The best bindii weed killer is a selective broadleaf herbicide registered for bindii on your turf type, applied in late winter before the prickly seed burrs form. The biggest mistake is spraying in spring once the prickles are already there, because the weed dies but the burrs stay in the lawn.
This guide explains when to treat bindii, what to use and how to get rid of bindis without killing grass, plus the safe alternatives and when to call a professional.
Key points
- Bindii is a winter annual that germinates in autumn and sets prickly burrs in spring, so the best time to act is late winter to early spring.
- Use only a selective herbicide registered for bindii and your lawn type, and follow the label exactly, including protective gear and weather limits.
- In NSW, anyone who sprays weeds for fee or reward needs an EPA ground applicator licence, though routine lawn maintenance has an exemption.
- A Sydney gardener charges about $57 to $105 per hour for weed removal (October 2026), with a typical rate of about $75.
What are bindii plants? Bindi weed in Australia
| Term | Meaning | Why it matters |
|---|---|---|
| Bindii (bindi) | A low-growing winter annual weed with ferny leaves that spreads across Australian lawns | It is easy to miss in winter, then suddenly everywhere in spring |
| Bindii prickles | Hard, spiky burrs that form at the base of the plant as it matures | They hurt bare feet and pets’ paws, and they remain after the plant dies |
| Selective herbicide | A product that targets broadleaf weeds and leaves registered lawn types alone | It is how you control bindii without killing grass |
| Pre-emergent | A product applied before seeds germinate to stop new plants | Autumn timing stops next year’s bindii |
| Registered product | A herbicide approved for a specific use, listed on its label | Off-label use is unsafe and illegal |
When to use bindii weed killer in Sydney
| Season | What to do | Why |
|---|---|---|
| Autumn (March to May) | Check the label for a pre-emergent suited to your lawn, and thicken thin patches | Bindii seeds germinate as the soil cools |
| Winter (June to August) | Spot-spray small plants with a registered selective product when conditions suit | Young plants are easiest to control before they flower |
| Late winter to early spring (August to September) | Make your final treatment before burrs form, then mow and bag the clippings | Stops the burrs developing in the lawn |
| Spring (September to November) | Hand-pull or rake out burrs, and wear shoes on the lawn until they are cleared | Spraying now kills the weed but leaves the prickles |
| Summer (December to February) | Keep the lawn thick and watered, within Sydney Water’s Water Wise Guidelines | Bindii dies off, and a dense lawn crowds out next year’s seedlings |
What you need to get rid of bindii in grass
| Item | What it is for | Tip |
|---|---|---|
| Selective herbicide for bindii | Kills bindii and other broadleaf weeds in lawns | Check the label lists your grass, since buffalo, kikuyu and couch can react differently |
| Pump-pack or hose-on sprayer | Applies the product evenly | Rinse thoroughly after use and keep it away from drinking containers |
| Gloves, eye protection and long sleeves | Protective gear listed on the label | Wash clothes separately after spraying |
| Hand weeder or garden fork | Removes small patches by hand | Work when the soil is damp so roots come out |
| Lawn rake or leaf rake | Lifts burrs and dead plants | Bag the waste rather than composting it |
| Mower with a catcher | Collects burrs and seed heads | Mow within NSW noise hours and keep the blade sharp |
Bindii weed killer: step by step
- Identify the weed first, looking for low, fern-like rosettes with tiny burrs at the base, usually appearing in July and August.
- Read the product label and confirm it names bindii and your grass type; do not use any product off-label.
- Mow the lawn a day or two before spraying so the weed leaves are exposed to the product.
- Put on gloves, eye protection and the other protective gear the label lists, and keep children and pets inside.
- Choose a calm, dry day with no rain forecast, and never spray in wind, because drift harms garden beds and neighbours’ plants.
- Apply exactly as the label directs, and keep runoff out of drains, gutters and waterways.
- Keep children and pets off the area until the label says it is safe to return.
- Wait before mowing again as the label directs, then rake and bag any burrs that remain.
- Repeat only if the label allows, and fertilise and water the lawn afterwards so it thickens up.
Bindi herbicide and bindii spray: what kills bindis but not grass
Selective broadleaf products are the only chemical option that targets bindii without killing grass. Warm-season lawns on the Northern Beaches and in the Inner West are mostly buffalo, kikuyu or couch, so check the label for your variety.
- Choose a product that names bindii and your lawn species, because some turf is sensitive to broadleaf herbicides.
- Look for products from trusted Australian brands such as Yates, Searles, Scotts or Hortico at Bunnings, and read the whole label before buying.
- Do not mix products or add extras, and never apply more than the label allows.
- Avoid spraying new turf or lawns under stress; check the label for waiting times after laying or reseeding.
- Keep sprayer overspray away from garden beds, vegetable patches and tree roots.
How to get rid of bindis without killing grass: other options
Chemical control is not the only option, especially for small patches or families with pets.
- Hand-pull small patches while the weeds are young and the soil is damp, then bag them.
- Mow regularly and collect clippings in late winter to remove seed heads before they harden.
- Thicken the lawn with correct feeding, watering and aeration so bindii has less bare ground to colonise.
- Skip home remedies: vinegar, salt and bleach are non-selective and can damage soil and nearby plants, with salt and bleach harming soil long term.
- Read how to kill weeds naturally to see the trade-offs of each method before you try one.
How to get rid of prickles in lawn after bindii dies
Dead bindii leaves the prickly burrs behind, which stay a hazard to bare feet until you remove them.
- Rake the lawn firmly in two directions to lift burrs and dead plant material.
- Mow with a catcher fitted and empty it into the green waste bin, not onto garden beds.
- Vacuum or sweep paths and driveways where burrs have blown, and clean pet paws after walks.
- Keep the lawn off-limits to children and pets until the burrs are cleared.
- If your pet has sore paws or is limping, speak to your vet.
Common mistakes with bindii weed killer
- Spraying too late in spring, when burrs have already formed and the prickles stay in the lawn.
- Using a product that is not registered for bindii or your turf type, which can burn or kill the grass.
- Spraying in wind or before rain, which wastes product and sends runoff into drains and waterways.
- Mixing products or exceeding the label directions, which is unsafe and not permitted.
- Applying weed and feed to stressed lawns, which can harm the grass; see our weed and feed guide for details.
- Skipping lawn recovery, so thin patches let the next crop of bindii take hold.
When to call a gardener or licensed specialist for bindii
- You have a large lawn or steep block and cannot safely spray or rake the whole area.
- You want paid weed spraying, since in NSW anyone spraying weeds for fee or reward needs an EPA ground applicator licence (routine garden maintenance has an exemption).
- Your lawn is thinning from other causes, so book a lawn care visit to look at feeding, aeration and mowing height.
- Weeds keep returning each year and you want a proper seasonal plan from a local gardener.
- You have lawn grubs or other pests, in which case book a licensed pest controller instead of treating them yourself.
- Large trees or tree roots are involved, which is a job for a qualified arborist after you check your council’s tree rules.
