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.
