Buffalo grass (Stenotaphrum secundatum) is a popular warm-season turfgrass in Australia, known for its drought tolerance, low maintenance, and soft texture. It thrives in hot climates, making it an excellent choice for lawns in the Gold Coast and other subtropical regions.
However, even the hardiest buffalo grass can fall victim to invasive weeds. To maintain a lush, green lawn, understanding the right herbicides and how to use them is essential.
Common Weeds Affecting Buffalo Grass
Several weeds compete with buffalo grass for nutrients, sunlight, and water. The most common offenders include:
Bindii (Soliva sessilis): A prickly weed that causes discomfort underfoot.
Clover (Trifolium spp.): A nitrogen-fixing plant that spreads quickly.
Wintergrass (Poa annua): A cool-season grass that invades buffalo lawns in winter.
Crabgrass (Digitaria spp.): A fast-growing weed that thrives in summer.
Dandelions (Taraxacum officinale): Deep-rooted weeds that are difficult to remove manually.
Choosing the Right Herbicide for Buffalo Grass
Not all herbicides are safe for buffalo grass. Some chemicals can damage or kill the turf, so choosing a buffalo-safe herbicide is crucial. Key factors to consider:
Selective vs. Non-Selective: Selective herbicides target specific weeds without harming buffalo grass, while non-selective herbicides kill all vegetation.
Pre-emergent vs. Post-emergent:
Pre-emergent herbicides prevent weed seeds from germinating.
Post-emergent herbicides kill existing weeds.
Chemical vs. Organic: Synthetic herbicides work faster, but organic options are safer for pets and the environment.
Selective vs. Non-Selective Herbicides
| Type | Best For | Examples |
|---|---|---|
| Selective | Killing weeds without harming buffalo grass | Bow & Arrow, Buffalo Pro, Bin-Die |
| Non-Selective | Total vegetation control (use carefully) | Glyphosate (Roundup), Eco-Hoe |
Important: Non-selective herbicides should only be used for spot treatment, as they can kill buffalo grass if applied broadly.

How to Apply Herbicides Safely and Effectively
To maximise effectiveness and minimise harm:
Check the Weather
Avoid applying herbicides before rain, as it can wash away the product.
Apply during calm weather to prevent drift.
Follow Label Instructions
Use the recommended dosage: overapplication can damage buffalo grass.
Spot-Treat Weeds
For small infestations, use a spray bottle or brush to apply herbicide directly to weeds.
Water the Lawn First
A well-hydrated lawn recovers faster from herbicide stress.
Avoid Mowing Before/After Application
Wait at least 48 hours before and after herbicide application.
Preventative Measures for a Weed-Free Lawn
The best defence against weeds is a thick, healthy lawn. Follow these tips:
- Mow at the Right Height (3–5 cm for buffalo grass)
- Fertilise Seasonally (use slow-release fertilisers)
- Aerate Compacted Soil (improves root growth)
- Water Deeply but Infrequently (encourages deep roots)
- Overseed Bare Patches (prevents weed invasion)
