How to Get Rid of Bindii Before Barefoot Season

Nobody looks up how to get rid of bindii in August. Everyone looks it up on the first warm Saturday in November, usually about two seconds after standing on one in bare feet. That is the whole problem with this weed: it is invisible when it is easy to fix and unmissable when it is not.

The good news is that right now, in the back half of winter, is the best window you will get all year. Here is how we handle it.

When should you spray bindii?

Spray bindii in winter, from about mid-June onwards, once the leaves have formed but before it flowers and sets those prickly seed pods. That is the entire trick. In winter it is a soft little fern-looking rosette with no defences. By the time it has prickles, the plant has already done its job and dropped next year's seed, so killing it in December stops the pain but does nothing about next season.

In the Hills, that means you have roughly until the end of August to get on top of it comfortably. If you are reading this in early spring, treat it anyway, just expect to be dealing with it again next winter too.

What kills bindii without killing buffalo?

Check the active ingredient, because the common ones are not all buffalo safe. Broadleaf weedkillers containing dicamba will knock over bindii and clover in couch and kikuyu lawns, but they are not suitable for buffalo. For a buffalo lawn, which is most of what we see around Kellyville and Castle Hill, look for a bromoxynil based product instead, sold as a buffalo safe bindii and clover killer.

If you are not sure what grass you have, that is worth sorting out before you buy anything. The wrong bottle on a buffalo lawn does more damage than the weed did. Yates and Bunnings both list which products suit which lawn type, and the label on the bottle is the final word. Read it properly, mix it at the stated rate, and keep kids and pets off until it has dried.

Expect seven to ten days for the plants to yellow off and collapse. It is not instant and it is not dramatic. You will walk out the morning after spraying, see nothing, and assume it did not work. Give it a week.

Will one spray be enough?

Usually not. Bindii germinates in waves through winter, so the batch you killed in June is not the batch coming up in July. The standard approach is to repeat every three weeks or so until you stop seeing new rosettes. Two or three passes across the winter is normal for a lawn that has had it badly.

What if you have missed the window?

If the prickles are already there, mowing with the catcher on is your best short term move. It lifts and removes a lot of the seed heads before they drop, which takes the sting out of the lawn now and reduces what germinates next winter. It will not fix the problem, but it buys you a usable backyard for summer.

Then put a note in your phone for June. Genuinely. That one reminder is worth more than anything you can buy in a bottle.

Can you get rid of bindii without spraying?

Yes, if the patch is small. Bindii pulls out easily by hand while it is young and the soil is damp, roots and all. A winter afternoon and a kneeling pad will clear a few square metres without a drop of chemical. Where hand weeding falls over is a whole lawn that has been left for a couple of seasons, at which point you are looking at thousands of plants and a very sore back.

Keep the lawn thick. Bindii is an opportunist, not a bully. It moves into bare patches, thin edges, scalped strips and the compacted line where everyone walks to the bin. A dense lawn simply gives it nowhere to land.

That means the boring stuff, done consistently:

• Mow at the right height and never take more than a third of the leaf in one go. Scalping opens the door.
• Feed the lawn at the start of spring and again in early autumn so it fills in on its own.
• Patch bare spots rather than waiting for something to volunteer, because something always will.
• Water deeply and less often so the roots go down instead of sideways.

Everyone's got that one patch by the letterbox that never quite recovers. That is where bindii lives. Fix the patch and you fix the weed.

The honest summary

Bindii is a calendar problem more than a chemical problem. Treat it in winter and it is a twenty minute job. Ignore it until the prickles arrive and you have lost the year. If you would rather it was simply handled, that is the kind of thing that comes with a regular visit. Have a look at our garden maintenance or lawn mowing pages, or get in touch and we will take a look at what you are actually dealing with. There are a few more garden guides here if you are the do it yourself type, which plenty of our customers are.

No pressure either way. Just get it before November.
