Dealing with Nettles/Thistles in a Paddock

It's not necesary to top them, grazon is good on nettles but slow on thistles.

Weeds'll be dead in a week, you probably could top then if you wanted to top

It wouldn't be left three weeks here in some paddocks. seems to work grand

An organic farmer tells me he sprays nettles on ffriday and mows them monday morning and it works grand.

You may be overthinking it

of course

i always praise grazon here, I don't know when i bought the litre i'm using now, maybe 2000, a knapsack full goes a long way here, I do the ditches on 100 acres and all the nettles and briars on our 10 acres. Sheep'll alway plant a few out in the fields from the ditches
