$93.87 on AmazonBuying guide: choosing a safe, effective flame weeder
- Australian LPG compatibility: Look for clear mention of a reverse‑thread POL valve/connection for 9 kg bottles. Some torches use 1 lb cylinders or other connectors — confirm before buying.
- Ignition: Built‑in piezo/button ignition avoids juggling a lighter near gas.
- Hose length and reach: A 3 m (10 ft) hose keeps the bottle away from heat and improves manoeuvrability. Adjustable wands reduce back strain along long paths.
- Flame control: A fine control valve plus a turbo trigger gives a small, precise pilot for cracks and a wider flame for open joints.
- Output and nozzle size: Higher BTU and larger heads speed up work on broad, weedy joints. Use the lowest effective flame for safety and fuel economy.
- Certifications and fittings quality: cCSAus/CSA listings, brass fittings and robust hose help with durability and safety.
- Ergonomics: Non‑slip handles and balanced wands are easier to control on slopes and steps.
How to flame‑weed paths & pavers safely in Australia
- Check fire conditions: Do not use during high fire danger periods or on total fire ban days. Follow your state’s rural fire service guidance (RFS/CFA/CFS/DFES/QFES/TFS/NTFRS).
- Prep the area: Blow or sweep away dry leaves. Lightly pre‑wet adjacent lawn/edges and keep a hose or extinguisher within reach. A retractable hose reel makes this quick.
- Use a pilot‑sized flame: You’re scorching, not incinerating. Pass the flame so foliage wilts/darkens in 1–2 seconds. Overheating can damage pavers, edging or bedding sand.
- Mind the surroundings: Avoid flame on mulch, timber sleepers, plastic edging or exposed drip lines. Don’t torch near gas bottles or stored fuels.
- Moss & lichen on pavers: Heat until it steams and loosens, then lift residues with a broom or a pressure‑washer surface cleaner. Test discreetly on natural stone to avoid thermal shock or spalling.
- Follow‑up cadence: Expect regrowth from root reserves; quick repeat passes every 1–3 weeks in the growing season keep joints clear without chemicals.
Hardscape weed prevention ideas
- Under‑paver barrier: When relaying paths or topping gravel, use a heavy‑duty woven weed barrier and compact bedding sand well. See plate compactors for paver patios.
- Edge control: Proper metal landscape edging stops lawn runners creeping into joints.
- Drainage: Standing water encourages moss; improve falls or add drains. Our yard drainage solutions guide can help.

FAQs
- Will a flame weeder kill roots?
- No. The goal is to heat plant cells so tops wilt and die back. Deep roots often reshoot; quick repeat passes keep cracks clear without chemicals.
- Can I use a flame weeder on lawn weeds?
- Not recommended. You’ll scorch the grass. For lawns, consider selective herbicide strategies instead; see our guides such as bindii control or clover in lawns.
- Are these torches compatible with Australian LPG bottles?
- Models that state a reverse‑thread POL valve/connection are intended to mate with common Australian LPG cylinder fittings. Always confirm the product’s stated connector before purchase.
- Do I need a regulator?
- Many kits include a hose and valve assembly matched to the torch. Use only the fittings supplied or specified by the manufacturer; do not mix unverified regulators or adapters.
- Is it safe on concrete and clay pavers?
- Brief scorch passes are generally fine. Avoid prolonged heating, especially on natural stone. Test in a small area first and use the lowest effective flame.
- What about windy days?
- Avoid use in wind. Flames are harder to control and embers can travel. Postpone work in hot, dry or windy conditions and never use on total fire ban days.
