much all it takes. You will never need to mow, water, fertilise, or roll the surface.
How often does the silica sand infill need topping up?
Silica sand settles into the dual-yarn matrix and rarely washes away thanks to our free-draining aggregate base. We recommend checking sand levels every 2 to 3 years and applying a light top-up only if needed to maintain optimal ball roll speed.
Can I use a pressure washer on my putting green?
We advise against using high-pressure washers directly on putting turf. High-pressure water blasts the rounded silica sand infill out of place and can disrupt the calibrated ball speed. A standard garden hose with a spray nozzle or a leaf blower is all you need.
How do I prevent moss on a shaded putting green?
Keep the green clear of damp organic debris like leaves. If your green sits in a dark, shaded spot during Kiwi winters, apply a mild, turf-safe moss treatment or gentle spray-and-forget solution that won't harm the PE/PP synthetic fibers.
Will weeds grow through the green?
No. Between our compacted aggregate metal foundation, geotextile weed barrier, and dense turf backing, weeds cannot penetrate from beneath. Airborne seeds that land on top can be easily pulled out by hand.
How does heavy rain affect maintenance?
It doesn't. Water drains rapidly straight through the turf backing and into the compacted aggregate sub-base. Once the rain stops, the surface dries quickly with zero mud, pooling, or surface damage.
