Bindi eradication/control

 


Hi everyone, I'm having bindi issues at the moment, and wondering what
the best
time to attack them would be. I've got some hortico bindi and
clover killer, but
there's a fair few popping up so I'm worried they
might be a bit too
established. any suggestions? Cheers, Josh.

I pull them out by hand.

Of course, it depends upon how large your yard is and how many you have, but
this guarantees that you don't kill anything else.  Also it's quite
cathartic (although you can get stabbed a bit if you're not careful...)

AFAIK you are supposed to use the bindi-specific sprays in late winter to
early spring (depending on your location) so that you get them when they
start the new season's growth but before they set out new thorns.  You may
have some seeds left over from last year that are coming up now too.

Glyphosate (roundup) kills just about anything

 


Any time before they flower and begin to set seed I'd say.  :-)
Wait until most of the seeds have sprouted so that you hit the lot if
you are going to spray. But I agree with others, start pulling some out
by hand. Aim to do 1 just sq m per day and see how you progress.

An eco-friendly method to get rid of clover, according to Graham Ross
(of Ch 7's gardening tv program) is to water with superphosphate solution.
The excess of nitrogen in the super overwhelms the clover (which can
synthesise all its nitrogen needs and this excess results in its death)
but its effect on other grasses that don't fix nitrogen is as a fertiliser.

Obviously you won't be seeing our Ch 7 programs there in the UK though.
