NZLA Moss – Lawn Moss, Lichen and Algae Control

NZLA Moss is a professional-grade moss and algae control product designed to keep lawns, garden beds, and hard surfaces clean and healthy.

Key benefits

• Controls moss, lichen, algae and liverwort on lawns and garden surfaces
• Works quickly – moss and lichen begin to die within hours under good conditions
• Suitable for use on lawns, driveways, paths, and patios
• Safe for most established lawn types including ryegrass, fescue, couch, kikuyu and buffalo
• Doesn’t stain concrete, pavers or stone when used as directed
• Available in multiple sizes to suit home and professional users

How it works

NZLA Moss contains benzalkonium chloride, a fast-acting biocide that kills micro-organisms on contact. It penetrates moss and algae cells, breaking down their structure and causing rapid die-off. It’s absorbed quickly, usually within 5 to 15 minutes for moss and within hours for lichen and algae.

The product forms a protective surface layer that helps slow regrowth and keeps lawns and hard surfaces cleaner for longer.

Application directions

• Lawn application: Mix 200-500ml in 10L of water, covers 100m²
• Lawn 20–50 mL of product in 1L of water and apply evenly over 10 m².
• Garden beds, paths and hard surfaces: Mix 10–30 mL per litre of water depending on infestation.
• Apply evenly to a dry surface and ensure full coverage.
• Do not water or irrigate for at least 12 hours after spraying.
• Repeat as needed for heavy or persistent growth.
• Rinse off any accidental contact with desirable plants within five minutes of spraying.
• Keep pets and children off treated areas until the surface is dry (ideally 24 hours).

Application notes

The lower end of the rate (around 200 mL per 10 L water) is suitable for light or early-stage moss growth, where you’re mainly aiming to suppress and prevent regrowth. The higher rate (around 500 mL per 10 L) is intended for heavy, well-established moss where you need stronger surface coverage and deeper penetration to get full desiccation and kill.

DO NOT TANK MIX – Low mixing compatibility.

Safety notes

• Avoid spraying near ponds, streams or drains – toxic to aquatic life.
• Always wear gloves and eye protection during application.
• Do not mix NZLA Moss with fertilisers or wetting agents.
• Store in a cool, dry place away from food and animal feed.
