What is the best way to deal with nettles/thistles in a paddock? Should you spray with Grazon and then top them a while later? Or any better ways? How long should you leave it after spraying them? All suggestions welcome.
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
a week is too soon to top as the chemical is still being transferred to root system and you won't get long acting control,
mix & apply as recommended and leave 3 weeks b4 cutting.
It wouldn't be left three weeks here in some paddocks. seems to work grand
5 years time will tell the difference but if you're happy mow away.
An organic farmer tells me he sprays nettles on ffriday and mows them monday morning and it works grand.
You may be overthinking it
😆 He is spraying vinegar and petal juice we assume
Spray here every 6 to 7 years
See the local know all spraying every second or third year and then complaining that the spray is useless. Not because of mowing but because of mixing too strong and the plant is dead before the chemical penetrates the root system
Spray suppliers love fellows like him ( and yourself)
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
