Have you tried Bindi spray or Weed & Feed types?
I googled it and Farmers do acres of killing Bindis by applying Sulphate of Amonia.....sprinkle on leave 2-3 days do not water it,it burns them.After 3 days give a good watering, 4 weeks later they suggested to use organic furtilizer to balance the soil back to normal. They say the turf grows a hundred mile an hour(nitrogen in the S/A) so be ready for some serious lawn mowing!!! :D
Just realised you have "Burrs" are they same & one as Bindies?
Thanks, yes it is actual bindii, with the round spiky balls. I assume this method is safe for my cocker spaniel? If so, it sounds good, don't know what my husband thinks of extra lawn mowing, already takes 2 hours. Still better than getting out the rotten bindies from my pup's long hair. Will give it a go.
Thanks heaps.
