Nothing ruins a classic Australian backyard summer quite like stepping barefoot on a Bindii prickle. These low-growing, invasive weeds are the absolute nemesis of Aussie lawns, turning a relaxing afternoon into a painful experience for kids, pets, and adults alike.
The trick to a prickle-free summer is catching the Bindii early. At AussieHomeFix, we have outlined the ultimate guide to identifying, treating, and permanently getting rid of Bindii weeds in your lawn.
What is Bindii and When Does it Grow?
Bindii (also known as Jo-Jo weed) is a broadleaf weed that grows close to the ground. It features small, fern-like green leaves. During winter and early spring, it grows flat and goes mostly unnoticed. However, as late spring and summer approach, it produces small green seed pods that eventually dry out and harden into those sharp, painful prickles.
Step 1: Hand-Pulling (For Small Infestations)
If you only have a few Bindii patches in your lawn, hand-pulling is the safest and most environmentally friendly method. The best time to do this is in late winter or early spring before the seed pods harden.
- Put on a pair of thick gardening gloves.
- Use a small weeding tool or an old butter knife to dig slightly under the center of the weed.
- Ensure you pull out the central taproot completely, otherwise, the weed will simply grow back.
- Throw the pulled weeds directly into the green bin, not the compost, to prevent seeds from spreading.
Step 2: Herbicide Treatment (For Large Infestations)
If your lawn is heavily infested, manual pulling won't be enough. You will need to use a selective broadleaf herbicide. Timing is critical here: you must spray in late winter or early spring (August to September) while the plant is actively growing but before it sets seeds.
Important Note for Aussie Lawns: Always check that the herbicide is safe for your specific grass type. While Couch and Kikuyu lawns can tolerate most broadleaf weed killers, Buffalo grass (like Sir Walter) is highly sensitive. You must use a weed killer explicitly labeled "Safe for Buffalo" (usually containing Bromoxynil and MCPA instead of Dicamba) to avoid killing your entire lawn.
Step 3: Prevent Bindii from Returning
Bindii thrives in compacted, nutrient-poor soil and loves a lawn that is cut too short. The best defense against weeds is a thick, healthy lawn that naturally chokes out invaders.
- Raise the mower blades: Leave your grass slightly longer (around 4-5cm) to shade the soil and prevent weed seeds from germinating.
- Aerate your lawn: Use a garden fork to aerate compacted areas, improving water and nutrient flow to the grass roots.
- Fertilize regularly: Apply a high-quality, slow-release fertilizer in spring to encourage rapid, dense grass growth.
Final Thoughts
Getting rid of Bindii takes a bit of timing and patience, but treating your lawn in early spring guarantees a soft, prickle-free backyard by December. Don't wait until you step on one to take action!
